A single polymer that can be used in both new age plastic electronics as well as plastic solar cells could spell greater cost-savings and open up new design options for electronic and solar cell companies. A*STAR’s IMRE has developed a new polymer that not only produces a high charge mobility of 0.2 cm2/V.s, which is the same value achieved by commercially available semiconducting materials but also has a high solar power conversion efficiency of 6.3%. this makes IMRE’s polymer one of the few that has both these properties. in addition to this, polymers of the same class as IMRE’s, which are those that use thiophene and benzothiadiazole as the building blocks, could only achieve 2.2% power conversion.
“Current polymers are usually good in one aspect or another, either as a good conductor for use in electronics or endowed with high power conversion efficiency – but not both”, said IMRE Senior Scientist, Dr. Chen Zhi Kuan, the principal researcher working on the polymers. “IMRE’s polymer functions not only as a good material to make electronic components, the same material can be used to convert sunlight to electricity efficiently”. The polymer can also be easily applied in roll-to-roll printing techniques which is similar to how newspapers are currently printed making it possible to manufacture large area-scale printed electronics and organic solar cells quickly and cheaply.
With IMRE’s polymer, manufacturers could save cost using just a single bulk resource for making both printed electronics and organic solar cells. The material could also possibly be used in designing new devices where both power harnessing and electronics are needed in a single component. an example of this would be chemical sensors based on organic thin-film transistors and powered by organic solar cells.
“this breakthrough will help speed up the development of plastic electronics and organic solar cells, and make them more readily available in the marketplace,” said Prof Andy Hor, Executive Director of IMRE.
IMRE?s polymer has both high charge mobility and high power conversion efficiency in a single material as opposed to most polymers that have either one or the other, not both – A transmission electron microscopy image of the IMRE polymer, PC71BM film, showing phase separation between the polymer fibres (light) and PC71BM (dark).

Printed electronics often rely on organic materials like polymers that can be easily processed and manufactured as opposed to traditional electronics (or metal electronics) which rely on inorganics such as copper or silicon. The polymers can be made into thinner, lighter and cost-effective electronic components and organic solar cells.
The IMRE team is developing other organic materials-based polymers that can be scaled up to production and integrated easily into organic electronics. these materials can be used to make energy harvesting and low-power consumption devices like low-cost organic solar cells, new flexible display devices, next generation smart labels and RFID tags.
The research and results were recently published in Advanced Materials.

Is it, the Wind Mill applicable in Philippine archipelago to generate electricity power?
Posted by Wind Generator Plans in Windmill Design on August 29, 2011
The high cost of electricity power in the Philippines, I thought wind mills are the answer.
I was about to mention Ilocos but mr. Mctanggol has beaten me to it.
There is, of course, solar energy harnessed by solar arrays.
And more small scale turbines to harness hydraulic power.
We might also look into natural gas, coal mining, etc. etc.
But the best is yet to come. they have this theory that about 38,000 feet below sea level, we have pure deuterium produced by natural fusion. This is not a radioactive thing, but the problem is how to withstand the terrific pressure down there, which might just do a fusion act with the very blood and guts of anyone who goes for it.
Guess that it would be useful, especially on the mountains where the the wind is stronger.
Unfortunately, 8 years ago here in Tagaytay PAGASA had one at their local station. The next time I came, the blades were missing… and when I moved here, the whole thing was gone. Maybe you could ask PAGASA why they did that.
I think wind mills are good to supplement power (like solar panels) but if there is not a regular supply of wind (sun), then it's not reliable.
The price to produce a Kwh of electricity is still higher than from fossil fired plants.
You are correct but, those things are expensive to build. and then some squatter will come by and tear it down and use for fire wood.
we have a few in place and functioning. most notably in the ilocos area

Universal Bioenergy Files Its First Quarter Report — Achieves Revenues of $22.24 Million
Posted by Wind Generator Plans in Windmill Design on August 29, 2011
IRVINE, Calif., Aug 26, 2011 (GlobeNewswire via COMTEX) –Universal Bioenergy inc. /quotes/zigman/489987 UBRG -11.76% , a natural and alternative energy company, announced today that it has filed its first Quarter Report on Form-10Q for the financial results of operations, for the three months ended March 31, 2011 with the Securities and Exchange Commission. The quarterly report was reviewed by its new independent registered public accounting firm, and contains the Company’s financial statements, management’s discussion and analysis (MD&A), and its future plans.
