You also need a big enough battery to get through slow hours. So you can get the Zero-emissions Off-the-grid gym!
minus-squareRivalarrival@lemmy.todaylinkfedilinkEnglisharrow-up8·14 hours ago but if you want the fridge you need five cyclists Your numbers suggest the fridge uses 5 * (30 to 70), or 150 to 350 watts. Which are reasonable numbers when the compressor is running. But, the duty cycle of a fridge is typically less than 30%. It only draws a couple watts with the compressor off and the door closed. In a long enough “race”, two cyclists should be able to drive the electric meter backward faster than the fridge drives it forward.
