Geothermal, Geothermal, Geothermal...I can't say it enough.
Green Energy is like a 4 legged table. Solar, Wind, Geothermal and Hydrogen fuel energies support the table top.
The 3rd leg of the green energy table is Geothermal Energy and is greatly ignored by the general public. Windmills and Solar farms are very visible, easy to understand and extremely popular. Geothermal on the other hand is literally underground and out of sight.
"Out of Sight, Out of Mind" has been the rule.
Geothermal is the only practical commercial energy system that is as efficient and can rival the fossil fuel energy production systems. Geothermal uses the similar drilling technology as the oil industry, only in our case, if a spill occurs it is hot water, not oil.
Bill Gates just announced on ABC News' This Week, that he was getting in to the renewable energy industry. He would like to enter the revolution (evolution) with a lot of funding, billions. He wants to promote the industry to be the world innovation leader, as he did with computers and software. Steve Jobs (Apple) has been on this page for some time. They believe, as many do, that this is the only real solution to our financial crisis and energy needs.
On that same program Robert Reich (Economy Professor UC Berkley and former Secretary of Labor) emphasized that California is the leader in Green Innovation. "Everything Good and Bad starts in California", "California is the future". (Robert Reich).
A positive Public Relations and "Technology Sharing" campaigns are the areas that are severely lacking.
The lack of public awareness of Geothermal potential is disgraceful. Geothermal is the only practical commercial energy system that is as efficient and can rival the fossil fuel energy production systems. Geothermal uses the similar drilling technology as the oil industry, only in our case if a spill occurs it is hot water, not oil.

American Farm Windmill to Wind Turbine Conversion
How to Convert a Windmill Into a Wind Generator
Contributor

Preface by GRNNRG.ORG
One of the problems with residential Wind Turbine is their appearance. A big 2 or 3 blade wind turbine is asthetically unpleasing for the user and his or her neighbors. An American Farm Windmill (12-18 blade) seems to be much more acceptical and can be built relatively cheep, fast and good, meeting the needs of electric power and pleasingly asthetic design. GRNNRG.ORG was created and founded to address such concerns and other concerns like it. One by one we will attempt to eliminate objections to green energy conversion. One more down and more to come.
D.H.
Typical farm windmill
A typical windmill can be converted to generate enough electricity to power a modest sized home. Using the windmill to recharge a battery bank suited to the needs of the home is the simplest and most effective method of wind power storage. The average backyard engineer can convert a windmill to generate electricity in about four hours.
Step 1
Convert the drive shaft of the windmill to turn a generator. Most old windmills were constructed to pump water from the ground, either for livestock or people. As utility companies began to supply water to any homestead inexpensively, such windmills fell out of use. Their main drive shaft turns a pump at the base, which is connected to the water supply in the ground. As the wind turns the vanes, the water is pumped into a reservoir. This shaft must be disconnected where it meets the pump, and windmills can vary in this respect. Some will have the force put to the pump at a 90-degree angle, and some will drive the pump directly without power differential. When the shaft is disconnected, it will be at an angle or straight. The main conversion of this shaft is to weld a large sprocket close to the end of the shaft so that it can turn a bike chain. The shaft measures about 2 inches wide, and can be fitted with the sprocket by sliding it over the end once it is disconnected from the pump. Weld the sprocket so that it can handle the amount of force required to turn the generator.
Step 2
Mount the generator with the main pulley fitted with a smaller sprocket than the windmill's drive shaft. Typically, alternators and generators will have a pulley at the end, to be driven by a belt. Weld the bicycle sprocket to the end of the pulley to allow the unit to be driven by the chain. Place the generator/alternator at the base of the windmill, and align it so that the pulley sprocket can be linked to the chain attached to the windmill shaft. Usually the frame of the windmill will work for this mount, but in some cases it is necessary to raise the generator up on cement blocks or another heavy-duty structure.
Step 3
Assemble the battery bank and wire it to the generator. Analyze the power requirements of the home to determine how many 12-volt deep cycle batteries are required to power the home at its peak usage. (20 batteries wired in two series of 10 will provide 24 volts of power with several amp-hours of draw.)
Step 4
Install the inverter and wire it to the home. Wire the inverter to the leads on the battery bank. The bank--which will have one negative and one positive terminal--will run through the inverter, which "steps" the power up to 110 volt, suitable for use in the home. Inverters come in different wattages and different levels of quality; the wattage should match the power requirements of the house. Run the standard 110-volt power lines from the inverter to the home's fuse panel with the outdoor cable.