The Company posted record revenues of $22,247,354 for the three months ended March 31, 2011, as compared to $0 for the same period in 2010. Universal incurred losses of $577,034 as compared to $172,872 for the same period ended March 31, 2010. Excluding the value of common stock that was issued for services, and interest expenses which together totaled $478,609, would correspondingly reduce the net loss of $577,034 to an adjusted net loss of $98,425 for the period ending March 31, 2011. an adjusted net loss of $98,425, equals only 0.44% of their total revenues of $22,247,354 for this period.
Universal’s total operating expenses for the three months ended March 31, 2011 were $337,088 as compared to $167,694 for the same period in 2010. its total assets increased $4,074,717, or by 1,390.21% to $4,367,817 for the period ending March 31, 2011, compared to $293,100 for the same period in 2010. this was primarily due to an increase in accounts receivables from the sales of natural gas. Their long-term liabilities are $248,912 for this reporting period, compared to $70,000 for the same period last year.
Universal’s Senior Vice President Solomon Ali says, “We are extremely pleased with the great strides we have made for this first quarter. Our revenues for the first quarter of 2011 grew at a phenomenal rate from the previous year. In 2010 the company achieved revenues of $41,320,647 for the entire year. however, during the first three months of 2011 alone, we generated revenues of $22,247,354, or 54% of the total revenues for all of 2010. this is a monumental increase for a company in any industry. Many companies are considered high growth companies if their revenues increase by 10% to 15% annually. at a 54% growth rate, we have already exceeded that benchmark by nearly four times, which means we are a hyper growth company right now. We look forward to continued rapid growth, with more and larger contract awards for the sales of natural gas, propane and other energy products. Our goal is to generate even greater revenues and move the company to solid profitability, to the benefit of our shareholders.”

Do guys ever pass loud s*x air noises through their urethra?
Posted by Wind Generator Plans in Windmill Design on August 29, 2011
You know from doggy-style suction?
Not from doggy suction, but remember the time that you thought the term "bl0w job" was meant to be taken literally? Yeah, well…
As a new Zealander I can tell you definitively that it doesn't happen with sheep.
lol no. btw, "sex air" as you put it, is always good for a little comic relief.
i believe that this is correctly categorized.
This question made me queef. And I do believe it is in the correct category as air leaves the passage way and travels outward.
Can you smell it from here, btw?
I dunno but I loved her song, R-E-S-P-E-C-T. I didn't think she made funny noises. most people think she has a great voice. Maybe you're thinking of Madonna?
Hmmmm… my ol' man used to do 'that' before I understood that "blowing" had absolutely nothing to do with a B.J.
THIGH PASS SEVEN AIR NOISES OUT OF THE WB (NOT SIX), ONE FOR EACH CREATION DAY AND ONE FOR THE SABBATH.
being a boy of course it takess ther form of an elongated Tweeeeeeeeet
EDIT: Oh my goodness an honest Kiiwi
lol, no I don't think so, at least I never have.
((((Goodies))))
There is nothing left to say.this question says it all.

How renewable energy solar power works?
Posted by Wind Generator Plans in Windmill Design on August 29, 2011
My father is asking me to post a question about this.He is planning to buy an alternative renewable energy resources.Is it true that you will save electricity from alternative home energy solutions? any suggestions and help on this post is highly appreciated thanks.
Simply put: Solar Panels are built to collect UV rays from Sun and the UV rays are converted by the solar panel to electricity that can be used to power your light bulbs, refrigerators, stoves and other electrical appliances.
Some appliances use direct current (DC) from the Sun. Such appliances can be powered directly by electricity emanating from the solar panel (or pvc panels). most appliances works only with alternating current (AC) and therefore you need an Inverter to change the current from the solar panel from DC to AC. You may need a battery too to store energy for sun down and night times. For list of what you may need go to the source site referenced below.
For cost: You can get a lot of used materials (e.g. through eBay) to build your solar electricity system.
