While some study ways of electronically controlling the shock absorbers and giving you a smooth and steady ride, and others are seeking ways to convert the heat generated by the engine into electricity, a team of undergraduate MIT students invented a shock absorber that harnesses the energy from the very bumps it hits. Several truck manufacturers and the U.S. military have given them attention, and planned to use their technology in their cars.

This DIY presents a device capable of detecting the stand-by mode of low-consuming electronics in your home (like plugged-in phone chargers, without the phones attached) etc. The metering starts when the devices enter stand-by and stop when they start consuming in large amounts.
