Now that's a vicious circle, if I've ever seen one. You don't have the bandwidth, so you don't send more rovers, and then you won't upgrade bandwidth because you've only sent one.
Because they decided to make it a 2.5 billion one instead of a 400 million one.
Most of the cost is not building the rover, it's getting it to Mars, landing it
The cost of the landing is a part of the cost of the building the rover. The landing equipment is a part of it. As far as getting to Mars is concerned, these days, you can send ten MER class rovers to Mars in a single launch on a Falcon Heavy for, say, $150 million or so.
and supporting it while it operates there
They kind of screwed the pooch when it comes to satellites at Mars. Once they fix that problem, things will get much easier for multiple rovers.
>suggests Lua instead of JavaScript for performance
That's quite possibly the only language that's even *slower* than JavaScript.
Funny that you single out the one language that actually has an implementation matching or exceeding the performance of the best JS implementations, and completely ignore the languages for which your claim actually holds, such as Python, Ruby, Perl, PHP, Tcl etc.
Do you have any idea how many amps it take to charge an EV?! The gauge and amount of copper or alluminum would be astounding in the infrastructure needed to allow everyone to put a load on their EVs after rush-hour coming home.
Charging in places outside of people's homes during the day from excess solar power sounds like a much more reasonable proposition than loading the grid in the late afternoon. In any case, your concerns about the metals are moot since the grid is not fully loaded most of the time, so just intelligently taking advantage of that goes a long way towards realizing proper charging infrastructure.
And we're not even addressing the typical brown-outs that occur in the summer time from everyone turning on their AC.
It also eliminates this nitpick of yours, as does AC with thermal storage powered from the same source.
There's no nice way of putting it, so I'll say it - you're a fucking moron if you actually think EV is the future. NO FUCKING WAY!
Personal automotive EV transportation will never go mainstream.
There's a lot of "X will never happen" quotes that became famous for the wrong(ness) reason, but it really takes a special person to make such a comment just as that X in question is slowly happening.
As I see this, the LEO data route has to go 1200km twice to get next door, so you have to gain 2400km's worth of latency somehow over the ground based system.
First, why 2400 km? There doesn't seem to be a need to jump twice through the same satellite. Second, the Pythagoras theorem significantly diminishes the difference for medium distances.
Or do we go back to CFCs, knowing that those actually cool the earth (which is what we want)
...are you insane? CFCs are among some of the most potent greenhouse gases. If anything, the Montreal Protocol is credited with contributing to slowing the warming trend in the 1990s and throwing off some of the predictions of late 1980s.

They only have the budget for one rover

The school will now probably start charging higher tuition fees.

You must be a really powerful telepath to read his mind like that.
I have no idea. Likewise, though, I have no idea what it has to do with those presentations.
I'm pretty sure he wants to take credit for being a part of pushing it further still.
Who the hell knows the NAMES of the machines?
Uh...presumably anyone who bothered to watch one of the company's presentations?
You have to start with existing equipment before you find out what's wrong with it. Isn't that how it usually works?
Nuff said.
The law of bug fixing strikes again?

We'll see in twenty years who was the moron here.
It takes 40 amps @ 240 volts to charge a Tesla Model S overnight from dead empty.
...but most people don't drive 100000 miles per year. So that's more of a fringe case.
I wonder...if you're a programmer, and X and Y are integers, do you pronounce a relational expression of "XY" as "X is fewer than Y"?

Like OTRAG's problems had anything to do with market demand...

What optical material has a refraction index of 1.003? According to this table, the closest one is liquid helium. Surely that is not the case.
I wonder if you actually bothered to read everything before that sentence... It doesn't seem like that is the case.
Problem is, fiber on the ground is faster as the distance is shorter.
The ground distance must be shorter by at least 32% because the speed of light in fiber is 32% lower than the speed of light in free air.
Domain blocking may not work forever.
(Cue an APK rant on how that is not true and how domain blocking is the superior solution)
1) Where do you think the carbon dioxide is sourced from?
2) What do you think would have happened to it if it wasn't put into drinks?
So even if CO2 caused warming, for which there's no evidence, it wouldn't be bad.
Clearly you've been inspired by the denialist staircase.

Here's an illustrated guide.
