NASA, Alaska officials see new uses for airships

Published    August 23, 2012                   Copyright by the Associated Press

A California company will fly its airship up Alaska's Inside Passage and all the way to Anchorage next year if it can line up sponsors. Lighter-than-air aircraft advocates say such vessels may one day be a common sight, delivering fuel or construction material to remote Alaska villages or food to hungry people on another continent.
S. Pete Worden, director of NASA's Ames Research Center, said his agency is offering its expertise and technology to the fledgling industry, which has important applications for science and for delivering cargo to hard-to-reach destinations.
"Airships appear to us to be an industry about to take off, if you'll pardon the pun," he said. Worden spoke Wednesday at the second Cargo Airships for Northern Operations Workshop, which brought together airship builders and representatives of mining, petroleum and communication companies who operate off the grid in Alaska. 'Airships appear to us to be an industry about to take off, if you'll pardon the pun.', Worden commented.
NASA's roots, Worden said, are in aeronautics and helping develop new industry. Working with Airship Ventures, whose 246-foot helium-filled Zeppelin is based at Moffett Field outside San Francisco, NASA has concluded that hovering airships are a valued tool for climate studies, earth science and astrophysics research.
They also fit the bill for a major new NASA initiative — developing "green aviation" that puts fewer greenhouse gases in the atmosphere than cargo jets, Worden said.
Alaska Lt. Gov. Mead Treadwell said the state is a "ready-made market for airship technology." Alaska has 200 villages off the road system that need lower-cost cargo deliveries. Airships also could provide alternative transportation for industries that want to cross environmentally sensitive wilderness.
Industry expert Ron Hochstetler, who helped organize the conference, said airship cargo delivery is not competitive with trucks on interstate highways or cargo ships. Airship cargo's per ton cost fits between cargo airplanes and surface transportation.
The industry is at a tipping point, Hochstetler said. Airship cargo technology can deliver tens of tons, and customers have indicated that they are interested, but both sides need to connect on specifics.
"We're bringing that market closer and closer to the providers of the ships and the services," he said.
Francis Govers, special missions manager for Airship Adventures, said his company has planned a tentative route to fly its 246-foot helium-filled Zeppelin airship to Alaska next June and will decide by the end of the year if it lines up industry partners. Cruise ship companies and documentary makers are possibilities for joint ventures, he said.                                     -------------------------------------------------------------------------------------                                    BLOG Editor's note by Hal Pelta :

We know that this news is three months old, but it's worth reprinting here in the BLOGOSPHERE, as

1. it is an important and significant bit of news .

2. not everyone receives Fox News or the Associated Press .

3. So much other significant news has gotten lost in the daily stories about the various poitical high jinks in the United States .

4. We would like to formally recognize the years of ground-breaking work along the same lines by Dr. Barry Prentice, the Founder of ISOPolar and on the faculty at the University of Manitoba

Dr. Prentice has spent much  of his professional tying the use of airships to logistics in the Arctic and sub-Arctic regions of Canada (with good reason and with good results) . We at Airship Universe would like to break new ground by reminding airship interests that there are three worlds of involvement that dearly need focus :
First, the vast geographies of other regions equally devoid of infrastructure for shipping and receiving vital materiel (rain forests, the still largely unexplored areas of the southwest Pacific, the deserts of the world, and so on , AND
Second, the many non-military uses unrecognized even by practitioners in these fields, such as domestic agriculture; marine biology (where the applications are being attended to by Autonomous Underwater vehicles and remotely operated submarines", AND
Third, the many small but vital research projects that can benefit from the use of small unmanned airships , projects that are of a much smaller magnitude that the multi-million dollar projects supported by the military .

China Eyes Greenland's Natural Resources : it all comes down to Hydrogen and Airships


Folks, here's what Dr. Barry Prentice of the University of Manitoba in Canada and I have been talking about for a few years : exploitation of the incredible mineral wealth of the Arctic and, in particular by Dr. Prentice, the very difficult logistics of supply and  transportation required to utilize it. The following Reuters news story just came across the Internet wires . ... and we want to remind our readers that the Arctic is NOT the only place on earth which features such riches;  many others lie in inaccessible areas, with difficult terrain and little or no transportation.
How can we get our legislators to listen and understand the critical importance of these assets? Some countries want nothing less than complete market control of some of these strategic resources.
The best way for us to transport them from inhospitable climes to industrial users : Airships . Let's wake up our sleeping officials and get them moving on solutions ! Here's the original Internet story :

REUTERS: Michael Kappeler. File: China looks toward
Accessing Greenland's  iron, zinc and rare earth mineral resources.
6 hr ago                              By Alistair Scrutton of Reuters
China and Greenland may seem to make strange bedfellows, until scratching below the surface to reveal rich mineral deposits that would benefit China's growing need.
NUUK - By a remote fjord where icebergs float in silence and hunters stalk reindeer, plans are being drawn up for a huge iron ore mine that would lift Greenland's population by four percent at a stroke - by hiring Chinese workers.
The $2.3-billion project by the small, British company London Mining Plc would also bring diesel power plants, a road and a port near Greenland's capital Nuuk. It would supply China with much needed iron for the steel its economy demands.
With global warming thawing its Arctic sea lanes, and global industry eyeing minerals under this barren island a quarter the size of the United States, the 57,000 Greenlanders are wrestling with opportunities that offer rich rewards but risk harming a pristine environment and a traditional society that is trying to make its own way in the world after centuries of European rule.
Great expectations could lead to greater disappointments, for locals and investors. Yet a scramble for Greenland already may be under way, in which some see China trying to exploit the icebound territory as a staging ground in a global battle for Arctic resources and strategic control of new shipping routes.
Whether in iron, zinc or rare earth minerals vital for 21st-century technology like smartphones, China, the emerging economic superpower is eyeing investments in the Danish-ruled country whose own, increasingly autonomous, national government is looking further afield for investors.
"This is not just a region of ice and polar bears," Prime Minister Kuupik Kleist told Reuters in the capital Nuuk, formerly known by its Danish name Godthab. "Developing countries are interested in a more political role in opening up of the Arctic. Greenland could serve as a stepping stone."
Talk in Europe or North America of a Chinese grand design to take over the Arctic is mocked as overblown by many in Greenland - an recent exhibition of cartoons recently in Nuuk featured one drawing of an iceberg, Greenland-shaped above the water line, and in the form of China below. Its caption: "Polar Paranoia".
Compared to its investments in Africa or Latin America, Beijing has a light footprint in the Arctic. In Greenland, not one mining or oil project has yet gotten off the ground. Appetite for exploration is tempered by political polarization, as Greenland's leaders square off over how to regulate and tax new wealth under a self-government regime just three years old.
"There are great expectations in Greenland, but no results," said Rasmus Ole Rasmussen, a senior researcher specializing in Arctic affairs at the Nordregio institute in Stockholm.
Nonetheless, transformation is approaching rapidly for a land still mostly inhabited by indigenous Inuits engaged in an economy dominated by fishing. And China may play a larger role in this than Europeans and North Americans find comfortable.
"It's fair to say countries like China and South Korea are far more active than Americans and Europeans in showing their interest in investing," said Kleist, who adds that the West, for which Greenland remains part of its Cold War-era NATO defense pact, can appear complacent, despite new geopolitical currents.
