Summary
The Global Innovation Commons, a repository of innovations that can be used because of patent expiration, abandonment, invalidity, or lack of in-country protection, has compiled a list of patent disclosures and open source technology that could be used as part of Japan's earthquake response--or even to cool down the rapidly worsening nuclear reactor situation in Fukushima.
Description
This isn't to say that experts the world over aren't already pooling together their expertise to help out Japan. And in any case, Tokyo Electric Power isn't exactly being forthcoming about its operations at the deteriorating plant. But who knows--it's possible that some enterprising scientist digging through these patents can come up with something useful.
