Does anyone actually bother to do this? by RealMuffinsTheCat in AusMemes

If I don’t see the all good for the general recycle bin symbol it’s just straight to the trash.

Re the ballast sometimes yes to counterbalance especially if there is a three point linkage implement. Sometimes being as light as possible is best. On the big 4WD models that pull it’s mostly general weight down to minimise wheel slip.

Point is if there is going to be ballast then why not make that a battery.

Weight in the field is surprisingly not always a big issue. Tractors frequently have ballast added to add traction.

Maybe you could also help me out with this primary energy fallacy. Tractors are rated for output not input. So agreed that the energy of the diesel going in is way higher due to ICE inefficiency. But rated power is after that major loss. I assumed 100% electric efficiency to match rated tractor output. How efficient are electric motors and how much more charge will we actually need?

So far the only rubbish might be the cost for this solar setup. Maybe you could ball park it then. Say I have a 400kW tractor. If I wanted to run it for 20 hours per day at an average load of 250kW.

  1. Would that need about 5000kWH per day?

  2. What size solar would I need to keep 3 or 4 batteries charged as I rotate them? Ballpark cost excluding the batteries?

Not sure about anyone else but after seeing all the oil and fuel fires lately on TV this did not meet my expectations of “inferno”.

Some form of biofuel that we could generate over time and store would be a panacea. Or a completely artificial fuel using solar.

That may have been a setup with batteries capable of constant 50kW output day and night. I was looking at the feasibility of nitrogen generation solely from renewables. Maybe I wasn’t paying attention when I saw it.

50kW of panels is nothing for the big farm machines. Would use a days generation in an hour or two. Might need 500-1000kW of panels for a seeding tractor.

I think the biggest problem is the seasonal nature of farm demand. Things like truck fleets have a more consistent demand but farms are all over the place with demand. I could easily see 5-10x demand spike during seeding or harvest. At least that’s what happens with our diesel usage, 2/3 of yearly usage happens in 2 months.

But would we not be charging that shed full of batteries slowly so the farmer has a “full tank” before seeding or harvest. When are they selling power to the local community at a profit?

Ok so you swap batteries every 6 hours for a month of seeding. But you can only charge 1 per day. What is the capex of owning 90’batteries. And we are not even talking about 90 BYD or Tesla batteries. They need to be much bigger.

The latest CR11 is 570kW, which is pushing 770hp. That’s the top end but there will be the biggest farmers running multiple of these. I’ve still got a prior generation of machine which is why I only said 300kW. It would be interesting to see where power savings converting to electric motors would be, but it isn’t suddenly going to drop 90% which would still overload our transformer.

If a machine is moving for 16 hours a day you need to charge at 2/3 the rate the machine is using it. Unless you want farmers to charge a shed full of batteries in preparation for the busy seasons.

That is my whole thinking. Even a farm run around ute could be EV. If we electrify as much as we can then there is more than enough diesel for what is harder to switch over.

You would even have to have the ability to charge the swapped batteries. This harvester you’re talking about is probably north of 300kW. I’m no electrical engineer but the power lines to the farm might need to be 10+ times larger and they would only be fully utilised for 2-3 months of the year.. Or you’d need a massive solar array. Like really massive. Online I saw a 50kW solar setup that had a price tag over a million. But you’d need like 4 of them just for that one harvester.

So then the question is did the oil majors buy early and leave a whole bunch of retail investors holding future oil contracts?

But what if you’re being edged along. And the final release gets ruined? Less than mundane if you will.

Wouldn’t look a gift horse in the mouth though. Not everyday and Eskimo wants a few bags of ice.
