The first solar dehydrator is shown by robert and marina at dell artimus farm. The solar heat comes from a heated panel at the bottom, and there is a black chimney at the top that creates a draw. They use a stainless steel screen. The dryer is a year and a half old. They have dried beans, flowers, cherries, grapes (raisins), kale, walnuts and apples. They tried some tomatoes, but those ended up as pig food.

Matt at feral farm shows a “down draft solar dehydrator.” The solar heat enters at the top and then goes down. Because as it gathers moisture, the solar heated air gets heavier. He has nettles in there.

Mark Vander Meer, of wildland conservation service in Missoula, Montana shows off his solar food dehydrator still loaded with dried plums. Those plums have been in there all fall, winter and most of the spring. He talks about trying to dry fruit with electric food dehydrators and how expensive that was. This solar dehydrator also uses the down draft technique. He says plums take three days and apples take a day and a half.

These are all passive systems. There are no fans.

Obama ‘Energy Security Trust’ Pushes Green Research And Natural Gas Development

President Barack Obama toured the Argonne National Laboratory outside Chicago on Friday and announced his plans for an “Energy Security Trust” to further clean energy research and development in the U.S.

The trust, which will be funded by federal royalties from offshore oil and gas drilling and not add to the budget deficit, will provide for $2 billion in research over the next 10 years. According to the White House, it will advance research into technologies like electric vehicle batteries, biofuels and hydrogen fuel cells.

Obama said on Friday at Argonne, “We have to keep investing in scientific research,” and lamented the impact of the federal budget sequester on U.S. research. “We cant afford to miss these opportunities while the rest of the world races forward,” the president argued.

Obama’s plan also funds natural gas research, furthering the president’s forthright support of an “all of the above” energy strategy and “responsibly tapping” U.S. natural gas reserves.

The president’s “Blueprint for a Clean and Secure Energy Future” advocates for “accelerating the growth” of natural gas in the transportation sector. Although increased utilization of natural gas is partially responsible for a decline in U.S. carbon dioxide emissions, significant leakage of methane — a shorter-lived but more potent greenhouse gas than CO2 — may negate environmental benefits over coal.

Obama’s “blueprint” also gives a nod to the coal industry with “significant funding for clean coal technology.” Carbon sequestration from coal-fired power plants has been called “mythical” by environmentalists, who have criticized Obama’s Energy secretary nominee, Ernest Moniz, for supporting the concept.

The president originally proposed the Energy Security Trust in his 2013 State of the Union address. “If a nonpartisan coalition of CEOs and retired generals and admirals can get behind this idea, then so can we,” he declared. “Let’s take their advice and free our families and businesses from the painful spikes in gas prices we’ve put up with for far too long.”

FoodAbundance

Published on Mar 20, 2012

Over 6,000 pounds of food per year, on 1/10 acre located just 15 minutes from downtown Los Angeles. The Dervaes family grows over 400 species of plants, 4,300 pounds of vegetable food, 900 chicken and 1,000 duck eggs, 25 lbs of honey, plus seasonal fruits throughout the year.

From 1/10th of an acre, four people manage to get over 90% of their daily food and the family reports earnings of $20,000 per year (AFTER they eat from what is produced). This is done without the use of the expensive & destructive synthetic chemicals associated with industrial mono-cropping, while simultaneously improving the fertility and overall condition of the land being used to grow this food on. Scaled up to an acre, that would equal $200,000 per year!

To follow the Dervaes and their Urban Homesteading activites, you can find them at http://urbanhomestead.org

Urban and near-urban farming can be highly productive, causing whatever size of land you have to work with to produce with more abundance. It is time to solve hunger worldwide, through creating local food abundance…. Anyone can do it, once you learn how.

Early on in my survival preparations, I bought lots of whole wheat flour and yeast packets for making bread. Flour is a lot cheaper than MRE’s and it takes up less space. Then one day my wife said, “If a disaster happens and the power is out, how are you going to bake bread?” Great question! And I felt pretty stupid because I didn’t have an answer. After a little research, I learned that as long as you can get a fire going, there are many things you can do with your bread ingredients.

Fry It: Donuts are just fried bread and sugar. Simply mix the dough as instructed and let it rise. Instead of forming a loaf, split it into two large pieces and pat them down until they’re about a 1/2 inch thick. Now let them rise again until them rise until they’re a full inch thick. Meanwhile, heat a pan of oil over your fire and when the bread is read, slip one of the pieces into the pan. When the bottom is brown, flip it over and fry the other side. Repeat with the other piece. When your bread is ready, drain off the excess oil, tear off a piece and enjoy. A little butter and honey or syrup and some powdered sugar will make them a delicious treat that is good anytime, whether you’re in a disaster scenario or not.

