A Bridge Between Private and Public Transport. It’s a small non-polluting vehicle that not only works on a giant organized system that reduces traffic and travel time to a minimum, it’s made to encourage car-pooling as well. The vehicle runs on Li-On batteries, recharged by solar panels on the roof of the vehicle. The batteries can also be charged at any number of special zones in the city through induction charging. Love this idea and wish we would see it in cities everywhere!

Tire Made of Orange Oil Uses 80% Less Petroleum. Yokohama’s new Super E-spec tire, which is made in part from oils extracted from orange peels, is composed of 80 percent non-petroleum materials and has improved rolling resistance, meaning it is more fuel-efficient.

Solar aircraft to circumnavigate the globe. The plane is made out of carbon fiber materials, has a wingspan of about 200 feet, and it’s covered with over 12,000 solar cells that power four individual 10-horsepower motors. I don’t know about you, but I wouldn’t want to be the test pilot for this plane!

Clock powered by just water and lemon juice. No batteries needed – just tap water and some lemon juice is all that is needed to keep this clock ticking!

Fake trees to help clean up CO2 emissions. Not sure why we need this when “real” trees do this job just fine, but hey – who am I to judge? A modest geoengineering concept is to build “synthetic trees” — essentially high-tech towers with special absorbents that scrub carbon dioxide from moving air, and then hold it until it can be processed and stored. I guess they could put these up in bulk, whereas real trees take years to mature. What do you think?
