What on this planet? When? Why? Where? got the solutions? Twitter consumer Booky McReaderpants asks, “Why can’t I power my dwelling making use of a bicycle-powered generator?” that is a just right query To seem for solutions I am here in Rochester, big apple This position was once the bike capital of the us They even had a countrywide magazine about bike paths and its the house of University of Rochester astrophysicist, blogger and NPR contributor Adam Frank he’s going to help us figure things out. Hi there Adam! What’s up Adam! How’s it going? So the first query is I imply, there are the lights the air conditioner the microwave the dryer the refrigerator the water heater And it all provides as much as about 900 kWh every month. Coal – burned at this Rochester power plant. And water, that turns the turbines at this hydro station on the Genesee River. In spite of everything, earlier than the economic revolution, all of us trusted the vigor of humans and animals So let’s get mounted.
Adam’s legs flip the wheel hooks as much as the generator and turns that movement into electrical power And that electrical energy is stored in the battery, in order that I will be able to use it later on, even when Adam isn’t peddling Now if Adams is going to power my residence identical to that powerplant, he’s going to need some gasoline this is the “Garbage Plate” It comprises about as a lot of energy as a cup of gas roughly 2 kilowatt hours unfortunately, Adam’s not an extraordinarily efficient computer He can simplest convert a few quarters of the fuel he eats into energy and some that vigor is simply going to, you already know, maintaining him alive his lungs breathing …
His coronary heart beating … His digestive system digestive … With the vigor that’s left, an elite bicycle owner can generate about kilowatts for an hour but Adam … He’s now not an elite bike owner And I need him to go for lots longer than an hour If he pedals for eight hours a day, the exceptional he’s going to be in a position to keep is about 1 / 4 of what the elite cyclists can do And that sums as much as about 1 day per day that may be adequate to maintain this lamp going, but do not forget, our whole system? It’s inefficient. Some of that power gets misplaced on its approach through the generator and some on the best way from the generator right down to the battery So at the finish of the day, there’s handiest a couple of 1/2 of a kilowatt hour in the battery If he pedals all day for a month scarfing down a hundred and twenty garbage plates he’ll retailer away a grand whole of sixteen kilowatt hours The same amount of power in half of a gallon of fuel strike a cord in me, how so much does your residence need once more? 900-kilowatt hours per thirty days.
It will take FIFTY Adams pedaling additional time to energy my house. And it could take the complete populace of New York city to vigor every condominium and industry in Rochester And that Booky McReaderpants is why you can’t vigor your apartment with a bicycle Ask Skunk undergo more questions right here and subscribe to our channel to comply with the solutions And which you can ask me questions on twitter @adamfrank4 or take heed to NPR for extra short solutions to giant Questions.
