  • A Plastic Motor Just Defied a Century of Engineering Assumptions

    Jump

  • 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.

  • As someone who works around a lot of white blue-collar workers, yes they really are the dumbest most pig headed idiots you will ever find. No amount of evidence, financial pain, or debate will change their stupid, shrivled, idiot minds.

  • What is a game you can’t understand why its so popular ?

    Jump

  • Death stranding was the most boring trudge of a game I've ever played. I have no idea why it's so popular.

  • Why do people claim when they buy lets say an M16 Fully Automatic Assault Rifle it is for hunting or self protection? Could you just bow and arrow during a hunt for more of a challenge?

    Jump

  • Almost no one owns an m16. That would be a NFA (National Firearms Act) weapon that requires a special tax stamp for and would also have to be made before 1986. No new fully automatic firearms have been allowed to be made except for LEO/military purposes since 1986. All the of what you're calling an "m16" is an AR-15 (Armalite Rifle 15) or some variant. They're all semi-automatic.

    The AR-15 is so popular because it is a very accurate, reliable rifle, and can be very affordable. It also helps that it's the civilian model of the m16 and m4 rifles the military has. I have one that I target shoot with and it's a very fun rifle to use. That's probably the biggest reason it's so popular.

    I do agree that we need much stricter gun control in this country but it needs to be based around logic and fact. The "assault rifle bans" of the 90s were completely useless and didn't van anything meaningfully dangerous. They banned things like collapsable stocks, threaded muzzles and other silly things that don't effect the operation of the gun. Hell, California currently bans rifles with pistol grips, so when you buy an at there it just has a different grip. The function of the rifle is still the same. Personally I think we need stricter licensing on who can own a firearm. You should have to prove you are competent, capable, and safe in your use of firearms before you're allowed to own one. That includes VERY thorough background searches and atleast 20-30 hours of instruction. The old tired adage of "guns don't kill people, people kill people" does have some truth to it. But if less people had the guns to begin with, they'd have a lot harder time hurting people.

  • Or you can just put an ethanol rated carb kit and fuel line in it and not have to worry about it.

  • Good news, you're not fucked. Your car has been running on roughly 10-15% ethanol its entire life. If you havnt had problems yet, you likely won't. Unless they go full stupid and put an absurd amount in of ethanol in, then it won't effect most cars on the road today.

  • 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.

  • What do you think is the modern day equivalent to asbestos in 1960?

    Jump

  • 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.

  • What do you think is the modern day equivalent to asbestos in 1960?

    Jump

  • Asbestos isn't used in brake pads anymore, we've gone to organo metallic mixtures. So mostly carbon with some iron, manganese, and nickel thrown in.
