I guess they should have gone to space instead. 

Titanic still adding to the death toll, 111 years later.

I think it’s a bit unfair to call this a giant pissing contest. Sure, maybe it is an example of billionaires trying to one up each other. But it’s certainly also possible that these people are passionate about this stuff and have the money to actually go and do it.

I hope they are found and rescued alive. I mean, you really have to be an a-hole to want otherwise.

Since they can’t open the sub from the inside, even if they surfaced there’s a time limit for the rescue. Since communication seems to be lost, I don’t know how feasible it is to find them before the deadline.

Ballast is ballast.... I don’t care if you strap on a ton of lead or a ton of steel, when it’s on the exterior of the vessel, it’s not gonna make a difference.

Carbon steel is the same strength in compression and tension.

What’s the big deal about the sub using Logitech?  The US Navy uses XBox 360 controllers on its submarines.   And the world’s first robotic IVF procedure used a PS5 controller.  

I’m not an expert in DSV design or construction, so I’m not going to go so far as to agree that this was amateurish or unsafe. But when you consider what a real DSV looks like - with it’s multiple redundancies, emergency separation systems, navigation systems, and the small matter of a design that allows the crew to…

Wouldn’t the purpose of the RTM be to transmit real time hull strength data to the pilot who could then determine whether to continue the dive, or abort based on the readings?

It seems what the Coast Guard is trying very diplomatically not to say is that unless this sub is found on the surface, there’s no hope of rescue.

Don't forget where the wheels went.

Oh my god, this would be the perfect size vehicle to pick up the kids from soccer practice or drive to the mall…. So far ahead of it’s time.

I mean, technically, we’ve had hybrids for a century! Diesel-electric locomotives use a massive diesel engine to provide power to traction motors. Chevy tried to emulate that with the Volt, though as I understand it, the Volt’s engine can couple to the wheels in some situations.

Battery chemistry. There’s a lot of nuance to mass producing things and the whole supply chain, plus the incredible amounts of oil money & infrastructure out there that a lot of people rely on. However, the advancements in battery chemistry are a really big deal when it comes to personal transportation. 

You were right. I was warned. I choose to read it anyway and now I regret my decision 

Well, it’s not like the make good manual transmissions nowadays anyway. When most reviewers say the new M2 is subjectively better with an auto, they’re doing something wrong. Sad day, but it won’t be missed in BMW’s case. Now had they been making great manual transmissions all this time, that would be a different…

Pretty much this, ZF has essentially become the defacto transmission in damn near every car out there.  There is little reason to bother dumping R&D money in designing a new tranny, unless you a bat shit crazy bald swede, so most just don’t.  That and sticks are inferior in every way to a DCT, with the exception of…

It makes sense - torque converters are lower maintenance and smoother than clutches. And planetary gearsets have better packaging overall per gear.

Yeah, no point in having a manual EV. The motors can do 200 mph with one gear. Why shift?