Step 5
Test all connections with a voltmeter to ensure a circuit path, then release the brake mechanism on the windmill to activate the power generation.
Tips & Warnings
Get a high quality, "true sine wave" inverter for use with delicate electronics such as computers.
Do not work on "live" electrical equipment. Always disconnect the power first.

Initial NIF experiments meet requirements
for fusion ignition
New physics effect achieves symmetrical target compression
LIVERMORE, Calif. — The first experiments at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) have demonstrated a unique physics effect that bodes well for NIF’s success in generating a self-sustaining nuclear fusion reaction.
In inertial confinement fusion (ICF) experiments on NIF, the energy of 192 powerful laser beams is fired into a pencil-eraser-sized cylinder called a hohlraum, which contains a tiny spherical target filled with deuterium and tritium, two isotopes of hydrogen. Rocket-like compression of the fuel capsule forces the hydrogen nuclei to combine, or fuse, releasing many times more energy than the laser energy that was required to spark the reaction. Fusion energy is what powers the sun and stars.
The interplay between NIF’s high-energy laser beams and the hot plasma in NIF fusion targets, known as laser-plasma interactions, or LPI, has long been regarded as a major challenge in ICF research because of the tendency to scatter the laser beams and dissipate their energy. But during a series of test shots using helium- and hydrogen-filled targets last fall, NIF researchers were able to use LPI effects to their advantage to adjust the energy distribution of NIF’s laser beams.
The experiments, described in an article in today’s edition of Science Express, the online version of the journal Science, resulted in highly symmetrical compression of simulated fuel capsules – a requirement for NIF to achieve its goal of fusion ignition and energy gain when ignition experiments begin later this year.
“Laser-plasma interactions are an instability, and in many cases they can surprise you,” said ICF Program Director Brian MacGowan. “However, we showed in the experiments that we could use laser-plasma interactions to transfer energy and actually control symmetry in the hohlraum. Overall, we didn’t find any pathological problem with laser-plasma interactions that would prevent us generating a hohlraum suitable for ignition.”
Using LPI effects to tune ICF laser energy is “a very elegant way to do it,” said Siegfried Glenzer, NIF plasma physics group leader. “You can change the laser wavelengths and get the power where it’s needed without increasing the power of individual beams. This way you can make maximum use of all the available laser beam energy.”
In the Science Express article, Glenzer, MacGowan and their NIF colleagues reported that “self-generated plasma-optics gratings on either end of the hohlraum tune the laser power distribution in the hohlraum, producing symmetric X-ray drive.” Glenzer said the gratings act like tiny prisms, redirecting the energy of some of the laser beams just as a prism splits and redirects sunlight according to its wavelength.
Glenzer attributed the new LPI phenomenon to the size of the test hohlraums, which, while somewhat smaller than actual NIF ignition targets, are two to three times larger than hohlraums used in previous ICF experiments at other laser facilities. He said the increased amount of the high-temperature, low-density plasma in the areas where the laser beams enter the hohlraum was responsible for the spontaneous generation of the plasma gratings.
The technique of slightly shifting the wavelength of some laser beams to control the transfer of energy between the beams and equalize the laser power distribution in the hohlraum had been predicted and modeled by NIF scientists using high-fidelity three-dimensional simulations. In last fall’s experiments, an initially asymmetric target implosion with a “pancake” shape was changed to a spherical shape by the wavelength-shifting technique, validating the modeling results.
The NIF laser system began firing all 192 laser beams onto targets in June 2009. In order to characterize the X-ray drive achieved inside the target cylinders as the laser energy is ramped up, these first experiments were conducted at lower laser energies and on smaller targets than will be used for ignition experiments. These targets used cryogenically cooled gas-filled capsules that act as substitutes for the fusion fuel capsules that will be used in the ignition campaign that begins this summer.
Before the wavelength-shifting effects were tested, the only way to adjust the laser energy reaching the walls of the hohlraum, where it is converted into X-rays that heat and ablate the outer surface of the fuel capsule and cause the compression of the fuel inside the capsule, was to adjust the relative energy of the laser beams in the early stages of a shot, during preamplification.
By taking advantage of the LPI effects in the target, as the beams crossed at the entrance of the hohlraums, the scientists could make use of minute wavelength adjustments, ranging from a fraction of an angstrom to a few angstroms (an angstrom is one ten-billionth of a meter, about the size of an atom). With the LPI scheme, “you can run every beam at maximum power and have another distribution mechanism to achieve symmetry,” Glenzer said.
