Nuclear power, bastard child of the Cold War is just fine until it’s not, and when its not the problem can quickly escalate beyond the human ability to deal with it — Fukushima tells that tale very convincingly. And then there is the issue of the nuclear waste which no one knows what to do with and which, in theory, must be maintained in a stable state for, well no one is really sure, but potentially 200,000 years. Since human recorded history only dates back to the Fourth Millennium BCE, roughly 6,000 years, you can see the problem.
An electric generator that runs itself, because it does not oppose magnetic resistance to the motion of the rotor… a very interesting development out of India.
A Reactionless AC Synchronous Generator has been invented by Paramahamsa Tewari, electrical engineer and former Executive Director of Nuclear Power Corporation of India. His background includes engineering project management for construction of nuclear power stations. The efficiency of models he has built, which have also been independently built and tested, is as high as 250%.
Thermoacoustics – there seems to be a lot going on in the field of the sound and heat (and magnetics) combination.
So heat, sound and magnetic fields have been shown to influence each other. This adds to another recent post about students experimentally putting out fires with sound waves…
Experiment reveals new mysterious properties of sound waves
COLUMBUS, Ohio—Researchers at The Ohio State University have discovered how to control heat with a magnetic field. In the March 23 issue of the journal Nature Materials, they describe how a magnetic field roughly the size of a medical MRI reduced the amount of heat flowing through a semiconductor by 12 percent. The study is the first ever to prove that acoustic phonons—the elemental particles that transmit both heat and sound—have magnetic properties.
