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.

How is this any different than wanting to use rare resources like lithium and other rare earth metals to power hundreds of millions of cars?


#1. Rare Earth Metals are not required by a Lithium Electric Car. The NiMH battery type currently used in a Prius, does indeed need significant rare earth metals. Some types of electric motors do use Rare Earth Metals (Including the current Chevy Volt motor), but others do not.

The Model S, a beautiful, practical, albiet still too expensive model, uses almost no rare earth metals

#2. Lithium is hardly rare either. The reserves for the "easy" to get Lithium Carbonate Salts is around 13 million tonnes. Enough for more than 1 billion electric cars.

Lithium batteries are nearly 100% recyclable

#3. Electric cars wouldn't need to use a specific battery chemisty. Lithium batteries are significantly better than NiMH, Lead Acid, and other types current available for a variety of applications.... but better batteries could be invented in the future.

In comparison, these balloons use

#1 A gas already in short supply (apparently)
#2 A gas that can't be recycled
#3 The lightest possible gas
