$1M Challenge for mini-inverters for cars and more

googlechalleng2With the catchy phrases “think shrink”, “smaller is bigger” and  “min it to win it”, the Little Box Challenge, sponsored by Google and IEEE will pay a one million dollars to the company or entity that builds and designs a kW-scale inverter with the highest density of at least 50 watts per cubic inch.

Inverters are the boxes that convert direct current from sources such as solar panels or batteries and turns it into alternating current for use in homes, businesses or cars.
