Alternative energy: changing electricity to heat. 1. Thermal jacket

Thermal jacket Sports guy Alternative way to replace the use of body heat: external heat. Hand generator/ batteries to generate the electrical heat inside the jacket.(?) ?- I don’t know what should go inside the jacket that would produce electrical heat.

Ideal project

Better Oxygen Intake: No pain, No gain

Idea I thought of mouthpiece or some-kind that will regulate the air intake for athletes. It is known that high-altitude training will expand the lung capacity. Hence, if we make a device that will act just like the high-altitude, we can help athletes to train lung capacity better than their normal training.

Portrait of the idea This mouth guard will have “levels” of difficulty, which Will control the oxygen insertion Making either harder or easier For athletes to breathe. Depending on the difficulty, this Will act as the high-altitude.