In Nuuk, home to 16,000 people on the southwestern coast, 1,000 sea miles north of Newfoundland, there are just two traffic lights. But new construction is everywhere: gleaming office buildings that house foreign companies and even a new mall where one can buy olives and French cheeses - for a price.
Greenland's Bureau of Minerals and Petroleum (BMP) has now awarded overall some 150 licenses for mineral exploration compared with only a handful in existence a decade ago, with around $100 million spent by companies last year alone. Oil companies have spent more than $1 billion in exploring offshore. That includes exploration of rare earth minerals, used in products from wind turbines to hybrid-powered cars. China currently accounts for the vast majority of the world's supply.
UNFROZEN NORTH
Greenland can look like ground zero for global warming. This summer many scientists were shocked as nearly all its massive ice sheet thawed. Hunters no longer prowl offshore ice that has grown too thin to support their dog sleds. A walrus was the talk of Nuuk this year, found drifting far south of its normal range.
But there also benefits from warmer weather - and it is not just dreams of growing strawberries and broccoli in the south.
With ice receding, some estimates suggest the polar ice cap may by 2040 be disappearing entirely during summer. Melting sea ice may open passages north of Canada and Russia and cut sailing distances by up to 40 percent between Shanghai and New York.
"Greenland used to be a big, white blob on the world map," said Aleqa Hammond, an opposition leader and former foreign minister of Greenland. "Now we have a global role."
But she criticized the government for keeping people in the dark about Chinese plans: "We see Chinese delegations everywhere and even the parliament does not know who they are," she said. "We see them in our hotels, in our fjords and on our streets."
London Mining plans construction at the Isua iron ore deposit next year if Greenland gives the go-ahead. The project, which aims for finance from China, would ship some 15 million metric tons of iron ore annually from fjords near Nuuk to China.
CHINA'S GHOST
An icebreaker completed China's first crossing of the Arctic Ocean this past summer, and diplomacy earlier in the year has also underlined China's interests in the north Atlantic.
Premier Wen Jiabao began a tour of Europe in April with a visit to Iceland, population 320,000, where there has been much talk of a Chinese developer's bid to lease a vast tract of land.
And it was little surprise when President Hu Jintao, leader of the world's most populous nation, paid a three-day visit in June to Denmark, home to just six million people. Many assumed Greenland's riches were on his mind, despite official denials.
Just days before, EU Industry Commissioner Antonio Tajani had flown to Nuuk to sign a letter of intent to cooperate with Greenland on its raw materials: "The letter of intent," said one senior Greenland official, "Was a political message that we would not lock ourselves into supplying China with minerals."
In Greenland, Kleist spoke of European pressure, saying one EU politician had suggested he limit Chinese mining. The prime minister, whose nation is not part of Denmark's membership of the European Union, refused, saying modern trading rules would not allow it: "Could the EU do that?" he asked. "Of course not."
When U.S. Secretary of State Hillary Clinton visited last year, her bodyguards worried at the near absence of security measures in Greenland. But she had other things on her mind: "One of her first questions was, 'What is happening about rare earths?'" said a Greenland government official.
At last : one bright, wide awake, knowledgeable government official, who understands what might be going on and its possible significance.                                               HYBRIDPELTA  
One deposit alone, in southern Greenland, being explored by Australia's Greenland Minerals and Energy, could contain more than 10 percent of the world's deposits of rare earths. Oil could have an even greater impact.
Rare earth  minerals may not be all there is of strategic value :
Energy consultancy Wood Mackenzie says Greenland may have reserves of 20 billion barrels of oil. The BMP says reserves may be equivalent to as much as half of the entire North Sea. [Editor's addition in RED]
Greenland has approved a sovereign wealth fund on oil-rich Norway's model that would allow it to invest new earnings.

