Science ABC: the eddy currents, and the coolest video you’ll see today

Eddy currents are electrical phenomena that take place when a conductor is exposed to an oscilation of the magnetic field due to the relative motion of the field source and conductor; rewind. You have a conductor, say a copper tube, and a magnet. One moves relative to the other and you’ve got current (basically a [...]

Scientists create the first molecular transistor

Researchers from Yale University succeeded in what seemed to be an impossible task: they’ve created a transistor from a single molecule. In case you don’t know, a transistor is a “semiconductor device commonly used to amplify or switch electronic signals” (via wikipedia). The team showed that using a single benzene molecule attached to gold contacts is [...]

Electricity from trees

Researchers have figured out a way to ‘plug’ into electrical power generated by trees. It’s a well known fact for years that plants can conduct electricity (humans can too, take care kids), and now scientists from MIT found out just how much they can pack up: 200 millivolts of electrical power (=0.2 volts). The lemon and [...]

Bacteria To Generate Electricity

Researchers are searching everyday for options which could bring an ending to the energy issue or at least delay it for an undefinite time and bacteria researching has developed a lot so it would only seem sensible to bring those two together. The point would be well to obtain a bacteria which generates electricity. Researchers at [...]
