  • All these comments feel very nitpicky. Its a one of a kind, experimental motor. Built to test the properties of a new and a not well understood phenomenon. The fact that the motor moves at all is pretty amazing. We don’t know what the technology could grow into in the future, we don’t know what the applications could be. Simply because we don’t actually know what all this sort of device is capable of with further study and refinement. The tungsten filament lightbuld generated far more heat than light for over a hundred years before we managed to come up with the led, which in its infancy also barely produced light.


  • Politically related I work with a 23 yo self proclaimed “christian nationalist, ultra capitalist” who believes every single rightwing conspiracy and and talking point. He also constantly complains about how he’s not paid enough but also that the centi-millionaire inherited owner of the company works hard enough to earn all his money despite playing golf 4 day a week.

    In terms of good old fashioned stupid, I once saw an operator disable the guardingnon a machine, proceed to lose a finger to said machine. Then after being given a second chance less than a week back on the job decided it was a good idea to disable the same guarding again. Luckily he got fired before he had a chance to lose any more digits.










  • The main problem with ethanol in rubber fuel lines is that ethanol causes hardening and flaking of the rubber. Long before it ever gets bad enough to leak the little flakes of hardened rubber detatch from the inside of the line and travel down to fuel pumps, injectors, and carburators. Where they clog up all the small metered orifices that regulate the amount of fuel the engine is getting. This can lead to the car just not running or running poorly, to the internal components of the engine breaking or seizing, thus trashing the whole engine.


  • I’m a car girl, its mkind of my thing. Octane ratings aretgere to protect your engine, its a rating of how readily the gasoline ignites in the engine. The larger the number the harder to self ignite. Most cars use 85, the only time the higher octane 93 is needed is for cars with turbo or supercharging, or cars with higher compression ratios.

    Just put whatever its rated for in it, going with a higher octane than what your car is rated for doesn’t hurt a thing, but it also won’t make your engine run better or anything.

    As far as ethanol goes, modern cars ate fine with 10-20% ethanol in their gas. It will get worse mileage the higher the percentage of ethanol as it is not as energy dense as gasoline. The E85 stuff has a higher percentage of ethanol (85%) than is allowed in conventional gas and was introduced to try and lower gas prices (it’s actually completely ineffective and ethanol for fuel is more energy intensive than just giving us straight gasoline but they have to prop up the corn industry somehow). Regular cars can’t use E85 unless they are rated for it as the engine has to add more fuel to keep a close to stoichiometric ratio of fuel to air.

    TLDR: Use whatever octane your car asks for, if you put a higher octane in it doesn’t hurt, but it also doesn’t add any benefit.

    When it comes to ethanol regular cars can tolerate up to roughly 20% with only a reduction in fuel mileage as a result. E85 is only for cars rated to use it as they need a sensor to detect ethanol percentage and adjust fuel to air ratios accordingly.




  • So you swapped out a few pairs of NOS parts on a couple classics. I worked as an engineer for akebono, one of the biggest brake manufacturers in the world. Almost every European and American manufacturer ditched asbestos around 1990. Some imported “value” pads may contain asbestos, and some classic cars are still gonna have asbestos pads. But the vast majority of cars on the road do not.