GREENLAND'S "HOLY GRAIL"
Yet a big question is whether such a tiny population can cope, and there are signs of local political unease that may hinder investment, whether Asian or Western.
Four hours north from Nuuk by ship, through melting icebergs and passing whales, lies Maniitsoq, a symbol both of the hope foreigners bring and a reality check for Greenland's ambitions.
U.S. giant Alcoa Inc is considering building an aluminum smelter there, strategically sited between European and North American markets. It would entail the import of thousands of workers, possibly from China.
Why not from the United States OR from the European Union ??
The smelter would be fed from mines as far apart as Brazil and Australia and shipped out as aluminum to the world market. Alcoa has not decided to go ahead. Among several pending issues, it wants to see whether cheaper foreign labor will be allowed .             
A-a-a-a-h  ! Now I see ! BUT are we looking at just another settlement of workers with very low wages ---  to save money ---   or is another possibility the establishment of what is essentially a  colony ? I'm asking out of caution, not paranoia !
After it won greater self-rule in 2009, an annual grant from Denmark which has covered more than half of Greenland's public spending was effectively frozen at around 3.5 billion Danish crowns ($600 million) and will shrink in real value over time.
"There is a need to become independent economically," said Naaja Nathanielsen, a Greenland lawmaker. "Most people see it not as opportunity, but as necessity."
Villages like Maniitsoq are dotted along Greenland's western coast, relying on state subsidies for heating and communications. Unemployment is high and alcoholism rife.
Much of the Maniitsoq fisheries industry has vanished. Locals say shrimp have moved north as southern waters warm. The town is huddled on an outcrop of windswept rocks with Soviet-style housing blocks, empty streets and a few downtrodden bars. "We need a Big Bang here," said Karl Lyberth, deputy major in Maniitsoq. "Alcoa is the only project that can help us. The town's population, now 2,715, has fallen by around 200 in a decade. Few will speak against Alcoa, though a local hotel owner made headlines that were uncomfortable for some by saying the town would need a brothel for workers building the smelter.
"It was only half a joke," said Soren Lyberth of the Heilmann Lyberth Hotel. "But people don't want to talk about it."
He touched a sore point in Greenland - some fear that the country cannot absorb so many dollars and foreign workers, and that untrained and poorly educated Greenlanders will lose out.
"They think the holy grail is Alcoa, but it's not true," said Jens Moller, head of a community training project in Maniitsoq. "It could bring a lot of problems."
ENVIRONMENTAL HESITATION
Locals also debate bringing in 2,000 Chinese workers to Nuuk for London Mining, and whether Greenland should let foreign employers undercut local wages. Such arguments stall projects.
To the dismay of investors, a consensus behind foreign companies has frayed. The opposition is calling for more taxes on miners. Environmentalists demand more consultations.
"We need more royalties," said opposition leader Hammond. "The polluter should be paying."
The leftist, pro-independence coalition led by Kleist has more technocratic ministers than a previous government criticized by opponents as nepotistic and inward-looking.
But Kleist, born to an Inuit mother and Danish father in a now abandoned mining village, is aware of communities' problems and his coalition is split on whether to let in low-paid foreign labor. Several mining executives and Greenland officials expressed frustration at the slow pace of projects.
"Our dream is about to come true," said one senior Greenland official, who spoke on condition of anonymity. "But people are getting nervous, asking whether they are ready for this."
Take rare earths. Because they are massed with uranium, neither could be mined without ending Greenland's prohibition on extracting radioactive materials - a policy inherited from Denmark. Greenland's politicians are split on the issue.
"The policy of zero tolerance is the main issue for us," said Ib Laursen, operations manager at Greenland Minerals and Energy. Only by ditching the ban could his project be feasible.
Today there is only one operational mine in Greenland, a gold deposit, which opened in 2004. Oil drilling in 2010 and 2011 has failed to yield any discoveries despite a $1.2 billion campaign led by Britain's Cairn Energy .
While Greenlanders wait for any bonanza to start, the notion that it may bring Chinese dominion seems far-fetched to many in a country whose European links stretch back a thousand years to Viking colonists and whose ties to the Americas include the Cold War-era U.S. Thule Air Base, deep inside the Arctic Circle.
Some analysts say China's role in Greenland is exaggerated - and that its ambitions are more economic than geopolitical:
"Many non-Arctic countries, like in Europe, are seeing ghosts and troubles ahead," said Rasmussen at Nordregio, describing such fears as having "little to do with reality".
Greenland's prime minister also stresses the limits to his ambitions for the pace of development: "Our situation is uncertain," said Kleist. "I would say five projects in 10 to 15 years are realistic in terms of the global economic situation and the capacity of Greenland society."
Among capacity constraints are concerns over its ability to protect an ecosystem which, global warming aside, is largely unsoiled by human industry. Some big oil executives say it is simply not worth the risk of a spill to drill in a region where its effects could be devastating and clean-up facilities scarce.
For Mikkel Myrup, chairman of local environmental group AvataQ, the country is unready for industrial development: "Greenland simply does not have the regulatory capacity to take responsibility for monitoring the industry," he said.
Standing on a cliff in Maniitsoq, hotelier Lyberth has put off building a new hotel with a view of snow capped mountains. Alcoa and its foreign executives, for the moment, seem far away. "This is my dream," he said, smiling as he pointed to a barren piece of flat rock where the hotel would be. "But so far it's only a dream."

