People rightfully dislike wireless signals being transmitted from the person behind the wheel when they text while drive, but there are times when a car's wireless signals can be good news. Researchers at the Massachusetts Institute of Technology (MIT) have found a way to use wireless signals under the hood to help cut pollution from heavy-duty vehicles such as diesel-powered trucks. That's something we can get behind.
For electric items that are too mobile to be connected by wire, like – to pull a completely random example out of the air – a car traveling down the highway, the idea of wireless power transmission has a lot of appeal. Several different schemes have been considered, including magnetic induction, microwaves, or even lasers. Now, researchers in Japan are examining a system that would use a radio frequency signal to transmit power.
Salt water as fuel? Not exactly, but kinda. John Kanzius discovered that by focusing certain radio-frequencies on a test tube of salt water, he could ignite the contents, which would them become hot enough to melt the test tube. The process has been independently verified by Rustum Roy, a Penn State University chemist. According to Roy, what is actually happening is the hydrogen is being separated from the salt water and ignited. As long as the water is bombarded with the radio-frequency, it con
