That's right, if the airflow at your air outlet is exhausted, then in theory it can be used to generate electricity. If you use a fan to blow air to generate electricity, it won't work, because with. with each transformation of energy there is a loss.
In addition, because the density of air is very low, the energy carried by the wind per unit volume is very low. Therefore, to obtain relatively large power, a large diameter wind turbine must be used. Only in this way can benefits be produced, and the energy conversion limit of wind turbines is only 0.59, less than 0.6. Generally, large wind turbines are actually 0.5, so wind power generation must be increased to gain benefits.
There are many types of electricity generation, some will produce pollution and others will not. Thermal energyique will pollute the atmosphere, but hydroelectric power, nuclear power, solar power, wind power and tidal power will not pollute the atmosphere. atmosphere.
Tap water purification is a filtration method that does not produce harmful gases and therefore does not pollute the atmosphere.
