Comments Off on Podcars Running At London’s Heathrow Airport

Modern Personal Rapid Transit, or PRT or podcars, are finally being put to use in London’s Heathrow Airport. I have called it a solution in search of a problem, and here they found it the perfect problem: getting people from one point, a parking lot, to a second point, the airport, on demand. Instead of having buses running all the time, one can call for a car when needed. It uses 50% less energy and is moving 800 people a day. Jim Witkin raves in the New York Times , and Richard Gilbert in the

Comments Off on Studying Radioactive Sulfur From Fukushima Teaches Us About Coal Pollution From China

In amongst all the coverage of and concern about the Fukushima nuclear disaster the fact that air pollution from coal power plants in normal operation kills far more people each year than does nuclear power rose to the top. As for the fallout of that nuclear disaster, Boing Boing has an interesting new story on how studying the radioactive sulfur from Fukushima is helping us learn more about coal pollution–and how … Read the full story on TreeHugger

Image Source: cthoyes Dear Pablo: I have heard that using a programmable thermostat to lower the temperature while you are out saves energy but isn’t the same amount of energy used to bring the temperature back up when you come home? The short answer is no.

Comments Off on Gold Nanoparticles Could Lend Green to Fabrics and Fragrances

A team of Harvard scientists has discovered that gold nanoparticles could be used to produce fabrics and fragrances .  The process is cheaper and more energy efficient , and it emits fewer pollutants than conventional production methods.  The breakthrough is more proof that sustainable manufacturing methods can achieve bottom line benefits along with improvements in public health and environmental safety. Headed by Professor Cynthia Friend , the team found that gold nanoparticles can oxidize alcohols and aldehydes (formaldehyde is a familiar example of an aldehyde) at room temperature.  The process uses less energy than the high heat required by conventional methods.  If the process can be scaled up for commercial use, it could significantly reduce the carbon footprint involved in manufacturing synthetic fabrics, fragrances, essential oils, and perhaps other products as well

Individual control: Air Conditioner in a Can from Japan A new study from the Center for the Built Environment at the University of California, Berkeley, confirms what everyone probably knew intuitively: If you give people control of their own environment they use less energy. According to the New Scientist, by installing individual vents and controls for each worker (which automatically turn off when the desk is vac…
