One example that comes to mind is the DH-91 four engined airliner. But this example also points out the main reason this approach was not used more widely - it requires very close integration of the airframe with a particular engine design, in this case an engine (Gipsy-12) designed for the aircraft and not used elsewhere.
EV is not just our little trucks[biggrin] Noticed a very cool WA based company now moving as fast and a lot more quietly into EV at a ship/ferry level.

This looks interesting. I wonder if[thumbsupbig]
Magna eBeam rear axle turns regular utes into electric vehicles
One in the front too and we are in business, a bit of unsprung weight there, not much more than a Salisbury though .
unsprung weight wont be a problem in big rigs
The present and future of electric axles
Ferries are very good scenarios for electric - known times on the water under way and known times at each end unloading and loading so battery size and charge times can be calculated quite accurately. Makes a lot of sense. [emoji106]Quote:

With more than 200 e-ferries planned, Thailand’s ‘Venice of the East’ could be on its way to becoming the electric ferry capital of the world.
A few weeks ago, on the 160th anniversary of the creation of the Thailand Marine Department, its Director General Wittaya Yamuang said “By 2021, there should be up to 30 ferries providing service before it expands to 200 ferries throughout the country in three to four years.”
EV ferries Cheaper and no pollution which Bangkok is and has been for a long time infamous for. No brainer I think.
One of the things I like about hydrogen and battery is the strong possibility many less development countries areas will enjoy a major jump by not having to install Billions plus of infrastructure. Its not just off grid survival types that can benefit [biggrin] The Asian renewable Energy hub in the Pilbara is huge scale. 100 times smaller would cover almost any large industry application anywhere in Australia and elsewhere.
Still want a Hydrogen ferry to Rottenest for my next visit to Perth. Noted Rottenest WA is only about 30% or less for water and power now. Wind and Solar 70% ish. Move a little hydrogen from "Woodman Point Wastewater Treatment Plant in Munster will produce around 100 tonnes of fuel-grade hydrogen and 380 tonnes of graphite each year, with the potential for expansion." It will be on line later this year[thumbsupbig]
At the risk of encouraging all of the Tesla and "Elon Jesus" adherents out there I just found this quite good analysis of aging Tesla vehicle issues .
As Teslas Age | Gruber Motors - YouTube
I found it very informative .

I won't do a "certain member" and post another link but if you open the Gruber link and subscribe there is also a video there of how they fix dead battery packs on old Teslas. If 1 of the 7000 cells goes bad it kills the entire battery. WOW!
I found this article on claimed ranges quite interesting. Tesla seems to be "gilding the Lily" a bit.
