Commenting on Mark Jacobsons Energy Source Rankings

Mark Jacobson, a professor of civil and environmental engineering at Stanford, has written a review of solutions to global warming, air pollution, and energy security which examines all energy sources. The Jacobson analysis is very biased in favor of wind and against nuclear and biofuels. Nuclear power is burdened with CO2 from “burning cities in …

Graphene is the strongest material ever

A new and highly reliable approach for making graphene membranes of a macroscopic size (currently up to 100 μm in diameter) provided a lot fo graphene samples for strength tests Such measurements had never been taken before because they must be performed on perfect samples of graphene, with no tears or missing atoms. Graphene transistors …

Lorentz Force propulsion Successful test

Since the recent trial [with explosive arcing problems] , Peck and his colleagues at the University of Michigan and State University of New York, Binghamton, have successfully tested (but not yet published) their propulsion system, which could speed satellites along at more than four and a half miles a second. More recent tests of solder-less …

Cheap titanium, virtual telescope, property rights in space

Titanium could become a lot cheaper and more commongly used. A non-melt consolidation process being developed by Oak Ridge National Laboratory and industry partners could reduce the amount of energy required and the cost to make titanium parts from powders by up to 50 percent, making it feasible to use titanium alloys for brake rotors, …

Thermoelectronic advances

Recent quantum dots are three times better than thermoelectric devices from the mid-1990’s. There are quantum wells that get 4.5ZT. Vehicle efficiency technology gets about 176 million per year The new thermoelectronics are not magic technology. They are part of one of the highest value US government research programs. The advanced versions should be ready …
