I like solar too. I have it and it saves me about $400.00/mo in electricity. It was 120 degrees yesterday and it was 72 degrees inside my house.
A solar wall? Has anybody figured out how much the power transmission lines are going to cost? The panels need to face south-towards Mexico. Have they figured out how much damage the vandalism is going to cost?
Coal ash contains cadmium. It's a carcinogen. My spouse lost a kidney to renal cell carcinoma due to transdermal exposure to cadmium. We had to get a water conditioner and RO water system to mitigate exposure to toxic metals.
You want coal? I don't have a problem. Go for it.
I don't provide links because too many people are finicky regarding sources.
I kindly suggest you google "map of cancer incidence in the US". Take your pick.
If you put them on top of the wall as I have described you will not be able to see them very well. I would imagine vandislim is going to be on the top of the list for things to consider for design.
It's elevated above dirt but it's not that far off.
Oh come on.... If the coal contains high levels of sulfur—as does most coal from the eastern US—it must be cleaned and refined before it’s burned in a power plant. This process involves crushing and washing the coal to remove waste materials. The purified coal is then transported to its final destination, leaving behind coal slurry, a watery waste that contains arsenic, mercury, chromium, cadmium, and other heavy metals. As much as 50 percent of pre-processed coal materials can end up as highly toxic waste.

The only issue here is when the impoundment dam breaks, rare occurrence but unacceptable nonetheless.
The industry I'm involved with the smallest sizes are used for water filter <gasp>. Anthracite fractures into odd sized shapes, it's ideal for replacement of sand filters because they last longer.
Price is higher, but prices are plummeting rapidly. should be cheaper than coal within our lifetime

The cost per watt is only one issue and in the grand scheme of things not the biggest issue. It's the storage and capacity issue.
Soalr and wind are 100% dependent on generation from coal, natural gas, hydro and nuclear. A lot of what you pay for electric is the capital investment in those plants. You cannot eliminate that capital investment and the less they run the more it cost for the electric they produce.

How long will coal last and how long will the sun last? Also storage isn't a problem with the powerwall anymore. So don't throw that argument up.

Sort of. The highest usage of power occurs during extremely hot days. I think ALL of these technologies ave a place at the table. But coal....is losing to natural gas for its place.

natural gas is so much better than coal. coal sucks.

The amount of fossil fuels in this country is so vast it's irrelevant argument because the technology that can replace it will supersede it before the supply runs out. Likely geothermal or fusion.

How many solar panels and batteries do you need for the following scenario.
It's 0 degrees out in the northeast, cloudy, no wind and utilities are hitting record demand at 7AM. It's going to be like that for the next two weeks.
When you are done calculating the cost of meeting this demand with solar arrays and batteries get back to me. You simply have no clue what you are talking about... batteries... LOL
