A clip and pulley system which could hook onto a barbell or kettle bell would be great. Hrmm, perhaps this isn't so feasible. Performing a clean & jerk of 95 pounds to a height of 7 feet would yield about 900 watt seconds of potential energy. So even if you had a very efficient laptop (15 watts) and perfect energy conversion, you'd have to perform a clean & jerk every 60 seconds to keep computing. Even if you were in good shape, you probably couldn't keep that up for more than a hour. http://hyperphysics.phy-astr.gsu.edu/hbase/gpot.html http://hyperphysics.phy-astr.gsu.edu/hbase/gpot.html