Solar energy is very promising because it is renewable, which means that you can continue getting the power you need nonstop. the sun provides a large amount of energy that artificial units cannot sufficiently give. the small part of the power stems through to the earth in the form of sunlight. the rays that deliver the energy of the sun give both heat and power that can effectively be gathered and changed to other types of energy, such as electricity. Solar steam generators use solar power generation use the power of the sun to heat water and create steam to let electrical turbines work.
Another popular method of solar power generation is through the use of photovoltaic devices. the devices are made to use photovoltaic cells or solar cells to transform solar energy into DC electricity. There are plenty of ways to collect solar energy such as through parabolic troughs, solar panels, solar dishes and solar power towers that have reflecting mirrors. A number of solar collectors are categorized as either concentrating or non-concentrating.
There's a free report how you can make your own solar power and other useful info about solar power in the links below
A solar panel is made of a series of photovoltaic cells. These convert sunlight into electricity. each panel has a rated output in watts, under ideal conditions. Generally, the higher the wattage rating, the larger and more expensive the panel.
It's worth noting that few people have ideal conditions either. Ideal solar conditions are considered to be a bright, cloudless sunny day, at sea level, at the equator. Sunlight in those conditions yields 1000 watts per square yard. but few people live in such a place, and if your local conditions are only at 40% of optimal, your 200 watt panel will only produce 80 watts.
You'll need to figure out what the total power draw of your home is; Lights, heating, cooling, appliances, entertainment system, washer & dryer, etc. You may end up investing in more efficient appliances, since new appliances are almost always cheaper than more solar capacity.
You'll also need other things in addition to the panels. Batteries (unless you only want your lights and heat to work during the day), transformers, power controllers, and so forth. I've included a link to a website that sells everything you need.
It's basically a panel of millions of solar cells (photons) that have this amazing ability to convert UV rays into electricity. the electricity is captured by wires embedded in the panels and sent through a main cable, where it goes wherever you need it to go. the cells are extremely expensive when used in large projects (such as a house), but ultimately pay off. I have friends that actually sell their excess energy from their solar panels to the electric company, and get a pay check from them every month (keep in mind though, they live in a desert climate).
I would suggest waiting before buying though. the technology is bound to become more efficient and affordable with the amount of research going into this field. Wait before you end up buying thousands of dollars worth of solar equipment only to have them become obsolete in a few years.
Solar electricity panels consist of 2 different types of semiconductor stuck together. one has excess electrons, one has few electrons. When they stick together the electrons go from the excess electron side and stick to ions in the other side, creating an electric field.
When light hits a semiconductor, electrons are knocked off atoms and can move about the crystal. in a solar cell, you have an electric field (as explained above) and the electrons are pushed in one direction. Electrons moving in one direction = electricity!
They are currently very expensive and unless you have very expensive electricity or the government gives you subsidies then they're probably not worth buying. Germany and the UK now have 'Feed in Tariffs' that pay you loads of money and make them worthwhile.
You need a panel and an inverter. the inverter turns the DC electricity from the panel into AC electricity you can use in the home. When it's sunny your panels will make electricity that you can use – if you can't use it then you may have either 'grid tie' the system which sends the extra electricity into the grid and your power company will pay you for it. otherwise you can have batteries which store the electricity for you to use at a later date.
In general, 'grid tie' systems are better because batteries cost lots and you don't necessarily get bad rates for your solar electricity if you sell off the stuff you're not using.
First when talking about Solar we need to discuss the different applications. There is Solar electric called Photo-voltaic or PV for short. There are several types here to but mostly they work the same. When the sun hits the panel it starts electrons in motion which creates DC current. here you have the option to convert it to AC by way of an inverter or use DC appliances. the main difference in the different types is efficiency and new technology is creating more efficient panels as we speak.
Solar thermal use the sun's heat to create thermal energy (heat) for water. You may hear it called Solar Hot Water. When I started installing Solar we called these DHW (domestic hot water) systems. These panels are either a flat plate glazed, evacuated tube, or a plastic panel (used to heat swimming pools.)
The best thing you can do is use a combination of alternative energy sources! because you cannot rely on just 1. look into backyard wind turbines, solar roof panels, and even hydroelectricity!
