Here is a rowing machine that not only gives you a good workout but lets you generate your own electricity. The G260 ECO-POWR Rower from SportsArt has a microinverter built-in. It comes with an electromagnetic braking system to simulate the feeling of rowing on the water. It has a color changing LED light that shows you the amount of watts being generated in real-time.
This rower has fingertip controls within the handlebar that allow users to adjust resistance level on the fly. The G260 not only gives your body a good workout but offsets your carbon footprint.
