This feedback is crucial for building the best possible Solar Energy community. Your feedback is greatly appreciated. **Please DO NOT email with solar questions. They will go unanswered. All solar questions must be posted on the forum for everyone’s benefit. Thank you. 10-26-2010 06:14 PM – MarineLiner To me, “very” positive. Still like more the green color. Email will be sent with more feedback. 10-27-2010 07:33 AM – Jason Thanks Marineliner, however, the green would be a dramatic change, and people were saying it was too bright on their screens and annoying to look at. The current colors are easy on the eyes, which is important because people are on here for long periods of time. 03-09-2011 07:29 PM – MarineLiner Updates on the latest solar energy news We need updates on the latest solar energy news. But, unfortunately, someone make used by advertising their facebook account. A very smart action had taken by Mike. It is: 04-07-2011 08:13 PM – Swampwood I get the lots of neg attitude, afraid to ask questions feeling here. 04-07-2011 08:34 PM – russ Hi Swampwood – The guy is throwing a tantrum as he thinks he should dictate what is going on. He has been warned for the last time. Ask your questions – no problem. Russ 05-17-2011 03:54 AM – dvhenry I see the mods here must be kept busy just deleting spam, I just noticed the latest one, with 10 in 5 minutes! Are you guys running a spam posting contest you have not told us about? 05-17-2011 03:59 AM – russ Today there have been several that were absolute spammers – China based for the most part. Also a few links were removed. Just for the record – members that contribute may be allowed to post links – many in the industry have excellent and in depth knowledge that is very helpful to others. A one line or short paragraph that says little doe not qualify. Russ 05-17-2011 04:26 AM – dvhenry You’re doing a good job, if they were allowed to post spam unchecked these forums would soon become frustrating to visit. 06-25-2011 09:55 PM – healthawareness negative effects of solar energy – on home I have been doing some research on solar power and the potential health risks associated with placing solar panels on your home – many have concerns. Aside from all the dangerous chemicals and materials that go in to the manufacturing of the solar panels, silicon hydrocholoride is one that produces silicon dust – which is extremely dangerous to the respiratory system. Obviously, there are also background levels of radiation, and negative e. vibration from these panels which also pose health risks. We all want to contribute to energy efficiency and save money on energy costs, but we all need to be aware of health concerns. I suggest that anyone considering solar panels on their home should reasearch the following: 1) What chemicals are used in the manufacturing of solar panels 2) How long do the panels last, and what methods of disposal are used after the lifetime of the panels? They are a serious toxic waste after use. Look at Japan. 3) What levels of radiation and negative energy are being emitted from panels, exp. 4) Dangers – surges etc., google – health risks of installing solar panels on home – solar panels and dangers to health – manufacturing and disposal of solar panels Although there are serious health risks in considering these, they are not discussed when promoting energy savings. Be pro-active – dig deeper for the right information and protect your health and the environment. 06-25-2011 10:04 PM – russ Healthawareness – This is the typical green BS & blather that comes about when people parrot what they are told rather than think. If you are so concerned I suggest you just hide under a rock and don’t eat or drink anything – the problem will be resolved shortly. You can search anything and come up with horror stories – posted by people like you and your little friends. Often they are posted by a concerned scientist or environmentalist – both terms are meaningless without an individuals name attached.

All education and knowledge comes from what people read, are taught, and their learning experiences, not “What they Think” as you put it. The information I wanted to share came from FACT. It is not what I came up with. Many people were concerned about whether or not there were any side effects for using solar panels. I certainly am far from hiding under a rock. I am well educated, with two university degrees, two years of college, five years education in Alternative Medicine, was a Social Worker for 25 years, qualified as a personal trainer, fitness instructor and Nutritionist, and feel justified in stating that any information that I have given is accurate. I am far from naive. Where do you get off making any reference to “my little friends” etc.? You must be some crazy, uneducated person who is in the business of selling solar panels, or perhaps have some vested interest, like working for one of the energy companies that is pushing them. Why don’t you offer some helpful, knowledgeable information to this panel if you have any rather than offensive criticism? Either that, or crawl back to where you belong. 06-27-2011 08:58 PM – russ Originally Posted by healthawareness This reply is for Russ!

New solar technology boasts higher efficiency than other solar thermal systems

Chris Meehan
MAY 03, 2011
By now, most of us know the term photovoltaic—solar radiation converting sunlight into electricity—but there’s a new term we might need to become familiar with: thermoelectric, the process of directly converting heat from the sun, or other sources, into electricity.
A team of researchers at Boston College and the Massachusetts Institute of Technology (MIT) are creating high-efficiency solar thermoelectric devices, which convert the sun’s heat into electricity.
Thermoelectric sounds like another solar technology that’s increasingly gaining popularity—solar thermal—but it’s different. Solar thermal projects concentrate sunlight on a fixed point and uses a medium to move the stored heat energy to a place where it can be converted into electricity by superheating water into steam and using the steam to turn a turbine that generates electricity—ultimately the same process that natural gas and coal-fired power plants use to generate electricity.
But the thermoelectric method converts sunlight directly into electricity, without needing a secondary thermal conductor.
The device won’t be on your rooftop tomorrow, but the research is promising, producing a device that could both provide electricity and hot water for homes, residences and more, according to the researchers.
The team used nanomaterials and an optical concentrator to focus sunlight on the device, and they coupled it with a hot-water heater to cool the thermoelectric aspect of the device to keep it producing electricity efficiently.
The team of MIT and Boston College researchers have developed a device that converts solar thermal heat into electricity at a higher efficiency rate than previously possible—and also heats water.
“We first collect the Sun’s radiation and convert it into heat, and immediately convert the heat into electricity via thermoelectric materials,” said Boston College Professor of Physics Zhifeng Ren. “For efficient electricity conversion using thermoelectric materials, we need to cool them, that’s where the hot water is generated.”
Ren and the team of researchers published their work, “High-performance flat-panel solar thermoelectric generators with high thermal concentration,” in Nature Materials this week.
The device they’ve developed encases a thermoelectric device in a vacuum to increase its efficiency, according to Ren.
“Our electricity generation is 7 to 8 times [higher than] the previous record due to better thermoelectric materials, thermal concentration and operation in vacuum,” he said.
Photovoltaics only provide power from the sun’s visible spectrum of radiation. The thermoelectric devices use the range of the sun’s spectra.
“It captures the whole solar spectra and converts it into heat through the selective surface and then converts the heat into electricity via thermoelectric materials,” he said.
