As long as you don't mind the trailer of solar panels dragging along, you'll have endless energy.
We've been using the sun as a source of heat for ages, and in our modern world, we’ve just refined our usage of it. Considering climate change's worsening effects on our world, engineers have to turn to alternative types of energy rather than fossil fuels, and solar energy is a perfect candidate since it is renewable, limitless, and versatile. We can use it to power everything from cars to tablets, and in this video, YouTube channel PeterSripol tackles the project of making an infinitely powered solar e-bike -- which looks cooler than it sounds.
Now, electric bikes are pretty amazing, but they have limited range due to their compact battery packs. So naturally, he was curious to see whether he could build an e-bike that never needs recharging as long as there is a sunny sky out.
He executes the build in what he calls "probably the simplest way" possible: He takes a motor and makes it touch the wheel to create a drive system. With the solar-powered e-bike and a sunny sky ahead, he tests his design out with success. While it is admittedly not the most efficient thing ever, it's certainly a cool idea with simple execution and provides great understandable educational content. If you're curious to see the result, make sure you watch the video embedded above.
