energy is a worldwide shortage, oil prices rise, energy companies take from the consumer. At the same time caused the man to climate catastrophe, so it can not be too much demands that the man himself in person also used for energy. But how can man be used as an energy source? Can one man in the future as a primary energy source "abuse"? If so, how the proportionality between the budget and for example a commercial building, vo is run thousands of people?
Who does not know, watches, without the battery, ECG devices that work without power cable. How do you want? It is here only the electrical voltage from the difference between body and ambient temperatures generated. A small but important step for the future.
yet decentralized energy could be derived, one could tap into the energy of the people - which is also made in some places already. The disco "WATT in Rotterdam, for example, uses the energy of the stamping feet of dancers. A third of the electricity consumed in the restaurant to be built Sun Many people create in a room but without the sweaty dance energy. Even in sleep, man is active and emits heat.
Man, the temperature inside his body kept constant at 37 degrees Celsius. This exception is due to its metabolism a constant heat source with an average power of increased physical activity, of about 100 watts. This heat must be discharged to the environment, mostly as heat radiation, and possibly as evaporative heat through perspiration. The final heat loss or heat gain of a body resulting from the difference of its own radiation and radiation absorbed his surroundings. On his body temperature of 37 ° beams, man - are based on a body surface area of 2m2-ever about 1050 watts heat. At the same time it receives thermal radiation according to the temperature of surrounding air, eg at an air temperature of 29 ° in altitude of 950 watts. At this temperature, net radiation corresponds exactly to the human heat product. The body temperature remains constant, this through without the need for thermal protective clothing. 
In our climate, and with adequate clothing, we have adjusted our heat-related well-being habitually at a room temperature of 20 °. At this temperature, we would be unclothed net emit about 200 watts, so cold very quickly. Through the thermal insulation of our clothes, we reduce the emission to the environment to the always-on 100 watts.
By this theory, would produce 250,000 people in a room that is 25 megawatts. This number of people are to run daily at the Stockholm train station. Thus, the Swedish State Property Management has discovered the man as an alternative energy source. The company will continue to heat up the body heat of the approximately 250,000 people, an office building. instead to direct the heat through windows to the outside, this will now be made available via the ventilation system. The heating costs of the office building which should be ready by 2010 near the station were so reduced by up to 20 percent. The concept is, therefore, the body heat of station visitors Warm water, which is then piped to the proposed office building. This is an old technology that is used in a new way. It is just water, pumps and pipes.
