People tend to think electric cars will be more expensive and unaffordable than their petrol/diesel relatives. Furthermore, people usually expect high maintenance costs, because of the batteries.

Usually, plastic bottles, (aka PETs) are recycled by mechanical technologies, and they get several other uses afterwards: carpets, sweaters, etc. They don’t ever return to their original water bottle use.It is possible to chemically recycle PETs, but the method has been so far very expensive and the industry doesn’t want that option.

The world’s first commercial wireless EV has been introduced on Tuesday in South Korea at a theme park in Seoul. It’s called the “On-Line Electric Vehicle” (OLEV), and it gets its energy from cables underneath the surface of the road. The car doesn’t make any contact with the road, all the energy is transferred by magnetic induction.

Besides its search engine activities, Google focused on producing alternative energy technologies, or improving the existing ones. So is the case now, when Google developed a new mirror technology that could help solar companies like eSolar or BrightSource make cheaper and better solar thermal plants.

Yi Cui, a researcher from Stanford and his team have succeeded making office paper into an electrode by dipping it into nanotube ink. The resulted dipped paper becomes a strong, flexible and highly conductive material that could be incorporated into lightweight batteries or serving as an electrode in high-energy ultracapacitors. The nanotube-treated paper can store much more energy than classic batteries.
