Why not electric tractors?

[Captain Caveman]

I saw this video short and was gobsmacked at the poor numbers electric tractors produced. Now imagine the farmers had to go electric, prices would at least triple. So imagine the cost of food in the stores and/or tariffs imposed to keep imports on the same cost level.

Farmers don't have to go electric so..............

If someone wants to build it and another wants to buy it, good on them.

You have to realize that electric is kind of like the steam engine it works but not really the best idea for every situation and will eventually be phased out. The biggest environmental threat is not cars, trucks or any factory. It is the killing off of millions of acres of trees each year.

That is just no excuse. Progressives still need to go all electric regardless of the costs in order to feel justified and secure.

The people who want to ban fossil fuels are the same people who want to ban firearms.... overly emotional twats.

Electric tractors? When the batteries have enough energy density. After all, that would free the farmer from being dependent on outside sources for his fuel. Just install a lot of solar, and he makes his own. In the meantime, electrical machinery is being used in other industries;

And more heavy equipment turning into EV's;

That time may be in just a few more short years. Five?

Thread 'Fuel Cell Technology Turns The EV Corner'

Yesterday at 12:30 AM

The idea for an electric car is attractive for many reasons, not the least of which is that an electric motor emits nothing short of a magnetic field. Better still and almost as important, it really only needs one moving part. With a wide range of high torque available, a transmission is not needed. The real bug in the hay are the stupid lithium EV batteries--- it doesn't take a Masters in EE to understand that charging batteries and carrying the stored power around is lame--- it is nowhere, man.

My favorite professor in school taught me long ago that the fuel cell was the thing...

The best way to get rid of bad ideas is to embrace them to the fullest extent possible so that the predictable surprises of the bad idea can be experienced as consequences.

So now you’re just making up random, rhetorical BS to bitch about?

Not a good look

And therein lies the problem. Batteries are low energy density storage devices. That will never change.

That mining truck in the video ran on current supplied by overhead power lines, not batteries.

I did see a video many years ago explaining how physics only allows a battery to hit a certain storage level and no more. Blimey, if a battery could have been made to store the energy that's in diesel and/or petrol, we would be daft not to go down the battery route. But as for tractors, I didn't realise it was that bad.

Wait until another Democrat president gets in, the US will go down the retarded electric route again. A stupid idea implemented by stupids.

Actually already here. CATL has batteries that top 500 watts per Kg. And several labs have batteries that do much better than that. CATL has already started producing their 500 watts per Kg, 5 years is a good figure for a lab to production for at least one of the other high density batteries.

So many whackadoodles on this board like you said that of the Prius when it first came out. Now there are over 5 million of them on highways. LOL

A kilogram of gasoline contains approximately 46.4 megajoules (MJ) of energy. This is equivalent to about 13.0 kilowatt-hours (kWh) or 46,000 kilocalories. The energy density of gasoline is also around 34.2 MJ per liter.

Hybrids are a great idea. Maybe try again?

Care to post your source for that statement? Here is one source;
"I don't know the actual answer to this question, but I know a least upper bound to the answer, and a means of figuring out the real answer.

Battery scientists have a metric called maximum theoretical specific energy; you can read about the definition in Advanced Batteries by Robert Huggins. Right now, the most energy dense batteries you can buy are lithium ion, which are in the 100-200 Wh/kg range. I don't know what the best battery is, but later in the book, Huggins shows calculations that indicate that Li/CuCl2 cells have an MTSE of 1166.4 Wh/kg. (5x the capacity of current batteries!)

We know that the highest MTSE is at least 1166.4 Wh/kg; you could use his method to calculate the same value for other chemistries, but the search space is pretty large.

I've also seen references on the internet to Li/O2 and Al/O2 batteries with MTSE of 2815 and 5200 Wh/kg, respectively. Not sure how credible those references are. Later references, like this 2008 article in the Journal of the Electrochemical Society, suggest that the MTSE for a Li/O2 cell is around 1400 Wh/kg."
