We also found many discussion groups doing serious thinking while I doubt that those ideas finally make their way to TEPCO.
There is an approach to bundle ideas and risk analysis in a Non-profit Open Innovation portal as contribution to end nuke crisis in Fukushima.
The situation at Fukushima Daiichi is still as difficult as 4 weeks ago. Engineers struggle to stabilize the situation and progress is difficult to achieve in view of numerous issues to be solved simultaneously.
To bundle technical expert knowledge - now distributed over a number of web sites - InventCap started a nonprofit open innovation portal "Help to stop nuke crisis in Fukushima": http://system.aipivalue.com/fukushima
Technical proposals about health and environment protection, cooling systems, radiation protection, general plant repair issues and measurement techniques will be collected and rated. Promising proposals will be forwarded to IAEA and TEPCO.
Considering the huge risk portfolio in Fukushima and the threat to people there it sounds worthwhile to try all means to get ideas organized and forwarded to the crisis management.
