Leakage is widely exaggerated. From what I read it's something like 0.1% loss from leakage.

1) You can blend hydrogen with natural gas. To go 100% H2, you may need new pipes, but this isn't an insurmountable problem. 2) These sensors aren't that big. It'll probably be like fire alarms but for hydrogen if we go that

I'd imagine it should change in the future. We're looking at something like a 10,000x increase in production so current models won't hold in the future.

Agreed. His ability is to generate hype for insecure men. Nothing else he’s done suggest any real genius. And his tweeting habits show him as surprisingly ignorant much of the time.

It's unlikely we'll ever build enough battery factories to catch up with hydrogen based energy storage. The other guy mentioned total global battery production capacity is about 300 GWh of storage. 300 GWh can be matched by a sin

1) Main strategy to avoid this is to just coat pipelines with plastic or make them out of plastic. Not all metals are equally susceptible to this process, and newer alloys are being developed that can strongly resist this phenomenon. While

True, but if you can make hydrogen at $1.40/kg, distributing it won’t cost that much more.

Your source is wildly out of date, and is almost completely wrong with regards to the current state of fuel cell technology. To give you idea of what he's wrong about, let's jump to part 4 where he says this: > In reality, >

It also ignores the way a car is being used. Sports cars are consistently more dangerous than say, minivans. This is true even if the minivan is poorly rated and the sports car is top-of-class in its safety rating.

Yes, many value stocks are near the price floor, and have almost no room left to drop further. Of course, some of these companies are that cheap because they are basically the walking dead of companies (e.g. Gamestop). But for the companies

Subway is just the lowest tier of sandwich shop I can think of lately. Could easily see them going the way of Quiznos and forced to restructure at some point in the future.

This is about the worst kind of end justifying the means mentality. This type of thinking should be avoided as much as possible.

Most of the structural and integration tests are already complete though. We're far into the "beta testing" phase as it were. Also, the BFR isn't anywhere near the state that the SLS is in right now.

That's not quite correct. SLS is still slated to launch June of next year. It may get delayed to 2021 if problems are found. Also, Orion already flown in 2014, and will undergo an abort test in April.

They're nearly finished actually. The core stage is in final assembly. We'll probably see a launch in 2020 or 2021.