The test shots proved NIF’s ability to deliver sufficient energy to the hohlraum to reach the radiation temperatures – more than 3 million degrees Centigrade – needed to create the intense bath of X-rays that compress the fuel capsule. When NIF scientists extrapolate the results of the initial experiments to higher-energy shots on full-sized hohlraums, “we feel we will be able to create the necessary hohlraum conditions to drive an implosion to ignition,” said Jeff Atherton, director of NIF experiments.
At the end of the experimental campaign, the NIF lasers set a world record by firing more than one megajoule of ultraviolet energy into a hohlraum – more than 30 times the energy previously delivered to a target by any laser system.
“This accomplishment is a major milestone that demonstrates both the power and the reliability of NIF’s integrated laser system, the precision targets and the integration of the scientific diagnostics needed to begin ignition experiments,” said NIF Director Ed Moses. “NIF has shown that it can consistently deliver the energy required to conduct ignition experiments later this year.”
NIF’s next step is to move to ignition-like fuel capsules that require the fuel to be in a frozen hydrogen layer (at 425 degrees Fahrenheit below zero) inside the fuel capsule. NIF is currently being made ready to begin experiments with ignition-like fuel capsules in the summer of 2010.
NIF (lasers.llnl.gov), the world’s largest laser facility, is the first facility expected to achieve fusion ignition and energy gain in a laboratory setting. NIF is an essential part of the National Nuclear Security Administration’s Stockpile Stewardship Program, which ensures the reliability and safety of the nation’s nuclear weapons stockpile without live testing. NIF experiments will also be used to conduct astrophysics and basic science research and to develop carbon-free, limitless fusion energy.
The NIF fusion ignition experiments are part of the National Ignition Campaign (NIC). NIC is a partnership among the National Nuclear Security Administration (NNSA), Lawrence Livermore National Laboratory, Los Alamos National Laboratory, the Laboratory for Laser Energetics, General Atomics, and Sandia National Laboratories as well as many other national laboratories and universities.
Founded in 1952, Lawrence Livermore National Laboratory is a national security laboratory that develops science and engineering technology and provides innovative solutions to our nation's most important challenges. Lawrence Livermore National Laboratory is managed by Lawrence Livermore National Security, LLC for the U.S. Department of Energy's National Nuclear Security Administration.

Electric Power Producing Artificial Trees
Another objection to wind, solar and geothermal devices have been resolved. That objection has been the un-natural aesthetics of 'Solar panels", "Wind turbines" and "thermalvoltic pumps"
An artificial tree that produces electricy from solar, wind, and geothermal energy seems to be the obilous solution.
A London based company called Solar Botanic intends to use Energy Harvesting Trees to generate solar as well as wind energy utilizing an emerging science called “biomimicry.”
Biomimicry mimics nature’s processes in order to produce clean, environmental friendly energy.
Solar Botanic claims that its energy capturing powerhouse is going to be Nanoleaf.
On their website, they say, “A Nanoleaf is thin like a natural leaf, when outside forces, like the wind pushes the Nanoleaf back and forth, mechanical stresses appear in the petiole, twig and branches. When thousands of Nanoleaves flap back and forth due to wind, millions and millions of Pico watts are generated, the stronger the wind, the more energy is generated.”
Nanoleaves
Sun, wind, water, earth and life touch our living senses immediately always, everywhere and without any intervention of reason. They simply are there in their unmatched variety, moving us, our moods, memories, imaginations, intensions and plans.
To capitalize on the wealth of designs and processes found in nature, engineering and technology gave us the ingredients, creative thinking, and unique solutions made it possible to bring all this together into a natural looking leaf - the Nanoleaf.
To complete the tree for multi energy exploitation, the petiole twigs and branches are incorporated with Nano piezo-electric elements. A Nanoleaf is thin like a natural leaf, when outside forces, like the wind pushes the Nanoleaf back and forth, mechanical stresses appear in the petiole, twig and branches. When thousands of Nanoleaves flap back and forth due to wind, millions and millions of Pico watts are generated, the stronger the wind, the more energy is generated.
Our Nanoleaves only reflect a small part of the sunlight that strikes them, mostly the green light, and the rest of the spectrum is efficiently converted into electricity.
Besides converting the visible spectrum of light, our Nanoleaves also convert the invisible light, known as infrared light or radiation, we can’t see it, but we can feel it - it’s warm - that’s why we call it radiation. Due to the unique combination of photovoltaic and thermovoltaic in our Nanoleaves it converts this thermal radiation into electricity, even hours after the sun has set.