Technology Harvests Energy from Railroad Train Vibrations

 

ScienceDaily

 

Stony Brook University engineers have won a national award for an innovative energy harvester that has the potential to save millions of dollars in energy costs for railroads while reducing carbon dioxide emissions.

The team’s work, “Mechanical Motion Rectifier (MMR) based Railroad Energy Harvester,” was awarded “Best Application of Energy Harvesting” at the Energy Harvesting and Storage USA 2012 conference, held in Washington, DC on November 7-8, 2012.

The Stony Brook team, led by Professor Lei Zuo and two graduate students Teng Lin and John Wang from the Department of Mechanical Engineering and Advanced Energy Research and Technology Center, developed a new type of energy harvester that converts the irregular, oscillatory motion of train-induced rail track vibrations into regular, unidirectional motion, in the same way that an electric voltage rectifier converts AC voltage into DC.

Professor Zuo estimates that the invention could save more than $10 million in trackside power supply costs for railroads in New York State alone, along with a reduction of 3000 tons per year of CO2 and a half million dollars of electricity savings.

“The U.S. has the longest rail tracks in the world, approximately 140,700 miles; that are often in remote areas. It is very important but also very costly to power the track-side electrical infrastructure, such as the signal lights, cross gates, track switches and monitoring sensors,” Professor Zuo said. “Our invention, the ‘Mechanical Motion Rectifier (MMR) based Railroad Energy Harvester,’ can harness 200 watts of electric energy from train-induced track deflections to power the track-side electrical devices. By using two one-way clutches, the innovative mechanical motion rectifier converts the irregular up-and-down vibration motion into unidirectional rotation of the generator, thus breaking the fundamental challenge of vibration energy harvesting and offering significant advantages of high efficiency and high reliability.”

The technology of the MMR based Railroad Energy Harvester has been licensed to Electric Truck, LLC/Harvest NRG, Inc. The project is supported by the U.S. Department of Transportation’s University Transportation Research Center (UTRC-II), New York State Energy Research and Development Authority (NYSERDA), SUNY Research Foundation and private industry.

In addition to the economic, environmental and energy benefits of the device, Professor Zuo said the most important technical innovations in this harvester are the unique mechanical motion rectifier that changes the irregular up-and-down vibration into regular unidirectional rotation of the electrical generator, and synergistically integrating the fly wheel into the energy harvesting system to further increase energy conversion efficiency and stable power output. Another important feature is the creative implementation of MMR in one shaft design, which proves to increase the energy converting efficiency to over 70 percent.

“With the MMR design, the technology advances the traditional energy harvesting, including directly generating high-quality DC power without an electrical rectifier in the vibration environment; enabling an electrical generator to rotate in one direction with relative steady speed in a more efficient speed region; and changing the negative influence of motion inertia into positive, thus reducing the mechanical stress and increasing system reliability,” he said. “Such a design not only avoids the challenges of friction and impact induced by oscillation motion, but also enables us to make full use of the pulse-like features of track vibration to harvest more energy.”

Professor Zuo and his team have been working on vibration and thermoelectric energy harvesting in the past several years to harness power from different sources, including trains, cars, tall buildings and ocean waves. In 2011, the team won a prestigious R&D 100 Award — dubbed the “Oscar of Invention” — for the development of retrofit energy-harvesting shock absorbers that convert vibration, bumps, and motion experienced by the suspension of a vehicle or train into electric power. The regenerative shock absorber for cars can harvest 100-400 watts from the vehicle vibrations under normal driving conditions. The shock absorbers also won the Energy Harvesting and Storage USA 2010 award for Best Technology Development of Energy Harvesting.

New Rule Could Reenergize Clean-Energy In New Jersey

by Staff Writers
Newark NJ (SPX)


File image.

The federal government’s big-picture approach to power transmission could help New Jersey recharge its own aggressive programs to develop solar power and other forms of renewable energy, said Roy M. Palk, Senior Energy Advisor for the national law firm LeClairRyan, during an Oct. 24 presentation to the New Jersey Bar Association’s Public Utilities Law Section.

