Google Challenge Results In Astoundingly Efficient Inverters

Posted by timothy on from the now-multiply-by-a-few-million dept.

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.

    Thanks to all the AC for clarifying why Trump might become you president....

    As a side note: positively discrimination on a goal oriented challenge would be beside the point, after all you want the maximum of "what ever" from the winner...
    But not going through a phase of positive discrimination has two drawbacks, you get less talented people from the discriminated group, and you give the illusion to a whole bunch of idiots in the advantaged group that they are actually worth something in their chosen activity, instead of letting them either try harder, or change business.
    So as defined in the Hacker's Dictionary Loose Loose !
