Notice that the ones who talk up zero emission vehicles exhale out A LOT MORE CO2 with all their praise of the earth loving things while the detractor sums it up nicely in one sentence. So who exactly is the more earth friendly kind of person again?
Hey, here is an idea for the Greens to think about.
I wonder if it would be possible to use the Diesel engine from the generator directly in the mini digger and cut out the need to charge the digger in the first place….?
I will ask that AOC person if this is an idea I could patent?
It can’t have been done before can it….?
Here’s what the Manhattan Institute tells us about utility grid storage: (it’s insane).
It costs less than $1 a barrel to store oil or natural gas (in oil-energy equivalent terms) for a couple of months.[20] Storing coal is even cheaper. Thus, unsurprisingly, the U.S., on average, has about one to two months’ worth of national demand in storage for each kind of hydrocarbon at any given time.[21]
Meanwhile, with batteries, it costs roughly $200 to store the energy equivalent to one barrel of oil.[22
$200 seems incredibly cheep for a battery equivalent to the energy within a barrel of oil. It costs me $160 for a 5AH Makita battery, which would be probably about 1 litre of oil equivalent.
Also, the oil and coal generate the power. Batteries generate nothing.
1 million BTU, about 7 gal of diesel fuel, per hour is 29 kw of power. A battery simply cannot match the energy density of hydrocarbon fuels.
That digger comes with a 15kWhr battery as standard, with the option of 20kWhr, so roughly the same amount of energy as contained in a 4 gal jerry can…
A lithium-air battery can theoretically come fairly close, but don’t hold your breath waiting for it.
I have brought this up before, but again, How are they going to mine for all of the minerals needed for Wind Turbines and Solar Panels in 20 years.?
A few platitudes, visionary statments and a dismissive wave of the hand will fix it.
Userbrain:
They will use battery powered diggers just like this but bigger. Not sure how they will mine for the money to finance it all. That bit is very scary.
A possible, but very highly specialized application for this: excavation for rescue in confined spaces with very little or no ventilation. Otherwise it’s probably too expensive to even rent for a very short job.
Sent this to my brother, and here is his reply:
My Tesla friend says if he runs out of charge on the highway, they send out a flatbed truck and a battery pack. The battery pack has enough energy to drive the Tesla on to the flatbed and driven to a charging station. Then you have to take it in to have the computers reset.
Works great! 🤬
Glad someone posted this more globally as couldn’t find on youtube.
I’m still waiting to see the factory producing Solar Panels being powered by Solar Panels & that goes for WindTurbines also; or a Pick’nMix of the two & no cheating with FossilFuels!
Green as in geen-backs and very green, where environmental disruption is shifted… shared. Well, people can believe they are empathizing with Mother Gaia. So, just do it, kneel, I guess.
The next thing will be electric motorhomes, but you’ll have to make sure they carry a powerful enough backup diesel or petrol generator to recharge the battery.
Funny you should bring this up – I went to a motorhome exhibition today, and one of the promotional leaflets handed out mentioned a couple of new electric motorhomes. I think the best range was about 160 miles. Now imagine an average small camp site electrical distribution system if one of these plugs in to fully recharge, never mind if (God forbid) they become commonplace. As for trying to squeeze one into a typical supermarket EV charging bay…
Battery operated industrial equipment is quite common. Think fork trucks in large warehouses. Usually there are more than one battery pack per vehicle for swap out. The ones I was acquainted with were about 2x3x4 feet and weighed several thousand pounds. Also, scissor lifts for ceiling maintenance, light bulb changing, ect. Depending on usage they lasted an 8 hour shift, recharge might be 8-16 hours. You really do not want to use ICEs inside buildings.
Why would you need a mini-digger inside a building? Neither fork lifts nor scissor lifts require as much power, and I doubt if either would be used if they needed recharging after two hours of use.
It boggles the mind that some company spent thousands developing this, and another company bought one.
I find it fascinating that some people seem to think they are saving the planet with batteries that they charge at night, for use the next day, ie the fork lift batteries.
Where do they get the power from, solar they will tell you, my question, how? the sun doesn’t shine at night, so no solar.
They seem surprised, what are our children being taught at school, that the sun shines at night, I DON’T THINK SO, or I have yet to see it.
So where are you getting your power from, you can see the wheels turning ever so slowly, must be coal here in queensland, DUHHHH!!!!! that dirty black stuff that the govt are closing down all the coal fired stations and not planning on building any more or so we are told.
