Pinnacle Engines – Cleeves Cycle Ultra Efficient Combustion Engine

By

Well, here's another entrant in the opposed piston, super efficient engine sweepstakes, it's called the Ultra-Efficient Combustion Engine and it's from Pinnacle Engines. As with many, if not most other designs, this engine is in the "we're almost there" category. It looks like it has a lot of potential, but will it be superior to the many other opposed piston variants? Until … [Read more...]

Vinny Long Legs High Mileage Vincent at Bonhams

By

One owner, never raced, very well maintained Vincent Black Prince for sale. Ah, ... there is, however, the matter of the mileage, 721,703 to be exact, but, Stuart Jenkinson, who bought the bike in 1955 for £385, says it was a reliable daily ride for decades.

Since most of us here are tool guys, we pretty much know what to expect with tool boxes, on the surface the construction looks pretty much the same, but the details make all of the difference, … [Read more...]

Quick Charge Battery Developments

By

Supercapacitors can charge and discharge quickly but their energy density is low. So how … [Read more...]

Bob the Builder Gets All the Breaks

By

Do you know Bob? Bob likes to work with his hands. He’s really curious, too. He’s always looking inside devices of all sorts, constantly tearing through those “no user serviceable parts inside” tags, to figure out how they work, voiding most of his warranties along the way, to his wife's dismay, but, though he's had a few close calls, he never seems to really break … [Read more...]
