How to eliminate China’s air quality problem.

Tags

The Lurtz Cycle, operating on waste heat, could eliminate China’s air quality problems. By providing electricity 24/7/365 from small site, shallow, geothermal locations, A massively redundant local electrical grid, that does not send polluting chemicals into the air, can be established with minimum capital expenditures.

The Lurtz Cycle can provide electricity to the general public without the need for giant power plants. Distributed energy production, from thermal solar, shallow geothermal, industrial waste heat, is the solution to the World’s energy problem.

What is Low Temperature Heat?

Low temperature heat sources are available anywhere that there is a temperature difference of about 30C or 40F between the heat source and the heat sink. Examples of low temperature heat sources are as follows: a) 30F Sea water {heat sink} and 70F {heat source} temperatures. b) 30F Sea water {heat source} and -10F {heat sink} temperatures. c) Geothermal temperature of 50F {heat source} and 10F {heat sink} temperatures. d) Geothermal temperature of 50F {heat sink} and 90F {heat source} temperatures. It is easy to see that Solar thermal can provide the heat source almost anywhere. Even starting a small fire will provide the energy for the heat source. Note that energy for the Lurtz Cycle comes from both gravity and from the heat source. In addition, think how easy it is to store “low temperature heat”. A foam insulated “swimming pool” size heat source at 90F [with a geothermal heat sink] can store heat for days and can produce 24kwh of electricity per day.

Waste Heat Recovery from Power Plants

In the Power Plant Cycle, after all of the energy has been extracted and converted to electricity, the steam must be converted back into water. This is the purpose of the Power Plant cooling systems. This heat is typically dumped into rivers, lakes, or waste heat reservoirs.

Instead of dumping the heat into the environment, this “low temperature heat” can be used to generate electricity at high efficiency via the Lurtz Cycle.

Why hasn’t this been done before? New ideas take time to be understood and implemented.