Up, Up, and Away! World's largest airship lifts off for the first time

By Claire Bates, Original remarks reported and published in the Daily Mail

UPDATED: 09:00 EST, 25 June 2012 :                                                                                               BLOG Editor's comments in RED, 10 October 2012  
More than 70 years (actually, 75 years) after the Hindenburg disaster ended the golden airship era, giant blimps will take to the skies again with the launch of the world's largest inflatable craft. See : U.S. Navy, which never gave up on using them. ...  neither did the Germans, nor the Swiss, nor the Canadians nor the Russians !
The pioneering Bullet 580 is a 235 ft. long and 65 ft in diameter airship that can lift payloads of 2,000 lbs up to 20,000 feet in the air.
It was inflated this week inside the Garret Coliseum in Alabama - one of the few facilities large enough to host the ship. The process took the developers at E-Green Technologies just over six hours.
The model 580 Bullet airship is 230 ft.  in length and covered with a thin material that is 10 times stronger than steel.
The $8,800,000  (£5.5million) craft can be flown remotely or with a crew. The company plan to build a fleet of hire vehicles (leased airships) that they will rent out for between $320,000 (£200,000) and $880,000 (£550,000) a month.
Chief Executive of E-Green Technologies, Mike Lawson, said: 'It's slow enough to be used for sightseeing, large enough to carry heavy cargo and enough volume of lifting capability to be flied (flown?!) at 20,000 feet unmanned. So you have a gift of all different technologies.'
Lift is provided by a system of seven bags filled with helium, while the inner hull is full of ambient air. Hydrogen was used in the 1920s and 1930s because helium was considered too expensive at the time and still is, the price point for helium being currently 12 times the cost of hydrogen; in addition, helium is scarce, expensive, and difficult to extract and purify . Hydrogen can be made by breaking down water into its constituent molecules of hydrogen and oxygen, both useful substances, by the use, of e.g., Concentrated Solar Power OR the hydrolysis of water using on-site generation of electricity by, e.g., wave or wind power. 

How the Bullet will look in the air. The blimp will run on ALGAE FUEL --- how difficult is that to obtain ??    ... how expensive ???  Are we missing something important in this supply chain ???
The airship will cruise at a speed of 35 m.p.h. , which will allow plenty of time for sightseeing for any passengers.
A BRIEF HISTORY OF AIRSHIPS, WHICH WE CERTAINLY NEED, AS THERE    AREN'T ENOUGH NEGATIVE HISTORIES PUBLISHED                                   (Yes, we're being sarcastic!)
In 1852 the French engineer Henri Giffard made the first  engine-powered flight in a steam-powered airship. A year later the American, Dr. Solomon Andrews, created the first lighter-than- air airship. He flew one over New York city in 1865. The first fully controllable airship flight was made in 1884. The 170 foot airship La France covered 5 miles in 23 minutes with an electric motor.
The first Zeppelin was launched in 1900. These had a rigid skeleton and passenger compartment.
During WW I the Germans, French and Italians operated airships but they were abandoned by 1917 due to unreliability. Britain developed the R33 and R34 rigid airships, which flew from 1919.
The R34 was the first to make an east-to-west Atlantic crossing.           

