Free choices are good and facts help us make the best ones for our lifestyle. I don't much care for the government telling me I need to pay for someone else's solar panels. Nuclear, resonance, local radon (OK BTW), lawsuits, etc. off point. Nothing wrong with making an assumption and working facts in to support it (or test its validity). Nothing wrong with establishing facts and making a conclusion from them. Not sure who sets the rules of sequence here. And that one is better than the other. Here's a few "facts" to consider.
The "Rules" are the scientific process. A person observes...then makes a hypothesis (assumptions is your word) and TESTS THEM. The hypothesis becomes increasingly PROBABLE as the facts come in.
By the way...are we counting now? Does truth get discovered in volume?
1) The photo of the Ames generating station shows a small hydro plant that is very much representative of how one form of energy is converted to electricity and transmitted to the consumption point. The AC generator's basic design shown in the photo is still used today. The transformers used there are also what's used today. Very little has changed. Bearing losses, hysteresis, eddy currents, etc. are cherry picks off point.
Actually the water-generated ancient AC generator was entirely "off-point" to the discussion of Solar Panels. Making correct references to off-point facts doesn't buttress a point of view.
2) The efficiency of that old equipment to including a 10% estimated transmission loss is well above any solar panel, controller and inverter scheme. Plus 3 phase power is available at the generator terminals. An important factor when large amounts of power need to be delivered over a distance.
Interesting! I will consider using the water-fall in my back yard to
from now on power my house...thank you very much for this sensational new idea!
3) Generators, transformers, turbines and transmission wires don't emit CO2. It's the CO2 byproduct (burning gas & coal) of the heat source that is of concern in power plants. Not a factor in nuclear, hydro, geothermal or tidal. Those have other issues. If that heat source can be replaced with one emitting less CO2, that's an improvement.
"...and other issues..."
4) The "old fashioned" generating equipment is very efficient, reliable and cost effective. Has a proven track record too. Can be used equally well in solar, nuclear and hydro power generation systems.
You continue to go off-topic with GENERATING EQUIPMENT and TRANSFORMERS, etc. And, you're obfuscating the discussion by combining A GENERATOR with a system that GENERATES electricity.
5) Solar is and will continue to be a part of supplying the world's growing energy needs. Whether this is best accomplished by single consumer voltaic home systems, a centralized approach like Solar One or both remains to be seen.
It's being seen already...it obviously will be BOTH. No on is going to tear down a City for mirror-arrays. But, open land SOMETIMES can run multiple purposes; nothing to stop developments UNDER those mirrors.
6) Currently government subsidies are required to make consumer solar systems affordable and competitive with traditional forms of electricity.
So...finally some GOOD comes from Government, eh?
7) Solar panels must be installed on roofs in those areas where property isn't available around the building. Roof exposure other than south facing will reduce capture.
Really? I'll tell my two neighbors on both sides that, since we both have 3' off-sets from our property lines by City permits for ANY constructions whatsoever. They keep asking me about my zero power bills...I think it must be because they really want to SUE me?!
8) Solar tracking mechanisms aren't practical for home roof installations. They are practical for mirrors like those used in Solar One.
That didn't stop YOU from putting up panels ON A FLAT ROOF. I could just as well say that a fixed tilt for panels is MORE EFFICIENT; but we both know that, and it makes no difference to what we want to happen.
9) Sunlight needs to fall on a solar panel at right angles for maximum collection. A difficult/expensive problem to solve daily and seasonally.
10) Solar doesn't work at night so some supplemental power source will always be required. Or storage device to cover demand when the sun isn't shining. Or on heavily overcast days when output is below demand.
That is true...as well as a lot of people sleeping at night. But, power on grid can be distributed...and sometimes every bit helps. I'll bet people paying for their Air-Conditioner's high bills UNDER THE SUMMER SUN, might enjoy a bit of the Sun's power giving them relief.
10) Green energy is a myth. All forms of it have some sort of environmental impacts. It's important we know what these are over the short and long terms. Also how these impacts are affected by demand(s).
And the jump to the foremost philosophical/political conclusion...and the gathering of details to fill in and buttress it.
No one here is going to change anyone's mind. You're invested in a home solar system and believe in its benefits. Your choice. And I'm glad these options are available to those wanting to buy into the technology.
I don't accept your phrasing "believe." I know; the figures that I keep accurately speak for themselves, as well as to my pocketbook.
My beef is when the government steps in and tells me I need to pay for it. Forcing money out of my wallet to support a solution I don't believe in.
And probably everyone here and elsewhere would have the same view...except that every conceivable category of acceptance and rejection of specific Government programs would radically be different than your own. Throwing the Baby out with the Bathwater is usually a bad thing. Unfortunately these things happen...but we don't want to bring in further politics on your Site...so, I won't go that direction.
Yes, I think solar can be used to reduce CO2. I just don't buy into the piece meal home array approach as practical for me. I prefer a centralized approach like Solar One less the voltaic panels.
Entirely your choice, on your own property, which is as it should be.
I also have environmental concerns about mass production of solar panels. Given arsenic, cadmium telluride, hexafluoroethane, lead, and polyvinyl fluoride are just some of the chemicals used to manufacture various types of them. But if they are made in China I guess that's OK. That part of the globe doesn't affect us.
No that's not OK. Nor is poisoning streams and rivers with coal ash and putting Scott Pruitt in as head of the EPA. But I'll stay away from politics.
I also find environmental pressure groups lobbying Washington with THEIR better way(s) both arrogant and misguided. That's fine up until they start climbing around in my wallet. A line is then crossed. If people want a solar system and believe in its benefits, just pay for it. Very simple. If it truly has value and is competitive then others will follow the lead by choice not force. I also don't think forcing the power companies to buy the energy back is a good idea.
Yeah...but the clear anger isn't really justified. You're beating up on Straw-men that in part you've created. And, you and I aren't paupers; we don't worry about where we'll sleep tonight or if our stomachs are full. There are far, far greater threats to our wallets (and our lives) than the environmental groups.
As for Tesla's later years, he did do experiments with transmitting power through the air. It created many concerns and didn't lead to any practical "through the air" power transmission systems. This point has nothing to do with the AC power inventions he gave the world which are still in global use today. Some good did come out his eccentric work, however. See below:
A patent battle between Tesla and Marconi went on for years. Marconi died in 1937. Tesla died in 1943 and six months after his death the US Supreme Court ruled that all of Marconiís radio patents were invalid and awarded the patents for radio to Tesla.
Tesla's story is a sad one. Few remember him and many don't even know his name. He died penniless in his NYC hotel and it took 3 days to discover the body. Certainly an unfitting end to a man that gave the world such great contributions. Every time you plug something into an AC outlet, remember Tesla's inventions made that possible.
No one's a total angel...he ran off with money scheduled for something else (not theft in the truest sense). But, you fixate on Tesla...he was a genius...he did important things...he made mistakes (like all of us/he was human).
