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.
