I'd have thought that with modern solar panels, the option for vehicles to rest-up during the day while recharging batteries from a modest solar array, then move silently at night, may be attractive for some requirements in some places.

actually, on this I must disagree. With hybrid technology you can add more power without compromising the diesel engine (smaller engine, less weight, lower tune up), have more performance (eg electric motors on wheels giving accurate guidance of power to the wheel that has grip), the technology is way more simplified than traditional power train (imagine being free of the design limitations of the traditional power train) etc. So you can have all wheels ran with electricity and have a small diesel engine acting as a generator. And you can add batteries as well.

Effectively you have a unit that goes on even with one or more wheels missing (all wheels independent), has two power sources (batteries and diesel) and gives you freedom in design. And gives much better mpg (imagine the logistic chain on fuel).

In essence hybrid has much more benefits than just ecological ones.

That's if you are a manufacturer.

Technology is simply amazing all due to electronics and computers in various forms, as toys or consumer electronics the demands are not too great, motor vehicles and certainly aircraft, need much better quality systems which is why they are expensive. In the near future we won’t be able to “drive” the car, everything will be regulated, so accelerating faster than the next guy is not going to matter. I didn’t buy my EV to “go faster” but because it’s new technology, cheaper to run and has big tax concessions, it certainly is very smooth having no gears, fast too, just effortless but I ain’t going to be racing anyone.

Direct sunlight provides about 1kW per square metre perpendicular to the sun's rays.
Current commercial solar panels achieve around 20% efficiency maximum; 200W per square metre, facing the sun, in clear sunshine.
You'd need tens of square metres to get a useful daily charge even in clear summer weather.

Of course. But apparently this is how it is seen by customers (private sector and public sector) as well, as the hybrid technology is currently very strongly researched and is invested to. Even in the military. And not only light applications.

The use of hybrid power in military vehicles has been worked on for many years now. Around 2004/5 I spent a day at Chertsey being shown around a technology demonstrator, around the size of a Warrior, that started development back in the 1990s.

This Textron UGV is a pretty good example of a hybrid or all-electric armoured vehicle: https://www.janes.com/defence-news/n...-ripsaw-m5-ugv

Ferrybridge, Drax & Eggborough power stations, in Yorkshire, sit directly above the Selby coal field. They could lcoulcoal trains, at Kellingley Colliery, deliver them to Drax. Return and reload for a second trip and be back in time to clock off before tea.
Now, the Biomass, 3x the volume but 1/3 the calorific content comes all the way from Canada, by ship and train from Liverpool.

I'm told that the Range Rover versionversion manufacturer's range of 31 miles per charge but, none of the publications that have tested it have achieved that.
Home to work is 35.6 miles.

thank you, these very well prove my point.

There is no doubt that military vehicles CAN be built with electric or hybrid power, the controversy is wether they would be better on the battlefield than other drivetrains, there is no other reason.

That was definitely the only reason driving the research programme I saw. There's been a long-standing UK research thread looking at ways to reduce the logistic support requirements for battlefield vehicles, starting with understanding if they could all be switched to a single fuel (including aircraft), to avoid multiple supply types, then focussed on reducing the amount of fuel needed at the front line. Around 25 to 30 years ago electric drive technology had reached the point where it started to offer technical advantages, like getting rid of conventional transmission units, reducing the skill level required to drive some heavy vehicles and improving vehicle performance. One big advantage of electric power is that it gives full torque at zero rpm, very useful for both getting heavy vehicles to accelerate and for enabling things like traction control on wheeled vehicles with multiple driven wheels. With a motor at each wheel it's possible to control the torque delivered at each wheel pretty precisely, and use better torque vectoring methods than are possible with conventional mechanical transmission/brake systems.

I fully understand your saying, and that is exactly why it is being researched. So no arguing there. The thing is that the hybrid technology is evolving very fast, and I can't even imagine what it might offer in 5, 10 or 30 years. Men wiser than my self have known to be very short sighted.
“I must confess that my imagination refuses to see any sort of submarine doing anything but suffocating its crew and floundering at sea.”- H.G. Wells, 1901
"I believe that the value of the horse and the opportunity for the horse in the future are likely to be as great as ever. Aeroplanes and tanks are only accessories to the men and the horse, and I feel sure that as time goes on you will find just as much use for the horse—the well-bred horse—as you have ever done in the past." - Sir Douglas Haig, 1925

Various world Navies have been using Nuclear power to run their larger ships and subs for decades now- no reason why the new models of miniature reactors being developed could be deployed in the field to charge vehicles.

It's a great pity, IMHO, that we didn't press on with developing small packaged nuclear plants, using submarine and ship technology, before now. RR have come up with their Small Modular Reactor (SMR) concept: https://www.rolls-royce.com/products...eactors.aspx#/ but I think this could have been done years ago, if it wasn't for the anti-nuclear lobbyists. It seems that the technology exists to build large, containerised, reactors, just needs the demand to be there to make development worthwhile.

I've been listening to Bill Gate's latest book (How to avoid a climate disaster... catchy title) and I'm growing increasingly convinced that SMRs are going to be an integral part of electrical generation moving forward. They may not be as "clean" as some green lobbyists would like, but until there is some major energy storage breakthrough I feel like they're going to be quite an important crutch to lean on if we are going to come anywhere close to meeting energy needs in the coming decades without burning everything in sight.

Bill Gates is just another sorry little Hitler who wouldn't have these opinions if he knew how to properly cook meat on a barbecue.

Back to topic. Another advantage of an EV over an ICE is should you roll over your vehicle slowly and end up upright, you may need to drain the the fuel out of the combustion chambers to avoid hydraulic-ing the engine and completely destroying it. This involves removing the spark plugs and cranking it over a few turns.

Fuel not just for vehicles but also for generators.

Quicker they can be free of fossil fuels the less vulnerable they will be!
Good point. Let's go all-in for this lecky idea: here's a good one--electric bombers (carrying electric bombs of course no nasty TNT).

All this political correct electric-euphoria is just a hidden campaign to move to way more not so political correct nuclear energy use. As this is where the power needed for all those batteries will have to come from. What a happy little green world.

Wow, a lot of first class research obviously went into that statement.
