Can BE-Wind’s New Windmill Provide More Wind Power?

BE-Wind* is taking what you think you know about small wind technology and turning it on its head. It has improved performance and made its windmills quieter by blocking the wind! How does the company do that? The Science of Wind Power Generation Current vertical wind generation systems are inherently inefficient because the wind that powers the unit also works against it, as equal amounts of force are applied to both sides of the generator’s blades (see diagram below). So,…

SDG&E Utility Warns It Will Hit Net Metering Caps By Mid-2016

Last week San Diego Gas & Electric warned distributed energy enthusiasts it expects to reach caps on net metering in the summer of 2016. According to pv-magazine, SDG&E’s numbers show that existing installations and pending applications take up 74% of available capacity in the program. This opens the door to what “net metering 2.0” might look like, pitting utilities and distributed energy advocates in a face-off. Current estimates show 30 MW of rooftop solar is being added each month under net…

New Rooftop Wind Turbine Technology

Wind power is a major source of renewable electric power in many places around the world. We usually associate wind power with tall wind turbines located in remote locations or far out to sea. In July, Denmark produced 140% of its domestic energy from just such turbines, according to The Guardian. Yes, that record was established over a rather windy 24-hour period, but it is remarkable all the same. Until now, small wind turbines that are sized for residential and…

Our 7 Favorite Examples of Innovative Airport Tech

Not every airport is equal. Even airplane passengers who will barely see a dozen airports in their lifetimes know that some airports are dramatically better than others. Yet, for pilots, attendants, maintenance professionals, and other aviation experts, it isn’t necessarily the availability of outlets that makes one airport superior to another — it’s the efficacy of the technology. Aviation tech continues to become cheaper and more efficient, but oftentimes airports get mired in their old, bungling ways. Here are a…
