Solar panel sun tracker for $10

SunSaluter: $10,000 Winner of the EcoLiving 2011 Student Leadership Award from Scotiabank's EcoLiving on Vimeo.

This is truly inspiring.

Eden Full, a 19-year-old Princeton University mechanical engineering student has developed a non-toxic, cheap, recyclable device made out of metal and bamboo that allows solar panels to follow or track the Sun without the use of an electric motor. This does two things: 1) it boosts the output of the solar panels by about 40% (huge) and 2) it does so using a much cheaper and simpler method than traditional trackers commonly used in commercial projects (her technology costs $10, a lot less than the typical $600 solar tracker).
