Bacteria powered batteries use the chemical energy generated by bacteria, and convert it into electrical energy using a relatively simple mechanism. Like most batteries, a bacteria powered battery has an anode (the negative end) and a cathode (the positive end). In addition to the anode and cathode, a bacteria powered battery also has a membrane capable of filtering electrons (anions) and protons (cations) produced during the chemical breakdown of substances by bacteria.

Air powered cars

Have you been to the gas station this week? Considering that we live in a very mobile society, it's probably safe to assume that you have. While pumping gas, you've undoubtedly noticed how much the price of gas has soared in recent years. Gasoline which has been the main source of fuel for the history of cars, is becoming more and more expensive and impractical (especially from an environmental standpoint). These factors are leading car manufacturers to develop cars fueled by alter ....etc

Steam Powered Robots
Abstract:
Steam may be the answer to a problem that has always dogged robotics: how to feed a robot enough energy to do useful work But steam doesnâ„¢t mean old fashioned boilers, water supply, and burning fuel. Instead this technique makes use of hydrogen peroxide to generate steam.
A major barrier holding back humanoid robots is the lack of decent motors. They also need a power supply that doesnâ„¢t take all of the robotâ„¢s energy just to move i ....etc

The quantum of energy in the universe is constant. Neither can man create energy nor can he destroy it. All that he can do is to discover new source of energy that the natural has provided and make it usable for his needs by new and more efficient ways of conversion. A solar powered refrigerator using an intermittent ammonia-water absorption system as refrigeration in remote areas where electrical energy is not available is described in this paper. In my present paper I have made an analysis of feasibility of utilization of solar energy in the ....etc

The focus of the research has been on producing tiny batteries for powering MEMS and which, in theory, could last thousands of years. While radioisotope batteries have previously been used in spacecraft, the new batteries are much smaller and utilize a liquid semiconductor as opposed to traditional solid state devices used in nuclear batteries. The battery's output is 16.2nW.The research has been undertaken by Prof Jae Kwon and J David Robertson from the University of Missouri. Robertson said: The hard part of using radioactive decay is th ....etc
