Professor Sheila Kennedy and her students at MIT have designed the SOFT Rocker, a contemporary-looking lounge chair that uses solar power for electricity. You can charge your iPad or laptop while chillin' and rockin' back and forth outside. It uses your balance to create an interactive 1.5 axis and 35 watt solar tracking system. In the words of Kennedy:

"The SOFT Rocker blurs distinctions between pleasure and work and recasts power generation as an integrated and distributed public activity rather than a centralized, singular off-site project of engineering."
