Google, along with Institute of Electrical and Electronic Engineers (IEEE), has started a ‘Little Box Challenge’ to design and build a kW-scale power inverter, a device used to convert renewable energy, including solar and wind, before transforming it into suitable current for home and vehicles.
The challenge is that the new device has to be of the size of a small laptop, roughly 1/10th of the current size.
“We are looking for someone to build a kW-scale inverter with a power density greater than 50W per cubic inch. Do it best and we will give you a million bucks,” Google said in a blogpost.
Google believes that this will help “change the future of electricity”.
“We believe that inverters will become increasingly important to our economy and environment as solar PV, batteries, and similar power sources continue their rapid growth,” Google said.
