These Strange Metals Could Make Electronics Perfectly Efficient

Want 100% efficiency electronics? How about levitating transportation? Faster supercomputers? Duh-duh-nuh-nuh!!! Superconductors to the rescue! As long as the world you live in is close to absolute zero, that is. See, superconductors are materials with all of these amazing potential applications…but the conditions required for them to work are pretty extreme. It’s gonna take a […]

Not all the energy is the same : simplified comparison of electricity and natural gas

Hello everyone. In many of my videos I have talked about how there is the difference between mechanical energy, electrical energy and thermal energy, even though they can be measured with the same units of Joules or kilowatt-hours or any energy unit But I never really explained this difference.
