Question

Imagine you are visiting a science exhibition organised by a school in your town. One of the
models catches everyone's attention in the exhibition. It is a portable generator. You can carry it
with you anywhere and generate power by spinning a small wheel attached to it. Ten minutes of
spinning the wheel can generate enough power to light a CFL bulb for two hours. Write a news
report on this for your monthly school magazine.

Answer 1

Answer:

Pedaling a bike at a reasonable pace generates about 100 watts of power. That's the same energy-per-time used by a 100-watt lightbulb. So if you pedaled eight hours every day for 30 days (no weekends off), then doing the math, you'd generate 24 kilowatt-hours (kWh) of energy. Note that I'm not worrying about the efficiency in the electrical systems involved, which would drop the number closer to 16 kWh

Explanation:

That's only 2.4 percent of the energy your house sucks up each month via the lights, the dishwasher, running the AC and playing video games on your PS4 (like Deus Ex: Mankind Divided).
