Kettle

11 people on bike generators pedalling to boil 1 cup of water with a 1kW kettle.
Circuit includes 58F ultra-capacitor to smooth voltage and 1kW inverter with low-voltage warning which is audible throughout most of test.
Filmed by Paul Jenkins who also had to pedal because we were short of cyclists.

   What’s the …
   What’s the mechanical input in watts or HP?
   What’s the system efficiency? About 50%?
   Actual power to the 1 KW kettle? About 500 Watts?
   5 min seems like a long time to boil 8 oz of water.
   Ever try 11 Pro cyclists generating 6 HP at the pedals?
   At 50 % EFF that’s 3 HP or 2.2 KW at the kettle.
   Get a more powerful kettle, maybe 1-2 min to boil!
