Green Tech News From Around the World

Soaking-Up CO2 from Power Plants: HECLOT from Taiwan Captures up to 90 Percent of Emissions.

The capital cost of a HECLOT power plant is $125 million for a 50 MWe unit, much less than the current cost of around five billion USD for existing CO2 capture technology. This will make it easier to raise capital for HECLOT power plants, which would result in a higher and faster financial return on investment. HECLOT can also be integrated into retrofitted plants.

100 Watt Renogy bendable solar panels

I just bought  a Renogy 100 watt bendable panel to add  to my 12 volt house solar array. At four pounds it is four times lighter and smaller than the 75 watt Siemens panels I bought over a decade ago. Not sure if they will hold up as well and I'd be leery to walk on it. But, I'm impressed with it so far. Gave a nice bump up in energy collection and easily movable compared to the rigid panels.:…See More

Sometimes it's the little things that are the problem

I was on the return leg on a recent cruise and tied up to a dock for a change to recharge the battery bank. The four 8A4D AGM batteries initially charged up fine. But, by morning one of them only showed a charge of 30%. In the back of my mind I thought it might be a battery failure, but, happily it turned out to to be just a loose connection on a fuse.…See More
