New York City Area Doubled Its Solar Power Capacity in 2010

nyc-roof-solar
Private solar power installations at homes and fda approved viagra businesses more than doubled last year in New York City and Westchester County.  In 2009, 134 PV systems were installed in that area and solar power capacity was 4 MW.  Last year, there were 203 PV installations, bringing the capacity up to 8.5 MW.

Westchester County installations actually fell slightly from 2009, but the New York City boroughs ramped up their solar.  Queens actually quadrupled its installations from 16 in 2009 to 64 in 2010, adding over 1,538 kW of capacity.

Utility company Con Edison is taking the credit for the solar boom saying they promoted the economic and environmental benefits of solar power systems and also streamlined the approval process for residential systems under 25 kW.

The number of small-scale solar installations has grown more rapidly than larger solar projects recently, mainly due to the where buy viagra economic downturn and the high price of larger installations, but also because the approval process for large projects can be a nightmare for developers.  While small, distributed installations won't solve the climate crisis on their own, they are an essential part of cialis cheap canadian pharmacy the solution.

Old Massachusetts Landfill Will be Home to New England's Largest Solar Array

canton-landfill
Canton, Massachusetts will be home to levitra costs New England's largest solar array when the town installs the renewable energy project atop an old sealed landfill.

The landfill was capped 25 years ago and has been out of use since, but now the viagra gel site will be home 24,000 solar panels capable of producing 5.6 MW of solar power.  The project could be completed as soon as 2012 and is visit web site soft gel levitra being built by Southern Sky Renewable Energy.  The array is expected to bring the town $70 million in revenue and purchase discount viagra energy savings over 25 years.

Landfills are great locations for solar installations because they're flat, free of trees and are removed from buildings and structures, so there are no shadows to worry about.

The Canton array will likely be one of many landfill arrays coming to Massachusetts as many towns are looking for new sources of revenue and the state has set a goal of installing 250 MW of solar power by 2017.  The state currently has 76 MW installed.

Lots of cialis 100 mg Hot Water from Small-Scale Parabolic Solar

parabolicsolar

Parabolic solar dishes generally come in two sizes, the very small "solar oven" and the large, industrial scale solar furnace. But now, a Canadian company is making parabolic solar dishes for small commercial and even residential use.

The Solar Beam Solar Concentrator produces up to 13kW of heat per hour according to the company. That's far more hot water than most households would need, but could be practical for a home with hot water radiators or in-floor radiant heating.

Solar Beam uses a 15 foot (4.5 meter) diameter parabolic dish. A block of aluminum 10 x 10 inches (25.4 x 25.4 cm) absorbs the heat and transfers it to a glycol fluid which circulates the heat to the equipment where it is needed. The company also claims a much faster payback for the Solar Beam as compared to cod online tramadol flat panel solar water heaters. "The SolarBeam is 262% more efficient that hot water panels and 98% more efficient than evacuated tube technology."

The Solar Beam uses a 2-axis controller to track the sun throughout the day, in order to increase efficiency of energy collection. Since just one dish has to be tracked, it is much easier to do this than it would be to have an array of flat panels tracking the sun. Since the buy levitra from china collector can be ground mounted, it can be possible to use it for solar hot water in places where orientation or other factors do not make rooftop collectors practical. The smaller size also makes it possible to use the dish in places where there is not the space available for a large rooftop array or where it might be otherwise undesirable.

Princeton Building Large Solar Collector Field

princeton-solar
Princeton University announced that they are building a large solar collector field, one of the single largest solar installations of any U.S. university.  The field will be made up of 16,500 PV panels, producing enough energy to levitra lowest price power 700 households.

The solar field will take up 27 acres of Princeton-owned land and should be installed by 2012.  Once the field is operating, it will cut the college's electricity costs by eight percent.  The builders of cheap viagra canadian the field, SunPower Corp., say it could produce 8 million kWh per year, covering 5.5 percent of the campus' annual electricity needs, but under ideal sunny conditions, the field could cover up to 20 percent of the campus' electricity needs for any given hour.

This project is cash on delivery tramadol sat delivery part of the university's bigger goal of reducing its emissions to 1990 levels by 2020, which is 95,000 metric tons annually.  The solar field is expected to account for six percent of that reduction.

First Solar Sail Spacecraft Circles the Earth

nanosail-d
NASA's NanoSail-D has become the first solar sail spacecraft to orbit the we recommend generic cialis canadian Earth.  At first, the tiny spacecraft got stuck when team members tried to release it from the FASTSAT satellite in late 2010, but a few days ago it spontaneously ejected from the satellite and real levitra online starting sailing its way around the planet.

The probe on the NanoSail-D is the size of a breadbox and the sail is ten square meters.  NASA plans to observe the spacecraft and study how it can be used to bring old satellites and space junk out of orbit.  As a solar sail circles circle the planet, it skims the http://www.breinweb.nl/online-levitra-prescriptions atmosphere and aerodynamic drag eventually brings it down out of orbit where it burns up in the atmosphere, which for the NanoSail-D should happen within 120 days.

While NASA plans to stay close to home, Japan's space program JAXA is using solar sails to generic cialis cheap venture deeper into space. Last year, JAXA deployed a solar sail spacecraft called IKAROS in interplanetary space where, using the pressure of sunlight, it sailed by Venus.  A follow-up mission to cruise by Jupiter is planned for later this decade.
