Sky Windmills
Wired is reporting on an Australian engineer by the name of Bryan Roberts who has an idea to build a giant floating platform of windmills. The device will provide itself with enough power to stay afloat, as well as delivering additional power to the ground via a cable. Just imagine if in 20 years time we all have a giant floating little platform above our houses. The website on this can be found here.
At the same time wired is running another very interesting article on a robotic shark being used to study great whites. The shark looks very realistic and fits a full person inside. Be sure to check that story out too.
