 Vertical Farm Operating We have been showing conceptual vertical farms for years, but in Suwon, South Korea they have one working and producing vegetables. It is a little three storey demonstration project in a nondescript building (image here), operating much like Dickson Despommier has described in his book, The Vertical Farm, right down to the airlocks and sterility he suggests is required. The main problem is light -- in particular, the fact that sunlight has to be replaced by LEDs. According to [agriculture researcher Stan] Cox's calculations, if you wanted to replace all of the wheat cultivation in the US for an entire year using vertical farming, you would need eight times the amount of electricity generated by all the power plants in the US over a single year -- and that's just for powering the lighting. Valcent NOTE: The above System uses electricity to make light. Valcent In that process: Valcent's VertiCrop™ offers a cost effective solution for crop production with significant operating and capital cost savings over field agriculture. It also increases returns by using only a fraction of the resources required for traditional agriculture. In trials the unit increased some crop yields by up to 20 times the normal production volume and only required 5% of the average water used in conventional growing conditions. The VertiCrop system grows plants in a suspended tray system moving on an overhead conveyor system. The system is designed to provide maximum sunlight and precisely correct nutrients to each plant. Ultraviolet light and filter systems exclude the need for herbicides and pesticides. Sophisticated control systems gain optimum growth performance through the correct misting of nutrients, the accurate balancing of PH and the delivery of the correct amount of heat, light and water. NOTE: The System is designed to provide maximum sunlight. Valcent Products Inc. (OTCBB: VCTZF) introduces its revolutionary VertiCrop high density vertical growth system, technology that provides a solution to rapidly increasing food costs caused by transportation/fuel costs spiraling upwards with the cost of oil. Note too: Algae Fuel Here is a quote: 18 gallons of oil per acre per year of corn 700 to 800 gallons of oil per acre per year with Palm/Palm oil 20,000 gallons of oil per acre per year of algae in an open pond Problems? Buy out Why wait?

Producing range anxiety What is the reasoning behind the decision to make an electric car that does not have an accurate fuel gauge? Countering range anxiety production But Tesla Motors is working on a fast-charging procedure that it says will charge the Model S to around 80 percent battery life in 45 minutes.

OrganicThe efficiency was rather impressive. At slower flow rates, the total energy content of the hydrogen was 36 percent of the energy input into the system in the form of acetate. At this flow rate, about 85 percent of the energy stored in the hydrogen came from the salt-fresh water difference. The bacteria took the remainder of the energy from the acetate, using it for their continued survival and growth. Pumping water through the system only accounted for about one percent of the energy cost. The bad news is that this highly efficient system requires an expensive, platinum-based cathode. The authors showed that it’s possible to use a cheaper, Molybdenum-based cathode, but efficiencies dropped. The authors suggest that it might be possible to find a cheap material that works well with this system but, as of their publication, they’ve not identified one.

Solar Payback timeNow a U.K. utility company has released data detailing how owning an electric car could reduce the payback time on solar panels to under 5 years. If a solar panel will produce electricity for 25 years, and a Solar Panel can be paid off in 5 years time, then simple math can help know the truth. 25 - 5 = 20 You pay for 5 years and after 5 years the solar panels are paid off, and then you have 20 years left. If a Solar Panel was made with "Planned Obsolescence" then it would wear out sooner so that people buy new ones sooner. How about more math? Suppose you pay $10,000 for Solar Panels. 5 years later you pay off that expense. Suppose you then buy $10,000 more for Solar Panels. 10 years go by and you pay off $20,000 total, and so you now produce 20,000 worth of electricity instead of 10,000 dollars worth of electricity. Got that? Is this too complicated for all the economists? After 10 years you buy $20,000 dollars worth of Solar panels to add to $20,000 dollars worth of Solar Panels and 5 more years go by for a total of 15 years, and you still have 10 years left in the first $10,000 dollars worth of Solar Panels. First 5 years $10,000 worth of Solar Panels paid off 10 years (2 x 5 years) $20,000 worth of Solar Panels paid off 15 years (3 x 5 years) $40,000 worth of Solar Panels paid off 20 years (4 x 5 years) $80,000 worth of Solar Panels paid off 25 years (5 x 5 years) $160,000 worth of Solar Panels paid off At the end of 25 years the first $10,000 worth of Solar Panels are worn out. The home owner runs out of room at home to mount the Solar Panels. The Solar Panels pay for themselves in 5 years. That means that they reproduce in 5 years. Do you know how exponential growth rates work? How about some help? The Rule of 72 Now look at how the Legal Criminals use lies to frighten their victims: Damn Lies Really? A quote: Figures often beguile me, particularly when I have the arranging of them myself; in which case the remark attributed to Disraeli would often apply with justice and force: "There are three kinds of lies: lies, damned lies and statistics."

Moon Helium 3What makes the moon worth mining? It's loaded with valuable metals and potential energy sources. The moon is estimated to contain "20 times more titanium and platinum than anywhere on Earth," says Tibi Pulu of ZME Science. Plus, it has something Earth doesn't: helium 3, a rare isotope that's "nonexistent on our planet, that many feel could be the future of energy on Earth and in space." "The moon has never been explored from an entrepreneurial perspective," says Jain.

Half truths ++++++++++++++++++++++++++++++++++++++++ Sure, solar only generates about 1 percent of the electricity in the US. But that will change in a few years, says Pearce, an associate professor of electrical engineering and materials science at Michigan Technological University. The ultimate in renewable energy is about to go mainstream. It's a matter of economics. A new analysis by Pearce and his colleagues at Queen's University in Kingston, Ontario, shows that solar photovoltaic systems are very close to achieving the tipping point: they can make electricity that's as cheap—sometimes cheaper—as what consumers pay their utilities. Here's why. First, the price of solar panels has plummeted. "Since 2009, the cost has dropped 70 percent," says Pearce. But more than that, the assumptions used in previous studies have not given solar an even break. "Historically, when comparing the economics of solar and conventional energy, people have been very conservative," says Pearce. To figure out the true cost of photovoltaic energy, analysts need to consider several variables, including the cost to install and maintain the system, finance charges, how long it lasts, and how much electricity it generates. Pearce and his colleagues performed an exhaustive review of the previous studies and concluded that the values given those variables were out of whack. For example, most analyses assume that the productivity of solar panels will drop at an annual rate of 1 percent or more, a huge overestimation, according to Pearce. "If you buy a top-of-the-line solar panel, it's much less, between 0.1 and 0.2 percent." In addition, "The price of solar equipment has been dropping, so you'd think that the older papers would have higher cost estimates," Pearce says. "That's not necessarily the case." +++++++++++++++++++++++++++++++++++++ What about this: Guarantee With a SolarLease, you pay as you go, instead of all at once. The combination of your low monthly lease payment and smaller electricity bill is typically less than what you pay the utility company today. So you can start saving money from the very first day. Understand how that works. If a third party can profit at your expense, you can keep the profit and cut out the middle man. Why? Because it is less expensive to produce electricity, right now, with Solar Panels, than it is to buy electricity from the non-competitive, monopoly power, "utility" companies.
