We don't innovate with energy because it is too cheap...but we will all be innovating big time sooner or later......not starving in the dark.
“Leibig’s Law” states that growth in a system is controlled not by the total of resources available, but by the scarcest resource (limiting factor). How does this apply energy production? I have about 7.20E+03 pounds of lead in my home PV system. Global production of lead is about 3.88E+06 tonnes per year. The 1.30E+08 homes in the US would require 9.36E+11 pounds (4.25E+08 tonnes) of lead every eight or so years. For alternate energy storage in homes, the US alone would need 100 times the current global production of lead – six times the global reserves of lead – just for US home electrical storage (that number DOES NOT include transportation or business)! Therefore, we know that it’s literally impossible for alternative energy to replace fossil fuels. It’s literally true that “peak oil” is equivalent to “peak everything.” More on scarce minerals at http://www.theoildrum.com/node/5559 http://europe.theoildrum.com/node/5239
I send your post to my engineering friend, Here are his comments:
This guy is living the standard brainless clueless USA energy hog existence with 7000 lb. worth of batteries. In contrast Barbara Kerr (Kerr-Cole Sustainable Living Center) gets by on 480 lb. and I live happily with 240 lb. of batteries. Nonetheless he has the right idea regarding lead. According to globalleadnet.com STRONG>/ STRONG> /FONT> STRONG>/ STRONG> /file_download/17/5.pdf the US production was from 477,000 metric tonnes of 65% ore concentrate, which works out to 680,000,000 lb. in primary lead (not from recycling) sources (mining) in 1991. This is enough to supply 1000 lb of batteries to 680,000 new installations. Presumably existing installations will recycle lead, and therefore will neither add nor subtract from the lead supply. This guy forgot that lead is not consumed in batteries in 8 years; it is nearly 100% recyclable. He forgets that there are other battery technologies that will come into the mix: nickel-metal-hydride (my Prius for example) and lithium ion (the coming plug-in Prius for example). The future probably lies in running your house partially off the car battery using grid-tie EV technology - and learning to live with severe electrical energy rationing (by today's standards). This guy is also ignorant of compressed air automotive technology. And of power grid storage options such as hydrogen, ammonia (a much more practical offshoot of hydrogen), compressed air, flywheels and pumped hydro for on-demand electricity production. Not everybody needs batteries in a renewable, alternative technology. One can use the grid via net metering to store what one generates, or just buy the alternative juice from the utility.
Most important, he is neglecting geothermal energy which is a base load technology (runs 24/7 and therefore does not require any storage whatsoever). I am right now at one of the most advanced geothermal plants in the world, Chena Hot Springs near Fairbanks. The maverick entrepreneur owner of this spa put in a cutting edge power plant a three years ago on his own nickel (well 2.5 megabucks, actually) for 1/5 the cost of conventional technology, mainly by modifying a standard industrial chiller to operate in reverse using mostly off-the shelf components (with concomitant economies of scale using reliable mature design equipment that has been in production for decades). He has cut his electrical energy cost by $500,000 dollars a year because he has replaced diesel ($0.50 per kWh operating cost) with geo ($0.02 per kWh operating cost). The key innovation is that it runs off low relatively low temperature hot water, making it operable from deep earth heated water from depleted oil wells. This the "geothermal anywhere" (GA) concept. He is now going into the business of putting 200 kW mobile power plants on a semi trailers and leasing them out to wherever waste heat or easy geothermal is available. The first two mobile units are supplying power to this community and my computer right now as they undergo pre-delivery testing (they are temporarily replacing the on-site power plant). Very soon they will take a 6000 mile trip to Florida to run on oil well waste heat.
The installed plant here produces twice the power the community needs (for emergency backup redundancy for service down-time or failure of one of the generators). So he just put in a hydrogen electrolysis plant to transport "stranded" excess energy capacity to market. Waste heat warms four-season greenhouses (the tomato plants are 14 months old and producing like gangbusters). He has all the lighting he wants to keep the grow lights on in the winter 24/7, 100 miles from the arctic circle. He plans to become self-sufficient in food.
Interesting, huh? You might think about relocating to a community with hot spring or depleted oil well. There may be a future in it.
