It’s surprising how easy it is these days to line up all the components necessary for a residential-scale photovoltaic array. Solar panels can be purchased on Amazon (among other places) and tracking systems are readily available, too. If you have the land or your roof isn’t right for your needs, Arizona-based Schletter makes a ground-mount kit for up to 2.5 kW of solar PV and it can be purchased for under $1,000.
It’s been a while since I’ve seen anything new in the world of small wind, but I recently noticed that Bornay turbines from Spain are now distributed in the United States. The company has several models, including two-blade models rated at 600 watts, 1500 watts, and 3000 watts, and a three-blade model rated at 6000 watts. The Bornay 1500, for example, is about a nine-foot turbine that weighs 90 pounds and cuts in at winds of six mph. The 1500-watt kit is sold for $20,000 by Electrex Industrial Services.
Luke Anderson started with a reasonable request for $4,000 on Kickstarter, and he reached funding in 24 hours. Now, with 14 days left, Anderson has $25,000 in support for Alva — The Lightbulb Lamp. It’s 8.5″ wide by 17.5″ tall and comes in brown, white, or black ceramic base options. The lamp is powered by a replaceable LED with a hand-shaped filament. Alva* looks like a classic early Edison bulb, but it’s a lot bigger and will retail after the Kickstarter campaign for $550.
WaterFurnace International, Inc., a manufacturer of geothermal and water-source heat pumps, just launched what the company is calling the “world’s most energy-efficient heat pump,” according to a press release. The 7 Series 700A11, pictured, is the first variable capacity unit available for homeowners and boasts a 41 energy efficiency ratio and 5.3 coefficient of performance. The 7 Series exceeds Energy Star requirements and qualifies for a 30% federal tax credit, said WaterFurnace. The heating and cooling system also comes with a laundry list of other design features: integration with automation and energy monitoring systems, online remote monitoring and control, quiet performance with a lower compressor speed, advanced hot water generation, and a port for service and diagnostics that doesn’t require opening the unit. 700A11 uses a soft-start variable capacity compressor, variable speed ECM blower, and variable speed loop pump to scale output as needed.
When Hulger launched a designer CFL called the Plumen, most of the design world went crazy for the product. So perhaps it will be with the new Nature LED bulb by JUSTLED. The bulb was on display at Dwell on Design, to the excitement of certain design blogs, and presents what could be the best way to go naked (or exposed) with a LED light bulb.
Since I last shared photos of the Dow POWERHOUSE Solar Shingle, this line of business has picked up. In October 2011, the Solar Shingle launched in Colorado, and Dow expanded the launch to Texas and California in April 2012. As part of the launch, this commercial — lazy roof — aired recently to show these markets how Dow is helping to reinvent the roof so that it not only provides shelter but power, too.
