… And very very small. While large submarines and spacecrafts are used for energy by at least 50 years without recharge, this technology has been off limits to commercial use, for obvious reasons.

Now, in the Univerdidad of Missouri have developed a nuclear battery the size of 1 cent. The idea behind is to develop more durable sources of energy meters and sensors for scientists, especially those who are at the mercy of nature and where recharge is not as easy as plugging into an outlet.

Professor Jae Kown, director of this project led to an innovation in this regard, not so much the size but by the semiconductor used. Instead of using solid state one, use a liquid. The most critical in the use of a radioactive battery is that the time to take power, some of this may damage the rigid structure of the semiconductor. By using a liquid, they can solve this problem. At the end of this project is expected to have a battery as thin as a human hair.

Leaving aside the potential danger to health, to succeed these inventions, Can we talk about the future of batteries year? “Phones with batteries that last years? What about the waste, as would be handled? If the dangers are greater than the benefits, better look for alternatives. Like the sun, for example.
