Most big projects are funded by governments. That means that supply and demand, labor costs, and regulations do not apply. Nothing applies to a government project. It's a racket.......believe me, I've done enough of them to know.
But you are missing the whole point. I'm talking about science, not politics.
At the present time, we have to mine and extract fuel, to power our world. Many expert idiots think that extracting and using fossil fuels is a danger to our environment.
My interest is not saving the world. My interest is the personel cost of the fuel.
The price of that fuel is not consumer based......it is politically set. By idiots. Not by supply and demand, but by politicians.....to save the planet for the children.
The majority of my personal fuel costs is heating and cooling. Probably about 70%.
That energy, that fuel, is used to maintain a temperature difference, between the ambient air temp and my inside air temp.
By using passive IR radiation, we can maintain the temp difference without burning fuel. NOT ONLY THAT, but the heat that is expelled, to sent into space, not to another area or media of this planet. Right now, when I expel the excess temp into the air. Warming the air. And when that hotter air, goes into someone's else house, it will take more energy to cool that warmer air.
With IR radiation, that cycle is broken. Just one of the methods that this is done, is by micrometer size glass beads. It was found that the size, shape and refractive index of the glass used, set or tuned, the absorption spectrum and the radiated spectrum of the bead. It absorbs all the light and near IR from the sun, and re-radiates( just like a radio repeater) the energy at 10 u-meters. This is a mid IR slot in the atmosphere.
These beads can be applied in paint or a spray on clear film.
Ok, ok, but what about a desert region? Have you ever seen a sand spreader? We used them here for icy roads. If we crush that sand, so that a proportion of the sand is the right size, for that type of sand, we can cool regions in the middle of the desert. We do not have to cool the whole desert. Just a region of it. The cool regions will bring the oceans air and humidity in.
We could also cool regions of air, by falling the right size sand thru the air.
We can crush sand to any size we want, very cheaply, and with demand, even cheaper, if we can keep the politicians and our so-called experts, out of it.
Even if we had to use refined manufactured glass, the saving costs should change the way we live.
This is the way to compete, with fossil fuels. Enslavement and poverty is not necessary to save the world for the children.
But watching the way the experts handled a virus, they will probably cause more harm than good.
All the experts really showed their phony asses, with this virus.
And one other thing. Why haven't the environmentalists, been promoting these solutions for the last five years?
Do they really want a solution? Is a solution even needed?
Fanatics always insist on one solution.
