Re: OT was Alcock Brown plane zero emissions?

yes, and fairly low octane at that. The Vimy was equipped with two Rolls Royce Eagles - their first aero engines - which were V12.

"Development of the new 20 litre engine was led by Henry Royce from his home in Kent. Based initially on the 7.4 litre 40/50 Rolls-Royce Silver Ghost engine, and drawing also on the design of a 7.2 litre Daimler DF80 aero engine used in a 1913 Grand Prix Mercedes that had been acquired,[2] the power was increased by doubling the number of cylinders to twelve and increasing their stroke to 6.5 inches (170 mm), although their bore remained at 4.5 inches (110 mm) of the 40/50. The engine was also run faster, and an epicyclic reduction gear was designed to keep the propeller speed below 1,100 rpm. To reduce inertia and improve performance the valvetrain design was changed from sidevalves to a SOHC design,[3] closely following the original "side-slot" rocker arm design philosophy used on the contemporary German Mercedes D.I, Mercedes D.II and Mercedes D.III straight-six aviation powerplants. "

Nothing to do with it, The plane couldn't climb high enough to need it. Especially loaded up with extra fuel instead of bombs. Service ceiling was only 7000ft.

WWI pilots in scouts regularly flew up to 17,000 ft without oxygen too.

Is it? Do you make a habit of frequenting them?

Tesla semi seems to be 500 mile range (with the bigger battery option) and 36 tonne load, price doesn't seem outrageous ... mind you, it'll use my whole year's leccy every couple of days, or take 6 days to fully charge on a 7kW EV charger :-)

A shame Tesla's memory chips don't last as long as the battery.

Seems to have hit the news in the last couple of days, but failures were reported over a year ago. I guess they're fanatical about collecting data on the hoof ...

But it will by dyed, like agricultural diesel, to stop it being used in cars.

You know that HS2 thing? Which is costing an arm and a leg?

They are building it because the rail network is full.

And I like the way they suggest we could have a sailing ship across the Atlantic. There are reasons why they dropped out of use.

A modern prototype was built and tried around 20 years ago, it didn't work out.