So back to the question where are you getting your electrical power from??? that you use at night.
Delivered to your job site on a trailer hooked to a (virtual) Tesla pickup truck.
I hope the “engineers” that put this thing together don’t start designing bridges anytime soon.
Is it wrong to laugh?
Well for now laughing is still legal. For now anyhow.
Are they incapable of basic math? HP x 707 watts x hours all divided by 1000 gives kwatt hours.
And this is assuming 100% efficiency.
800 hp x 707 x 10 (10 hour shift) ÷ 1000 gives 56,560 kwatt hours. Now that is a battery pack I want to see!
Someone above quoted “my ass”. NO. Much more expressive when pronounced my aRse
The reason these things exist is to allow work indoors. “Zero emissions” means one can breathe around them. Linking them to stupid political issues is malice.

Two hours of run time is actually pretty good for a battery-powered excavator. Small construction machinery made for indoor work is commonly powered by propane, but now that reasonably good batteries are available, we will see more of it run by electric motors.
Ni-Fe alkaline batteries have been in use for more than a century, powering forklifts, locomotives, and such. Their capacity is poor, but they are cheap and durable and are still widely used as indoors and underground traction power.
Yep.
From the JCB web site:
https://www.jcb.com/en-gb/products/mini-excavators/19c-1e
“JCB today makes company history with the unveiling of its first ever electric excavator – the quietest digger in its range and one delivering zero emissions.
The brand new JCB 19C-1 E-TEC mini excavator has been developed in top secret at JCB’s World HQ in Staffordshire where it was shown for the first time today.
With the drive towards lower emissions, the zero-emission JCB 19C-1 E-TEC will allow contractors to work inside buildings and in emissions-sensitive inner city environments. It will also allow rail contractors to operate in tunnels and underground, without having to install costly exhaust extraction equipment.
Another huge advantage of the new electric mini is that the external noise, at 7dBA lower, is a massive five times quieter than its traditional diesel powered counterpart. This means contractors can work after normal hours in urban streets without disturbing residents, as well operating in other noise sensitive environments including hospitals and schools.
On digging there is no compromise on performance with the fully charged electric machine capable of putting in a full shift in normal operation. And with no daily checks of coolant and engine oil levels required, the machine is off to work quicker than its diesel counterpart.
JCB Chairman Lord Bamford said: “JCB has been at the forefront of developing innovative, low emission construction equipment for many years. In producing an electric JCB mini excavator, we are offering our customers a practical and affordable solution for applications that demand zero emissions and quiet operation.”
JCB Chief Innovation and Growth Officer Tim Burnhope said: “By replacing the diesel engine with an efficient, 48V electrical driveline, with the latest generation automotive battery cells, JCB has once again moved the mini excavator market forwards.
“The 19C-1 E-TEC will provide contractors with a zero-emission, low-noise solution, allowing them to work independently, in late night urban conditions, within buildings and even in rail tunnels with no requirement for costly exhaust extraction equipment. The 19C-1 E-TEC points the way to a new zero-emission future for JCB mini excavators.”
Yes, and JCB has only moved half-a-step in the right direction by replacing the power plant in that machine. Imagine what life would be like without having to worry about hydraulics.

This video is going viral as we speak. The UK Yorkshire accent makes it really funny. Yorkshireman are known for a no nonsense, down to earth outlook.
On the subject of so called zero emissions. In the UK we still run diesel trains on our rail network. Before we mess around with battery operated cack, wouldn’t it be an idea to fully electrify our railways? I know that the electricity currently comes from fossil fuels anyway but it could be generated using nuclear power in the future. The thing is, electric trains use technology that has been proven to work, as opposed to technology that has been proven not to.
I think many of you are missing the point of zero emissions, though. – For a machine that size, it’s not about carbon emissions, it is about being able to work in confined spaces without needing a BA set.
I’m not sure about the JCB model but many of the electric/hybrid excavators on the market can be run directly from a 3 phase gen set, so downtime is not an issue.
I personally own diesel earthmoving equipment but I can definitely see a need for these types of machines.
Green reasoning and Rainbow power at work.
Coal roller triggering at work. It’s just a big cordless tool that needs recharging. Iduots forgot to arrange for construction site power?
But… It COULD run on solar-derived energy, right?
Sure, just have a mobile solar panel system a quarter of the size of a football field (larger if you want to recharge it in less than eight hours) to drive out to your construction site. Easy-peasy.
That power source is called “nighttime solar” in Spain.
