I feel it's likely that a human will need to give the robot the weapons free s authorization but that may be overly optimistic.

I wonder what a venturi would yield for performance. Could help on slow days.
Water vapor is also a weak greenhouse gas. One problem begets another.
I wonder if this would be possible for the middle east to tow in. That would eliminate the possibility of the melt raising the sea levels and keep CO2 out of the air by displacing desalination.
I'd imagine you'd need to break it up into chunks as even a fleet of tugs couldn't tow something that massive easily. But it would be a fascinating endeavor.
Nitrogen is a weak lifting gas. If you inject it into a burrow it will just float out.
Is Kerosene cheap? Stockpiling enough kerosene to make it through a gas fluctuation should be trivial. In Japan my main spaceheating kerosene tank held 80 liters and I kept 100 liters in reserve on my deck.
a closet could easily store 200 liters in poly tanks. 1 liter could heat the house for two hours. So a typical heating day I would use 4 liters. Use an electric blanket at night. So my stockpile could last me about a month. Maybe less for you. How long is a gas cutoff?
For electricity you could stockpile diesel and enough to run a generator for weeks. you could use cogen by running hot water from the cooling system into a radiator in your house.
I'm unfamiliar with your housing situation but a lister clone diesel with generator is probably $1000 and could run your house and they last forever. can also be serviced by hand. probably same rate of fuel consumption 4 liters per day with enough heat to cut space heating requirements in half.

Answer: Yes but lithium only makes up 3 percent of the cost of a lithium ion battery so recycling is uneconomical vs virgin production. If demand ever exceeds supply then that will likely change and old batteries which were thrown out will likely be reclaimed. Currently as I gather it there is about 12 pounds or $250-$350 worth of metallic lithium in a 75kwh battery pack. So currently lithium prices are a minimal impact on pack pricing considering that's a $20000 pack.
Or clean it with fire. Put it in a red hot flame and it should clean right up.
Or you have each bullet programmed to track one of thirty different laser frequencies. And then have the gun read the frequency from the bullet and produce the correct frequency laser.
If the goal is to reduce global warming however, methane is a much more powerful warming gas. What I think would be a better use is transformation to calcium carbonate. This would produce cement.
They're not under common law to do anything if they're family owned small business which is what the summary specifies. I doubt google or facebook could try it.
Here would be how you calculate it..
10kwx2=20kw
1 gallon of gasoline is 33.4kwh (wikipedia)
@42% efficency, 20kw is consuming 47.6kwh/gasoline per hour
This gives 1.425 gallons per 52.6 miles per gallon, however if you assume the motors, charging system and resistance losses account for 10% efficency loss you get 47.3mpg highway at 75mph.
However, if we assume that you drive 60 instead of 75, alot of sites say you loose roughly 20-25% driving at 75. So at 60 if you gain 20% fuel economy it'd come out to ~56-7mpg, or within spitting distance of a prius.

I believe the key difference here is that the soyuz space capsule hasn't killed anyone in 43 years. Which is mildly less impressive than the japanese shinkansen's no passenger fatality record. But more impressive than the shuttle's recent track record.
First off, Japan is space starved and property prices around it's population centers is staggering. Also, 80% of the country is mountainous.
Second of all, the irradiation in space is higher, about 1.3kw per square meter vs 1kw at the equator.
If you count in the fact that the sun is shining 24 hours a day 365 days a year.. versus the estimated 6 hours a day of good sunshine down on earth, you end up with roughly 5x the light per square meter of collector per hour per day averaged.
There's also no dust to mire the panels in space, or atleast not dust as we know it on earth. And if concentrating solar is used, like in the mirror design, high efficency solar panels can be used, again resulting in a 1.5x-2x boost in efficency per square meter of collector.
Cost wise though it'd probably be cheaper to fill every house's roof with solar panels, before going the space based route first. Economics is likely to be much better, unless they find a way to launch massive unfurling mylar mirrors into space, get them to play nice, and do it cheaply.
This all being said, if there's any way you could use local asteroids to start fabricating SPS's in orbit, then the economics change entirely and it's not so easy to say how it will play out.
