Go to the gym and ride the stationary bicycle and you'll see that producing a mere 150 watts (assuming the bike you get shows your effort in watts) will make you soon ready to puke. 300 watts per human on an extended basis is a JOKE.
From a simple engineering systems perspective, this makes no sense whatsoever. It takes lots of processed carbohydrate fuels to power the human body.
I was thinking the same thing, intuitively, with out the math. It takes fuel to make the machines that plant, harvest and transport human food. It takes fuel to power the factories that produce the processed carbohydrates, and then transport them to the stores, where we burn fuel to go retrieve them. And then you have to enslave people to ride FIFTEEN bicycles to power a puny number of low consumption LED lights.
These people are psychotic @$$holes, and they have to be stopped, or we'll ALL be slaves, not just the ones chained to the power generating bicycles.
Excellent amplification on my comment, HSB! All the energy to plant, water, fertilize, harvest, process, transport and store food -- then feed the food to people, chain millions of them to benches and make them galley slaves. We struggled for millennia to harness thermodynamics to free people from the drudgery of daily existence and now they want us to forsake all of our knowledge and return to primitive lives? These people ARE psychotic and without a single SHRED of common sense.
This is the future these lunatics foresee for all of us. Chained to the State and chained to the oars.