“For decades, the United States lacked the underpinnings of any national policy aimed at encouraging closer coordination among users of the grid, from independent power producers and transmission owners, to decades-old, government-regulated public utilities,” said the Glen Allen, Va.-based attorney.

“But thanks to a series of FERC regulations-most recently Order 1000, a final version of which was published in May-the country now appears to be taking important steps toward creating a truly national energy-transmission grid along the lines of the Interstate Highway System.”

A 40-year veteran of the U.S. power industry and former president and CEO of East Kentucky Power Cooperative, Palk gave the presentation-”The Impact of Federal Regulatory Commission (FERC) Order 1000″-at LeClairRyan’s office in Newark. While New Jersey is second only to California in the development of solar power, he noted, its renewable-energy program has lost some momentum, in part because the country’s transmission grid continues to be so fragmented and antiquated.

“Over time, Order 1000 could help New Jersey and other states ramp up the amount of renewable energy they can move through the grid and bring to market,” Palk said. “This is important, because our financial and national security infrastructure is more dependent than ever on a reliable, robust and efficient transmission grid.”

During the presentation, Palk provided a contextual overview of FERC Order 1000 and its potential effects. This major policy experiment, he noted, aims to create an even playing field for transmission planning, construction and utilization, such that no single power resource ever holds another hostage.

“The intent is to promote regional and interregional coordination as never before,” Palk said.

“The three primary components of the order deal with transmission-planning, cost-allocation reforms-i.e., who picks up the cost of energy transmission and under what circumstances-and the overall interplay of regulated power generators and movers. FERC Order 1000 also strongly encourages non-jurisdictional entities, whether a startup focused on renewable energy, say, or a municipal electric group, to explain how they aim to fit into the evolving grid.”

Palk provided a short history of the order and its predecessors, and also discussed the current role of the nation’s regional transportation organizations (RTOs), the voluntary formation of which was encouraged by FERC Order 2000. “The goal was to administer the transmission grid on a regional basis throughout North America, including Canada,” Palk noted.

“Some of these RTOs are very large. Valley Forge, Pa.-based PJM, for example, serves all or part of 13 states and the District of Columbia. In other words, utilities across North America have already gained substantial experience in working together to move power across the grid.”

FERC Order 1000 aims to take this collaboration to the next level. It directed public utilities to submit their plans for cost-sharing and regional coordination by Oct. 11, with plans for inter-regional planning and cost-allocation methodologies due April 11, 2013. Some utilities in the South and Midwest now have until Feb. 8 to submit their cost-sharing and regional coordination plans, thanks to a 120-day deadline extension.

Like many in the industry, Palk is cautiously optimistic about the impact of FERC Order 1000. “FERC’s order to create a level playing field among the utilities could help open the transmission market, to be sure, but this can only happen if the components of accessibility are fully complied with and available to all of the utilities and the purchasers of power,” he said.

“The order calls for ‘fair and equitable’ cost-allocation, for example, but the subjectivity here makes this fertile ground for disputes and challenges. The definition of ‘fair,’ after all, depends on whose ox is getting gored.”

Order 1000 has generated no shortage of doubters and skeptics, particularly when it comes to these cost-sharing formulae, Palk noted.

“Will the smaller-scale grid users be forced to pay unfair rates in order to piggyback on the growing grid?” he asked. “Will the big utilities, in the end, be allowed to dictate unfavorable terms and shape the evolution of the nation’s transmission infrastructure in ways that benefit their own bottom lines?”

The U.S. power industry is watching to find out whether the regulations will accomplish their aims, or if they will fizzle and fail.

“In coming months, FERC’s analysts will be looking hard at the submitted filings to see whether they are the product of realism and good faith, or of a more provisional attitude in which companies are, not to put too fine a point on it, mostly ‘looking out for No. 1,’ ” Palk said. “But I am hopeful FERC Order 1000 will be a success. After all, the stakes here could hardly be higher.”

10 Ways to Keep Your Power and Computers Operational When TSHTF,

by Jesse Gendron, survivingsurvivalism.com

One of the biggest questions we get on our website, survivingsurvivalism.com, is how to begin achieving off-grid/energy independent status. Not everyone can afford to go out and buy a 5 kilowatt solar array and the associated batteries. This article is written for those of you who want to begin your road to energy independence, as well as being able to use your laptop, mobil devices, etc..

