ApplicationRegister to compete for $1 million and help change the future of electricity.

The goal: design and build a kW-scale inverter with the highest power density (at least 50 Watts per cubic inch).

Inverters are the essential boxes that take direct current from devices such as solar panels and batteries and turn it into alternating current for use in homes, businesses, and cars.

The problem is household inverters are too big—roughly the size of a picnic cooler. Making them smaller would enable more solar-powered homes, more efficient distributed electrical grids, and could help bring electricity to the most remote parts of the planet.

That’s where you come in: figure out how to shrink an inverter down to something smaller than a small laptop (a reduction of > 10× in volume) and smaller than everyone else, and you will win a million dollars (and help revolutionize electricity for the next century).

DEADLINE: September 20,2014; applicants contemplating competing in the prize must register their team by the registration
