No worries. Still interesting!

Yeah, I think you’re right.

Ok. Have a nice day.

I have no idea what you are trying to say. Batteries have an environmental impact, but so does fracking for natural gas. You have the impact up front making a battery, but charging it with renewables does not have continued environmental impact. But if you use gas, you’re going to have to use an awful lot of it over that time period to offset the clean power you’re able to use when you have a battery. And that gas has a very high environmental impact, continually, over that entire time period.

I didn’t say batteries have NO impact, but they have less impact than continually mining and burning fossil fuels.

You make the batteries once, and the pollution due to production is spread over the 10-15 year lifetime of the battery. During that time gigawatt hours of clean power sloshes in and out of them. This in contrast to having to produce enough gas to make all of those gigawatt hours once, then throw the gas away as co2 and get more, along with the attendant pollution.

34% is 155% of 22%, so an even bigger increase!

The NSA has two jobs.

The first is to break into any computer or communications stream that they feel the need to for “national security needs”. A lot of leeway for bad behavior there, and yes, they’ve done, and almost certainly continue to do, bad things. Note that in theory that is only allowed for foreign targets, but they always seem to find ways around that.

The second, and less well known, job is to ensure that nobody but them can do that to US computers and communications streams. So if they say something will make your computer more secure, it’s probably true, with the important addition of “except from them”.

I won’t pretend I like any of this, but most people are much more likely to be targeted by scammers, bitcoin miners, and ransomware than they are by the NSA itself, so in that sense, following the NSA’s recommendation here is probably better than not.

If you can’t monopolize, the next best thing is to make sure nobody else can.

Maybe it should be. At least part of the package that’s signed.

OP said “no hardware vendor”, not “ no networked hardware vendor”.

“Why does this microwave oven cost $1500?”

“Two reasons. The first is that it has to have a full network stack to allow it to download software from competing appliance vendors. The second is the cost that the manufacturer had to bear to develop software for every single other microwave sold. There are some pretty weird architectures out there, and they had to hire a whole bunch of programmers.”

People keep complaining that solar and wind give us “too much electricity at the wrong time”, causing power prices to go negative (as if this is a problem). Having a beneficial process like co2 removal that you can do at any time of day (the co2 isn’t going anywhere) that would soak up all that energy seems like a win win.
