Net-Positive Earth Moving Equipment?

Massive earth moving equipment ranks among some of the heaviest and most costly machinery in the world, outside of experimental particle physics, of course... Not surprisingly, the mostly diesel-powered mammoth vehicles typically employed for major infrastructure projects require a great deal of that diesel fuel to get the job done. Considering that in many such … Continue reading Net-Positive Earth Moving Equipment?

California: It ain’t easy being a green builder (but there are some real opportunities)

San Diego's Building Industry Association played host to an outstanding and dynamic presentation earlier this morning on the topic of energy and the 2016 California building codes that went into effect at the beginning of this year. The panelists included a great mix of building professionals and thought leaders that don't merely speculate on the … Continue reading California: It ain’t easy being a green builder (but there are some real opportunities)

Should buildings keep weather out, or let it in?

Kevin Nute, writing for the Washington Post: A building’s primary purpose may be to keep the weather out, but most of them do such an effective job of this that they also inadvertently deprive us of contact with two key requirements for our well-being and effectiveness: nature and change. In the 1950s, Donald Hebb’s “arousal … Continue reading Should buildings keep weather out, or let it in?

Salt and antifreeze may be key to longer term solar energy storage at massive scale

Bloomberg's Mark Bergen reports: Alphabet Inc.'s secretive X skunk works has another idea that could save the world. This one, code named Malta, involves vats of salt and antifreeze. The research lab, which hatched Google's driverless car almost a decade ago, is developing a system for storing renewable energy that would otherwise be wasted. It can be located … Continue reading Salt and antifreeze may be key to longer term solar energy storage at massive scale

Without constant monitoring, solar PV efficiency remains limited

Solar panels leveraging photovoltaic (PV) technology to convert sunlight into electricity are notoriously inefficient. According to research by the International Energy Agency, one way to improve PV efficiency is through the implementation of Statistical Performance Monitoring combined with some advanced machine-learning. In their report, the researchers identified 4 different methodologies for improving solar panel efficiency, … Continue reading Without constant monitoring, solar PV efficiency remains limited
