Johnson flips the Bozo bit, again!

#1 Post by TheGreenGoblin » Tue Jun 30, 2020 8:31 pm

The prime minister’s call for Jet Zero on Tuesday may owe more to his fondness for a punchy slogan than any realistic view of how UK aviation might develop in the next three decades.

“We should set ourselves the goal now of producing the world’s first zero-emission long-haul passenger plane,” Boris Johnson said. “Jet Zero, let’s do it!”

But as far as the technology goes, Johnson might have more luck building a garden bridge to France than getting British-made, long-haul, zero-emission passenger planes in service before 2050.

Short-range electric flight is, for the very smallest planes, already a reality. Multiple firms, including UK start-ups, are working on zero-emission eVtols – electric vertical take-off and landing craft, or flying taxis – but the concepts are primarily for domestic inter-city travel, with only a handful of passengers on board.

Battery weight and range means that manufacturers currently view larger electric planes as feasible only for short-haul flights – and even then the focus is largely on hybrid-electric, with jet fuel needed for take-off.

The big UK contribution to this vision, a Rolls-Royce-Airbus collaboration called the E-Fan X, was quietly canned during lockdown.

EasyJet, should it survive, has long spoken of its hopes for a short-haul electric regional plane, and engine trials with a partner in the US, they say, have been encouraging.

Meanwhile, work continues at Cranfield university and elsewhere, trying to convince sceptics that hydrogen could eventually be a viable fuel for passenger jets.

Plants to produce synthetic jet fuels could be part of a net-zero mix (although not zero-emission when burned in flight). Low-emission flight – rather than no-emission – is currently the overwhelming ambition of civil aviation engineers.

Johnson’s target for a UK-built long-haul zero-emission plane before 2050 may, alas, swiftly crash-land with reality.

Jet Zero, Johnson zero...

The man truly is a knob head!

What about hydrogen/electric?

In the 1970s we were told that the fuel cell was the future (along with zero-tariff nuclear electricity for the home).

I suppose I should have put this on the hydrogen thread.

What we have from Johnson though is hot air, as ever, sadly not hot enough to be part of the Brayton Cycle!

Perhaps the 'air yacht' could be scaled up?

An air galleon?

Almost Terry Gilliamnesque!

Oh Zephyr winds that blow on high

Tell me now which way my ship will fly...

;)))
