Google Plans New Solar Mirror Technology

Google’s Bill Weihl expresses his opinion, “We see a chance to make a difference in the field of renewable energy and energy information that can help bring the world to a lower carbon and more efficient economy.” Google is known for its Internet search engine lenovo thinkpad z60m 2529 battery. Now they want to make inroads into green technology too. They declared in 2007 that they want to invest in clean and green technology and want to do research of their own in the field of alternative energy. Now Google’s engineers are putting their effort and energy into solar technology. We all know that solar power is clean and green fuel. But the cost of solar panels prevents us from utilizing solar energy extensively. Now Google Inc. is trying to come up with its own solar panel with a reduced cost of 25%.

They are developing a new mirror technology for cheaper solar power. Weihl confirms, “Typically what we’re seeing is $2.50 to $4 a watt (for) capital cost. So a 250 megawatt installation would be $600 million to a $1 billion. It’s a lot of money.” That amounts to 12 to 18 cents a kilowatt/hour. They are using solar energy to heat up a substance that produces steam. This steam will turn the wheels of turbines. Mirrors will start the whole process by directing the sun’s rays on the substance to heat it up. Bill Weihl reaffirms his company’s commitment, “We’ve been looking at very unusual materials for the mirrors both for the reflective surface as well as the substrate that the mirror is mounted on lenovo ideapad y450 battery.”

Weihl said Google is trying to reduce the cost of making heliostats, the fields of mirrors that have to track the sun, by at least a factor of two, “ideally a factor of three or four.”

Google is trying to develop a feasible technology in a couple of months to show internally. They are also opting for the accelerated testing so that they can find out the impact of decades of wear and tear on the new mirrors while they are installed in desert. Bill Weihl confirms, “We’re not there yet. I’m very hopeful we will have mirrors that are cheaper than what companies in the space are using…”

Google is also going for another technology — gas turbines — that would derive energy from solar power rather than natural gas. This will help Google office to reduce their electricity bill further.

Weihl shares his enthusiasm for future power generation, “In two to three years we could be demonstrating a significant scale pilot system that would generate a lot of power and would be clearly mass manufacturable at a cost that would give us a levelized cost of electricity that would be in the 5 cents or sub 5 cents a kilowatt hour range.”

Google is aiming to make the alternative form of energy cheaper than the energy generated from coal. Earlier Google was investing in other green companies. But later on they decided to develop their own clean and green technology. They discovered that most of the companies lack innovative ideas to replace dependence on fossil fuels. That’s why they are actively involved in coming up with their own new green technology.

First, Google people have put their own house in order. Goggle’s data centers make sure that 300 million web searches take place smoothly. But these searches translate into huge costs as they devour mammoth amount of electricity. Google put his team of intellectuals to come up with more efficient and less power consuming designs. This step reduced the servers’ consumption of energy by half. Google’s Mountain View, California, headquarters installed solar panels producing 1.6 MW of solar energy. Their carefully selected carbon offsets, has helped the company become carbon-neutral. According to Weihl the side effects are quite pleasant, “In the process we’re saving ourselves a lot of money by making ourselves more efficient.”

DIY Solar Setup

by admin on Jun.21, 2010, under Uncategorized

This instructable will tell you how I went about building a 12v Solar setup to run my Air Cooler during our hot Summer and a 12v 120 litre Fridge/Freezer during the cooler months.It will include some of the things I got right and the things I got wrong while building my “Sun Suckers”.Please keep in mind that I am not qualified in this area and that my methods were based on a “research then trial and error” system.Please use the ideas presented as a guide and improve on them wherever you can.I won’t be covering “in detail” panel building as such but will include helpful stuff (mostly discovered by the afore mentioned “trial and error’ ) that wasn’t covered in the many panel building Instructables and articles I read while doing my research.

Get The LED Out Contest.I’ve entered this ‘ible in the above contest because the Solar Tracker relies entirely on 2 LED’s to do it’s work. The LED’s are directly responsible for adding approximately 40% to the systems output. If either of the LED’s were to fail the Tracker would not work.
Learning. Think beyond today.If you spend as much time as I did scouring the web for every bit of information available you’ll probably get as confused as I did at first. There’s a lot of good info out there but there’s a lot of rubbish too. As a rule of thumb the greater the number of people say something, the more likely it is to be correct. Usually. But not always. There are already some “Instr…
Choose your materials wisely.This is the most critical step. As mentioned earlier, the materials you choose to construct your panels with will determine it’s lifespan. Don’t shortchange your Panels like I did mine There are commercial products available for mounting Pre Tabbed Cells which include “Tedlar”(R) http://www2.dupont.com/Photovoltaics/en_US/products_services/backsheet/tedlarPVF.html .…
Wots Watts?? Tabs?? Which Cells to buy?? Soldering Iron?? Solder??Watts are calculated by multiplying the voltage of the cell by its rated amperage. Simple. Well not really. The formula for say……a panel built using 35 0.55 volt, 3.6 amp cells would be this: Voltage of each cell (0.55 v) X rated Amperage of each cell (3.6 a) X 35 cells = 69.3 Watts . A nice sized panel and well worth the effort. Smaller amperage cells are ob…
Before you Solder.The Cells need to be soldered together in what is called Series , that is, the positive side of each cell connected by tab wire to the negative side of its neighbour (see diagram) To achieve this the (untabbed) Cells all need to be tabbed, that is to have flat Tab wire soldered to the front (negative) side and then to the back (positive) side. The Solder . Buy a roll…
Soldering the Tab Wire to the Cells.This is where all that Soldering practice will pay big dividends. Depending on the cells you’ve bought and the type of panel you’re building you may need to solder Tab wire to the Front, the Back or both. Front busses take more work so I like to do them first. UnfortunatelyI don’t have any pics of the process. Ok….your Irons hot so lets go! Apply a small amount of…
Choosing Your Construction Materials.Parts of this step are pretty much a repeat of an earlier step. I have done this to emphasize the importance of materials choice. If you can afford it go for the Tedlar products and the best non reflective glass you can get your hands on and follow the instructions that come with the Tedlar materials. The end product can be mounted on a timber or metal frame. If y…
Building Your Panels.My blog at is pretty much a description of my Panel Building experiences from my first few Panels. In it I give details on joining cells correctly and constructing panels on a tight budget.
After the Panels are Built.Now that you have built and tested your panel/s you need to harness all that Free electricity you’re suddenly producing. Solar Controller. The Controller is the brains of the system. Your panels charge your batteries through it and it supplies that power to your appliances. It controls the amount of charge that goes to your Battery Bank and protects your batteries f…
The LED Solar Tracker.Your Solar Panels will produce much (30 to 60%) more electricity when they’re kept pointing directly at the Sun as opposed to sitting in the one position all the time. To achieve this you need to buy or build a Solar Tracker and mount your panels on it. You have 2 choices here….you can opt for a “Dual Axis” tracker that will follow the Sun from East to West then, when the …

