When we get electric tractors, will the coffee get even better tasting?

It’s called the SESAM (Sustainable Energy Supply for Agricultural Machinery), and seems to be the first fully electric tractor.
John Deere Electric Tractor SESAM

Two 150 kW electric motors can be used together, or as a single drive unit, while second motor to incorporate other fucntionality, like a hydraulic pump.
If you Google "electric tractors" and click "Shopping" there are lots of smaller ones on the market.

If it carries the batteries like a Tesla it should be good on side-hills (the tractor killer).

Wrong thread because it's too aero?


Just A Car Guy: An expensive and luxurious Maybach converted into a company car for a sharpener - Auto & Technik Museum Sinsheim


Just A Car Guy: 1938 Mercury convertible ended up in Italy by way of a service member who was stationed there. At some point, it was converted to what is called an “autostarter” for horse racing. It's now in Vicentina, Italy with a $24,50

I think so, because a hot dog has a nice long aspect ratio.

I would love to see it in a wind tunnel with smoke blowing about to be sure though.

What’s The Greatest Car That Was Never Built?

One car springs to mind. You might be surprised to know that Henry Ford and Thomas Edison were good friends, and Ford admired Edison a great deal. Ford built his own electric car in 1913 (pictured above), but in 1914, the two collaborated on a project to build an affordable electric car. It was going to use Edison's own battery technology, but both their car and battery workshops burned down in a fire.

I'm not sure how they steered that thing.

The yellow pontoon body could use attention to the stance and wheelwells.The upper body starts out well, then transitions to what I'd call a high-tailed stinger.




I doubt there is much downforce at the rear.

Maybe like a tank? If you want to steer left, to divert more power to the right wheels and less to the left.
