Already possible, in principle. There's an electrically powered UAV being trialled for delivering a 25kg payload at ranges of up to 50km at the moment. The thing weighs 130kg and is autonomous once launched. Something like this is probably pretty hard to detect and shoot down, given that it will have little or no IR signature and only a small radar cross section. Swarm attacks with vehicles like this could be as effective as conventional bombing, despite the much smaller payload, as they have the potential to be far more accurate (pretty much fly in through a specific window accurate).

Depends what you mean by green. Nuclear power is extremely poisonous, but is controllable, and does not trash the planet from normal use. Greenhouse gases such as CO2 and methane, (the latter from farm animals, cattletruck), might change the climate and this could threaten life.

Venus has had runaway global warming, (for different reasons to the Earth), and its surface temperature is 464°C !

Sounds like a platform for nuclear weapons as well (the vintage W54 warhead had mass of approx 23kg). Should be rather devastating even without a swarm.

Modern version of "Blitzkrieg" could be the Shockwave... and "all our current AC are DC..."

I've wondered why Vlad hasn't looked at using something like this against his opponents. Got to be easier to get a small electric drone to release a nerve agent right up close to someone, from a safe distance away. Easy to make sure the target has been correctly identified, too, given that even toy drones have video links.

Vlad the Pantie Poisoner is much more catching than Vlad the drone sprayer. One has to leave his mark in underwear ....errr, history

We’ve already got an unmanned aircraft to deliver a bomb, even nuclear over hundreds of miles and in swarms too, expensive to build but fuel wise very economical they call it a cruise missile

I regularly visit three other centres as part of my day job, all by road.

The nearest is 300km away. So I can drive down, get the work done and drive home between sunrise and sundown. Going electric, if you can recharge in 90-120 minutes might be doable.

The next is 1000km away. so its a two day trip with work in the afternoon of the first day and the following morning.

The third is 1500km away. 10-12 hours to get there, a day for work and 10-12 hours back on the third day.

Going electric and factoring in the need for regular recharging, the 100's of kilometres between potential recharge sites and the desire not to be driving at night will potentially add days to these trips.

Until they come up with a rapid charging system supporting a high speed battery range of 1100km its not viable for our local needs.

But I'll be retired before they fully replace turbo diesel with electric, so it's not my problem.
This so sounds like a wind up... drive 1500km one way for a one day trip? And in 10-12 hours.. I don’t think so. What a waste of manpower. Fly and save the company hundreds!!

It doesn’t take 90-120 to recharge. You can recharge up to 80% in under 20 minutes.

Oh and you comment on “not viable for our local needs” and then go on about trips hundreds or thousands of kilometres away... um, not local. Dominic Cummings would love your idea of local.

Doubtless, for some uses liquid hydrocarbon fuel is indispensable. That does not mean fossil fuel; synthesised fuel is surely possible, hopefully with carbon sequestration. It will require energy inputs, but the outputs of some sustainable energy sources are not a good match for demand, so such a process could use excess power. Doubtless, this will be expensive: to modify a phrase often found here, "If you think sustainability is expensive, try out-of-control climate change."

On small nuclear reactors, there's an interesting YouTube lecture:
The lecturer is a bit mannered, but he is pro-nuclear, and seems to know whereof he speaks. The devices he's talking about are perhaps a bit large for forward military installations; maybe an atomic battery would be a better fit: Atomic Battery (Wikipedia) I imagine, though, it could get messy if one of those took a direct hit.

The advantages of electric transmission are very real: the series hybrid or range extender layout is a solution to the problem of recharging batteries in the field.

I don't do it any more, but when I was younger I used to routinely drive 800+ miles in a day (high was 1,100 miles in 16 hours). Usually caring or pulling something that it would be impractical or impossible to bring along on an airplane. I could add ~300 miles of range, relieve myself, and grab a to-go meal in a ~10 minute stop.
Doing that in any currently available EV would be a challenge...

Australia ain't Great Britain. The people next door can be several hundred miles away...

but with a landrover you only need a couple of spanners and a medium and heavy hammer and some fence wire to get you home. A Toyota need two technicians a customer service consultant a computer reading engineer and a workshop.

Probably not very much. The MoD stopped buying Landrovers when the Defender was discontinued.

You must be thinking of Defenders? Not all Land Rovers are created equal.

And OLD Defenders. I looked at the new one, want something with reasonable offroad chops when I move back to France (nothing will ever replace my Toyota FJ, sniff). The new one is as much of a technological nightmare as any other new car, with added Land Rover build quality (i.e. none). Plus, it's ENORMOUS - 2m wide, 20 cm more than e.g. the Rav4 or the Disco Sport. Clearly made 100% with the US in mind, won't fit in a parking space in France or anywhere else in Europe. Shame, because it does look as though it's the best new offroad vehicle available now.

I (very briefly) looked at bringing my FJ from Dubai when I retired to France. I could probably have made a huge profit selling it on after a year, but it would have been a very expensive year.

Actually, any SUV with serious off-road capabilities is becoming an endangered species. On this side of the pond, the Jeep brand SUVs used to retain serious off-road capabilities, but even the new Jeep SUVs are rapidly loosing that ability. It's rapidly getting so that if you want something that is serious off-road, you need to go for the dedicated capability (e.g. the "CJ" (Civilian Jeep) type vehicle).
There is simply too much money and too much demand for the Soccer Mom luxury SUV - that will never face anything more serious than a few inches of fresh snow - to bother to retain the serious off-road capable SUV.
