Is it possible to harness electromagnetic energy in our bodies?

Answer 1

yes it is from kinetic energy to a mechanical interaction to change energy to eletrical energy to power somthing. thank you WikiAnswers.com for the research help. this website helps you a lot, take advantage of the resource!!

Answer 2

The body does have electrical impulses within the nervous system-whether there is any way of harnessing this is a biological question. However looking at it as an energy matter one can calculate some facts. The average adult male consumes about 2500 kilocalories per day of food, which is equivalent to 10,500 kilojoules or 10,500,000 joules. In one day there are 24 x 60 x 60 seconds = 86,400 seconds, so the average rate of energy consumption or power of the body is 121.5 joules/sec = 121.5 watts. Now this is normally used in activities, so if you were going to extract some electrical energy you would need more food, an extra 2000 kilocalories would give you 100 watts (assuming you can convert it), ie enough for a light bulb or some small appliances. It is much more likely that collecting thermal energy from body heat would be more feasible than energy from relatively weak electrical impulses in the body. Evidence of this phenomenon has already been seen by experiments designed to act as heat exchangers located in large convention sites in buildings. These exchangers then are used to heat other portions of the buildings as proof of recycling thermal energy.

To recap the answer is no. There is too little electrical energy and it is being used for control purposes. The thermal energy is too little also. 121.5 watts even at 100% efficiency is too little to be of use. Buy a solar panel. They are bad investments too, but they provide more then a human could.

Answer 3

Yes, our bodies naturally produce electromagnetic energy through the activity of our nerves and muscles. However, it is currently not feasible to harness this energy efficiently for practical purposes. External devices, like pacemakers, can help regulate the body's electromagnetic processes.

Answer 4

No. Human beings do not produce a measurable electric current under most circumstances. Even if they did you would still need a plug to convey that current.