Another desperately-needed photograph of the Hindenburg disaster was inserted here and removed by Editor

In 1929 the LZ 127 Graf Zeppelin made the first round-the-world flight.  British journalist Grace Marguerite, Lady Hay Drummond-Hay was on board and became the first woman to circumnavigate the world by air.
Airships were poorly equipped to deal with adverse weather and crashes and fatalities were common. ... rather like writing a consumer review of a 2013 automobile by road testing 1914 Fords.
By the mid-1930s Germany was the only country pursuing airships. The Hindenburg disaster in 1937, which killed 37 people was the death knell.  Why doesn't this article mention the Navy blimps that flew bravely --- and apparently unsung ---  in all conditions to keep the menace of the Nazi U-boats from our Atlantic shores. Not one single merchant ship escorted by blimps was lost to German submarines . All this does not even mention the many search-and-rescue missions flown by Navy blimps bringing comfort and assistance to torpedoed sailors adrift in the ocean.
The U.S used airships during WW2 for military purposes but post-war they have mainly been restricted to advertising and Intelligence and reconnaissance missions too numerous to recite.
The payloads are carried inside the outer envelope of the balloon, which is only one sixteenth of an inch thick yet 10 times stronger than steel. It is made from a type of Kevlar, which is the tough material used to make bulletproof vests. Mr Lawson, said: 'If you hit a hard landing, the airship is just going to kind of bounce.'
Although the airship only has a top speed of 80 MPH it can take-off and land vertically. The craft is also able to hover over an area for up to a week at a time - something neither airplanes nor satellites nor helicopters can manage.
The craft could therefore keep a close watch on oil spills like the one in the Gulf of Mexico or monitor pirates off the coast of Somalia.
It could also serve as a near space satellite for broadcast communications, missile defense warnings, weather monitoring and geophysical surveys.
In fact its first mission will be to measure moisture content in soil. It is planned for later this year, will be a joint project of NASA and Old Dominion University. Mr. Lawson said he was confident that airships had a future in the 21st century, despite their bad press in the past.
Ed. Note : Only one airship had BAD PRESS, back in 1937; it seems to be the only tune that the Media orchestra can play. Only 36 casualties, and that appears to be the only voyage or mission that the Media remember; that one used hydrogen for the lifting gas , and flew into a strong electrical storm, which I believe they were warned about, but wanted to get down to the ground at Lakehurst, New Jersey, for the publicity and impatient passengers. Duh ! Think of all the impatient passengers that sleep on the floor of airline terminals during a snow storm. Personal observation .
His business acquired '21st Century Airships' in November 2009, which was one of the world's leading airship research and development companies.
The merged firm has already built and flown 14 prototypes, but the Bullet is their first commercial craft.
'Airships have undergone surprisingly little evolution throughout their more than 150-year history, and this is what makes our E-Green proprietary designs so desirable to government and commercial customers,' he said. I suppose that the reporter has performed little research into the many types of HYBRID designs .... NOR has she read her own description (above) of the newly developed materials of which airship envelopes are constructed, NOR has she heard of KORT nozzles, or cycloidal propellers, or ducted fans, or swivel mounts, or the remotely operated airplane drones flown over Afghanistan by pilots comfortably seated in Tampa, Florida.
'Our airships are radically different designs that move beyond the performance limitations of traditional blimps or zeppelins by combing advanced technology with simple construction and the ability to fuel with algae, protecting our environment.'
Algae is the latest biofuel exciting scientists. It draws carbon dioxide from the atmosphere when it grows and when the derived fuel is burned this same CO2 is released, making the fuel theoretically zero-carbon. Algae farms can also be created using brackish and waste water or, one could use HYDROGEN as fuel, feed it into a fuel cell (what's that?) and release nothing but water vapor into the air. Hydrogen is dangerous say Hindenburg-photograph-conscious perplexed readers ? We'll bet they drove to their office this morning in an automobile carrying a fuel tank of, say, 15 gallons of petroleum product --- one of the most explosive fuels available . OR perhaps they flew to their last vacation in a 747 , passenger jet, which flies at 35,000 feet (with no way of escape) with its fuel tank full of 48,445 U.S. gallons (183,380 liters) highly flammable jet fuel .
