steam powered generator 2 kVa
My dad built this, a 8kVa is coming soon! Harry shows off the WHE at the Steam Automobile Club of America meet 2010. Cyclone Power Technologies Waste Heat Engine (WHE, pronounced “we”) recaptures heat from external sources to create steam which powers the engine. The WHE models are designed to run a grid-tied or primary […]

Otherpower Steam Generator
Here’s another video of our steam powered back up generator on a snowy day producing 2KW. The fuel is lodge pole pine. The video shows the engine, and then a shot at the wall shows the 3 phase rectifer we use to rectify the 3 phase AC into DC for battery charging. I have a […]
Chill out desk: Nuclear fusion & fission
Nuclear energy can provide the world with much of its electricity needs but many people are worried about it. Scientist Joe Kaplinsky explains what nuclear energy is and answers the four major objections to it: radioactive waste; nuclear accidents; nuclear weapons and the high expense. He concludes that we should chill out about the risks […]

What would happen if we used high energy neutrons in fission reactors?
Question by Chris: What would happen if we used high energy neutrons in fission reactors? I’m not %100 sure about this but isn’t nuclear waste created when the neutrons that are sustaining the fission reaction get absorbed by the fission fuel instead of smashing them apart? If so then couldn’t high energy neutrons produced by […]

Bhutan hopes to cash in on hydro-electric power – 30 Mar 08
Bhutan, the world’s newest democracy, is hoping to boost its economic prospects by harnessing its major natural resource – water. The Tala hydro-electric dam in southern Bhutan is already making 5 million a year by exporting electricity to India. As Tony Birtley reports, another six big hydro-electric projects are in the pipeline.
Why do some wind turbines turn while others remain stationary?
Question by Sarah: Why do some wind turbines turn while others remain stationary? When driving through Minnesota, my mother and I often wonder why it is some wind turbines will be merrily spinning away, while others are much slower or even stationary. Why is this? Are perhaps some of the turbines “turned off”, so to […]
