MIT Researchers’ New Device Generates Electricity From Air

Mila Luleva — Thu, 24 Jul 2014 07:09:02 +0000

Just because solar and wind power are making an incredible progress, it does not mean that the other renewable energy sources should be neglected and researchers should stop looking for alternative means for energy generation. This is why, researchers from MIT took on the task to see exactly how much energy they can produce from condensation. […]

Before going into the details of this invention it would be worthwhile to have an idea of how any generator, even in theory, could be capable of producing a self-sustaining current. This has been clearly explained by Walter M. Elsasser in a Scientific American article (May 1958) titled "The Earth as a Dynamo."

Core77.com’s “Greener Gadgets Competition” shows up a system invented by Alexander Parker, that could power your laptop, cellphone, or other device that has buttons as an input, to an extent that could replace your battery (for example, if you write a lot, you could write more). Assume that if for each character in a text […]

Tesla’s Unipolar Dynamo working principles

Ovidiu Sandru — Sat, 02 Feb 2008 18:13:07 +0000

Tesla’s design varied from that of Faraday in two major ways. First, he used a magnet that was bigger in diameter than the disk so that the magnet completely covered the disk. Second, he divided the disk into sections with spiral curves radiating out from the center to the outside edge. In the Faraday unipolar […]
