Energy from Kelp
Domestic power from cycling
Professor Stott's calculations:
Ever optimistic, let's assume a small, highly-efficient, ecohouse requiring our cyclist to produce, on a sunny day, about 2 usable kilowatt hours (kWh) of energy (remember energy is measured in kilowatt hours).
A reasonable cyclist can produce about 260 W (watts) of peak power, although the figure for more continuous cycling is likely to fall to around 150 watts, and this is probably only truly sustainable for some 30 minutes. You therefore would need between 8 to 14 cyclists pedaling furiously for one hour to get anywhere near sustaining even the tiny demands of our ecofriendly house.
A top racing cyclist, a Super-Pedaller, by contrast, with around 150 rpm at crank, could just about produce, in old fashioned terms, 0.6 HP (horsepower), or some 440 watts of peak power. In this case, you would want around 5 'Tour de France'-level cyclists peddling in line with effortless ease for an hour or so, although this does not really allow for friction, energy efficiency loss, or sheer exhaustion!
