Capacitors could be great for drag racing. You're only going a quarter mile, so energy density isn't important. If you actually want to drive your vehicle anywhere, they won't store anywhere near enough energy for their size and weight. That's why Tesla (and others) use lithium ion batteries exclusively. I shouldn't have to say this, but the people doing this are not stupid.

Vinyl is an archaic, cumbersome and inferior medium that can be considered pretty much obsolete, but people like it for nostalgia, album art/liner notes, coolness, and elitism :) That being said, for what it was, the sound quality on a well-made vinyl album with little/no wear and tear on it could be pretty good. It's just that, a really good-quality digital recording is indistinguishable from the original source material, and is also very convenient to work with--and it doesn't deteriorate no matter how many times you play it.

Does the ultra-efficient, long-range electric truck weight too much for the law to accept? Adjust the *LAW*, not the truck. If I were Elon, I'd seriously just build the best damn rig I could, and let the bureaucratic bookworms have as much of a hissy fit as they need to get themselves off.

They'll make more than one, I promise...

Ion engines have been around for a while. The thruster itself isn't the big deal, it's the power source that's the tricky part. They're a cool idea and certainly work, but require energy input to produce thrust like any other engine.

??? Not sure what brought that up. All rechargeable battery types are recyclable.

It's strange to me that the USA produces such small quantities of these necessary elements, since they're such a large and busy country. Why not get down to business, Murrica? Is the problem that it isn't cost effective to develop your own supplies of these resources? Even worse than that, is it a political problem?

I'm inclined to agree with you. I'm not sure why Tesla is doing this, other than for the sake of a marketing gimmick. Yeah, let's play some video games in the car. I hope this shit is completely disabled whenever the car is moving!

@skyeplaysgames6734 Hey, don't knock genocide until you try it! I'm in favour of the world ridding itself of all psychopaths, for example. Genocide ain't such a bad thing, just be reasonably selective about who you exterminate, and it could go a long way towards making the world a much better place for more evolved humans to live. I guess that's not very PC, but I'm talking about psychopaths, and fuck them :)

If you've ever built anything or worked with anything mechanical, you know Robertson screw heads kick ass and all the other designs completely utterly suck.

0:26 Low-mounted wings weren't used to "increase maneuverability". Mounting the wings low was done to allow the wing spars (strong, heavy structural beams that give the wings their strength and stiffness) to pass through the bottom of the fuselage, leaving room for the pilot and engine. The engine was huge, so the pilot's canopy was located rearward, and mounting the wing at the top of the fuselage was a no-go. Many aircraft are built this way, it leaves more room inside the fuselage for useful payload. It has nothing to do with maneuverability.

@Tacticaviator7 Yes! Actually, a certain problem with the Canadian-built Avro Arrow was the high-mounted wing, which required long, fragile and heavy landing gear. If they had mounted the wings low, it wouldn't have been a problem. If they had attached the landing gear to the fuselage instead of the wings, it would have used up valuable space inside the fuselage for fuel, engines, weapons etc.

It certainly will. If the Roadster 2 has about 1 megawatt of power (about 1,340 horsepower), that's only a 5C pulse discharge for the 200 kWh battery pack. Shouldn't be too big of a deal for good-quality conventional lithium ion cells. No super-duper-ultra-hyper-uber-mega-Armageddon-capacitor needed.

Hardly a "fatal flaw", just something the pilots had to be aware of, much the same way that retractable landing gear isn't a fatal flaw--you just have to remember to lower the gear before landing the plane. No big deal.

It's a type of question you ask when you're in tha Hood

1:57 A microphone always produces an analog signal. Same with guitar/bass pickups.

@stevenx3m There's always going to be a bit of delay when you convert to digital though. Just how it works. Trick is to reduce it so it isn't noticed, probably not too hard to do since USB is so fast now. Whoa, it's been 2 years :)

4:28 You had a great explanation going, until this point, where you really buggered everything up :) The conversion of stylus/"needle" movement into an electrical (audio) signal doesn't happen at the back end of the tonearm, it happens in the pickup (cartridge). For converting the needle/stylus movement into a signal, either a piezo crystal is used (cheap to make and needs no preamp), or an electromagnetic pickup with permanent magnet and coil (still fairly cheap to make and expensive to buy, therefore better!) Anyway, entertaining vid :)
