One solution to the world’s water pollution problems could be something you can’t taste, touch, see, smell, or hear. Especially hear. Ultrasound, the range of frequencies beyond the limits of human hearing, is starting to emerge as an effective water treatment that is more sustainable than chemical dosing. Researchers are … [continued]
Overview of the long planned international line of the Pacific Northwest.
Move over, silicon: graphene is ready for its closeup. Discovered just a few years ago, graphene is a sheet of graphite the thickness of just one atom. It can be processed like silicon to make electronic devices, which makes it easier to manipulate than the current “it” material, carbon nanotubes. … [continued]
A look at the California high speed rail project and its development.

[social_buttons] Scientists have discovered a remarkable, unexpected and cheap way to store hydrogen fuel– using carbonized chicken feather fibers. The problem of storing hydrogen as fuel has traditionally been a perplexing and expensive dilemma. For instance, a car with a 20-gallon hydrogen storage tank made from carbon nanotubes or metal … [continued]
Composting will prevent tons of material from going to the landfill, create healthy soil for our local farms and help us fight global warming. Today at the Farmer’s Market in front of San Francisco’s iconic Ferry Building I am signing the nation’s first mandatory composting law.

The California solar market faces a serious potential roadblock next week, warns Solar Nation. The policy that allows us to roll our meter backwards when we generate more solar electricity than we use — Net Metering — is capped at 2.5 % of system peak load. Once we reach that … [continued]
Hydrocarbon (HC) refrigerants are a “natural” cooler widely used in domestic and commercial refrigerators all over the world, except in the U.S. and Canada. HC refrigerants produce less greenhouse gasses than hydrofluorocarbon (HFC) technology, but they aren’t approved for the U.S. market – yet. Now Greenfreeze, the Greenpeace-developed HC refrigerant, … [continued]
