It’s great that more people are focusing on making better environmental choices. Plus technology is making it more economical now, and that’s what people really notice. Wind energy, solar power, hybrids and zap EV’s, our choices are good. There are now electric cars being sold everyday, you just plug it into a regular power outlet. When people test drive them they say it’s far more fun to drive an EV.

snowscew propulsion predates WWII by 20 years. Consider Armstead snow-motor company.

Hello James Kahn,
Yes, I'm surprised to see that a Mr. Burch came up with this idea in the 20's, filed a patent and actually built a working example.
This is a good example of men solving problems by intuition. I enjoyed looking at the film showing the obvious advantages and some of the handling problems. These match up to what my dad told me about his vehicle.

My father was intuitive, solving many everyday problems by relying on his (extensive)experience.

Well, another thought comes up as to why the
Lend Lease Act preparing (enabling) Stalin for WWII did not include such a machine ( or other more suitable gear ) to operate in the known devastating winter conditions of Siberia.
What was supplied were very conventional tanks. Very many of them. Just a side thought!

I resently saw a US patent for a snow vehicle using a screw dive system from Aug. 20, 1907.


snow snow snow, look at the impact tracked and wheeled vejcles have on the enviorment. I live in Ga. and grew up in Fla. Swmap marshy and spongy logging, low impact on the land wont dig in and destroy, old ideas are found becomes "new" ideas instead of just ideas.What type of improvements keep it simple like the ford 2n, 9n, and 8n tractors, the original was built to be added to a farm tractor for winter use and removed in the summer. according to Armastead, built on a 1925-26 fordson tractor.
