A rather irascible person of my acquaintance used to say before he entered a class of bankers who he was engaged to instruct 'there will be no one saying in this room "I think" when all it means is that you haven't thought, you have read it somewhere, and think that it would be smart to pass on someone else's recieved wisdom without ever considering if it is true, or useful or why it was given to you in the first place, and why you are too lazy to apply critical analysis to it'.
I tried and failed, as most was tripe.
The reason for high engine power is short runways. Plus having to climb steeply to avoid noise pollution.
There is scope too for using weather conditions more to improve range.
You never understood anything about what this man was talking about - a recent vid:
Many are looking at ways of reducing battery draw by assisted take off.
Hybrid planes will probably be first on the market using electric to take off and land or over urban areas.
Electric cars are here to stay. Anyone living in a city and not considering an electric car if buying new, is a fool. Hydrogen fuel cells will be used in large vehicles: buses, trucks, ships, trains, etc. A Hydrogen fuel cell train is operational in Germany. A hydrogen trial will be on the Liverpool-Chester line via Runcorn. Alstom are in Liverpool with hydrogen being made at nearby Stanlow.
Also Liverpool's metro is to trial this year hybrid 3rd rail electric/battery train to extend the network onto unelectrified lines. Two trials, one extending from from Ellesmere Port to Helsby, meaning train from Helsby can run into Liverpool's underground stations. And similar from Ormskirk to Preston, giving Preston access to central Liverpool. If successful using the new Swiss rolling stock, designed to be adapted for battery/3rd rail/overhead wires, other parts of the network may be in line for extension. Very cheap way of doing it. The batteries are recharged when running on electric track and at terminals.
DfT has suspended all new line electrification in view of battery and hydrogen train introduction. Only existing projects are going ahead.
And you didnt understand it either. Its an adverstisement dummy. # Tesla gets huge amounts of goivernment grants to sing a green song.
Without that it isnt commercually viable.
Oh dear. You love to Believe don't you?
As I pointed out, they may be looking, but its a pointless exerciuse.
Totally pointless.
Right, and your degree in engineering was gained when, and where?
I mean why do you bother? Are you REALLY that stupid? Even for a millennial it seems amazing that you have even survived to the stage of being able to post on usenet.
Oh. You use 'google groups' = there is after all no hope for you.
That is why planes taking off over water (estuaries like the Thames and Mersey) makes more sense. Long slow climbs and not over people poisoning them and ruining their ears below.
He didn't even notice the titles were "why DON'T we have electric planes?"
The reason for high engine power is that when one fails the other has enough to fly the plane
The total amount of fuel used to get to altitude is not affected much by rate of climb.
Once again you display your utter ignorance of aerodynamics
It is a lot better than your knowledge of battery advances. How is the rocket ship coming on?
That was my immediate reaction also. 'This is a marketing exercise, painting a nice rosy picture, like they all do'.
No, it isn't. Why are you persisting in your delusion that I am developing rockets. I am not Elon Musk. You are the space cadet, not me
John is that wet behind the ears he believes that s*it.
Now that idea was abandoned post-WW2
Just to put things in perspective, even the most powerful version only managed about 75 bhp/litre.
Good in its day, but things have moved on a long way since then.
Climbing more slowly might reduce work against drag, but it is not going to reduce the gravitational potential energy that has to be bought.
NASA, Boeing and Imperial Collage are working on giant 2,000 seater flying boats with passengers in the wings. Will be trans-ocean only. Makes eco sense. Airports can be in estuaries with high-speed rail linking them to city centres. One on the Thames estuary and one in Liverpool Bay (or Mersey estuary). Most of the UKs population is between them, with them only being half an hours train ride away. All other airports can be decommissioned. Estuaries have as many runways as you like. The waters can be calmed by wave electricity generation - like nodding donkeys.
Now you know.
How is the rocket ship progressing?
Cue nodding donkeys...
Link???
