Splitter
I agree streblerm
To much to go wrong with a screw on a wheel, and the moving suspension on the other 3 wheels, and the jack, maybe sinking into the ground, or the car falling of it... Also, much to low for comfort, like someone already mentioned..
Also, relying on the friction between the wood being split and another piece of wood on the ground as depicted on the Atom video, is also introducing to many unknown variables...
Also, same applies with the "table model'... add a bar gentleman!
Atom should simply add a bar in the same plane, as the screw and problem solved, there's always a stop..
There's also the question of speed, and I certainly found that a Austin Mini Engine, behind one of those screws, gave the speed, and power needed, to efficiently split wood...
The Acorn Splitter my father in Law uses, on his 3pt hitch, Kubota 1550, works fine, a little slow for my liking, and also the screw is a little shorter, so it's more difficult to have more then one piece of wood on the splitter at a time...
Bought it for 75$ here locally about 8 years ago...
Just asked a elderly neighbour, and she new exactly who had one... No, doubt also the talk of the village at the time..
They probably shamed him into buying a Hydraulic Unit:hmm3grin2orange:
Turns out he had it stashed away in his barn and was glad to get rid of it..
A quick look on craigslist found these

Screw type log Splitter / post hole digger
