Imagine wearing a smart T-shirt or a suit embedded with tiny electronics that can monitor your heart or respiratory function wirelessly. When dirty, you take it off and throw it in the wash or have it dry-cleaned.

Harvesting the Power of Ocean & Tidal Energy - 0 views

A small team of engineers based in Cornwall, England, have made a breakthrough with the development of a turbine that they claim could solve the commercial viability of tidal power. Known as the Osprey turbine, the technology can be used to create electricity offshore at sea -- or in tidal rivers and inland waterways. The Osprey turbine is a vertical axis free flow device which produces power independently or as part of a larger system. Power output is expected to be from 1 kW up to 5 MW in a multiple system.
Biofuels and Food Security should be a very important aspect of this group - 154 views
I agree that biofuel is a dead end, and in fact is perhaps worse than the disease. I will cross-post some recent articles I have found on biofuels and the scramble for African land (and land elsew...
SMA Solar Technology AG enters micro-inverters market through acquisition ~ Cleanergy.o... - 0 views

Micro inverters are particularly well-suited for the use in small photovoltaic systems of 1 kWp or under. In some larger photovoltaic systems which use string inverters, shading of individual modules and the subsequently lower energy harvest of the entire system can be avoided by equipping and operating those modules with individual module inverters.

"Jernhusen, a real estate company in Stockholm, has found a way to channel the body heat from the hoards of commuters passing through Stockholm's Central Station to warm another building that is just across the road."
Using CO2 to Extract Geothermal Energy - 2 views
-
Is the geothermal market about to boom? It is one of the more difficult renewables to harvest. It requires exploration to find good resources. It needs deep drilling which is complex. There is a risk for imcreased seismic activity which is unknown. But if all can be addressed, it offers baseload electricity. The only other renewable that does this is hydropower.
IEEE Spectrum: Silicon Nanowires Turn Heat to Electricity - 0 views
-
Two separate teams, one at Caltech and the other at the University of California, Berkeley, reported that they could increase silicon's ability to convert heat into electric current by as much as 100 times. If they can use what they've learned to improve silicon even further, or translate their findings to other materials, the discovery could lead to new ways to cool computer chips, build refrigerators, or get more power out of car engines.

Carl Hodges walks along a berm on a research plot where he grows salicornia and experiments with different planting and harvesting techniques. Hodges and his crew have flooded the plots with saltwater from the nearby Sea of Cortez.
