Solar cell window

I had brilliant idea the other day. I though: "Let's make a special windows that would be like a two-way mirror but instead of a mirror on the bright side, it would be a solar cell that convert some light into usable energy." All those building and skyscraper with curtain wall could be self-sustained during the day.

Sadly I wasn't the first to have this idea. Scientist at Brookhaven National Laboratory and Los Alamos Nation Laboratory are already fabricating transparent films which are able of generating an electrical charge by absorbing light.

Urban Transport

Have you ever dream of a small automated method of transportation that take you from point A to B without having to actually drive it without the hassle of a bus? This might be closer then you imaging. A company name Ultra PRT are actually designing and build a new form a transport. Their name stand for Urban Light TRAnsport Personal Rapid Transit. They are making a system of small electricity power vehicle that wait at specific location near a track, waiting for a user to get in and give the vehicle a location he need to reach. They are already building one at the London Hearthrow airport to link a station with two remote other station in the airport car park.

You can see a nice video about the system here:
