I would love to learn how to post a clickable link...

(quoted from post at 19:34:06 12/07/16) I would love to learn how to post a clickable link...

I don't know how to make it so you just click on the link but you can highlight your link and right click and open it up.

Here it is. To do this just click on the "optional link" box and stick it there. Then the next box down is for whatever name you want to give it.

Not hard at all, paste the link in the "optional link URL" line bellow the comment box you are typing in.

Jon, Have you seen the electric road tractor that the Nikola company is hoping to produce. They are already planning a gas turbine engine truck also that will be flex fueled if allowed. They are based out of Salt Lake City Utah. I looked up gas turbine truck engine and there is a video of the thing running on a test stand on You Tube. It sounds like a pulling tractor engine!

jon f mn · Dec 7, 2016

Yes I've seen that, as well as the hydrogen truck. I suspect it will be a long time til they perfect them tho.

"Regen braking" to recharge the batteries on downhill slopes? What about the guys in Iowa and such? They'll have to haul a generator around to charge it up. I guess that'd be no different than us hauling generators for our block heaters when we leave equipment in the field over night.

A little bit of math will show you how many minutes of battery life when operaring at just 50% of peak HP.
Goes to show how $$$, how bulky and how heavy battery strage of energy is vs #2 diesel.
Is there anybody here feeling all warm and fuzzy about the electric tractor ?

Right on. Tractor hp as far as I know is typically rated for what you can run all day long, whereas automobile peak hp is usually only used for a few seconds at a time. Can you imagine how many KWH of electric storage is used for just a 100 yards of tillage? Regeneration through braking is nil for a typical tractor use too.

If people didn't try new things, we would still be beating the ground with rocks and sticks. Heck we wouldn't be cultivating crops at all.

I'm sure a wise person has said at some point in our history that we learn more from our failures than our successes.

tim s · Dec 9, 2016

Yes, if we don't try things nothing new will happen, just like Turbos on tractors when they first came along most thought they would be the "Death" of a tractor engine, now even the small tractors have them and most cars and trucks..

Circa 1958 I saw a fuel celled tractor by ?Allis Chalmers? or ?IH? being shown at the Waterloo Dairy Cattle Congress. Don't know how the propulsion was handled. Never heard anything more about it. Leo

Deere tested a gas turban tractor in the early 70's but it didn't make the cut. I think IH experimented with electric motors running balers and other equipment instead of a PTO,,using a generator on the tractor, it was a good idea but motors of that day were not good enough..may work with todays technology...

And I have a hard time with 1 12 volt battery being the weak link in a tractor I could not image the nightmare a stack of them would be.

buickanddeere · Dec 9, 2016

The lithium battery packs are a absorbed glass mat type of battery with no liquid electrolyte. No partly supported plates dangling in sloshing electrolyte.
Still doesn't solve the limit charge rate, limited discharge rate, dissipation of heat, cost, low energy storage per pound and low energy storage per cubic foot.

OK to experiment with such stuff. Be a good while before such things are practical. Maybe never. One of these days they will have little nuclear reactors the size of a cigarette pack, you will put in a years worth of fuel in a grain of sand sized pellet.

Why not.

Why not ? A cigarette sized pack of 99.99% U235 won't go critical. Where will the controll rods, shielding and energy conversion system fit ?
A cigarette pack sized reactor will no more work than setting a peice of wood on fire while it is under water.