Recently, a new design of the traditional wind turbine has been introduced. it is safer for birds and looks nicer. It's called the Windspire.
http://windspireenergy.com/purchase/find…
I am from India. Though here it is illegal to use alternative energy sources at home, without notifying it to the government. in us, i dnt have any idea about this. but yeah, it does help wen the main source suppy is off. usually alternative enery sources are cheaper and benificial to use at home, but ya..it can take time more than usual/ Like cookin food in solar cooker can take 45 minutes, where as in LPG, or natural gas.. it takes just 10 minutes. So if one is looking to keep a backup//its very useful at times.
There are several types of solar systems; solar water heating, grid-tied solar electric, off-grid solar electric, grid tied solar electric with battery backup. You get the idea. Different types are good for different situations.
I highly recommend starting with a solar water heating system. this provides up to 75% of your hot water, rather than heating it all with your electric, gas, or oil water heater. it preheats the water so your water heater has to work much much less, saving you a lot of energy, depending on how you heat your water, up to 30% of your current energy use.
Next I suggest energy conservation. the best way to save money on your electric bill is to use less. For every $1 you spend on conservation, that's equal to about $4 of solar. Much cheaper to save electricity than to make it.
Then look into a grid-tied solar electric system. this will allow you to make some power, based on how much money you want to spend on the system, and continue buying the rest from the electric company. that way you don't have to have a huge system with batteries.
Get your electric bill out and see how many kilowatt hours (kwh) you currently use. Enter it in a grid-tied calculator like this one, (for the USA) http://www.altestore.com/howto/Tools-Cal… it will help you determine how much it will cost and how much you will save. There are tax incentives available in many countries to help pay for the systems. if you are not in the USA, you can try a calculator like this one that shows what size system needed, and then find out how much per watt installations cost in your area (it's about $7 a watt here in the USA). http://www.altestore.com/store/calculato…
Also have your dad watch a couple of these free videos. they are are a great way for homeowners to learn the basics of solar, so you know what is required when hiring someone to install it. http://www.altestore.com/store/Books-Cla…
Here are some great links to help you find all the answers you need:
http://en.wikipedia.org/wiki/Renewable_e…
http://en.wikipedia.org/wiki/Alternative…
http://en.wikipedia.org/wiki/Solar_panel…
http://en.wikipedia.org/wiki/Solar_power
I think it is a great way to go. When I have my own place I will be placing some solar power panels on my roof that is for sure.
Well tell your dad solar is a great thing but learn how to build his own . they really are simple to build with a little practice . I get all my supplies such as solar cells off eBay really cheap and there all new . the dealers on there will even give you step by step instructions for free if you ask . What cost people $30,000 i build myself for a little over $3000 .
Renewable energy solar power is much more than an alternative energy. it saves lot of energy compared to other sources. Installation of this system is also comparatively easy as well as cost effective one.

I am looking for some website or forum where I can discuss the nitty-gritty of making wind turbines and building anything that enables people to go off the grid and build their own boats, heat sources, alternative fuels, all-natural materials, etc.
Would anyone know where to find that?
Thanks.

i hve a mechanics project in wich i need to design a windmill operated device and d design must be original. so plz can u suggest sme devices or as to how windmill can b used to solve a problem at hand
"The design must be original" is a real problem. Windmills have been used for centuries to grind corn or wheat, and pump water, and for nearly a hundred years at least to generate electricity.
Perhaps you could be original by making the design more specific – for example, designing a windmill that would charge an iPod when you blew on the fan?
Ameresco: Clean Energy One-Stop Shop
Posted by Wind Generator Plans in Windmill Design on August 28, 2011
Contrary to common belief, the greatest barrier to the adoption of clean energy is not the cost. In many cases, cost is not a barrier at all: it’s an advantage. That’s because energy efficiency measures are usually so cost-effective that they not only pay for themselves, they can often pay for the addition of flashier clean energy technologies such as solar and wind.
For institutions in the Federal and MUSH (Municipalities, Universities, Schools, and Hospitals) sectors, the main barriers are lack of capital and expertise. Lack of capital arises because such institutions traditionally consider energy to be an operating expense, not a capital expense, while clean energy projects usually require an initial capital expenditure in return for ongoing energy savings. Lack of expertise arises simply because finding the best energy solutions is far from simple. although there are many simple measures that an interested amateur can take, the greatest savings come from considering buildings and other facilities as integrated systems, not as collections of isolated measures.