AMTRAK, anyone ?
The Bullet also has a Water Condensate Recovery System, which reduces the need for helium replenishment. Explanation needed here !!
The Bullet's first test flights are planned for this summer and the ship will be piloted by Captain Allan Judd who has been at the helm of smaller airships since 1986.
For those thousands of journalists who seem to have missed our compilation of civilian uses of airships the first time, here is our list, apparently not-yet-as-famous as Lady GAGA  :
Non-military Applications for LTA Airships for which Remotely Operated Airships Can Provide Safe & Suitable Service
1. Sporting event video coverage
2. Law enforcement: traffic, aerial views of traffic accidents;
3. Marine mammal population census, migration patterns
4. Design-and-Build surveys for planning & construction of bridges & roads
5. Marine biology --- spotting red tides in coastal waters; monitoring the health of coral reefs
6. Fire fighting --- first-on-scene situation assessment in high rise fires, inaccessible areas, or involving hazardous materials
7. News organizations --- parades, ceremonies, sporting events, and in  situations where danger to the news crew is possible (Think "Arab Spring" ! )
8. Radioactive and toxic waste sites --- photography, sampling, and survey without risk
9. Geology --- Oil field exploration; survey of volcanic processes and sampling of lava and ejecta from eruptions, without the hazard that recently took the life of two experienced volcanologists .
10. Federal & State Forest and Wildlife Services --- tree census; lumber poaching; game and fish poaching
11. Telecommunications --- surveying & designing fiber optic cable installations
12. Meteorological observations --- measuring wind speed, air pressure and temperature, dew point, & humidity at various altitudes above ground level 
13. Hoisting communications antennas during emergency situations
14. Fishing --- spotting big game fish for sport fishing; scouting for schools of food fish for purse seining; seining schools of fish & invertebrates visible from the air, for sale as bait to both commercial and sports fishermen, responsibly increasing the harvest with a minimum of wasteful by-catch.
15. Monitoring railways, pipelines, and power lines --- a constant and ever-present safety requirement --- that can prove very difficult in overgrown areas, or results in expensive and wasteful ground-clearing  .
16. Monitoring air pollutants for measuring air quality standards .
17. Agriculture --- Precision agriculture techniques using remote sensing technology to monitor crop moisture content AND to perform no-harm seeding from the air, in which the soil does not get compacted by heavy tractors and therefore remains friable as a good seed bed with maximum germination and a larger harvestable crop. Aaaaah-h-h, at last ! Here is the one Application they seem to have heard about
18. Archaeological site mapping; correlating aerial photographs with ground level excavations and discoveries
19. Commercial aerial photography for tourist and visitors’ bureaus, yacht brokers, school programs; realtors and real estate developers;
20. "Green" non-disruptive exploration of ecologically sensitive biospheres, such as rain forests and forest canopies sheltering endangered species
21.  Lifting transmitters & receivers into the sky for maximum range.
22. Long term recording in place by meteorological instruments --             anemometers, humidity meters, thermometers, etc.
23. Air sampling for pollutants, particulates, insects, and pollen.
24. Acoustic sensors for detection of intruders, without interference by the noise of internal combustion engines
25. Detection of mines & other explosive devices [especially relevant for civilian use, detection of unexploded abandoned mines, a major cause of death and crippling injuries to children in former war zones ]
26. Thermal imaging applications                                                                                                                                                                                                                        27. Crowd control and detection devices by law enforcement agencies
... and many more, too numerous to list .

