DHEnterprises has been working on what it calls the Revolutionary Wind Tower, a 300-m tall tower with deflectors at the top to redirect high-speed wind (50 mph and more) into generators. The RWT has been in development for three years and developer Daniel Hoose says patents are in hand.
The RWT has a high capacity of up to 396 MW per tower and a cost advantage such that it needs no wind subsides. It’s priced at $1 million/MW capacity.
He expects one tower to generate about 390 MW and says he has developed charts and graphs showing how the tower affects the ambient wind and the intake-to-outtake wind-speed ratios for various intake sizes.
The turbines will withstand high speed winds. Within their rotor space, the ducting can generate wind velocities carrying hundreds of thousands watts per square meter. Equations that show energy proportional to the cube of the wind speed make this system worth developing, says Hoose.
The tower design calls for extensive use of composite concrete that is strong, light, and flexible. Outside panels made of these materials should let the towers last for 100 years. The base, up to 400-ft. high, will be made of standard concrete.
Like conventional turbines, the RWT will generate no emissions. It will also have no braking system and no external rotating blades or blade flicker. Rotors will be recessed 145 ft. into fiberglass intakes. And because the rotors are encased in a sound insulated housing, they will generate no noise.
RWT technicians will use an elevator so there are no ladders to climb. Most all maintenance will be done from the inside. One RWT unit can replace a whole wind project, says Hoose, so there is no need to build huge wind fields.
A state the size of Vermont can get 100% of its electrical needs from just five large towers. Furthermore, the inventor envisions no need to worry about energy storage or power fluctuations, because the RWT’s will mostly make hydrogen, and that will allow starting the hydrogen economy.
The RWT is breakthrough technology, says the inventor, that can jump start the hydrogen economy, begin to retire fossil fuels, and start to clean the environment. Even oil companies will encourage such development because it will be cheaper and more profitable than drilling for oil. The developer expects the RWT’s to produce power at 6 to 7 cents/kWh.
What’s more, says Hoose, a 100-year life span could show the RWT a better business investment, four times that of the competition. In fact, says the developer, each 396-MW tower can produce an average of 1.6 million MWh/yr. The base of the tower could also serve as a cave for bats and other bird species.
The company is looking for investors.

The Revolution Wind Tower is much more than a “nice drawing”. What This tower does is not direct wind, it channels and increases velocity of the wind, further more the wind the tower does not try to stop the wind, over 40% of the winds energy passes right through. For someone to look at this a think there is no solution to a problem does not give much credit to the field of engineering and is of course, short sighted.

Its a nice drawing, but unfortunately air does not like to be directed. If you put up a wind brake the wind simply goes around it.
There is a limit to the energy you can draw out of one spot of air. Buy some GE stock next time.
