Originally published on The Lenz Blog by Karl-Friedrich Lenz Says this article at Nature Geoscience. Their numbers: If the contribution from wind turbines and solar energy to global energy production is to rise from the current 400 TWh to 12,000 TWh in 2035 and 25,000 TWh in 2050, as projected by the … [continued]
Now even 3M is getting into the solar biz. The huge Minnesota company is famous for the Post-It Note and other mainstays of Western civilization, but now their excellent materials scientists have been put to work creating a reflective foil that can be used to make the (already rather cheap) … [continued]
It is not the world record for ALL solar cells, but for solar cells using certain cheap and highly available materials, IBM has just set a new world record. The world record is for solar cells composed of copper, tin, zinc, sulfur, selenium, or similar materials. The new record is … [continued]
A wind turbine efficiency breakthrough by Dr Markus Mueller and Dr Alasdair McDonald of the University of Edinburgh’s Institute for Energy Systems has the potential to revolutionize the wind energy industry by making large turbines more failure-proof by cutting their weight in half. [social_buttons] It is expensive and hazardous sending … [continued]
A Peruvian engineer has created a device that drops the use of mercury in the gold mining process by instead using “a foam flotation process with simple gravitational techniques” to separate gold from rocks.[social_buttons] The most commonly used process in developing countries uses mercury to separate the gold from the … [continued]
