If you have a lawn, you have several options to keep it neat this Spring, but the human-powered reel mower is probably one of more environmentally friendly ways to go about it. These things have anywhere from 4-7 blades, 14-20-inch widths, and varying weights, depending on the build of the chosen model. But what’s the best reel mower for your yard?

A company called Solyndra pioneered the solar tube but this new invention by UK-based Naked Energy may just take cylindrical solar to a whole new level. Called Virtu, the product includes an integrated photovoltaic cell in a vacuum tube to generate both electricity and warm water at the same time. The setup keeps the PV cool to optimize energy production and maximizes space with a combined PVT solution.
This is a net-zero energy showhouse in the Belgravia neighborhood of Edmonton. The home, built by Effect Home Builders, has been open on Sundays and displays the solar-powered approach to reducing the use of fossil fuels. A massive rooftop solar array feeds energy into the grid and produces as much energy as will be needed on an annual basis. In addition, the home has several other green aspects.

(ATR) on the roof of a row house in Federal Hill in Baltimore. The install consists of two panels, 235-watts each, on a sun tracking mount with a GPS-controlled drive unit that follows the sun to yield about 30% more than fixed panels.
