Solar and Wind Powered StreetLights In Tokyo

by Justin Thomas •

We just wrote about the new LED streelights in Ann Arbor. Now we find these self-contained streetlights that generate 100% of their power from the sun and the wind. During the day, solar power is stored in a battery at the base of the light pole. At night, they illuminate while continuing to generate power via a small vertical-axis wind …

Optimal Green Instruction From Allison Rogers

by Justin Thomas •

  Recently, I was lucky enough to meet Allison Rogers, who is now working with the House of Representatives to Green the Capitol.  Allison shared some of her optimal green techniques and  knowledge with me.

Yamaha’s $2000 Electric Bike

by Justin Thomas •

This compact electric bike, the EC-02 from Yamaha, costs just under $2000. First introduced in Japan two years ago, the EC-02 is similar to the Enertia motorcycle I wrote about recently in TreeHugger. But this scooter has more modest specs: a top speed of 18 MPH and a range of 40 miles. So it’s more suitable for commuters and scooting …

Flare Innovation: PowerFlare with LEDs

by Justin Thomas •

Invented by a police officer, PowerFlares are LED replacements for convetional flares. They have the advantage of not emitting toxic fumes or polluting the the ground. They also tend to cause fires, such as the one seen here. PowerFlares emit light in all directions, and can be seen for miles at night. Each unit is about the size of a …

Modular and Sustainable Walkways

by Justin Thomas •

There’s too much concrete in the world and most of it is unnecessary. Here’s one alternative that you may have seen at the beach: low-impact, modular walkways made out of sustainable timber. The company, Mister Boardwalk, even makes “roll out” walkways that simply roll out on top of grass, wood chips, sand, gravel or old concrete. The company specifies that …
