Semiconductor Fabrication

It is nice to see that somebody else is finally getting it.

While some people are pushing for large infrastructures to increase the amount of energy available, the "GREEN" technologies are not living to their promises when you take into account the subsidies and the total environment impact including production.

The only technique that is proven is the nature's way! Use the wastes from one organism to feed others. It starts with plants converting solar energy into tissues that are eaten by others. Their wastes are also consumed by animals, mushrooms, bacterias... Nothing goes un-used until it has been degraded back to basic elements that plants can pump up with solar energy to start over again.

Similarly, every process has wasted energy and products. I we were to recuperate half of those wasts, we would not need those new electric generators (oil, gas, coal, nuclear, hydro, wind, tide, or sun powered).

Here is a real example: Some guy built a greenhouse up North to grow tomatoes all year long. This normally requires thens of thousands of dollars of heating capacity in the winter. Being brighter than the average guy, he located his farm just next to a paper mill that was rejecting tons or warm water to the river. He used this wasted heat to heat up the green houses in the winter.

Unfortunately the mill closed but the guy had many years of almost free energy and produced tons of tomatoes out of wasted energy. It also reduced the heating of the river and probably reduced the impact of the mill.

That is a good example of the techniques that have to be developed. To be successful, these have to be simple. Once that you add too much equipment, the project fails.

Another example is that many people in Canada heat up their swimming pool and spa in the summer. They also have a separate AC unit to cool down their house. This is a total waste of energy. I do the same but I use the one heat-pump to do both. This way, I heat my pool with the heat rejected from my house. The AC is also more efficient because it transfers the heat to cool water instead of the warm outside air. The pool is the equivalent of a cooling tower to my AC and the AC is a heater to my pool. This is a win-win situation. It increases my personal comfort while reducing my energy consumption. The cost was less than $1000 to modify my heat-pump. Less than most people spend on their pool heater.

What are your ideas to use wasted energy?