The more wind there is,the more Nanoleaves are moved. Wind that is moving thousands of Nanoleaves in a tree canopy are causing mechanical strain in the petiole, twigs and branches. Nano piezo-electric elements incorporated in the petiole twigs and branches are the tiny Nano piezo-electric elements that will generate millions and millions of Pico watts as these thousands of Nanoleaves flap back and forth due to wind. The stronger the wind, the higher the “flap” frequency, and therefore the larger the watts generated in the petiole, twigs and branches.
With the progress in nano technology, the photovoltaic, thermovoltaic and piezo electric materials are becoming more efficient and combined in one system it will give these products more efficiency and we believe that soon, SolarBotanic will be a mainstream green energy provider, more reliable/cheaper and above all better looking.

An artificial tree that produces electricy from solar, wind, and geothermal energy seems to be the obilous solution.
A London based company called Solar Botanic intends to use Energy Harvesting Trees to generate solar as well as wind energy utilizing an emerging science called “biomimicry.”
Biomimicry mimics nature’s processes in order to produce clean, environmental friendly energy.
Solar Botanic claims that its energy capturing powerhouse is going to be Nanoleaf.
On their website, they say, “A Nanoleaf is thin like a natural leaf, when outside forces, like the wind pushes the Nanoleaf back and forth, mechanical stresses appear in the petiole, twig and branches. When thousands of Nanoleaves flap back and forth due to wind, millions and millions of Pico watts are generated, the stronger the wind, the more energy is generated.”
Nanoleaves
Sun, wind, water, earth and life touch our living senses immediately always, everywhere and without any intervention of reason. They simply are there in their unmatched variety, moving us, our moods, memories, imaginations, intensions and plans.
To capitalize on the wealth of designs and processes found in nature, engineering and technology gave us the ingredients, creative thinking, and unique solutions made it possible to bring all this together into a natural looking leaf - the Nanoleaf.
To complete the tree for multi energy exploitation, the petiole twigs and branches are incorporated with Nano piezo-electric elements. A Nanoleaf is thin like a natural leaf, when outside forces, like the wind pushes the Nanoleaf back and forth, mechanical stresses appear in the petiole, twig and branches. When thousands of Nanoleaves flap back and forth due to wind, millions and millions of Pico watts are generated, the stronger the wind, the more energy is generated.
Our Nanoleaves only reflect a small part of the sunlight that strikes them, mostly the green light, and the rest of the spectrum is efficiently converted into electricity.
Besides converting the visible spectrum of light, our Nanoleaves also convert the invisible light, known as infrared light or radiation, we can’t see it, but we can feel it - it’s warm - that’s why we call it radiation. Due to the unique combination of photovoltaic and thermovoltaic in our Nanoleaves it converts this thermal radiation into electricity, even hours after the sun has set.
The more wind there is,the more Nanoleaves are moved. Wind that is moving thousands of Nanoleaves in a tree canopy are causing mechanical strain in the petiole, twigs and branches. Nano piezo-electric elements incorporated in the petiole twigs and branches are the tiny Nano piezo-electric elements that will generate millions and millions of Pico watts as these thousands of Nanoleaves flap back and forth due to wind. The stronger the wind, the higher the “flap” frequency, and therefore the larger the watts generated in the petiole, twigs and branches.

Electric Vehicles, Solar and Wind Energy Home retrofitting
Electric Vehicles
Documentary Filmmaker, Chris Paine has produced a wonderful documentary, 'Who Killed the Electric Car?'
The film's premise is that the EV (electric vehicle) produced by General Motors was so desirable that GM stopped production, dismantled the production lines and destroyed the existing EVs to try and discourage the public's desire for this kind of automobile.
Some of the adversaries of the EVs, claim that even though the cars themselves are environmentally clean, the electricity used to 'charge' the cars require electricity that is produced by Coal Burning Power Plants. This is a half truth. 55% of the Power Plants we have now are Coal Burning, 45% are not. This is the only legitimate claim adversaries to EV have that seems to claim that indirectly the EV is still a polluting vehicle.
We at GRNNRG.ORG believe that with the residential green energy retrofitting of individuals home with wind, solar and in some cases geothermal energy production, would eliminate indirect pollution. An individual could produce enough 'Home Produced Energy' to supply a household and it's occupant's electric cars with more than enough electricity.
We particularly like what is being done in converting 'classic' automobiles to electric.
