Alternative power source might be a good idea if it wasn't for record helium shortages

Altaeros Energies is taking greenwashing to a new height with the debut of its bulbous helium filled Airborne Wind Turbine (AWT).  The company looks to replace one depletable resource that comes out of the ground (oil/coal) with another even scarcer resource that comes out of the ground (helium).

The company writes:

The company recently completed testing of a 35-foot scale prototype of the Altaeros Airborne Wind Turbine (AWT) at the Loring Commerce Center in Limestone, Maine. The prototype, fabricated in partnership with Doyle Sailmakers of Salem, Massachusetts, achieved several key milestones. The AWT climbed up 350 feet high, produced power at altitude, and landed in an automated cycle. In addition, the prototype lifted the top-selling Southwest Skystream turbine to produce over twice the power at high altitude than generated at conventional tower height. The turbine was successfully transported and deployed into the air from a towable docking trailer.

Altaeros is developing its first product to reduce energy costs by up to 65 percent by harnessing the stronger winds found over 1,000 feet high and reducing installation time from weeks to days. In addition, it is designed to have virtually no environmental or noise impact and to require minimal maintenance. The Altaeros AWT will displace expensive fuel used to power diesel generators at remote industrial, military, and village sites. In the long term, Altaeros plans to scale up the technology to reduce costs in the offshore wind market.

A glowing view by Inhabitat paints Altaeros as some sort of jedi messiahs, writing, "In an effort to harness strong high-altitude winds, the company Altaeros Energies has developed a floating wind turbine that’s a cross between a traditional windmill and a blimp. After some successful tests, the Altaeros team is confident that this new levitating wind turbine will be a viable clean energy option for remote villages and military sites."

Altaeros founder, CEO, and AWT inventor Ben Glass brags of his "levitating" turbines, "For decades, wind turbines have required cranes and huge towers to lift a few hundred feet off the ground where winds can be slow and gusty.  We are excited to demonstrate that modern inflatable materials can lift wind turbines into more powerful winds almost everywhere—with a platform that is cost competitive and easy to setup from a shipping container."

The platform is built upon helium -- a scarce natural resource mined out of the ground.

Helium supplies are running so low that it is estimated it may run out within 30 years.  Aside from the environmental impact of drilling to extract helium from gas pockets in the Earth's crust, there's the issue that much of the most critical physics and chemistry research relies on helium.  The helium crunch has literally led to millions of dollars in lost productivity at research centers such as CERN's Large Hadron Collider.

But no worries.  Let's take the last of our helium and float it up in big blimps with wind turbines attached.  Clearly this deserves some sort of prize for intellectual excellence.

Use hydrogen.

Problem solved

Hydrogen in a party balloon sure would make it more fun. A fireball instead of just a pop when you get it to close to the cake!

Hydrogen can't be used for everything. Liquid helium is used to cool the superconductive magnet in my lab. That's a temperature around 4 Kelvin, with a liquid nitrogen sheath to keep the helium from catastrophically boiling. But even if it did, the worst that would happen is someone could get knocked unconscious until the emergency fans turned on to drag oxygen back into the room.

Liquid hydrogen on the other hand is too hot to keep the magnet superconducting, with a temperature of 20 Kelvin. It is also basically rocket fuel, and so reactive (all it needs is 4% air, yes, AIR not pure oxygen, and a very small energy source to ignite) it cannot be used with this machine unless we wish to explode the entire biology department sky high, and that is not a joke.

Liquid hydrogen has to be handled very differently, and all air must be constantly kept away from it--something absolutely impossible for our equipment and experiments. And again, this is ignoring the fact liquid hydrogen is 10x hotter than liquid helium, and completely useless for what we do in the first place.

For many, many research applications, helium is irreplaceable. And we are indeed running out, which bodes ill for the research of my lab and others like it. That's why people like we see in this article need to switch to hydrogen gas, as you say, and stop wasting our precious helium.

Last time I checked they didn't inflate balloons with liquid helium or liquid hydrogen. So I ask, what exactly is the point of your comment? Hydrogen is basically an infinite resource and needs to be utilized where it is deemed appropriate.

In an unmanned vehicle flying 1000 feet in the air around uncongested areas seems very appropriate to me. Plus, from looking at the picture, the actual turbine is so far away from the blimp that any leak would almost instantly be dissipated into the atmosphere. i.e. harmless. It would react instantly with atmospheric oxygen to form water.

Yes, the reaction produces heat, but there would not be enough hydrogen leaking out of this blimp to spontaneously combust.

What you said makes sense except for this. It takes gaseous helium to make liquid helium, so in reality they are filling the balloons with the exact same thing.

In our lab, we have to use Helium because the EPA will not update their methods for chemical analysis to include the ability to switch from helium to hydrogen in the chromatographs. What is really sad is hydrogen works better but when used with a mass spectrometer it gives a slightly different mass signature, which can be standardized to compensate for yet the EPA forces us to use the mass signature that can only come from using helium. We could save thousands of dollars a year if we could switch from helium to hydrogen which could reduce the cost of testing everything from safe drinking water to hazardous waste, if only EPA would get off their duffs and ok the changes.

They did the same thing with freon, we had tests that required freon as a solvent, then they outlawed freon before they found a replacement in the testing procedures. We were spending $500 for freon on what we had been charging $15 per test before the ban. Plus the EPA would not forgo the requirement for that test so we had waste water plants and drinking water plants that had to bear the extra cost for a year until EPA approved hexane as a replacement.

Have you bought R-22 lately? It's hitting $100/per pound! Thanks Obama and the EPA! I love paying 4 times more than before to get my AC serviced.

Apply all those same bureaucratic problems to health care, and every other program, and.. its obvious to same why "less is more" seems a good idea to some. Other people though see no problem with such bottlenecks and inherent inefficiencies.

Indeed, you illustrate an absolutely perfect example of why central planners can NEVER possibly know how individual actors should go about their business better than those individuals do themselves.
