RE:RE:RE:RE:RE:Micro cleantechsHave a look at Sharc Energy. They make systems for capturing waste heat from sewage. Interesting concept, but they have barely any revenue; they are burning cash and have 3 dollars of liabilities for every dollar of assets. From the looks of things, they will have to do a financing in the near future just to keep the lights on.
They've been cranking out the news releases however, so the market is giving them a 20 million dollar market cap.
