What’s all the hype about “Alternative Energy”? Are there really better ways of making the same energy for less? Absolutely! One of the biggest challenges we have right now is how to extract the energy that’s already around us. For example, the amount of energy in a gallon of water could power all of the USA for a year, if we only knew how to harness it safely.
There are many different forms of energy floating around you right now: solar batteries capture the heat and light energy from the sun and store it for later use; geothermal energy uses the difference in temperature to do work; the energy from rushing winds and rivers can be used to turn a motor; and the energy inside light waves themselves can be tapped into so you can hear radio signals using a battery-free radio.
We’re going to cover all this and more, including how to get energy from the water molecule to power a vehicle AND how to build robots that use only solar power (and never need a battery recharge!) Are you ready? Then let’s start with this video:
