South-Korean Automakers Could Help Make EVs More Affordable
I have a love/hate relationship with concept cars. It’s always fun to see what automotive engineers can come up with, and they have a lot more freedom to innovate with concept cars than with production models, but a lot of the time, the results can be impractical and/or silly, and you just know that they’ll never make a production version. That’s why I’m happy to see that Kia’s electric car concept is based on a production model. Read on for the technical specs…. Read the full story on TreeHugger

Innovations that help us get the lead out of electronics is a really big deal. The heavy metal is a big source of pollution in soil and ground water tables due to electronics being tossed in landfills, and is a toxic substance in e-waste dumps. University of Maryland is working on what could be the first commercial replacement for the lead used in transducers, actuators, sensors and other components.

If you’d like to know just when enough is enough in the shower, but you don’t want to go the route of a system that just shuts off the water and leaves you with soap in your eye, or worse, surrounds you in claustrophobia-inducing inflated bubbles, then the more subtle waterpebble might be the solution for you. By monitoring how much water heads down the drain, it let’s you know when you’ve crossed over into water-waster mode. Eve… Read the full story on TreeHugger

The time change isn’t here quite yet, which means many of us are still riding our bikes home in the dark after work. A bright bike light is therefore a must, and there are a lot of systems available that gather a charge while cycling. The newest one is a system that hooks up to your bike wheel but is entirely frictionless, relying instead on magnetism. … Read the full story on TreeHugger

Sunlight + Water = Hydrogen Gas
Scientists at the University of East Anglia, led by Dr. Thomas Nann, report a breakthrough in the production of hydrogen from water using the energy of sunlight. Amidst all the hype about a potential hydrogen economy, which would rely upon the highly energetic and clean burning hydrogen atom, one of the big questions has been whether sufficient hydrog… Read the full story on TreeHugger

From effective masonry heaters to beautiful Danish wood stoves, the Scandinavians know a thing or two about heating with wood.

Dave Levitan writing for SolveClimate has published an excellent survey of what the future may hold for the ‘More than 60 proposed US nuclear projects, scrapped in the 1970s and early 1980s.’ Some are nothing more than unapproved plans on paper (there was no CAD back then – so hand drawn), others are in various states of completion and “mothballed,” some were started up b… Read the full story on TreeHugger

Dumb Roofs
Renew magazine for Jan – Mar covers a lot of ground in its 106 pages on “technology for a sustainable future.” But for me the stand-out article covers a subject dear to my heart. The dumbest idea in Australian architecture – black or dark grey roofs.*
We get a bucketload of sun in this country. Just recently several of our major coastal cities had consecutive days over 40°C (104°F). What are the best colours to attract the hot sun’s rays? Black and dark grey. It’s madness. We’re building houses to be be ovens and so… Read the full story on TreeHugger
