In other words.... scientific "consensus" has muddied the waters to the point that no one can see anything. "The watt (symbol: W) is a derived unit of power" (from above) ... note the term "derived" ... this is a "science by consensus" term to "define" things and to ultimately limit knowledge. I contend that there is little relationship, other than the manipulated mathematical one derived by "consensus science", that is in any way relative to reality. I have built, tested, and have the working model to prove that one can run a alternator with bicycle power and generate electricity ... no matter what "consensus" and "mathematics" says is possible. Tesla ran across this problem, but I am in no way comparing myself to him, just using his experience with "known science" to illustrate my point of "known mathematics" and "consensus science."
Isn't that what permaculture is all about? Breaking all of the "rules" and finding ways that really work? Never mind what the science and the manipulated mathematics tell you, just dig in and experiment ... follow that little voice in your head that says "what if...." and dare to try something that the "consensus science" says that will not work through their manipulative mathematics of "derived units." Remember that mathematics and numbers only exist in man's mind and not in "nature." You will never see a mathematical equation in your garden, unless you subscribe to "science by consensus" and look (very hard) for it.
Just dig in and break the mold and try something new. That is how rocket stoves have been developed and improved over time. Then share your results for others to try to improve on. That is all I am doing here. Try it ... you'll like it! Or prove me to be a fool. Either way ... how can you lose?
PS: I am not interested in selling electricity, power, or anything else, I am just extremely lazy and just want to have the best possible life with the lest work extended and that is the basis for all of my experimentation. If necessity was the mother of invention ... laziness was its father. I built my working model on a hunch and it worked, and I filed it away for future use if needed. I am in no way trying to sell or profit from this "knowledge" that I have stumbled upon, just sharing freely. If you don't think this will work .... try it and prove me wrong. I have nothing to lose and I have a working prototype for my extreme needs.
Larry Noel wrote:I need to make an input here. What is being discussed here is "mechanical watts" which is in reality not related to "electrical watts." "Mechanical watts" is a mathematical function between calories burned and horsepower output. "Electrical watts" is a mathematical function of volts times amps. While it may take 400 "mechanical watts" to power a bicycle for a given time, that physical energy of the wheel turning can be used to turn a car alternator which will have an electrical wattage output that is in no mathematical relationship to the mechanical watts consumed. Make sense?
Several years ago I had an old 26" English racer with the super skinny tires. and I took the rear tire off the rim, got the longest fan belt that they had at the auto parts store, and built a plywood stand to hold the bike upright. I got a 100 amp single wire alternator and rigged up a spring tensioned mount in line with the fan belt and hooked it up. The single wire alts need 12 volts in the system to "excite the field" and turn the electric magnets on to start generating amps. I am not sure what RPMs are needed, but as long as that speed is maintained the thing will make amps. I ran it once with a meter on it and it was putting out 13.8 volts at 85 amps at the speed I was pedaling and that is a pretty good rate to charge a battery at. Anyway I had my proof of concept working and I put it away and it is in the "just in case" worst case file...ready to go. In a worst case where all you had was this and a dead battery a solar panel could be enough to "excite the field" and make it start generating amps. Watts = Amps times volts so 100 amps at 12 volts is 1200 watts. Pedal for an hour and you should have 1200 watt hours stored. Thats the theory at least. Like I said, it works and I put it into the special file as a back up to may back up. Cost: $20 for bike+$100 for alternator+$30 fan belt=$150 experiment and a few hours and nuts and bolts with scrap plywood. I call it my "Gilligan's Island" generator.
A trained cyclist can produce about 400 watts of mechanical power for an hour or more, but adults of good average fitness average between 50 and 150 watts for an hour of vigorous exercise. A healthy well-fed laborer over the course of an 8-hour work shift can sustain an average output of about 75 watts. The yield of electric power is decreased by the lack of efficiency of the human-powered generator, no known generators are 100% efficient.
