For renewable energy on a smaller scale, a graduate student in Israel developed a prototype for an elegant rocking chair called Otarky that produces energy from its rocking motion and can be used to charge devices and power a lamp.
In "SmartEco" mode, the projectors automatically adjust lamppower to maximize power savings by delivering the best contrast and brightness performance using only as much light as needed.
It was also a hot week for energy-generating tech as Intel unveiled a solar laptop chipset that can be powered by a desk lamp and MIT developed a tiny kinetic generator that can produce 100 times more power than previous devices of its kind.