Energy Service Companies
Ameresco, inc. (NYSE:AMRC) was founded in 2000 as an independent, one-stop shop to help Federal and MUSH institutions overcome these barriers. Last week, I interviewed Ameresco President and CEO George Sakellaris as part of my series of articles on energy service stocks. Sakellaris pioneered this Energy Service Company (ESCO) model while working for New England Electric System to help industrial customers reduce their power usage in 1979. Before founding Ameresco, he founded another leading ESCO, Noresco in 1989, which is currently owned by Carrier, a division of United Technologies (NYSE:UTX).
I first became interested in the ESCO model (also known as performance contracting) in 2007, when I heard about it as part of a Western Governor’s Association Workshop on Efficient Buildings. Then, as now, most ESCOs are arms of larger technology companies, like Noresco mentioned above, or are part of energy companies and utilities. other publicly traded companies with ESCO arms include AECOM (NYSE:ACM), Honeywell (NYSE:HON), Chevron (NYSE:CVX), Consolidated Edison (NYSE:ED), Constellation (NYSE:CEG), Eaton (NYSE:ETN), NextEra (NYSE:NEE), Johnson Controls(NYSE:JCI), Schneider Electric (Paris:SU), and Ingersoll-Rand (NYSE:IR).
In contrast, Ameresco is independent of any equipment manufacturer or energy company, leaving them technology-agnostic and able to approach the solution from the customer’s perspective. This independence, along with previous customer satisfaction and Ameresco’s wide expertise allows the company to win bids such as the $795 million contract to build biomass cogeneration and heating facilities at the Department of Energy’s Savannah River Site in South Carolina over the course of 19 years. According to Sakellaris, Ameresco won this contract (the largest renewable energy performance contract so far in the United States) without being the lowest cost bidder because of their expertise and independence. He also says Ameresco can compete on price because of low overhead.
Financial Results
The combination of a strong brand and expertise along with low overhead have contributed to strong results. Annual revenue has grown steadily from $278 million in 2006 to $618 million in 2010, with second quarter revenue up 17% on a year earlier, matching the last five year’s compound annual growth rate (CAGR). over the same period, earnings per share have risen at a 21% CAGR. at the current stock price of $10.34, AMRC has a trailing P/E ratio of 14.35, which is modest considering the consensus 20% long term expected growth rate.
Why doesn't your home use solar, wind or other renewable energies?
Posted by Wind Generator Plans in Windmill Design on August 28, 2011
The good folks dedicating their careers (lives) to studying, inventing and engineering these sources of energy are being stomped on by oil companies who want to keep selling their products. another reason is that solar is still pretty expensive for the typical home owner (a system producing $500 worth of electricity costs about $30,000 or more in CA) and wind equipment is still pretty big – the blade diameter on a windmill to generate a good fraction of the energy needed for a family of 4 is too big to look good in a typical neighborhood.
inefficient and expensive.
ask the big companies why that is.. willya?
ask big OIL and those huge ELECTRIC companies that run/operate those grids…
see what happens.
my house does too.
we use 8 solar panels.
maybe you should do a little more research first, son.
mine does, i've got the best power source ever
We would, but we live in a heavily wooded area, so direct sunlight is only in certain portions of the yard, let alone the house. plus, trees and houses are so close together that a wind machine would not be feasible.
We do however keep energy use to a minimum during the day and at night, preferring to keep the air/heat off when not needed, and lighting candles at night to get a glass of water etc.
There are about 50 ways to cut down on power usage in a house, from stopping drafts in doors and windows, to just learning to wear a sweater indoors in the winter to avoid using more heating oil or natural gas, or electricity for your heaters. Even if you can't rely on a renewable, you can still minimize your use of fossile fuels and electricity without having to give up much in the way of comfort.
I have two homes and burn wood for heat in one of them. that is a renewable energy source.
Unfortunately, the two homes are poorly situated for solar and wind energy. Both are extensively surrounded by trees that block a southern view. I did buy a wind generator for an older house but the manufacturer went out of business before the machine was completed. I lost a bunch of money on that.
At this point in time, I can't afford the capital investment of $30,000 to install a solar voltaic system. considering my utility rates, the return on investment doesn't look good, taking over 25 years to pay for itself. I am, however, interested in some form of solar water-heating system that will work in conjunction with my electric hot water heater.
