These days, if you’re an engineer, inventor or just a tinkerer with a garage, you don’t have to look far for a juicy opportunity: there are cash prize challenges dedicated to landing on the moon, building a self-driving car,cleaning the oceans, or inventing an extra-clever robot. Today, together with the IEEE, we’re adding one more: shrinking a big box into a little box.



Seriously.



Of course, there’s more to it than that. Especially when the big box is a power inverter, a picnic cooler-sized device used to convert the energy that comes from solar, electric vehicles & wind (DC power) into something you can use in your home (AC power). We want to shrink it down to the size of a small laptop, roughly 1/10th of its current size. Put a little more technically, we’re looking for someone to build a kW-scale inverter with a power density greater than 50W per cubic inch. Do it best and we’ll give you a million bucks.
