We can debate the details, but we’re still talking about a system that requires ground support equipment that would be far too heavy to fly if it had to be on the vehicle. You’re right that the Falcon 9 has the shortest launch window after tanking, but all liquid engine rockets tank within hours before launch.

I have no idea what you’re talking about, but you used the word blockchain too so I’m pretty sure a bunch of hedge funds are sending you money now too.

If your concern is truly the validity of the study, you should be A LOT more concerned with the fact that they surveyed twelve people that work together and called it a representative sample. But that’s not what you’re complaining about. You should also be A LOT more concerned that they didn’t even try to score the…

The problem is that, while its energy per unit weight is rather high, its energy per unit volume is lower than regular jet fuel unless you super cool it and pressurize it thousands of psi. That means you’re carrying high pressure/low temperature fuel tanks with either bellows or gas blow-down systems to keep the fuel …

That was a “not understanding static electricity” problem rather than a “not understanding hydrogen” problem.

I’m pretty sure your screen name just quadrupled in value for using the word blockchain. These new investing algorithms are pretty sweet.

No matter how much you fast track these new capsules, you’re still not going to be ready by the December/January time frame... Both the Boeing Starliner and the Dragon just delayed their first unmanned launches to 2019 for technical reasons so it’s not like they’re just sitting around waiting for paperwork.

Regardless of how much rigor they put into the blind taste test, the results are still going to be 100% subjective. Why invest in rigor if your test is meaningless no matter what you do?

Oh so you actually DO want to argue whose shit smells least awful. My point is simply that ANY feature not working on the first try is STILL a feature not working on the first try whether or not YOU care about it. Using other parallel examples was to demonstrate that bad ergonomic design and functional repeatability…

“Feature doesn’t work on first try” is not nothing. If your starter motor always worked on the second try, you’d probably be a bit more concerned than one that worked right every time on the first try. And in both cases, the cause traces back to bad design and bad quality control.

It may not seem important, but switch placement IS part of design and bad ergonomic design is not something you can really ignore is it? I mean, take it to the extreme. If they didn’t put a driver’s side door on it and you had to climb across the passenger seat to get in and out of the car, should it be ranked higher…

Because there’s a difference between air traffic control having to manage the twelve people operating ultralights in a given weekend and them having to manage the quarter million people commuting to work every single day... Is this really that hard?

A few things: Ultralights and paragliders cannot operate in a Class A, B, C, or D airspace without authorization from air traffic control. That basically means you can’t fly within 5 miles of an airport without authorization from ATC. They cannot operate in Class A airspace at all. They cannot operate in ANY air space…

They make t-shirts in all different sizes. Someone should tell him.

But you need more air traffic control... Or are we going to make flying vehicles more prevalent and decide that somehow negates any control over when/where they take-off/land? That’s like saying we’re going to put more cars on the road and reduce the number of traffic cops. Not gonna happen.

Notice I carefully used the term “flying vehicle.” Flying cars are little more than trumped-up private aircraft and the infrastructure required to operate those is extensive. If you think we’re going to transition to a system dominated by personal aircraft without a HUGE increase in the capability of air traffic…

Yeah because the infrastructure for flying vehicles now is just so cheap it’s practically free. /s

That GIF totally isn’t fair. The goal post should only be moving in one direction.

I mean, I’d assume that a company whose bread and butter is to assess profitability of a product to determine investment risk understands basics like economies of scale and technology shift. I’d be pretty shocked if they didn’t incorporate the former into their predictions, but the latter is just speculation and…

Can’t imagine what was going through the ump’s mind when coach went to grab a bat...
