Top riders can sustain an average of 700 watts at the pedals for an hour under occasional peak performance conditions.
I would like a 'perfect' active-synchronous bridge rectifier. Like four IR11672, but without the external components, in a standard bridge rectifier footprint.And a similar part for low voltage, perhaps integrated with a switching buck/boost regulator. That would allow using any power brick up to 24VAC with small gadgets.

The UCI hour takes around 500 watts average power for an hour and, pretty much by definition, that's the world record for average cycling power output over an hour. The 1972 record of Eddie Merckx has been calculated at 485 W average and that's probably the highest effort attained because, although the record has been broken several times since, the bikes have improved over the same period reducing the actual physical effort required.

If you need to dish out that total power in one second, then you got some real problems.Unfortunately they sort of glossed over those details in the movie.One thing I've always wanted to know is how did he fit a nuclear power plant into a car? It would have been more believable if the flux capacitor was based on nuclear fission directly rather than electricity.

Fluxcapacitor
You are correct, the reported 700watts I saw was for 1h and 25min, not 1 hour.
It was a fusion device, not fission. The name on the side of the unit said "Mister Fusion".
Quote from: BrianHG on May 19, 2017, 06:35:44 pmYou are correct, the reported 700watts I saw was for 1h and 25min, not 1 hour. Still something very wrong about that figure. That's a higher power output figure for a longer period, which common sense (and your aching legs) tells you is not the way that human endurance works. I think someone's quoted you figures for peak power output during a 1h 25m race, which I can believe, for an all out sprint in the final 200 metres of a race.
Hmmmm, that would be average 495watts/hour at an hour and 25 minutes, ...
VCCap = voltage controlled capacitance
Self aware MCU.
A fully complementary pair for the 6L6 vacuum tube.

I wouldn't want to be within a couple of hundred miles of a compliment to a 6L6 tube - if the envelope cracks and air gets at the antimatter electrodes, it will make the Hiroshima bomb look like a firecracker.
A reasonably priced portable multimeter (capable of uA measurement) that contains an inbuilt datalogger for subsequent analysis.

Depends on your definition of 'reasonably priced', I guess. Mine cost much less than the value of the job I needed it for, so it definitely met that criterion.
