Valcent's Releases Profitable Initial Production Estimates For its Vertical Vegetable Growing Systems

Submitted by Bill St. Clair on Sun, 2008-06-29 17:36.

Valcent press release - a new method of growing vegetables promises to make food productiion and biofuels much more efficient. If their numbers are correct, it looks to me like this could solve the world's food and energy problems for a good long time. See photo galleries for their High Density Vertical Growth System and High Density Vertical Bioreactor.

Quote:
El Paso, TX; March 13 - Valcent Products Inc. (OTCBB: VCTPF) -- Data from its fully operational field test plant has confirmed commercial production potential with several companies expressing interest to build out commercial plants on a joint venture basis. A commercial module of one-eighth acre (5,445 square feet) is estimated to have capital costs of $565,000; using a wholesale price for leafy lettuce of $1.10 per head, may have gross annual revenues in excess of $1,300,000 with earnings before tax of approximately $505,000 supporting management's estimated 89% internal rate of return over 10 years.

Valcent's High Density Vertical Vegetable Growing System (VGS) has now been operating over the last six months and has produced leafy lettuce, micro greens, spinach, herbs, mints, beets, strawberries, wheat grass, alfalfa and other grains. During this period, the system has proven production capabilities on average, of approximately 20 times the amount of vegetables per acre grown in a field while requiring only 5% of the water used for field crops. The VGS system will be sold in one-eighth acre modules that contain 1,320 grow panels and the production modules may be scaled, depending on the growers' output and crop diversity requirements.

...

The research and development team of Valcent Products Inc. has now completed twelve months of the algae vertical bioreactor development program. During a 90-day continual production test, algae was being harvested at an average of one gram (dry weight) per liter. This equates to algae bio mass production of 276 tons of algae per acre per year. Achieving the same biomass production rate with an algal species having 50% lipids (oil) content would therefore deliver approximately 33,000 gallons of algae oil per acre per year.

The primary focus of the 90-day continuous production test was determining the robustness of the field test bed. Other secondary tests were also conducted including using different ph levels, C02 levels, fluid temperatures, nutrients, types of algae, and planned system failures. It is important to note that the system has not been optimized for production yields or the best selection of algae species.

Focusing on Solar's Cost

Submitted by Bill St. Clair on Thu, 2008-05-08 06:00.

Tyler Hamilton at Technology Review - a Hollywood-based startup, Sunrgi Solar Energy Systems, has created a concentrated photovoltaic module that they expect to be able to produce electricity at a price competitive with fossil-fuel generation. Hope it works. [gsc]

Quote:
Sunrgi, which emerged out of stealth mode last week, has created a concentrated photovoltaic system that uses a lens to focus sunlight up to 2,000 times onto tiny solar cells that can convert 37.5 percent of the sun's energy into electricity. Stronger concentrations of sunlight allow engineers to use much smaller solar cells, making it more economical to use higher-efficiency--but higher-cost--cells. Sunrgi, for example, will use cells based on gallium arsenside and germanium substrates.

...

Sunrgi estimates that its system will be capable of producing electricity at a wholesale cost of five cents per kilowatt-hour. Prototypes have been built and tested both in the laboratory and in the field, and the company expects to start commercial production in 12 to 15 months...

GeoBulb (TM)

C. Crane is selling an 800 lumen LED light bulb, that uses 8 watts of power and lasts for 30,000 hours. $120. Out of stock until mid-May. 800 lumens is equivalent to a 55 watt light bulb. That's 100 lumens per watt, and 250 hours per dollar. Still quite a bit more expensive than compact fluorescents, which get 1600 lumens (95 watt incandescent) from 23 watts (70 lumens per watt) and glow for 12,000 hours for $4.75 (2526 hours per dollar). I predict that the end of the compact fluorescent is nigh. Long live the LED!

Cancer Therapy Without Side Effects Nearing Trials

Submitted by Bill St. Clair on Mon, 2008-04-14 06:44.

Jennifer Laloup at Wired - John Kanzius has invented a Radiofrequency Cancer Treatment that may soon allow many cancers to be completely eradicated with few or no side affects. Gold nano-particles are attached to targeting molecules, which attach to the cancer cells. Then radio waves are passed through the body, which causes the nano-particles to heat up and fry the attached cancer cells. Human trials may be only three years away. The story was on 60 Minutes last night.

Experts Now Recommend Hands-Only CPR

Submitted by Bill St. Clair on Tue, 2008-04-01 04:13.

Stephanie Nano at Wired - if an adult collapses and stops breathing, The American Heart Association now recommends skipping the mouth-to-mouth breathing and focusing entirely on pressing the center of the chest, 100 times a minute. For children, however, it's usually a breathing problem, not a heart attack, so mouth-to-mouth is still recommended.