1. Switch to Linux

Linux is an operating system -the way that Windows is an operating system -usable on PCs, MAC and Android devices. Linux’s biggest advantage, other than being free, is that it does not allow viruses to infect your system. Any change to your system must be verified with your system password, so a virus cannot slip in. Applications such as word processing, video editing, spreadsheet programs and just about anything you can do on a Windows system are all also free. The goal of Linux as a community is to make software available to anyone who can use or develop it.

One if its biggest advantages is the lack of anti-distribution or pirating measures like product keys or need to activate. As Windows operating systems require online activation, if the Internet is for any reason not available making activation impossible, you could potentially be unable to restore your hard drive without the ability to activate in 30 days.

2. Set up local communications with routers.

So, the internet is down and your modem rendered useless. What ever you do, don’t dispose of that wireless router. This can be an indispensable device for keeping local communication possible. This can be done by setting up a VPN (Virtual Private Network).

The installation process of a VPN will depend on which operating system you use. If running Linux, you can easily set up an alternate to a VPN called IPTux. It is less secure than a VPN, but simpler. This simple to setup piece of software works more or less plug and play. Have your router powered up and broadcasting and have all PCs that receive your wi-fi signal run the IPTux application. To use it, just start the program in the system hooked up to your router (does not have to be connected to the Internet) and start chatting. This is a simple and effective way to keep in touch with a small community in a blackout scenario and can go as far as you have repeaters for. If you are concerned about securing your communications, a VPN would be recommended.

3. Keep alternative power systems, even if you’re tied into the grid.

There’s no reason not to use solar or any other type of free energy, even if your needs are more than a simple off-grid power system can handle . You could still have your lower wattage devices running on solar or wind or other power source and not only save on your electric bill, but be prepared to still have basic appliances working if power is unavailable. It is always a good idea to dabble with off the grid technology. The more you put in to it, the more prepared you are to handle potential blackouts.

4. Have at least one man-powered generator for low sun/wind days.

With the many natural forces that you can harness as clean electricity, there will still be days when mother nature needs a break. If you want to keep your power more reliable than the forces of nature, itEs good to have a hand crank, stationary bicycle, treadmill, or anything you could use to manually spin a generator. Something as simple as a battery operated drill gun can be used to generate safe, reliable, clean power. This can be crucial. You may have a dire need of your power and be forced to wait until more favorable weather. You can avoid this by using a power source that runs on calories, the most simple of which is a hand crank. A generator with a crank handle can produce power right away. The stationary bicycle can also be an excellent choice. A treadmill however is unique because it already has a motor connected to it that can be reversed with blocking diodes.

 

5. Save important software and operating systems.

You can download a Linux operating system and keep it on a flashdrive for posterity. Many contemporary Linux users will just download the software each time they restore, but you may eventually want to restore your hard drive or update your Operating System when the internet is not available. In this case, you want to have any software, operating systems, and data files backed up. ItEs as simple as saving packs and folders to a thumb drive.

Solyndra redux? SoloPower about to qualify for federal loan guarantees

SoloPower, a San Jose, Calif.-based solar power company, is set this week to open a $340 million manufacturing facility in Portland, Ore. When it does, it takes a key step toward qualifying for a per-approved $197 million federal loan guarantee.

If this sounds familiar it’s because SoloPower is drawing comparisons to Solyndra, the Fremont, Calif., solar power company that managed to snag $535 million in federal loan guarantees before the whole thing collapsed last year, raising a howl from critics of the Obama administration’s use of federal fund to jump start what are supposed to be promising, job-creating green-tech companies.

According to a report from Reuters, SoloPower uses some of the same technology as Solyndra to make lightweight, flexible solar panels. Given the political hay Obama’s critics made last year from Solyndra’s failure, comparisons were inevitable.

SoloPower will, of course, do its best to fend off comparisons, claiming its products are more versatile, it has a better business plan and it has stricter cost controls than its ill-fated predecessor. That could well be. It’s certainly starting production on a smaller scale than Solyndra. Its plant in Portland will initially employ only about 90 people. Solyndra had about 1,100 on its payroll when it pulled the plug.

But SoloPower is also painfully aware that collecting any federal funding these days comes brings intense scrutiny. The loan guarantee, conditionally approved in 2011, comes from the same Energy Policy Act pool of money that backed Solyndra. At the same time, solar power market conditions remain tough in the face of shrinking government subsidies and stiff competition from China.

All this piles enormous pressure on SoloPower. Meanwhile, opponents of government investment in any industry are watching their every move like buzzards, or hawks, depending on your viewpoint.
