Becky Stern writes, "Last year Hurricane Sandy knocked out a large portion of the power grid in New York City, and I was able to stay online thanks to this rig my friend Hackett made– it's a deep cycle battery, inverter, and stationary bike trainer with a permanent magnet DC motor and charging circuit. To deal with the lingering trauma of a very real natural disaster, we made a video detailing how it works."
