Ground-source heat pump systems are one of the most efficient ways to do climate control, but digging the wells can be prohibitively expensive for the individual citizen. What if you could do it at a larger scale? Starting with a pilot to serve 37 commercial and residential buildings in Framingham, MA, Eversource is using its […]
Vehicle-to-grid (V2G) has been hailed as one of the greatest advantages of electrifying transportation, but has so far remained mostly in the lab. Hoping to move things forward, the National Electrical Manufacturers Association (NEMA) has released the Electric Vehicle Supply Equipment (EVSE) Power Export Permitting Standard. The new standards will allow vehicle manufacturers and charger […]
Last October we showed you a video from [LiamTronix], in which he applied an electric conversion to a 1960s Massey-Ferguson 65 which had seen better days. It certainly seemed ready for light work around the farm, but it’s only now that we get his video showing the machine at work. This thing really can farm! […]
As the electric vehicle takeover slowly lumbers along, marginally increasing efficiencies for certain applications while entrenching car-centric urban design even further, there are some knock-on effects that are benefiting people and infrastructure beyond simple transportation. Vehicle-to-grid technology has applications for providing energy from the car back to the grid for things like power outages or […]
Siphons are one of those physics phenomena that, like gyroscopes, non-Newtonian fluids, and electricity, seem almost magical. Thanks to atmospheric pressure, simply filling a tube with liquid and placing the end of the tube below the liquid level of a container allows it to flow against gravity, over a barrier, and down into another container […]
For economic reasons, not every lake with a dam can support a hydroelectric power plant. Some rivers or creeks are dammed for flood control or simply for recreation, and don’t have the flow rate or aren’t deep enough to make the investment of a grid-scale generation facility worthwhile. But for those of us with a […]
We love electronic conference badges here at Hackaday, but it’s undeniable that many of them end up gathering dust after the event. Most of them are usable as development boards though, so it’s nice to see them appear in projects from time to time. [Benjamin Blundell] has a good one, he’s using an EMF Camp […]
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 […]
