Now add a pedal-assisted electric bicycle built for two to your eco-friendly gift list, even if it happens to be on the pricey side of the ledger.
A young man from Pakistan, Farrukh Khan, has built an interesting homemade solar-powered electric tricycle for a price tag that comes well under $600. Khan even provides detailed photo and a design template on the Instructables website for a small monthly subscription fee ($1.95 – 3.95).
A tunnel in Belgium built to protect high-speed trains from falling trees is now covered in 16,000 solar panels (yes, you may remember Tina covering this project a bit as it got underway last October).
