The Morning After: EV-charging roads in Indiana

One problem with our electric vehicle future is the need for ubiquitous, easy-to-use charging points all over the world. After all, the only way to avoid range and lines-at-the-charger anxiety is to make sure you can get power whenever you need it. That’s what makes a project, started by Indiana’s Department of Transport, so exciting: It’s working on a road that can charge your EV as you drive.

Backed by the National Science Foundation, and in partnership with Purdue University, the team will test concrete embedded with magnetized particles. This magnetized cement, or Magment, will be produced by a German company (also called Magment). The idea will, if early tests prove successful, see Indiana’s DOT build a quarter-mile track of Magment to see if it can charge a heavy duty truck while it trundles along.

A number of countries, including the UK and Sweden, are currently testing road-based charging. If it works, we won’t need to reorder our lives to accommodate an EV. Better still, permanently available power may make it easier to build cars with smaller batteries, knowing you’re never more than a few inches from your next set of electrons.

Steam Deck can limit frame rates to give you longer battery life

The target is 30 frames per second for an extra hour or two of juice.


Steam Deck, Valve’s handheld console, brings PC gaming to your morning commute. The open question, of course, was how such a wee device would cope with the demanding, graphically intensive titles of the last few years. Valve’s Pierre-Loup Griffais explained that the console will ship with an option to limit the frame rate. This Frame Limiter, which has a lower limit of 30 frames per second, was tested on Portal 2, which lasted four hours without it, and six with. It seems like Valve is at least aware its handheld is more than a little ambitious and is making every effort to ensure it actually works. Continue Reading.

China plans to build the first 'clean' commercial nuclear reactor

Reactors using thorium and molten salt is the holy grail for clean energy visionaries.

China has unveiled its design for a “clean” nuclear reactor, which is at less risk of meltdown and doesn’t require water for cooling. This reactor, which uses thorium and molten salt, is a bit of a holy grail for our clean energy future, at least until something better comes along. Tests should begin later this year, and there’s hope of seeing the first working commercial reactor in the early 2030s. Developed by the US in the early ‘60s, thorium and molten salt reactors are comparable to current uranium reactors. Why was the technology mothballed? For a couple of reasons, most notably because, unlike uranium, the technology didn’t work for weapons. Continue Reading.

NASA's Ingenuity helicopter has flown a total of one mile on Mars

This is one air mile you can’t trade in for extra legroom.


Ingenuity, NASA’s Mars helicopter, has now covered a mile of distance flown while studying the surface of the Red Planet. On its latest jaunt, the 10th so far, it zoomed around taking pictures of the Raised Ridges region of the Jezero Crater. They will help mission commanders determine if the Perseverance rover can make it over the rough terrain. Continue Reading.

Tokyo Olympics opening ceremony included a light display with 1,800 drones

A globe made of drones was a very impressive sight.

The 2020 Summer Games, before all of the running and jumping and swimming started, was a feast for the more nerdily inclined. The opening ceremony featured a light show, with a fleet of 1,824 drones taking center stage. Initially forming the shape of the five rings, the craft then recombined to create a 3D globe in the air, while a rendition of Imagine, re-orchestrated by Hans Zimmer, rang throughout the stadium. And the geeky festivities didn’t stop there: The athletes walked out to orchestrated versions of classic video game songs. Continue Reading.

Paraffin Oil and Water Dot Matrix Display

In preparation for Makerfaire, [hwhardsoft] needed to throw together some demos. So they dug deep and produced this unique display.

The display uses two synchronized peristaltic pumps to push water and red paraffin through a tube that switches back over itself in a predictable fashion. As visible in the video after the break, the pumps go at it for a few minutes producing a seemingly random pattern. The pattern coalesces at the end into a short string of text. The text is unfortunately fairly hard to read, even on a contrasting background. Perhaps an application of UV dye could help?

Once the message has been displayed, the water and paraffin drop back into the holding tank as the next message is queued up. The oil and water separate just like expected and a pump at the level of each fluid feeds it back into the system.

We were deeply puzzled at what appeared to be an Arduino mounted on a DIN rail for use in industrial settings, but then discovered that this product is what [hwhardsoft] built the demo to sell. We can see some pretty cool variations on this technique for art displays.
