For those cloudy days, and to stay in shape while at sea... ;)

I found this along the way and thought I'd share... seems interesting at the very least.

When sailin in Aust, my kids always wanted on the laptop or the playstation, so I made a system for the push bike. Basically two rollers attached to each other about 150 mm apart for the back wheel to ride on & an A-frame to keep the bike up straight, from a bracket a alternator pressed hard against the back wheel. Alternator connected to a single battery with an inverter with a british wall plug so that they could not plug it in anywhere else. They had to two peddle of about 2 hours to put enough charge in the battery. How eva I landed up useing it more than the kids.