Lincvolt in the Northern California Bay Area (www.lincvolt.com) have successfully restored a 1959 Lincoln Continental with an electric motor and batteries and are taking on a cross country road tour to take this cool concept directly to the public. This is the inspiration of singer/songwriter Neil Young.
In Los Angeles, EMC is doing the same thing. They have a TV program on the 'Planet Green' channel, 'Gadgets Electric Garage" where a 1967 Camaro is restored with an electric motor and batteries.
We need more of the same. '60s VW Beetles, 65 Mustangs, muscle cars, large luxury cars can all come back, free of polluting and carbon footprints.
Wouldn't it be nice if we could live out the rest if our lives with out a electric or gasoline bill. This is not just possible and plausible, but is probable as well. The current technology exists and has existed for nearly 20 years.
This technology should be in all new housing and existing housing should be retro fitted. The public can be reluctant to convert to green energy production if it is at all inconvenient or has a cost that is any more than their monthly electric bill.
The green system would need to provide enough electricity to power a home and the automobiles of it's occupants.
Retrofitting existing Homes
The cost of install the green system in a home should be equal to the homes existing monthly electric bill over a period of 5 years. At the end of this period there should be no cost for the green produced electricity for the life of the home.
If your average monthly electric bill is $100 per month, the system total installation cost should be $6000. Small 1,200 ft home.
If your average monthly electric bill is $500 per month, the system total installation cost should be $30,000. Large 5,000
We recommend a system of solar and wind, where it is practical, depending on the geographic atmospheric conditions. Geo-thermal steam in areas that lack sufficient wind or sunlight.
On my home conversion project (wind and solar retrofitting), I called 5 contractors for estimates. They all came to about the same cost estimates.
About $20,000 for a Wind Turbine (About $14,500 after CA State rebate and about $8,500 with the Fed Tax Credit)
24 (190 W) solar panels cost (4.4 A/C, 5.25 D/C system) about $35,000 ($25,500 after CA State rebate and 18,000 after the Fed Tax Credit).
From a green energy contractor, a combo system would cost about, $20,000-$25,000 (after rebates and tax credits) for a small 1200 ft home. Unfortunately the financing cost is $40,000-$50,000. The rebates and tax credit come later.
I am now looking into multiple (3 or 4) smaller and more environmentally aesthetic windmill turbines. I live in the high desert with intermittent periods of high wind speeds and lots of sunlight. With each wind turbine having different wind speed efficiencies and a dozen or so roof top solar panels, I should be set
My goal is to get this system for a total cost of under $10,000 before rebates and Tax Credits. I found several smaller wind turbine kits in the $600-$1,000 range on the Internet. I'll let you know what I find.

Blog#1 Welcome and Windmills
Salutations and Welcome,
We have finally arrived.
We are here to try and make sense of the Green Energy world. We will collect the latest research on renewable energy innovations and bring it to you in layman's terms.
We will encourage unconventional experimentation and 'outside of the box' concepts.
We will also focus on green solutions that touch our everyday lives, from composting kitchen waste to commuting. We will also tackle controversy in the green energy industry.
Small Wind Turbines.
Our first subject of opinion is the efficiency of multi blade (12-18) American Windmill design, normally used to pump water. Very little is mentioned in the conventional literature on wind power except 'don't do it'
Than I ran across a NASA labeled report (the full report on our 'conservation page').
I can not endorse it's legitimacy, but it indicates that a multi blade system would be more efficient under lower wind speeds (8-18 mph) than a 2 or 3 blade system.
I have yet to see any testing conclusions to verify the result one way or another.
In some communities the aesthetics on a modern 30' high or higher) wind turbine and the aesthetics of an American Farm Windmill design is more desirable in rural and equestrian communities, where green energy is wanted and very practical.
I am personally retrofitting my modest home with a solar and wind system. I will be seeking the most efficient and frugal system I can find or put together and Blog my progress for your personal information and entertainment. All my successes and failures will be published here. Keep in mind, sometimes more can be learned from failing than succeeding.
Why retro fit NOW? With the federal tax credit and California's incentive rebate, I can't afford not to. My goal is to keep the cost of my system under my current electric bill and have it paid off in 5 years.
Contact Us.
We are interested in what you have to say. If you have information on the multi blade fan controversy or other green energy subjects, please e-mail us at d.hrshbrgr@gmail.com
We are a registered Non-Profit organization and rely on your donations and contributions.
If you are in the renewable energy business and want to provide green energy for others, we can help others become aware of your products and services.
We aren't professional experts, but we know a lot of people who are.
We can provide common sense answers to fundamental questions.
Most Sincerely,
D.H.
