Not really. You can buy a heavy-duty drone for agricultural spaying for less than $10k. This is somewhat expensive for an individual but not for any criminal or terrorist organization. Bonus points: these drones can be legally and untraceably imported from another country.
And this single drone can shut down an airport for hours resulting in tens of millions of dollars (pounds) lost in delayed and cancelled flights.
You most certainly can buy SmartThings for Germany: https://www.samsung.com/de/sma... and I'm pretty sure that Vera also has a hub for the European market. Not sure about Wink.
Uhm... Don't get IKEA hubs. Get something like Samsung SmartThings. I have lighting switches from 3 different manufacturers and they interoperate just fine.
ZWave and ZigBee devices along with a hub are typically considered to be IoT. And the hub can be fully offline-capable: Vera, HomeAssistant and OpenHab work perfectly fine offline (obviously without Alexa or Internet-device integration).
IoT devices themselves are fine. ZWave or ZigBee light switches don’t depend on whims of a manufacturer. You don’t need to replace them, just replace the hub.
I'm afraid, though, that the actual breeder setups you refer to are not _efficient_. I'm looking right now at the "breeder blanket" designs, and one of them look efficient enough to approach even 50% generation of tritium compared to that expended in the fusion reactor.
A mix of Li7 and Li6 can produce two tritium atoms from one neutron, Li7 reacts with a fast neutron first releasing tritium and a slow neutron. This slow neutron can't react with Li7 anymore but can produce another tritium atom from Li6. So in the best case the overall reaction can produce twice as much tritium as put in.
The engineering required for this is going to be decidedly non-trivial and it's one of the ITER's research targets. So basically nobody knows right now if it's going to work.
Please, stop spreading misinformation. Li-n reaction is exothermic, it RELEASES additional energy. There's also an additional side reaction that produces tritium and another neutron (this one is mildly endothermic but doesn't affect overall energy balance significantly), so it's possible to actually produce more tritium than is consumed.
The engineering challenge is going to be interesting but ultimately it seems to be solvable.
Aneutronic fusion is infeasible in classical tokamaks or stellerators, though perhaps He3 fusion will work. It really needs alternative designs to work, like Tri-Alpha energy or Focus Fusion. With TAE it's going to become clear within a couple of years if their approach is going to work and they have solid theoretical basis why it should.
ITER Is a distraction from fusion efforts that may one day be practical, which may be why it is the focus of funding. Contrary to your assertion, Bussard's Polywell has been making steady progress with a pittance of funding, and is still more likely to be commercially successful. So are a number of other projects, none of which are doughnut shaped.
I actually did a review of various alternative fusion systems and as a result I actually invested several of hundred thousand dollars into Tri-Alpha Energy. So I know exactly what's going on in that field. Polywell basically failed to show that its scaling laws work. It might still work out in the end but there are reasons to believe it won't.
Tokamaks are still the safest bet. A commercial power reactor will be smaller than ITER and it'll be much cheaper. ITER is built conservatively with low-temperature superconductors where now we can use high-temperature superconductors. ITER also has a lot of instrumentation that won't be necessary in a commercial reactor.
Tritium is going to be produced in the reactor itself in lithium blankets. D+T fusion emits a neutron that can be absorbed by lithium, producing helium, tritium and sometimes another neutron. This will provide enough tritium to feed back into the reaction.
Fusion neutrons are actually valuable enough in itself, they can be used profitable even in sub-ignition tokamaks.
To be fair, Bussard's Polywell failed entirely. One thing about tokamaks is that we're already sure that they work, we know the scaling laws and can extrapolate the behavior.
You've just committed a "false dilemma" fallacy. A city hall can outsource technical support to a private company that operates in multiple cities. Example: http://www.insitesupport.com/i...
Moreover, this company can also be used to service the infrastructure. These days the costs of running a fiber network are well-known.
The current crop of drones is susceptible to electronic warfare anyway. Both US and Russia lost several drones in Syria trying to scout each other's forces. The future drones will probably utilize something like laser relay links and/or autonomous AI.
Back at my military training the instructors basically said that for military equipment EMP is not a problem. Because if you're in the EMP range then you're already dead from the shockwave.
Nope. Arbitration is FINAL. There are NO appeals unless the arbitration procedure was not followed.
It's entirely LEGAL for the arbitrator to be bribed, have conflicts of interest or decide a case by tossing a coin. There is NO legal recourse against it.
Nobody uses blockchain for anything serious. Some companies use it because it's a fad and they want to sound cool.
My friend just got laid off from Yet Another Blockchain Startup that was trying to create banking software on top of the blockchains. Turns out that banks don't really need to have immutable history of transactions. Basically there are no situations when it's useful, the regular record-keeping systems are more than enough.
He's promoting nothing more than an expensive joyride, his ship won't reach nowhere near the orbital speed. So you can just as well go up to "space" on a balloon.
You're in luck! Amazon Aurora is basically a different backend for PostgreSQL (just announced) or MySQL that simplifies management. You don't have to learn anything new.

Other fusion approaches it's much less clear.
It's basically a high-risk bet. I don't put very high hopes on it, but if it goes through it's going to be awesome.

Never mind what they actually do, as evident in all the long time Democratic political strongholds like Detroit, Chicago, Baltimore, etc.
Which are so much worse than Wichita, Charlotte and Charleston?
Why not look at the horror dystopia of Portland, New York and Seattle?
Hi!
You've just committed a "false dilemma" fallacy. A city hall can outsource technical support to a private company that operates in multiple cities. Example: http://www.insitesupport.com/i...

The keyword here is: "military equipment". It's already designed for EMP.
Back at my military training the instructors basically said that for military equipment EMP is not a problem. Because if you're in the EMP range then you're already dead from the shockwave.
There is still generally a convention that almost all Olympic sports involve some form of athleticism.
Like target shooting? Or curling?
There are lots of horror stories about arbitration. Like an arbitrator being a relative of the employer's lawyer.
Murder is a criminal offense and can't be arbitrated (for now).
Nope. Arbitration is FINAL. There are NO appeals unless the arbitration procedure was not followed.
It's entirely LEGAL for the arbitrator to be bribed, have conflicts of interest or decide a case by tossing a coin. There is NO legal recourse against it.
Yes, it's seriously that bad.
Nobody uses blockchain for anything serious. Some companies use it because it's a fad and they want to sound cool.

But you can get that on a regular plane, and survive it (see: "Vomit Comet").

This won't work. "Conservative content" mostly fails the "dumbass idiots" filters. China needs to filter smart content.
