Google Challenge Results In Astoundingly Efficient Inverters

AmiMoJo writes: A few summers ago, Google and IEEE announced a one million dollar prize to build the most efficient and compact DC to AC inverter. It was called the Little Box Challenge, with the goal of a 2kW inverter with a power density greater than 50 Watts per cubic inch. Typical solar inverters have a density of about 5 W/cubic inch. Now the results are in, with the winners hitting 143 W/cubic inch using GaN transistors, and two other teams meeting Google's goal.

Is that you Thomas Edison?

I think he forgot the /sarc at the end of his post.

You are assuming GP male. This kind of sexist assumption is exactly the type of thing that needs to be stamped out in the industry.

Now if you need me, I'll be in my safe space. /sarc

There's probably a joke to be made at your expense, here.

And in English no less, the third most commonly spoken first language in the world. Could we please get these summaries in Mandarin and Spanish? If we're going to base things in the US on what more people are doing elsewhere, why stop at measurements?
