The Recharging Road

Here is a great article out of the US, where MIT researchers are working with magnetic resonance coupling to try to make feasible roads that recharge electric cars. This means you would never have to stop to recharge or get fuel again, assuming you staying on road.

230% efficient LED bulbs

It has been a long time indeed.

There was quite a fascinating article today about how scientists have created 230% efficient LED bulbs. Now, that's not violating any principles of energy conversion, merely outputting more energy in the form of light than is being input in the form of electrical potential. The extra energy comes from lattice vibrations in the system - which means the device is actually converting ambient temperature/heat into light!

Some thermodynamics calculations are in order. However it's MIT, so I'm gonna believe them. It's also a south Indian PI, so I'll try to believe harder. A slightly technical synopsis is here.Link
