Solar Airplane and Ocean Wave Power Generation
Solar Flight, Extra Lifestyle Efficiency & Ocean Power
It was a great accomplishment when the Zephyr solar plane spent over 2 weeks in the air. Some even dubbed it the “eternal plane”. But it looks like the Zephyr is about to get some serious competition: Boeing just signed an $89 million contract with the U.S. Defense Advanced Research Projects Agency (DARPA) for the development of a solar airplane that will be in a league of its own. Read on for more details.
Boeing has a highly reliable solar-electric design that will meet the challenge in order to perform persistent communications, intelligence, surveillance and reconnaissance missions from altitudes above 60,000 feet. The solar airplane will have highly efficient electric motors and propellers and a high-aspect-ratio, 400-foot wing for increased solar power and aerodynamic performance. These solar airplanes may be the new satellites, soring 60,000 feet above the earth for years at a time relying on solar powered electric engines.
Box House Highlights Features of the Future:
The house, designed by renowned Swedish architect Gert Windgård, is not designated a passive house per se, but is said to maximize its own electricity production through a complete front facade of solar panels (solar water heating and solar electric) and minimize heat loss through a double-doored entry, built-out window boxes and fantastic insulation. (The U-rating in the windows is 0.8.)
The HVAC system recycles air warmth – there is no furnace in the house so appliances, body heat and sub floor heating do the extra work to keep the house warm in winter. The house, as designed, is said to be approximately “80 percent efficient,” and the family will get their remaining required electricity from Vattenfall’s wind and hydro power. Wow, maybe a family of four does not really need 4,000 square feet, 3 baths and a three car garage.
Ocean Waves Generate Electricity:
What is it about Oregon State U? We just wrote about their super glue from mussels and now they top that with a ” permanent magnet linear generator buoy. An electric coil surrounds a magnetic shaft inside the buoy, and while coil is secured directly to the buoy, the magnetic shaft is anchored to the sea floor. When waves cause the coil to move up and down relative to the fixed magnetic shaft, voltage is induced and electricity is generated.” 200 of them could power downtown Portland, Oregon. Oregon State likes oceans and they are proving it. Buoys would look better than great big wind generators, besides, waves always move , but wind does not always blow.
Plug Her in and Fill’er Up:
Yes. Production of plug-in electric vehicles will grow to record levels over the next several years with the roll-out of diverse PEV models by many different major auto manufacturers, including Ford, GM, Mitsubishi, Nissan and Toyota. GM alone expects to produce 80,000 Chevy Volts by 2011 and 200,000 by 2014. Nissan is planning to produce 25,000 Leafs by 2011. Just the volume figures from these two manufacturers represent a highly accelerated market curve – more than twice the initial five-year sales rate of the entire hybrid fleet.I like it, smash the excelerator and get a pleasant whirling sound. High school students leaving the parking lot won’t be the same.
Hi, thanks for stopping by Detect Energy and reading Power Notes. Come back soon, but I won’t be leaving the lights on for you…Don Ames
