Life After 40: Suppliers Anxious to Support Life Extension Initiatives forAging Nuclear Power Plants
As predicted by the American consulting firm International Nuclear, Inc. (iNi), mining companies are having difficulties meeting the increased demand for fuel by nuclear power plants, which produce approximately one sixth of the electricity used in the world today.
Chevrolet's Volt, a plug-in hybrid due out in November, will draw 8 kilowatt-hours of electricity from the grid to go 40 miles. (The Volt also has a gasoline engine; hence, it's a hybrid.)
The Leaf, which looks like an updated Nissan Versa, is powered by a lithium-ion battery that Nissan has developed. It takes about 16 hours to fully charge the battery using a 110-volt outlet, or about eight hours using a 240-volt outlet.
With a 24 kilowatt-hour (kWh) lithium-ion battery costing about $600 per kWh, the battery itself would cost about $14,000. [24 * 3413 = 81,912 BTU for 100 miles?]
Essential non-gas-wasting trip to mountain communities to the east of albuquerque to look for new solar/wind project and FOR SALE signs resulted in
The Chevy volt is reported to use 8 kWh to go 40 miles.
8 * 3414/ 40 is top is BTU/mile for Chevy volt.
9.224 * 114,000 / 287.4 is bottom BTU/mile for Honda CR-V.
But we must more than double the Chevy volt value because of the heat rate required to convert BTUs to kWhs.
Hydroelectric generation has the fourth largest share, nearly 6 percent.

Google Greening Server Farms with....Irrigation? Written by Matt James on 14/11/07
the greening of server farms roger allen
Under current efficiency trends, national energy consumption by servers and data centers could nearly double again in another five years (i.e., by 2011) to more than 100 billion kWh (Figure ES-1), representing a $7.4 billion annual electricity cost. The peak load on the power grid from 7 these servers and data centers is currently estimated to be approximately 7 gigawatts (GW), equivalent to the output of about 15 baseload power plants. If current trends continue, this demand would rise to 12 GW by 2011, which would require an additional 10 power plants.steve martin pnm covered contribution of refrigerated air conditioning and electronic devices to increasing electric load demand.
Although China has plenty of coal, there are several reasons the country cannot meet its energy demand with coal in the foreseeable future. The first is clear: environmental. But even if the cleanest coal technology were adopted, even if all dirty coal plants were replaced, and even though China has been adding one new coal-fired power plant per week, coal still cannot replace oil because virtually no oil is used for power generation and nothing but oil is used for transportation.

Lead locomotive engineer was asked what boiler pressure used.
Engineer responded that he liked to operate between 195-97 psi but never below 190 psi. He added that the pressure safety valve released at 199 psi. Boiler explosions happen.
Listen to them depart the station.The hissing you hear on Windows Media Player is steam released into the cylinders through a slide valve, we speculate. Engine aspirations are most pronounced as the slider reaches the middle.
Chug, chug.
Note that lead locomotive is putting on the steam while trailing locomotive is not.
Reason likely is that lead locomotive will return to Chama from Cumbres pass while trailing locomotive will proceed to Antonito, CO. The trailing locomotive needs to conserve coal. BTUs, of course.
That coal contains between about 8,600-10,000 BTUs per pound. Coking coal up to about 15,000.

Mr GogginAs far a wind farms go, is Fast Neutron's statement
From actual experience, wind farms produce 1.2 watts per square meter. Solar Thermal and Photovoltaic methods capture 5 to 6 watts per square meter. There is no economy of size in either technology. Dividing the watts you need by those values gives the land area in square meters needed to produce the juice. The numbers are astronomical

IF Fast Neutron is wrong about wind farms, then what is the correct value?
Thanks in advance.

Subject: RE: fast neutron on solar and wind electric output
Bill, the numbers I like to use are from Vaclav Smil in his 21st Century Energy article.
He says solar PV is 20 W per square meter of peak power. He says wind and water power are below 10 W/m2. Biomass is well below 1 W/m2.

Subject: RE: W/m2 vs kWh
Electricity production (output, generation) must be measured in energy units, that is in joules (one joule being one watt-second, and one watt-hour being 3,600 J and one kWh being 3.6 MJ) or in the infernal American system inherited from the Brits, BTU). Installed capacity (power) comes in power units that is in watts (J/s) or horsepower (1 ho=~745 W). Wind people rarely cite the production (generation) figures because those depend obviously on the load (capacity) factor, which for wind is anywhere between 20-35%. They prefer to quote installed (peak) power capacities instead, thus deliberately exaggerating any installation achievements as, say, 1 MW in wind turbine is not 1 MW in gas turbines or steam turbines. Power density calculation are done as the first approximations for rated (installed, peak) capacities because there can be no uniform load factor to apply. The same problem arises with hydro stations: a station in a dry years may have load factor of 20%, in a very rainy year 60%.

Subject: W/m2 vs kWh
Hello professor Smil,
Are the W/m2 you reference below peak power?
Reason I ask is that some in the electric energy field apparently prefer to measure electric output in terms of kWh instead of peak power.
Thank you for your previous response.

Subject: RE: btu/pound of uranium
It gets a little complex, but on the issue of 900,000,000 vs 35,000,000,000. The larger number is just for U235. A typical power reactor is mostly U238. The U235 is about 2.5% of the original fuel load. This may explain the difference in the numbers. Also, all reactors breed a bit so some of the U238 is changed to plutonium (Pu239) and some of that fissions to provide a significant percentage of the energy from a typical power reactor.
Hope this helps.

Subject: Kilowatt-hour (kWh) - A kilowatt-hour is the quantity of energy delivered when power flows at the rate of one kilowatt for one hour. It is equal to 3,412 Btu.How is 3,412 Btu computed?
I became more interested in energy in about 2006. There are differences between interest, expertise, and ability.
Hopefully here is an area of my expertise. And ability too.

Insolation is the rate of solar energy arriving on a specific flat surface perpendicular to the line of the sun. At sea level, the least possible loss is 29 to 30 percent. The maximum possible insolation is therefore about 70 to 71 percent of the solar constant., or about 320 BTU per hour per square foot. No solar collector, regardless of shape or design can deliver more than this maximum possible value, without energy input from some other source.Banking on Green Energy December 18, 2009.

Iran defies world with plan for ten new nuclear sites
Offshore wind: Comprehensive initial study is critical
The Nimitz-class supercarriers, a line of nuclear-powered
aircraft carriers in service with the United States Navy, are the largest
capital ships in the world, and are considered to be a hallmark in the
superpower status of the United States of America.[1] These aircraft carriers
are numbered with consecutive hull numbers starting with CVN-68. The letters
CVN denote the type of ship: "CV" is the hull classification symbol for
aircraft carriers, and "N" indicates nuclear-powered propulsion. The number
after the CVN means that this is the 68th "CV", or large aircraft carrier.
Aren't BTUs the focus of all these matters? 1kWhr = 3412.14163 BTU. Overall, the average US water evaporation at thermoelectric plants is 0.47 gallons/kWh.
Then there is the reverse. HEAT RATE. Heat rates vary from over 29,000 [geothermal] to slightly over 7,000 [2x1 combined cycle natural gas] BTU per kWh.
There is a substantial BTU loss converting heat to electricity then back to heat. The second law of thermodyamics covers this.
Coal ash, CO2, CO, SO2, mercury, cadmium, ... and radiation!Pollutants such as sulfur dioxide, nitrogen oxide and particulate matter from 406 coal-fired power plants in the country made up $62 billion in damage, or an average of 3.2 cents for every kilowatt-hour produced, the report said.Approaching Cumbres pass on Saturday October 10, 2009.
