While the Netherlands is the country most known for its windmills, they were originally invented by the Persians. More surprisingly, some of them are still turning after 1,000 years. The ancient world holds many wonders of technology, and some are only now coming back to the surface like the Antikythera Mechanism. Milling grain with wind […]
Credit: Space Lab We have seen a recent surge of interest in whether it’s possible to grow potatoes and other plants in Martian soil, but what is the likelihood that a future (manned) lunar base could do something similar? To that end [Space Lab] is developing the LEAF project that will be part of NASA’s […]
The proposed AAPowerLink transmission line between Darwin (Australia) and Singapore. (Credit: Sun Cable) Recently Singapore’s Energy Market Authority (EMA) granted Sun Cable conditional approval for its transmission line with Australia. Singapore has been faced for years now with the dilemma that its population’s energy needs keep increasing year-over-year, while it has very little space to […]
It’s easy to use electricity — solar-generated or otherwise — to desalinate water. However, traditional systems require a steady source of power. Since solar panels don’t always produce electricity, these methods require some way to store or acquire power when the solar cells are in the dark or shaded. But MIT engineers have a fresh […]
In the past, building construction methods generally didn’t worry much about air quality. There were enough gaps around windows, doors, siding, and flooring that a house could naturally “breathe” and do a decent enough job of making sure the occupants didn’t suffocate. Modern buildings, on the other hand, are extremely concerned with efficiency and go […]
Recently, the EPA and COBB Tuning have settled after the latter was sued for providing emissions control defeating equipment. As per the EPA’s settlement details document, COBB Tuning have since 2015 provided customers with the means to disable certain emission controls in cars, in addition to selling aftermarket exhaust pipes with insufficient catalytic systems. As […]
To the extent that one has strong feelings about insects, they tend toward the extremes of a spectrum that runs from a complete fascination with their diversity and the specializations they’ve evolved to exploit unique and ultra-narrow ecological niches, and “Eww, ick! Kill it!” It’s pretty clear that [Dr. Andy Quitmeyer] and his team tend […]
Trees and forests are an incredibly important natural resource not only for lumber and agricultural products, but also maintain a huge amount of biodiversity in the various types of forests across the globe, stabilize their local environments, and can be protective against climate change as a way to sequester atmospheric carbon. But the one thing […]
Cutting grass with lasers works great in a test setup. (Credit: Allen Pan, YouTube) Wouldn’t it be cool if you could cut the grass with lasers? Everyone knows that lasers are basically magic, and if you strap a diode laser or two to a lawn mower, it should slice through those pesky blades of grass […]
Additive manufacturing (AM) has been getting a lot of attention over the years, with its use in construction a recurring theme. Generally this brings to mind massive 3D printers that are carted to construction sites and assemble entire homes on the spot. That’s the perspective with which a recent ZDNet article by [Rajiv Rao] opens, […]
