Energy in Chemical Processes & Everyday Life (video 6:39) – Energy is neither created or destroyed but is converted. Most of the energy is delivered to our planet from the sun and is harvested through the process of photosynthesis.
Energy harvesting – find sources of energy that are being wasted, or at least not used and gather and use the energy.
- microwave energy – gathered energy was enough to run low-power gadgets like thermometers, timers, and scales.
- recharge batteries from the energy seeping from power lines, refrigerators, and coffee machines.
