Point taken on EVs! My only experience is using them for robot builds and it may be the quality of the battery thats at issue. In comparison to fossil fuels lithium is obviously way better but I think long term I would prefer to use sodium

Think about how much easier it would be to extract sodium. If half the effort went into making those batteries better the lithium scramble could have a chance of ending. Zinc bromine is another good option which would be relatively ok in te

Lithium batteries seem to blow up a lot or a lot more than they should. People say that this doesn't matter for the best made batteries, which is fair in those cases, but judging safety relative to an ideal is not wise. Its also absolu

I think this comes down to the growth of scientific management and technocracy in research and that bureaucracy's attempt to fight over dwindling public funding for the sciences coupled with lack of private non-commercial sources of fu

I definitely would use version based cad programs with coding options but the pickings are pretty slim for industrial applications aside from the big players. Particularly programs that can be custom built to the users needs. Solidworks and

Tayto was the first/one of to infuse the flavour into the crisp (US:chip). Before that there were little salt packets that you sprinkled. The guy who invented the process was nicknamed "Spud" Murphy.

The author highlights a good consideration that its not just the filament (e.g. pla) but also the printing process (e.g. hotend materials and bowden tubes) that may effect the body safety / biocompatibility.

Nice thanks, checking this out and apart from some browser loading slowness this seems really cool. I'm stuck between booting up altium on my windows sbc and kicad on mac so this might be perfect. p.s. Crazyfrog! I remember hearing th

Looks good, I'm looking to brush up on Kicad or learn Altium to compare. Phil's Lab on youtube is a great resource for learning pcb design.

This research has been ongoing for a long time: Development of the sodium-ion battery took place side-by-side with that of the lithium-ion battery in the 1970s and early 1980s. However, by the 1990s, it had become clear that lithium-ion bat

This kind of research really needs to develop/use less stiff and/or non metallic conductive implants. For example organic conductive materials. The immune response to stiff metallic electrodes means that it will never last as a b

This is inspiring. The cost can be brought down through use of soft and/or lightweight materials. For example, the use of textile based actuators. Good examples in link below: https://biodesign.seas.harvard.edu/soft-exo

Lots of cool stuff in this field. They are "ultrasonic tweezers" and ultrasonic should be in the title (of og article) to give more information and lead people in the right direction. https://www.sciencedirect.com/
