Researchers at Michigan State University have created a fully transparent solar concentrator, which could turn any window or sheet of glass (like your smartphone’s screen) into a photovoltaic solar cell. Unlike other “transparent” solar cells that we’ve reported on in the past, this one really is transparent, as you can see in the photos throughout this story. According to Richard Lunt, who led the research, the team are confident that
The sone is a unit of how loud a sound is perceived. The sone scale is linear. Doubling the perceived loudness doubles the sone value. In acoustics, loudness is the subjective perception of sound pressure. The study of apparent loudness is included in the topic of psychoacoustics and employs methods of psychophysics <wikipedia>. GOOGLE DEFINITION: What is a sone? A sone is a measure of loudness. The higher the sone
NOTE: SolarRoyal LLC recommends utilizing an insured, bonded and licensed electrician. Prior to opening the breaker panel MAKE CERTAIN THE MAIN BREAKER IS IN THE OFF POSITION. Secure the two red leads (wires) of the unit to the two (2x) 20amp breakers (one on each terminal and preferably at the bottom of each leg). Secure the green wire from the unit to the ground bar
Ultra-high efficiency solar cells similar to those used in space may now be possible on your rooftop thanks to a new microscale solar concentration technology developed by an international team of researchers. "Concentrating photovoltaic (CPV) systems leverage the cost of high efficiency multi-junction solar cells by using inexpensive optics to concentrate sunlight onto them," said Noel C. Giebink, assistant professor of electrical engineering, Penn State. "Current CPV systems are the

Robust & Extreme ConditionsJust in case you were wondering how well the Solar Royal (SR1800 Series) solar attic fan (ventilation fan) stacks up, we just received KUDOS via the following video testimonial on how our ventilation solution works even when covered in snow.This is what you can expect from a high-quality monocrystaline solar panel and high-efficiency brushless motor from Solar Royal.
CLICK TO VIEWDARE TO COMPARE: we have earned countless customers around the nation with our 'Dare -to- Compare' campaign which is fundamentally pushing our potential customer to ask questions and take the time to compare the differences if they are considering anything other then a Solar Royal solar attic ventilation fan.
- High quality monocrysataline solar panel
- High efficiency brushless (variable speed) DC motor
- Easily upgradeable via our external power-expansion port (add 25Watt Remote Solar Panel)
Since the final gavel fell at the Lima climate talks earlier this month, discussions have centred on one question: what did the talks actually accomplish? After two weeks of intense negotiation, governments settled on a draft text that will hopefully lead to a successful global climate deal in Paris next December. While opinions vary regarding the success or failure of the outcome, there is another story emerging outside the negotiation
Solar panels embedded in the cycle path near Amsterdam could generate enough electricity to power three houses, with potential to extend scheme to roads The bike path that connects the Amsterdam suburbs of Krommenie and Wormerveer is popular with both school children and commuters: around 2,000 cyclists ride its two lanes on an average day. But next week Krommenie’s cycle path promises to become even more useful: on 12 November
Could a long-vacant cigarette factory in North Carolina build the rechargeable solar energy battery that will unlock the future of the clean energy economy? The Swiss-based Alevo Group launched the new battery technology on Tuesday. After spending $68.5m (£42.5m) for the factory, the group said it would spend up to $1bn to develop a system that would get rid of waste on the grid and expand the use of wind
