80% Efficient Nano-Solar Panel Macro Stupid


October 30th, 2008

The Idaho National Laboratory claims to have designed a nano-solar panel that has an 80% efficiency, double the efficiency of the best and most expensive solar panels used today.

How does it work? Well... it actually doesn't.

An array of loop nanoantennas is imprinted on plastic and imaged with a scanning electron microscope. The deposited wire is roughly 200 nanometers thick. Because of their size, the nanoantennas absorb energy in the infrared part of the spectrum, just outside the range of what is visible to the eye. The sun radiates a lot of infrared energy, some of which is soaked up by the earth and later released as radiation for hours after sunset. Nanoantennas can take in energy from both sunlight and the earth's heat, with higher efficiency than conventional solar cells.

I think these antennas really have the potential to replace traditional solar panels," says physicist Steven Novack, who spoke about the technology in November at the National Nano Engineering Conference in Boston.

While the Idaho National Laboratory can make the nanoantennas, they haven't figured out yet how to make them actually transmit electricity. Can someone say stupid? That's a little like giving a man starving of thirst a bottle of water and then saying, "Oh, by the way, the bottle is made out of steel and we forgot to put a hole in it."

Another problem I have with this nano-crap is that it is extremely fragile. Imagine someone throwing a rock at a solar panel. It breaks. For a nano-solar panel, a fart would do the same damage. Even in a protective case, imagine the disruption that a single drop of water rolling along the surface would cause to the nanoantennas or a bug running along its surface.

Nano technology works great in a scientific lab done by a man in a lab coat. Nano technologies problem, as it has always been, is how to make it rugged enough to survive in the real world.

The Holy Grail Of Energy Storage Achieved


October 28th, 2008

In a stunning breakthrough in energy storage, MIT scientists have found a way to mimic the way plants use photosynthesis to chemically store energy as you will see in the video below.

Nocera and Matthew Kananhave discovered a way to store the sun's energy in a non-toxic liquid. The process involves using the sun's energy to split water into hydrogen and oxygen gases. Later, the oxygen and hydrogen may be recombined inside a fuel cell, creating carbon-free electricity to power a house or a car whether it be day or night.

When electricity, whether from a solar panel or a wind turbine, runs through an electrode, cobalt and phosphate form a thin film on the electrode and oxygen gas is produced. Combined with another catalyst, such as platinum, that can produce hydrogen gas from water, the system can duplicate the water splitting reaction that occurs during photosynthesis.

The process works at room temperature, in neutral pH water, and is easy to set up.

This really is incredible because solar panels can convert sunlight into energy that can now be stored in a non-toxic liquid during the day, then the liquid converted into energy during the night. You can think of the liquid as a type of battery that can be used whenever the solar panel is not producing energy. This effectively eliminates the need for toxic batteries to store energy.

Nocera hopes that within 10 years, homeowners will be able to power their homes in daylight through photovoltaic cells, while using excess solar energy to produce hydrogen and oxygen to power their own household fuel cell. Electricity-by-wire from a central source could be a thing of the past.

James Barber, Ernst Chain Professor of Biochemistry at Imperial College London called the discovery a "giant leap" toward generating clean, carbon-free energy on a massive scale. Barber writes, "This is a major discovery with enormous implications for the future prosperity of humankind. The importance of their discovery cannot be overstated since it opens up the door for developing new technologies for energy production thus reducing our dependence for fossil fuels and addressing the global climate change problem."

The project is part of the MIT Energy Initiative, a program designed to help transform the global energy system to meet the needs of the future and to help build a bridge to that future by improving today’s energy systems.

This project was funded by the National Science Foundation and by the Chesonis Family Foundation, which gave MIT $10 million this spring to launch the Solar Revolution Project, with a goal to make the large scale deployment of solar energy within 10 years.

New Breakthrough Increases Solar Panel Efficiency By 400 Percent


October 27th, 2008

What if you could increase the energy output of a solar panel by 300 to 400 percent for a cost of $2 per solar panel? That's exactly what these Caltech scientists have done.

Current solar concentrators use costly optical equipment to focus sunlight on a solar panel in order to increase the amount of electricity produced. A company by the name of Cool Earth has created a cheaper alternative that works much better.

They have designed a plastic bubble that goes around the solar panel that is pressurized with air. Cool Earth's solar balloon is made from $2 worth of plastic like the kind found in potato chip bags. The air pressure inside the plastic balloon is changed to alter the shape of the bubble to focus the sun's rays onto a solar panel. The plastic bubble boosts electricity generation 300 to 400 times!

