Why don’t we have electric aircraft? |Tech Xplore

Why do we have electric cars and trains, but few electric planes? The main reason is that it’s much simpler to radically modify a car or train, even if they look very similar to traditional fossil-fuel vehicles on the outside.

Land vehicles can easily cope with the extra mass from electricity storage or electrical propulsion systems, but aircraft are much more sensitive.

For instance, increasing the mass of a car by 35% leads to an increase in energy use of 13-20%. But for a plane, energy use is directly proportional to mass: increasing its mass by 35% means it needs 35% more energy (all other things being equal).

But that is only part of the story.

Aviation’s flight towards low emissions only fuels the crisis | Airline industry | The Guardian

At Cranfield University, the laboratory for much of British aviation research, the transport secretary, Grant Shapps, on Thursday urged the industry “to create an electric revolution in our skies”; for the climate and, incidentally, “to seize a share of a market that could be worth £4tn globally by 2050”.

Manufacturers are pursuing electric dreams: not just companies like Boeing and Airbus, but a host of tech firms, particularly for urban air mobility – aircraft that could be clean and silent enough to make shorter air hops possible without large airports.

Heres how to capitalize on the electric car revolution without buying Teslas stock | MarketWatch

The shift toward electric vehicles is often positioned as a slow crawl, with projections typically estimating that battery-powered cars won’t outsell conventional combustion engines until 2025 or 2030 at the earliest.

But analysts who currently consider EVs as a niche product risk the same embarrassing mistake as those who panned the original iPhone as too expensive or too different. The truth is that the electric vehicle revolution is already here, and mass adoption will happen much sooner than many think.
