My Idea is to somehow take the hashing power of mining pools,and allow organizations to buy it up for applications such as Folding at home.
We need some sort of centralization to rent out hashing power,why not use mining pools?
I have similar idea that distributed computing projects of
(BOINC) Berkeley Open Infrastructure for Network Computing should gives tokens/coins to volunteers contributing in by processing block of raw data using their computing resources.These tokens would be traded like alt coins.Whole mechanism is needed to be developed to verify work.
One thing is for sure, proof of work could only be supplied by a scientifically trusted organisation like NASA or CERN.
I will be posting details of my idea at later time.