Increase Solar Panel Efficiency by 400 Percent

This is huge. You can look at this from various perspectives. Let's say that a solar panel system currently in use will take 10 years to pay for itself. By increasing the output of the solar panel system by 400 times, the amount of time before the system pays for itself drops to an incredible 2.5 years!

Cool Earth plans to move forward with this technology by opening a solar power plant.

"Cool Earth Solar power plants will produce electricity at a cost lower than natural gas-fueled plants. Our innovative solar technology delivers economically as well as environmentally," said Cool Earth Solar Chief Executive Officer, Rob Lamkin.

What Our Sun Really Is


October 27th, 2008

Most people, when they think of the Sun, think of a big round light in the sky. For thousands of years and easily the majority time humans have been on Earth, we have thought of the Sun as pretty much a giant light bulb in the sky.

There's just something awe inspiring to actually see the nuclear processes that take place on the Sun and then realize, hey, what I'm looking at in this video is helping me lower my electricity bill each month! The video below includes rare footage from NASA's vault that most people have never seen.

As for the sound, I think it's stupid. Here's what the group not so Brilliant Noise has to say about the audio, "The soundtrack highlights the hidden forces at play upon the solar surface, by directly translating areas of intensity within the image brightness into layers of audio manipulation and radio frequencies." In otherwords, the Sun doesn't sound like this as some Internet idiots think. Get a brain.

Make Solar Panel


October 25th, 2008

When you hear make solar panel the first thing that probably comes to mind is buying the typical solar panels that are put on a roof with a mounting bracket. With the latest advanced in Thin Film solar technology it is now possible to roll or slide a thin sheet of solar panels on to your roof.

The builder in this video has installed flexible solar panels on his roof. He says that because they are so thin, they are totally in compliance with Florida building code concerning the installation of solar panels on roofs.

If you are interested in buying these type of flexible solar panels, check out these live auctions going on right now

How many dollars would 1 kilowatt make, concerning electricity made by a solar panel?


October 25th, 2008

I would like to be able to calculate how much money I will receive from my power company if I were to make a solar panel and install it for my home and then sell the extra energy it generates back to the power company. I'm looking at my power bill and it seems that what I need to know to calculate this is how much would the power company pay me on a per watt basis.

Not everyone is going to have the same answer because different power companies will pay a different rate. Looking at my bill, I am being charged about 21 cents per kilowatt hour. One kilowatt hour is 1,000 watts per hour. So for every hour you send 1 watt back to the power company, you get 21 / 1000 = $0.021. But not really. What power companies do is to give you credit for what the power costs them only. Using the math above, I found that my power company pays me only 4 cents per kilowatt hour.

On average, you want to make a solar panel system that generates 12,000 KwH per year. To find out how many solar panels you need to buy to achieve this, here is the formula. If you live in California where you have about 8 hours of sunlight a day, then the math is 12,000 / 365.25 days = 32.8542 / 8 = 4.1 Kilowatt of solar panels. So in this case you want to make a 4 Kilowatt solar panel system. This means that if you buy a 120 watt solar panel, you would need 4,000 / 120 = 33 solar panels on your roof.

My friend John has 72 panels on his roof, here is a picture of his house.

Solar energy- does anyone know of a DIY way to make a solar collector and transfer that energy to batteries?


October 25th, 2008

I'm new to learning about solar diy power. I was wondering how I can make some solar panels for my home. What I would like to do is to be able to run a refrigerator off of a battery that is charged by a solar panel. Does anyone have any ideas?

Not a problem and I have the plans for exactly what you need. The first thing you need to do is to get a large battery that can handle the load of a refrigerator. The XPower is a portable power system that produces household electricity for products rated at 1500 watts or less. A clean and quiet alternative to a generator, the XPower integrates a 60 Amp/hour AGM battery with a 1500-watt inverter and produces a 3000-watt surge. This system is built to run a range of appliances such as a standard size refrigerator and microwave oven, and office equipment such as a computer, monitor, and fax machine. It has a built in inverter and even an AC plug in its side so you can plug your refrigerator right into it. Check out the XPower Pack on Amazon at Xantrex Technologies 802-1500 XPower Powerpack 1,500-Watt Portable Backup Power System

Now the next thing you need is a way to charge this battery and that's where a solar panel with a controller come in. Sunforce sells a nice solar panel set up with a rack to put the solar panels on if you don't want to put them on your roof. The Sunforce pack also comes with a 7-amp charge controller so you don't overcharge the battery. It also comes with a 175-watt inverter that you don't need because the XPower Pack already has one but an extra inverter is always something good to have. Check out the Sunforce Solar Charging Kit at Sunforce 50044 60-Watt Solar Charging Kit

So here's how everything works together. You set up the solar panels outside. The solar panels go into the controller. The controller goes into the battery. You then plug your refrigerator into the AC outlet on the battery and you are good to go.