Trojan Battery company supply deep-cycle batteries dole out energy steady

by admin on Jun.01, 2010, under Battery news, battery tips, electronics news, laptop battery, notebook

For 85 years, Trojan Battery Co., now the top U.S. provider of batteries for electric golf carts, has had a quiet actuality as a family-owned and operated company.

But from the calm of manicured fairways, the Santa Fe Springs close has been advance into the all-embracing blooming movement. The company’s specialty is deep-cycle batteries that allotment out activity in a abiding beck over almost continued periods of time ¡ª just what’s bare for solar ability systems in limited locations of the world.

“The accouchement can abstraction bigger afterwards the sun goes down,” he said. “They’re not breath in kerosene effluvium anymore.” The company’s amplification into the apple amphitheatre has fatigued the absorption of the Obama administration’s National Export Initiative, which seeks to bifold U.S. exports in the next 5 years (more : Dell C1295 battery, Dell CF623 battery, Dell FK890 battery).

But the aisle from stateside to all-embracing supplier was not a bland one for the aggregation founded in 1925 by George Godber, who formed on batteries in Navy submarines during Apple War I. The co-founder was Godber’s brother-in-law, Carl Speer, who had been a affiliate of USC’s aboriginal football aggregation ¡ª appropriately the name of the firm. Currently, the aggregation says it food the batteries for a array of golf carts acclimated on 98 percent of top U.S. courses.

Trojan aswell makes batteries for added uses, including watering systems, attic polishers and solar systems at its factories in Santa Fe Springs and two locales in Georgia ¡ª Lithonia, just alfresco Atlanta, and Sandersville, abreast Macon. Bryan Godber ¡ª George’s grandson and now Trojan’s carnality admiral for renewable activity ¡ª said the United States Commercial Service was “providing us with letters on abeyant customers, talking us through the bazaar dynamics (more : Dell GD761 battery, Dell GK479 battery).”

For a aggregation that hardly ventured alfresco its home country, the abetment was invaluable. “How abroad would we apperceive who it was safe to do business with?” Godber said. Trojan admiral went on a cruise to India in which they met with 15 -to-be audience in Chennai, Mumbai and Hyderabad over the advance of just 5 days.

The abeyant for advance for companies in this acreage are vast, said Jock O’Connell, all-embracing barter and economics adviser at the University of California Center in Sacramento. “So abundant of the apple ¡ª locations of India, Pakistan, China and Africa ¡ª is off the grid,” O’Connell said. “Some of the fastest-growing markets for cellphones are aswell in India and Africa, and they all accept to be charged.

“If you can advice humans off the filigree adore the allowances of getting on the grid, you accept a advantageous bazaar there.” That bazaar has aswell provided new activity to the company. Just three years ago, Trojan had about 700 employees. Then the recession hit, and it fell to 500 ¡ª a bead of added than 25 percent.

the ADB launched renewable energy

by admin on May.05, 2010, under Battery news, battery tips, electronics news, laptop battery

Renewable-Energy-Standard

The Asian Development Bank (ADB) has this week launched an ambitious renewable energy project designed to attract billions of dollars of private investment and deploy around three gigawatts of solar power across the Asia and Pacific region within the next three years.As well as providing direct financing and stimulating private sector investment, ASEI is hoping to raise $500m from donor countries in order to reduce the high up-front capital costs of investing in solar energy.

The ADB failed to privde many specific details about the ASEI scheme, revealing only that the scheme aims to identify and develop large capacity solar projects across the region capable of generate 3GW of solar power by 2012.

The scheme will also establish and host an international knowledge-sharing platform known as the Solar Energy Forum, that will track solar development projects, discuss new solar power proposals and incentive mechanisms.

he bank said it hopes to attract investment from commercial banks and the private sector by making available a range of pre-approved projects through the ASEI. It added that it would also encourage “knowledge sharing” between the bank and private investors and develop new financial mechanisms designed to attract externtal investment.
