A Resistor “resists” current flow. Think of it as a restriction in a water pipe only for electricity.

A capacitor blocks DC current but allows AC current by essentially charging up like a tiny battery, once charged the capacitor stops allowing current flow until the flow reverses.

Peltier Coolers or Thermal Electric Coolers are used to make things hot or cold but have another cool use. Apply a heat source to one side and keep the other side cool and the Peltier generates electricity.

There are many advantages of having an automatic chicken coop door. The door will automatically close at night when the chickens are inside and open in the morning. Not only will they stay warm and cozy, critters like coons and skunks will have a much harder time getting to them. The ultimate luxury to me though is the fact that I don’t need to go out and lock them up and get up at the crack of dawn to let them out.