With Hollywood becoming environmentally-friendly….?


October 25th, 2008

Will this lead to the end of big-budget, blockbuster movies and the end of action movies. Will they be replaced by smaller, more family-friendly films that don't require a huge amount of money and resources to produce?

By GARY GENTILE, AP Business Writer

LOS ANGELES - From "green carpets" at awards shows to organic fruit served to actors on sets, Hollywood is going all out to promote itself as being environmentally hip.

But is it all just show?

No amount of public service announcements or celebrities driving hybrid cars can mask the fact that movie and TV production is a gritty industrial operation, consuming enormous amounts of power to feed bright lights, run sophisticated cameras, and feed a cast of thousands.

Studios' back lots host cavernous soundstages that must be air-conditioned to counter the heat produced by decades-old lighting technology. Huge manufacturing facilities consume wood, steel, paint and plastic to build sets that are often torn down and tossed out after filming ends.

The energy guzzling continues on the exhibition side, too, with multiplexes drawing millions of kilowatts to power old-school popcorn makers and clunky film projectors that cash-strapped theater owners are reluctant to replace.

A two-year study released last year by the University of California at Los Angeles concluded that special effects explosions, idling vehicles and diesel generators make the entertainment industry a major Southern California polluter, second only to the oil industry.

Still, financial and public pressures have resulted in many studios expanding their environmental efforts, doing everything from using a biodiesel fuel mixture to run the generators on the set of the Fox show "24" to converting Warner Bros.' enormous set-building facility to solar energy.

"Public consciousness on this issue has changed dramatically," said Kyle Tanger, a principal at Clear Carbon Consulting. "The talent themselves are requesting it from some of the studios. And a lot of these things make economic sense."

Economic benefit can come to studios directly, by switching to more efficient lighting or cooling systems or driving hybrid cars on location, which can save gas. Other projects, such as installing solar power, can take decades to pay off.

But there are other benefits that are harder to quantify. Besides the public relations angle, many performers and other employees want to work with eco-friendly companies, so it also helps in recruiting and retaining employees, Tanger said.

Form and function merged at this year's Primetime Emmy Awards show.

To symbolize its commitment to energy conservation, Fox had wanted to replace the traditional red carpet with a green one.

The tradition-bound Academy of Television Arts and Sciences, which gives the awards, politely said "no."

But the carpet that ended up cushioning the heels of such stars as Sally Field and America Ferrera was made from recycled plastic bottles and later cut into pieces and donated to several local schools.

"No doubt some efforts have been window dressing. But I actually think Hollywood is doing far more than people are giving it credit for," said Terry Tamminen, who served as an adviser to Gov. Arnold Schwarzenegger before starting his own environmental consulting company.

One convenient yet controversial method is the purchase of carbon credits by studios and producers to offset the greenhouse gases from their production activity. The credits attempt to counter such pollution by investing in environmentally friendly projects such as planting trees or funding wind power.

Studios and a growing number of other industries calculate their emissions, then write a check to one of several brokers who funnel the money to projects around the world. The goal is to become carbon neutral by funding activities that reduce an equal amount of emissions.

The 2004 Fox film "The Day After Tomorrow" and last year's Al Gore documentary "An Inconvenient Truth" offset all or some of their pollution. This year's "Evan Almighty," from Universal, donated money to the Conservation Fund to plant 2,000 trees, enough to "zero out" the greenhouse gases produced.

But the practice has come under fire by some who say it is an easy way to avoid the hard work of directly reducing pollution. Others question whether carbon credit payments are actually going to projects that make that much of a difference.

"If you're going to drive around in a big ol' Hummer and then buy carbon offsets to mitigate that, that's like getting drunk on the weekends and throwing some money through the window of an AA meeting and thinking you're doing something," said Ed Begley Jr., who was a poster child for energy conservation long before Al Gore made it trendy.

The Federal Trade Commission, meanwhile, has begun examining claims made by the nascent multimillion-dollar carbon credit industry.

Warner Bros., which bought carbon credits for the 2005 film "Syriana," has also become more aggressive at reducing emissions during all phases of production.

In addition to solar-powered set-building, the studio is recycling sets, using recycled plastic lumber in the construction of some buildings, and printing double-sided scripts where feasible.

Pieces built for the 2001 film "Ocean's 11" now sit in the Santa Monica offices of the National Resources Defense Council. Sets from this year's sequel "Ocean's 13" were donated to decorate the halls of local community colleges.

