Pole Mount PV We’ve had a pretty good summer for solar photovoltaic (PV) installations in the Upper Valley of NH/VT. A typical PV system consists of a number of solar panels and an Inverter to change the DC (direct current) from the panels to AC (alternating current) which is used in our homes. Often the [...] I have been interested in weather-related data for a while, and once I went into the renewable energy business, it has become even more intriguing to me. I like to know how much sun, rain, wind, and humidity we are experiencing. I want to know about the inside temperature, the outside temperature and the highs [...]
Shower Time There is a lot of buzz these days about On-Demand hot water systems. “On-Demand” means the water is heated as it is needed. Most people have a hot water tank, where the water is heated and kept hot in a tank until it is needed. Generally the tank has been sized to provide [...] Since I opened my store one of the products I have been thinking about is an electric bicycle. I have been an avid cyclist for about 6 or 7 years now. My husband and I try to get in a one long bike trip each summer. (We just completed New London, NH to Boston, MA [...]
Wind Turbine Today, I was in Portland, Maine in a training class for Southwest wind turbines – installation and sales. It was fun and interesting and gave me some good resources and information to help people who have enough wind to generate electricity. We completed the construction of a 45′ tower, wired and attached [...]
Alternative mowers I have a Honda gas-powered lawn mower. I got it as a gift a few years back and it has been wonderfully reliable. Starts on the first or second pull every time. But it burns gasoline and I would really like a quieter, more energy efficient lawn mower. Electric mowers have been available [...] Using the sun to heat your hot water in the summer is probably the most sensible (and cost effective) place to trade off fossil fuel use for solar energy. It makes sense — the sun is out, it is bright and hot, why would you want to use oil or gas to heat water? I [...] Kent here with a guest posting. Hologram from a credit card I was at the MIT Media Lab yesterday. If you don’t know it, the Media Lab has for a couple of decades now been the place you go if you want to see into the future. For example, I saw a demonstration of a [...]
Pond fountain I’ve been investigating solar power water pumps for a customer who wants to add a fountain to his small pond. The fountain will be both decorative and provide aeration, but it doesn’t have to be on all the time. He wants the fountain to be self-sustaining using energy from the sun rather than [...] PowerCost Monitor I helped my father install this PowerCost Monitor from Blue Line Innovations. He has spent the last few weeks walking around the house with the monitor whenever it reads above 3 or 4 kWatts to track down the culprit. What just turned on? Why did it turn on? Should it be shut off? [...] |
