Efficiency and infrastructure are THE ONLY THINGS THAT MATTER.
No, cost and convenience are. Both BEVs and FCVs are competing against internal combustion engines - whose inefficiencies are epic. But they're cheap and convenient.
You're absolutely right. Fuel cells are just an alternative (or more likely an augmentation) to batteries.
Batteries are efficient in terms of storing electricity, but are very heavy to lug around even when almost 'empty'. They also take a relatively long time to take on a full charge.
Fuel cells solve both of these problems, but are currently more expensive to fill. Cost to manufacture is in flux for both.
Don't be fooled by overall efficiency arguments. It's only about cost and convenience. Both of these technologies are just beginning to challenge internal combustion engines - which are notoriously inefficient, but cheap and convenient to run.
I see this being mentioned over and over again - Hydrogen is nearly impossible to contain. Yet Germany managed to do it in f'ing dirigibles in the 1930's. Yes, it ended with the Hindenburg disaster, but they had made several transatlantic flights, containing the hydrogen with 1930's technology balloons, before one ruptured for reasons still argued about. But you know what? Most of the people aboard the Hindenburg survived.
Today, hydrogen is shipped all over the world. The hydrogen tanks in the Toyota, Honda, and Hyundai FCVs are not science fiction. They're in production.
Tesla promised this. A 90 second swap. I believe it was actually demonstrated on a stage. But AFAIK, there is only one Tesla battery swap location, it operates on an appointment-only basis and charges $50/swap. Plus, you're potentially swapping your brand new battery for someone else's 5 year old battery. I think you're supposed to come back for your own battery at some point.
The idea of shipping 1,000lb batteries around the network is pretty silly.
Teslas can get 170 miles worth of charge in 30 minutes at their Superchargers..
FCVs are going twice that far and refuel in 4 minutes. The Teslas may be able to partially charge in 30 minutes, but what happens when all the charging stations are in use?
Imagine if the Hindenburg was filled with gasoline fumes. Everyone would've blown to tiny bits. In fact, most of the people aboard the Hindenburg survived.
Cloning an extinct species may be an important technology. We are currently creating a mass extinction event, and may need/want to bring back some species we killed off. It might even be profitable or lifesaving, like producing a cure for an infection or Star Trek IV.
I don't think there will ever be a cure for Star Trek IV.
Why is a healthcare insurance provider collecting income information on the people they insure?
I've worked in employee benefits for over 25 years, and the usual reason is that they are administering more than your health insurance. Often you also have short-term and/or long-term disability insurance, or life insurance. The benefits of these are based on some percentage of your salary. Your short term disability benefit may be 60% of your salary, or your life insurance benefit may be 2 X salary.
In all my time working for insurers like Anthem I have never been asked to pull salary data for anything not related to the above.

No, really, what does this mean? Why would I buy a Windows machine and run Linux on it?
I, for one, would like to live in such a place.
No, that's not direct control. They have to ask for it. That's far from it. Apple and MS have in certain cases stymied the process up a bit.
I'm not worried about the NSA. I'm more worried about Barney Fife.
But I agree that it may be the last, worst, option.
But, if my ISP was the government?
Besides, I'm more worried about some dillweed Sherriff's deputy's misinterpretations than an NSA super spy.
I'll take off my tinfoil hat if you take off your AC hat,
...But I'm really starting to think internet-as-a-municipal-utility is the answer here.
Well, except for the whole direct government control of my data thing.

Why not simply have replaceable batteries that you swap?
Ask Mr. Musk about this option. In reality, it's not nearly as good as he hyped.

Conversion of electricity to hydrogen is only about 60% efficient, so you lose 40% right off the top.
But what is the efficiency cost of carrying around 1,000lbs worth of batteries at the back end?
but what happens when all the charging stations are in use?
Has this ever happened?
Yes, it has. http://www.valuewalk.com/2016/...
Nothing is being burned. The hydrogen combines with oxygen from the air to produce electricity and water.

You're going to be dragging around a 1000 lb. tank to get any useful range out of a hydrogen car if you want it to be remotely survivable in a crash.
Check the curb weight of a Tesla Model S and the Honda Clarity FCV. Tesla is 1000lbs heavier.
Toyota shot their tank with a variety of weapons. It took an armor piercing round to get it to fail. And then the hydrogen simply leaked out.
Plus, Teslas (for instance) are always dragging around an extra 1000lbs.
