( -- Wind turbines that float hundreds of feet above the ground or sea and are deployable in 24 hours are the focus of the "Aerostat Platform for Rapid Deployment Airborne Wind Turbine" project that is the winner of the 2011 ConocoPhillips Energy Prize, awarded by ConocoPhillips and Penn State.

The ConocoPhillips Energy Prize recognizes new ideas and original, feasible solutions in three areas that can help improve the way the U.S. develops and uses energy: developing , improving energy efficiency and combating climate change.

Ben Glass, CEO of Altaeros Energies, inventor of the Altaeros Airborne Wind Turbine and Adam Rein, co-founder, Altaeros Energies are developing wind turbines that are stationary blimps, which take advantage of the more consistent and higher speed winds at altitude. These floating can be used in remote areas where they arrive in a box and, once inflated with helium, rise into the air, tethered by a conducting cable. The turbines can supply 100 kilowatts of electrical power without using fossil fuels or producing any .

While initially the company plans to sell these elevated turbines for remote uses such as military applications, emergency power and other remote installations, eventually they will form the basis of offshore, deep-water floating high above the waves.

Aerostats, like these airborne turbines, are currently used in a variety of locations and contexts and can remain in the air for up to three months without replacing helium. The rules and regulations for deploying aerostats already exist and these inflatables have a proven track record.

The first runner up was Jason Aramburu, founder and CEO of re:char and his team. Re:char manufactures small kilns to locally manufactured biochar on farms in Kenya. Biochar, manufactured from waste such as and other plant materials, is a charcoal-like material that can be made into briquettes, but can also be added to soils to improve their productivity. Selling the briquettes can earn local farmers money, but using it in the soil improves crops far more than simply selling the biochar.

The second runner up was Mark Mascal, professor of chemistry, University of California, Davis, for "Conversion of Plant Carbohydrates Into a New Generation of Biofuels and Substitutes for Petroleum Products" who uses inexpensive solvents and low temperature to convert cellulose and hemicellulose into furans, which can become the basis for biofuels, drugs and plastics.

The five finalists included Jack C. Swearengen, emeritus professor and founding director of engineering programs, Washington State University, Vancouver, for "Carbon-Free Ammonia for Agriculture," a project that uses nitrogen from the air and hydrogen from water to create ammonia without producing carbon dioxide.

Also among the five finalists was Li Song, assistant professor, School of Aerospace and Mechanical Engineering, University of Oklahoma and Gang Wang, assistant professor, Civil and Architectural Engineering, TAMUK, who work on automated energy monitoring for commercial buildings.

Each of the five finalists received an award of $25,000 to further the development of their concept. The winner received an additional $100,000; the first and second runners-up received an additional $50,000 and $25,000, respectively

In 2010, ConocoPhillips and Penn State awarded the Energy Prize to Matthew Orosz and team STG for a solar generator that could bring electric power to remote areas around the world. The "Small Scale Solar Organic Rankine Cycle for Rural Cogeneration" provides electricity and hot water for remote, off-the-grid health clinics and schools.

Could they add thin film solar to the outside ? Also, why use 3 blades as opposed to a screw ?

once inflated with helium, rise into the air

They'd better consider using hydrogen instead of helium because before long they won't have helium to use for applications like these.

I agree. I would say they should atleast use hyrdrogen over the ocean where there would be no fire hazard. But i think the inflatable wind turbine being developed by Maggen Power Inc.( looks more promising.

Using hydrogen would have some advantages, like onsite production and better lift. Other than its flammability, leakage is a serious problem.

I like their designs and they may show promise but they don't address some real issues. I'm working on my second prototype that addresses the three main problems that I see in floating wind generators (FWAT) Counter torque of the generator, instability of the current designs (uncontrolled pitch and yaw in variable winds)and last the generator. Hopefully I'll have the project completed by early spring. (PS: you are correct in helium vs hydrogen production).

Exactly, and more of a problem than is typically acknowledged. Deploy such a thing on mass scales, and just like with any other "hydrogen economy" proposal the net quantities of leaked hydrogen -- rising to the top of the stratosphere, and there reacting with ozone -- will ensure that the ozone layer is history not just over Antarctica in the dead of winter, but over the entire planet's surface year-round.

This technology (airborne wind turbine) is fantastic, but there ARE a few things to iron out, such as: what material would they use for the tether to keep it in control and, how would they prevent it from moving in an arc and possibly getting into the way of an aircraft. . .including helicopters. It would ONLY be safe to keep a line of them over the ocean. Obviously, over land would be too dangerous. Also, how far from the line of turbines would the power plant be built?
