  • Controlled Tornadoes Create Renewable Energy

    Tornadoes may be destructive, but even funnel clouds have a silver lining. Inspired by the process that creates natural twisters, electrical engineer Louis Michaud of Canada’s AVEtec Energy Corp. designed a nonpolluting source of swirling power he calls the Atmospheric Vortex Engine. The device can spin waste heat from power plants into usable energy.

    Instead of directing excess heat into conventional cooling towers that simply disperse it into the air, power plants could usher the heat into the hollow, open-topped tower of a vortex engine. A heat exchanger outside the tower transfers the extra heat (piped in as warm water) to ambient air.

    When this warmed air is directed into the tower at an angle, it encounters cooler air and produces a circular current. This current funnels air upward into a controlled twister whose low-pressure center draws more air into the tower, turning turbines at its base. These turbines drive a generator much like a wind turbine does, except, as Michaud says, “You’ve got more oomph to push it with.”

    Michaud has already demonstrated working models of the engine up to 15 feet across, but the real deal would measure 300 feet wide and half as tall, capable of producing tamed twisters that stretch nine miles high. When hooked up to the average 500-megawatt natural-gas or coal power plant, the vortex engine could produce an extra 200 megawatts of energy just by putting the excess heat to use.

    At a cost of less than 3 cents per kilowa...

    In a June press release issued by the U.S. Department of the Interior, new Interior Secretary Sally Jewel announced the Obama administration’s latest steps in its “all-of-the-above” energy strategy. The release announced the approval of three renewable energy projects and a crucial first step in development of the massive potential of U.S. offshore wind power.

    The Department of Energy (DOE) generally funds development of new renewable energy technologies. However, the Department of the Interior (DOI) may be a significantly bigger player in the expansion of renewable energy production by opening the country’s public lands and coastal waters to competitive proposals for responsible domestic energy production. In fact, since 2009, the DOI has approved a combined 45 utility-scale solar facilities, wind farms and geothermal plants that will ultimately provide enough electricity to power 4.4 million homes.

    These latest DOI approvals include solar farms located in Arizona and Nevada and a geothermal power plant in Nevada. The solar energy projects are Boulder Solar Power’s Midland Solar Project and SolarReserve’s Quartzsite Solar Project. TerraGen Power will build the New York Canyon Geothermal project.

    Midland Solar Project

    Proposed by Boulder Solar Power, LLC, the Midland Solar Project will be built on private land southwest of Boulder City, Arizona. However, electricity from the 350-megawatt photovoltaic facility will pass acr...
