Controlled Tornadoes Create Renewable Energy

Source: http://discovermag tember/08-tornado- tech#.UguEttK1Hzk Tornadoes may be destructive, but even funnel clouds have a silver lining. Inspired by the process that creates natural twisters, electrical engineer Louis Michaud of Canada’s AVEtec Energy Corp. designed a nonpolluting source of swirling power he calls the Atmospheric Vortex Engine. The device can spin waste heat from power plants into usable energy. Instead of directing excess heat into conventional cooling towers that simply disperse it into the air, power plants could usher the heat into the hollow, open-topped tower of a vortex engine. A heat exchanger outside the tower transfers the extra heat (piped in as warm water) to ambient air. When this warmed air is directed into the tower at an angle, it encounters cooler air and produces a circular current. This current funnels air upward into a controlled twister whose low-pressure center draws more air into the tower, turning turbines at its base. These turbines drive a generator much like a wind turbine does, except, as Michaud says, “You’ve got more oomph to push it with.” Michaud has already demonstrated working models of the engine up to 15 feet across, but the real deal would measure 300 feet wide and half as tall, capable of producing tamed twisters that stretch nine miles high. When hooked up to the average 500-megawatt natural-gas or coal power plant, the vortex engine could produce an extra 200 megawatts of energy just by putting the excess heat to use. At a cost of less than 3 cents per kilowatt-hour, tornado energy is cheaper than burning coal (which rings up at 4 or 5 cents per kwh) and produces no additional greenhouse gases. The vortex engine could also run on heat sources other than power plants. “You’ve got to have warm air, and you’ve got to have spin,” Michaud says. Solar heat or warm ocean waters fit the bill. “If there’s enough energy in warm seawater to produce a hurricane,” Michaud says, “there’s enough energy to run a vortex engine.”  (Aug 13, 2013 | post #1)

http://www.authors tion/scarlettwilli ams01-1813230-1580 -97-2003/ Build a Small-Scale Ethanol Fuel Plant The search for alternative fuel sources has led to the development of ethanol, a gasoline substitute, but large-scale production of corn-based ethanol is controversial and it threatens the world's food supply. In Alcohol Fuel: A Guide to Small-Scale Ethanol (New Society Publishing, 2009), Richard Freudenberger gives readers all the information they need create a small-scale ethanol plant. In this excerpt from Chapter 4, he covers all the production aspects a would-be alcohol producer needs to consider. Ideally, your ethanol plant would be part of a farm or market-growing venture, for two reasons. First, as a grower you’d already have a familiarity with the day-to-day practices that agriculture entails. This includes working within a routine, searching for markets, dealing with equipment in both fair and inclement weather, and quite importantly, improvising when necessary to keep things running smoothly. As anyone who has worked the land can tell you, the most successful farmers are well-rounded Renaissance people who can roll with the punches and take things in stride. Second, a working farm provides a ready-made outlet for the manufactured fuel and its by-products. Most any internal-combustio n engine or heating appliances can be adapted to run on alcohol — this inventory includes tractors, trucks, pumps, generators, burners and furnaces — and the residual material from mash production contains enough nutrient to supplement normal livestock feed. If agriculture is not in your background, it’s still possible to manufacture alcohol, even economically, provided you have a reliable source of raw material, or feedstock. There are many viable candidates for ethanol production, including both sugar and starch crops. Residues from canning and juicing operations, even far from the farm, are also distinct possibilities. Realistically, it would be difficult to carry on much more than an experimental venture in a confined space such a suburban backyard, but it’s still possible. Ideally, a rural setting or a location where there’s room to expand and function without interference would be the better choice. Sourcing Raw Materials Finding a reliable and consistent source for feedstock material can be a real challenge. Chapter 5 will address the distinction between sugar crops such as cane, sugar beets and fruit juices and starch-based crops such as corn, sorghum, grains and potatoes. (Visit our online store to buy the entire book.) For now, it’s enough to say that certain plants produce more starch or sugar per ton or per acre than others, and given the right cost, crops with more concentrated nutrients are the best choice. To complicate matters, though, is the fact that the equipment needed to process the raw material varies by crop. Grain-grinding machinery is quite a bit different from the extractive equipment used to process sugar beets. Unless you can cultivate a reliable source of feedstock, it would be unwise to invest in any specific equipment. Consider, instead, renting (or leasing) that equipment if possible, or look into using the services of a local co-op. If you live in a rural community where processing and packing houses exist, you may find that reclaiming surplus and spoilage from these operations makes the best economic sense. Approached properly, most cooperatives and private processing facilities should be willing to negotiate an attractive arrangement — a deal, if you will — that would allow you to test the value of their spoilage as a feedstock, subject to performance results over a specific period of time.