"You have to start by measuring your own footprint, then reducing it, whether through using alternative fuels, reducing electrical loads or combining trips," said Shelley Billick, vice president of
environmental initiatives at Warner Bros. Entertainment. "It's too easy to write a check, pay thousands of dollars and say, 'I'm climate neutral.'"

Last year, Fox parent News Corp. set a goal of being carbon neutral by 2010.

To further that goal, Fox Broadcasting chose its popular "24" series as a case study and to serve as a model for other television productions.

Diesel generators that power the show's lighting were switched to a mixture that uses 5 percent biodiesel fuel. That percentage will be increased in coming years. The show also has secured energy from solar and wind generation from a local utility for its soundstages.

But News Corp. has a more ambitious goal than simply reducing its own carbon emissions.

"We knew from the beginning that if our goal is to make as many carbon reductions in the world as possible, probably the best way we can do that is through our audiences," said Rachel Webber, director of energy initiatives for News Corp.

The company concluded that worldwide, it produced the equivalent of 641,150 tons of carbon dioxide. But a rough estimate revealed that the people who read its newspapers, watch its TV shows and browse its Web sites use about 7 billion tons.

"That's the greatest potential to reduce carbon, but we have to get our own house in order first," Webber said.

To reach the wider audience, Webber and a climate expert from Harvard University met with show writers and executive producers earlier this year to brainstorm on ways to integrate environmental messages into show plots.

But Webber said Fox is not forcing "tacked on" messages into its shows, but rather offering resources should writers choose to address the issue.

"We can't use this in a way that doesn't fit into the show," Webber said. "It can't be Jack Bauer driving in a car he otherwise wouldn't drive in."

Ultimately, any steps Hollywood takes, big or small, to reduce emissions are positive, Begley said. "There are different shades of green."

How much is it to put Solar power in ? and can you run appliances off of it?


October 25th, 2008

I was recently looking at a home that costs about $6,000 (USD) to build and I want to build one. What is really neat is that they run on solar power and I want to find out more about it and what else runs off the solar system that the house uses. I am so tired of having to pay everything out in utilities and rent to where I end up owning nothing. I live in Louisiana. Here are some pictures of the home I want to build.

build your own solar power system and house

build your own house


solar house



The story about the family that built this home is at http://www.leenks.com/link60723.htm

Can anyone give me any feedback of what is it like to totally live off the grid?

Hi. I live in Montana and myself and many others here are off the grid. Some have the solar power system where they sell the excess power they generate back to the utilities but many are just totally off the grid and don't do this.

This house you mention is great but it is a whole different world and standard of living than what most Americans are use to.

While the website you cite is cute, and the group in the UK that is actually doing these projects is good, the site doesn't tell the whole story. I know, I went there, I've saw some of their projects and other ecological living projects there. Here's the real truth that they don't tell you. The group, not the one man, that built this home is filled with very talented engineers, researchers, tradesmen, etc. that have mad skills and have chosen to apply them in this manner.

This could be a fun and financially rewarding project for you, but I am going to be brutally honest with you. For most people who try something like this, it ends up being their worst nightmare.

My home cost over $350,000 in materials and site work to achieve what I regard as comfortable off the grid living, but that is my standard. There are homes here in Montana that do just fine and they were built for less than $20,000.

What is a good type of solar panel to get for my house?


October 24th, 2008

With the rising cost of my monthly power bill I have decided that I want to put a solar panel(s) on my roof. What parts do I need in addition to the solar panels? Solar power controller? Wires? How do I wire it into my home's electrical system and about how much electricity would I create and save each month? Would the panels pay for themselves over time? Any help you can provide will be much appreciated. Thank you!

You need solar panels. The solar panels plug into a controller so you need a controller. The controller plugs into a battery bank so you need deep cycle batteries. Your battery bank plugs into an inverter which converts the current into AC that can be used in your home so you need an inverter. That's pretty much it. You just basically buy these parts and plug them together. Of course you need mounting racks for your solar panels if you plan on putting them on your roof.

Whether the panels pay for themselves depends on how you finance them. If you do it the way that most people do by going through a professional solar power company, then you are looking at a price tag of about $20,000. With interest on the financing, it will take about 10 - 15 years before you reach the break even point.

If you build and install your own solar panel system, then the price is much cheaper. You can build a solar panel system for about $200. The more panels you use, that price goes up. But if you do it yourself it will pay for itself in a matter of months rather than years. There are a few really good guides on the market that will guide you through the process and tell you exactly how to get solar panels cheap, how to buy cheap recycled deep cycle batteries, and how to wire everything into your home's electrical system. You can see the top two guides reviewed by clicking here on this link solar panel how to guides.
