I find it hard to believe that a dynamo that produces much more than 6 Watts isn't realistic. If I ride at 200 watts (which for a fit cyclist is sustainable for long periods of time), that would only be 3% of my output converted, if I ride at 100 watts (should be sustainable for many people) that's still only 6%. What would a diesel driven generator get?

Edit: Found a more powerful dynamo here https://www.amazon.com/MNS-Power-Bicycle-Generator-Dynamo/dp/B003GJL6GO

Maybe something like this

You can purchase DIY generators to attach to an exercise bike, like this one, for example. You ought to be able to power a laptop for a while, provided you were careful to match the input to avoid burning anything out.

I started a project like this, but won't finish. If anyone wants the generator and belt you can have them. I won't ship, you have to pick up (in Seattle).

Here's a pic of the generator and belt:

It's this 'why even bother' that continues to doom renewable energy. I ask why not try it? Also they have 'pedal r' that supposedly produce more energy than these record cyclists. There is one on amazon that would seem to generate quite a bit if used continuously around 8 hours a day for an entire year. It's DC power though and would have to be converted to AC for normal grid use so there would be losses. i'm not sure how much.