Jakarta Crown Capital Eco Management: Environmental Scam ...

Biodiesel's Big Comeback Darling of the mid-2000s, still beloved by its many fans — biodiesel is increasingly a key to delivering advanced biofuels volumes now — and even more so between now and 2022. Presentations by NBB CEO Joe Jobe and REG CEO Daniel Oh at ABLC 2013 explained the how and why. In the excitement over cellulosic biofuels and drop-ins, it is easy to forget that the backbone of advanced biofuels in the US and around he world is biodiesel — and not the least of the many services that biodiesel has rendered is enabling the biofuels industry to make up for a shortfall in the production of cellulosic biofuels, by over-delivering on the targets for biomass-based diesel. While the boom years of biodiesel capacity building are long over, the sector has been going through a renaissance in the past two years, which was plainly in evidence from the bullish outlooks presented at the Advanced Biofuels Leadership Conference by National Biodiesel Board CEO Joe Jobe, and Renewable Energy Group [NASD:REGI] CEO Dan Oh. Jobe presented on the first morning of ABLC, alongside the chiefs of the other four trade associations, and while the theme of stewardship and sustainability was a common one – touching on issues such as the protection of RFS2 and RIN fraud — the growth scenarios he presented were the most aggressive and the record of growth delivered in the past year was the most impressive. Meeting RFS2 targets He discussed the 5×15 initiative — converting 5 percent of the US diesel market to biodiesel by 2015, and said that the industry was well on the way to delivering on that goal. The longer-term? The biodiesel industry is aiming for 10×22 — or 10 percent of the US diesel market, just north of 5 billion gallons, by the last year of the current Renewable Fuel Standard. That would deliver nearly 8 billion gallons towards the 2022 RFS obligation, because biodiesel gallons count for 1.5 ethanol-equivalent gallons because of their higher energy density. Were US biobutanol production able to reach its current blend wall in the same period through conversion of the ethanol fleet — replacing 16 percent of the US gasoline market, or roughly 18 billion gallons of projected 2022 demand — that would total 23.4 billion ethanol-equivalent gallons, and between this total and biodiesel, the US would need just 4.6 billion gallons of ethanol-equivalent drop-in fuels to meet its 2022 obligation. Without requiring E15 ethanol blending or putting additional infrastructure requirements on auto manufacturers or the supply system. That 4.6 billion gallons of ethanol-equivalent fuel would translate to 2,8 billion gallons of actual operating drop-in fuel capacity — and global capacity is over 21 billion gallons today. In short, RFS2 presents reachable targets — but biodiesel is key to accomplishing them. With such a rosy picture of growth — it’s astonishing that in the entire debate on food vs. fuel there is hardly ever a word about biodiesel — and ranchers, poultry farmers and food manufacturers are never seen targeting biodiesel for the kind of all-out assault that is seen with corn ethanol. Over to REG The reason was plain from REG CEO Dan Oh’s presentation at ABLC – looking at how biodiesel is highly complimentary to the food and ranching industries — and supports a “food, then fuel” production system. More on Renewable Energy Group First, some background on REG for those less familiar. The company has increased sales from $132 million in 2009 to $1.015 billion last year, and EBITDA rose from a 2009 loss of $12M to last year’s $188M. The company has increased biodiesel sales to 188 million gallons last year, and now owns 227 million gallons of capacity — and has another 150 million in development or construction.
