NASA was developing plans for an 8 meter monolithic optical/UV space telescope concept[1]. NASA's concept videos from 17 years ago are still rattling around on YouTube[2]. All that died when the Ares program was cancelled and the

Reactors have been flown and made critical in flight, but never used to provide power for aircraft propulsion. The Soviets got the closest, but they abandoned it as well. Recently Putin has revived a nuclear powered cruise missile design.

I find it useful in small doses even at small scale. When you have only one of a thing processing stuff it's useful to isolate that behind queues so you can bounce it and lose nothing: "pause" the incoming queue (new message

That's pretty cool. Kudos DeepComputing, Framework, et al. Tenstorrent is supposed to be delivering a "high-end" RISC-V CPU soon/this year... Don't know what it will look like, but one can dream: It's Jim Kel

It's a self inflicted situation by dependees. Tools in widespread use, JupyterLab for instance, has users tossing dependencies onto the pile, offering next to no guidance on dependency version control, as if expecting them to have to

Among conventional 4-cycle ICE designs there are some recent generator and marine applications near 50%. F1 designed an amazing hybrid system that achieves 50%. Those are the best figures I've seen. The F1 hybrid design is pretty ama

That bit of snark is about the ESP32 brigade that plagues every project or story that involves any non-ESP32 MCU, including this one. Yesterday I watched a long live video by the engineer of a open source engine management system, and he t

Maybe Wired should write a story on how to flush toilets without a municipal water supply. If you can't think of at least 4 ways to move water without electricity, a toilet is probably pure magic.

The clamping force is distributed over an area: \sigma = F/A. Adding ring terminals increases the total clamped area, reducing the pressure seen at any point on the surface. Since increasing from 1 to 2 doubles A (assuming each has t
