Tucker...you be smoking dope!
I don’t have a problem with coal, except that it releases more radiation (from trace elements of radium) than nuclear.
I don’t have a problem with nuclear. I don’t think highly of oil because it gives too much money to our enemies in Venezuela, and the Middle East. The Fischer Tropp process converts coal to usable oil (with a higher aromatic content) at reasonable rates, but there is no sense in that process if we are not willing to drill. Coal is environmentally more invasive and expensive per BTU than oil.
There is little need to conserve energy resources. By the time we use up the oil, Fischer Tropp will be there with more fuel at a slightly higher cost. By the time that coal and Fischer Tropp oil prices go up, we will have derived economical ways to use nuclear fission, and eventually nuclear fusion.
Thanks for this one!
Nuclear fission is already economical!
I agree. You can tell what makes sense by the number of lawyers and eco-crazies that protest it. The more nuts and vultures, the more sure you are that it is a good idea.
Good read. Worth getting to this gem on the last line.

Because existing coal-fired power plants vary in size and electrical output, to calculate the annual coal consumption of these facilities, assume that the typical plant has an electrical output of 1000 MW. Existing coal-fired plants of this capacity annually burn about 4 million tons of coal each year. Further, considering that in 1982 about 616 million short tons of coal was burned in the U.S. (from 833 million short tons mined, or 74%), the number of typical coal-fired plants necessary to consume this quantity of coal is 154. Using these data, the releases of radioactive materials per typical plant can be calculated for any year. For the year 1982, assuming coal contains uranium and thorium concentrations of 1.3 ppm and 3.2 ppm, respectively, each typical plant released 5.2 tons of uranium (containing 74 pounds of U-235) and 12.8 tons of thorium that year. Total U.S. releases in 1982 (from 154 typical plants) amounted to 801 tons of uranium (containing 11,371 pounds of U-235) and 1971 tons of thorium. These figures account for only 74% of releases from combustion of coal from all sources. Releases in 1982 from worldwide combustion of 2800 million tons of coal totaled 3640 tons of uranium (containing 51,700 pounds of U-235) and 8960 tons of thorium. The main sources of radiation released from coal combustion include not only uranium and thorium but also daughter products produced by the decay of these isotopes, such as radium, radon, polonium, bismuth, and lead. Although not a decay product, naturally occurring radioactive K-40 is also a significant contributor. According to the National Council on Radiation Protection and Measurements (NCRP), the average radioactivity per short ton of coal is 17,100 millicuries/4,000,000 tons, or 0.00427 millicuries/ton. This figure can be used to calculate the average expected radioactivity release from coal combustion. For 1982 the total release of radioactivity from 154 typical coal plants in the U.S. was, therefore, 2,630,230 millicuries. Thus, by combining U.S. coal combustion from 1937 (440 million tons) through 1987 (661 million tons) with an estimated total in the year 2040 (2516 million tons), the total expected U.S. radioactivity release to the environment by 2040 can be determined. That total comes from the expected combustion of 111,716 million tons of coal with the release of 477,027,320 millicuries in the U.S. Global releases of radioactivity from the predicted combustion of 637,409 million tons of coal would be 2,721,736,430 millicuries.

Not for transportation energy, which is the point of Fischer-Tropsch oil.
I recently visited a coal fired plant and one feature I noted they used to cut down pollutants was a constant fine spray of sugar water through the gases escaping the stacks. Supposedly brought down the level of said pollutants / minerals like mercury etc , the parts per million (ppm), to very very low amounts.

Obama will continue to push windmills and solar plants, kill off coal as a source of power and make electricity almost unaffordable all in the name of saving the planet from non existent global warming. I fully expect that many of us will in the near future be shivering or sweltering in our darkened homes because we cannot afford our electric bills.
It's got to go somewhere...
An environmental disaster of epic proportions just happened in Tennessee. Monday night 2.6 million cubic yards (the equivalent of 525.2 million gallons, 48 times more than the Exxon Valdez spill by volume) of coal ash sludge broke through a dike of a 40-acre holding pond at TVAs Kingston coal-fired power plant covering 400 acres up to six feet deep, damaging 12 homes and wrecking a train.
According to the EPA the cleanup will take at least several weeks, but could take years. Officials also said that the magnitude of this spill is such that the entire area could be declared a federal superfund site.
Toxic Sludge Got Into Tributary of Chattanooga Water Supply
Apart from the immediate physical damage, the issue is what toxic substances are in that sludge: Mercury, arsenic, lead, beryllium, cadmium. Though officials said the amounts of these poisons in the sludge could not be determined on Monday, they could (at the mild end) irritate skin or trigger allergies or (longer term) cause cancer or neurological problems.
This toxic sludge got into the Emory River, a tributary of the Clinch and Tennessee Rivers: The water supply for Chattanooga, Tennessee as well as millions of people living downstream in Alabama, Tennessee and Kentucky. TVA says that as yet the spill (which they are characterizing as a mudslide or landslide, but frankly it's still toxic...) has not affected the water quality in the Emory River.
Thanks for the ping!
Mini nuclear power plants, for a mere $25 million, for 25-30 megawatts, are already available.
Start putting many of these now where a single plant can serve a single industrial requirement, watch the growth and use of the technology move to eliminating the need for “the grid” to serve remote areas at all and in the first decade of their adoption we would probably eliminate the need for massive additions of massive (and massively expensive) power plants on “the grid”.
The grid will always represent an element of “systemic” risk. Mini nuc plant technology could make “the grid” simply the “backup” power source, with energy being produced largely where ever it is needed, at a scale it is needed, locally.

Here is a good USGS fact sheet: http://pubs.usgs.gov/fs/1997/fs163-97/FS-163-97.html
Virtually 100 percent of the radon gas present in feed coal is transferred to the gas phase and is lost in stack emissions. In con-trast, less volatile elements such as thorium, uranium, and the majority of their decay products are almost entirely retained in the solid combustion wastes. Modern power plants can recover greater than 99.5 percent of the solid combustion wastes. The average ash yield of coal burned in the United States is approximately 10 weight percent. Therefore, the concentration of most radioactive elements in solid combustion wastes will be approximately 10 times the concentration in the original coal.
The result of this terrible concentration of radioactivity in the fly ash? Well, it raises the level of radioactivity to about the same level as is found in common shale, granite, or black shale. How terrible is that!

But what about all that dangerous radon from coal combustion! Look at where release of radon into the environment from coal burning ranks in the table here:
TABLE 4
| Sources of Global Atmospheric Radon | |
| Source | (million Ci per year) |
| Emanation from soil | 2000 |
| Ground water (potential) | 500 |
| Emanation from oceans | 30 |
| Phosphate residues | 3 |
| Uranium mill tailings | 2 |
| Coal residues | 0.02 |
| Natural gas | 0.01 |
| Coal combustion | 0.0009 |
| Human Exhalation | 0.00001 |
Thank you!
Your post shows how mimimal radiation emission is for nuclear.
We normally don’t think of burning coal as a radiation emitting process, because the amounts are so very small. Radiation emitted per BTU of nuclear power plants is even less.
In addition to “Drill Here, Drill Now” for oil related power, we should add, for nuclear and coal: “Build Here, Build Now” and “Dig Here, Dig Now”.
Thanks for the ping.
