- Do you think you can generate enough electricity using a bike to power your home? Dave gets on his bike to find out how much pedal power it would really take to charge up some everyday devices.
Biking might not be the most efficient way to generate electricity but it sure provides a great work out.

About BC Hydro
Here at BC Hydro, we make clean electricity, powered by water. It’s our job to make sure people in B.C. have a reliable source of clean energy to power all the things they interact with each day.
Join us as we explore smart energy use, electrical safety, and behind-the-scenes looks at our work throughout the province.
Um, it's a nice video, but "60 Watts per hour?" A Watt is a measure of power: energy per unit time. If you generate 60 Watts pedalling, then you generate 60 Watts whether you pedal like that for five minutes or ten hours. If you pedal for an hour, generating a consistent 60 Watts, you will generate 60 Watt-hours of energy. It doesn't matter how long you pedal, though, you will never be able to run your coffee maker at 60W if (like most typical coffee makers) it is rated at 750 W or more. If Dave is charging up a battery that will then be discharged at a higher rate to power the devices, that's different. BC Hydro should know this stuff.
A bicyclist can produce 250-+ watts pedaling and the best you can get out of it is 60 watts/hour? SERIOUSLY?
I have no idea how efficient the alternator is.
100..200W should be doable for a working day, so biking while actually doing work. You probably need to go recumbent style too...
I miss flying wheels to keep the pace and bike resistance constant.
I've been looking for a working setup for a long time. Usually bike alternators limit power internally to 6W.
Maybe engineers can build a bike with a fly wheel etc...that's 10x more efficient than that homemade thing you put together...🤔
It takes only one minute, not twenty, to pedal-power enough smoothie for 4 people. I know 'cause I've done it often. Admittedly, pedal-powering a household is a big job, but please don't further belittle the small ones...
What do you use? ❤
@@PJHROSECreations I use a treadmill motor (100vdc) with a 1.25" diameter spindle driven by a road bike clamped to a training stand. The motor, wired to a 2-prong plug, connects to an older blender (max. 400w) and runs it very nicely. Grinding through the ice is harder, then it gets easier as the smoothie gets smoother. The generator outputs up to 150volts. Once with friends, we burned out an incandescent bulb by sprinting. Cool.
You can only hold 60 watts for an hour?! That's really low. I'm not even that good of a cyclist and I hold 270 watt for an entire hour. Average person should be able to hold 150. Pros hold ell over 350+.
ikr, but that's raw power, when you actually have to power something there will be various losses. Just like a typical usb powerbank will only give you about 75% of it's actual capacity depending on the perspective. Just try adding like 10 oldschool bike dynamos to a wheel, would probably provide 50-75w of raw power depending on the speed. I do like the concept tho..but this is more complex than I can explain
60wh times 2h = 120wh to charge a phone ?!
The b9g phones have 5000mah batteries X 3.6 nominal= 18wh . So why do u need 120wh to charge a 18wh phone battery?
Because phones aren't charging at 60w.
You mean sixty watt-hours?
What if you had a penny farthing?
They lie , its 100 Watts