Unless she's hot. ;)

Coronary Calcification Predicts Future Heart Attacks and Coronary Death

Submitted by Bill St. Clair on Fri, 2008-03-28 08:28.

Bill Sardi at LewRockwell.com - a report in the New England Journal of Medicine has concluded what I've thought for a long time: cholesterol scores are not a good predictor of heart attack risk. Nope. It's calcification in the major arteries that serve the heart, something that happens more in countries that ingest lots of milk and milk products. Remember, cows' milk is for baby cows. [lew]

Medicine's Cutting Edge: Re-Growing Organs

Submitted by Bill St. Clair on Thu, 2008-03-27 03:18.

Wyatt Andrews at CBS News - thanks to a powder his brother gave him, Lee Spievack grew back the tip of a finger he sliced off in the propeller of a hobby shop airplane. Soon, this technology may provide brand new internal organs, grown from your own cells. [gizmodo]

Quote:
That powder is a substance made from pig bladders called extracellular matrix. It is a mix of protein and connective tissue surgeons often use to repair tendons and it holds some of the secrets behind the emerging new science of regenerative medicine.

...

If this helped Spievack's finger regrow, Badylak says, at least in theory, you should be able to grow a whole limb.

HeartStart Home Defibrillator

Submitted by Bill St. Clair on Sat, 2008-03-15 04:03.

Philips is shipping technology that could save your life.

One of my high school buddies had a heart attack last Sunday. Fortunately, he was at a friend's house. While his friend was getting him on the floor to start CPR, his friend's wife was dialing 911. A cop and two firemen showed up, who were fortunately nearby at the time, and their portable defibrillator saved his life; the CPR didn't start him up. The doctors couldn't find any blocked arteries or any other reason for it, so they diagnosed it as Sudden Cardiac Death, aka Cardiac Arrest. He's had an automatic defibrillator implanted, and expects to be released from the hospital today. Whew!

Had the cop and firemen not been nearby, or had they not had a portable defibrillator, I would likely have lost a friend. That's where Philips' machine comes in. It's automatic, hence very easy to use. $1,299, payable in 1, 5, or 10 interest-free monthly installments, or 12, 18, or 24 months with 18% interest. Prescription required.

First Commercial Fuel Cell Car Hits the Market Next Summer

Submitted by Bill St. Clair on Tue, 2007-11-20 06:49.

The Honda FCX Clarity, a hydrogen-powered fuel cell electric car, will be leased in three California towns in the summer of 2008. They're limiting availability due to a limited supply of hydrogen refueling stations. Their current long-term plans are Plug Power natural-gas-to-hydrogen fueling stations in the home. Initial price: $600/month for three years. Toyota, General Motors, Ford, and likely others are also working on fuel cell cars, but it appears that Honda will be the first to market. Yay!

In praise of Carbon

Submitted by Bill St. Clair on Sun, 2007-10-28 06:57.

John Brignell at Number Watch - some facts about the element of life, Carbon, and the "benign gas" that we breathe out and that plants recycle, using solar energy, into oxygen and food: carbon dioxide. Algore's religious crusade has turned these wonders into demons, for one and only one purpose, to enslave the masses and steal their money. [root]

Quote:
There is no scientific theory linking carbon dioxide to the “runaway” global warming that is the basis of the calamitous predictions. The contribution of the gas to the making of a comfortable planet by the greenhouse effect is well understood, modest and self-limiting. It is only turned into a terror by computer models. These are worthless; depending as they do on extensive guesswork about the ill-understood mechanisms and interactions involved in climate, and involving so many tunable parameters and feedback factors that they could produce any desired result by appropriate tweaking. A quarter of a century ago, before science came under firm bureaucratic control, such models would have been laughed out of court.

The putative experimental evidence is equally dubious. It all sounds very impressive and scary, but on close examination tends to dissolve like the morning mist in the light of the sun. It is only recently that a small troupe of volunteers with few resources has begun a serious audit of the claims. The much vaunted “high-quality” sensor network turns out to be ramshackle almost beyond belief; the processing of the data involves inapplicable methods, glaring errors and unexplained adjustments, which all mysteriously turn out to exaggerate the desired effect. There is a morbid and obsessive secrecy among the practitioners that is quite contrary to the open nature of the scientific method, which prompts the question “What have they got to hide?” Details of publicly funded “research” are kept, quite illegally, from the public who fund it; and only the claimed results, inevitably apocalyptic, are exposed. Such data that have been wrested with great difficulty from their creators almost invariably turn out to be subject to serious dubiety.

Carbon has been framed for purely political purposes.