Sadly, the length, complexity, and copyright protection of articles on the manufacture of biofuels derived from algae preclude our reprinting them here . This discussion of airships does not even touch on the cost, difficulty, and environmental effects of manufacturing algae as biofuel. As our math professor used to say just before dismissing the class, "I leave the solution of that problem to the class as homework".

OUR IMPRESSION : The HYDRAIL Conference has been principally conceived and executed by Stan Thompson, of Mooresville, North Carolina, a dedicated supporter of the use of hydrogen in unique and environmentally sound ways. He has built a world-wide constituency solely on the basis of his energy, the soundness of his views, and the strength of his commitment.

What IS a hydrogen-powered locomotive (HYDRAIL) ... especially, a 10.25 inch gauge miniature railway locomotive ? We outlined its application to Mega-Model miniature railways in bold-face type in the lead paragraph above to call attention to this unusual application of an important new technology.

First of all .... HYDRAIL is the fascinating new concept which utilizes a fuel cell, mounted in a locomotive --- and now other modalities with a Green power requirement (it is already being installed in many new ship engine rooms because of recent Draconian restrictions by European countries on carbon emissions) --- to generate electricity for traction motors.

Second of all, "miniature railway" is the Term of Art applied to mega-scale models with a gauge greater than 7½" and 7¼", especially those operating in Great Britain . Model railways in a scale of 1 : 5.5 (10.25" gauge) are popular in England, where that scale is utilized in a substantial percentage of passenger-hauling hobby-and-leisure layouts. Our educated guess is that this large scale was chosen for this installation because it provides a good deal of room for mounting the fuel cell.

Third of all ... the fuel cell : a newly developed device which is fueled by hydrogen stored on board in a high-compression cylinder, and fed as fuel to the cell. The output of the process is electricity, used to power traction motors in the locomotive, and ... Ta-dah ! it emits only water vapor as exhaust ! This solves four major issues :

1. the diesel particulate problem (a serious health threat)

2. the carbon cycle problem : emission of carbon dioxide by internal combustion engines and its possible effect on climate change

3. geo-political problems engendered by the importation of foreign oil (and the use of domestic oil, also, as the two are essentially commingled in the logistics process, a fact often ignored by those with personal supply chain agendas), and

4. the diesel engine noise problem,

all at one swell foop .

Fuel cells offer a nifty energy solution, but one that is being accepted and adopted only very slowly by the tradition-bound railroad industry.

We sincerely hope that news of the possibilities inherent in this technology are spread among the NGO's (non-governmental organizations --- essentially non-profit organizations), Metropolitan Planning Organizations (MPO's) , and political decision-makers, as well as among the usual suspects crowd of technocrats and engineers.

FLASH ! We just (mid-afternoon, 1 October 2012) received a news bulletin that contenders in the famous Albuquerque LTA balloon race may be using hydrogen as a lifting gas for the first time, because of a world-wide shortage of helium, reflected in both availability and price. An amount needed to fill the average balloon with helium now costs $12,000; the cost to fill the same balloon with hydrogen is only $1,000, a very significant difference. If that is an accurate reflection of the situation, it will, in all likelihood, also be reflected in planning and activities for LTA dirigible airships . It will be another good reason for serious exploration of the HYDROGEN ECONOMY !

DEDICATED READERS OF THIS BLOG WILL NOTE THAT HYDROGEN HAS BECOME THE LOGICAL LINK OF BOTH SPECIAL INTERESTS. OUR AIRSHIP UNIVERSE Blog and our ELECTRIC RAILWAYS NETWORK find an unusual but signifcant convergence in the use of hydrogen to achieve their goals. We had no way of knowing that would happen, but are delighted to note its occurrence.
