Recently with e-VTOL’s and Urban Air Mobility we have pretty similar situation as with electric taxis back in 1900’s.

In 1901, 38% of the cars were electric, and 20% were petrol.

If you'd asked the great experts of their age in 1900 which technology would come to dominate the motor-based transportation, most would have said electricity.

The Electric Vehicle Company, doomed to become a victim of its own business malpractice, was partly responsible for the demise of the product it was named for.

Founded in the final years of the 19th century, it rose to prominence with its Electrobats, considered the first truly useful electric car for day-to-day transportation.

The company pioneered a taxi system of leased vehicles that used service stations for quick battery changes and repair work.

In 1899 a syndicate of prominent car manufacturers took over the rising company to form the Lead Cab Trust, which hoped to develop a monopoly across the US.

It was the largest motor car manufacturer in the USA, but lost its position only two years later. It faced rising competition from petrol-powered cars.

The great hope of electric vehicles did not outlast the first decade of the 20th century.

By 1910 we had the Model T, the iconic universal vehicle, that was able to do everything that an electric vehicle could do and more.

In 2020’s we have similar situation as electric taxi cabs in 1900’s , lack of battery power. Despite many promises e-VTOL’s with weak batteries will remain for decade or more.

People frustration on eVTOL capabilities in Urban Air mobility could cause whole VTOL industry demise again as it happened in 1900’s with electric cars .


From Author :

Jetcopter vtol as other +330 worldwide projects could be also electric and electric versions in general are the easiest to build . Jetcopter is not satisfied with 20 min flight time and can’t cheat investors on performance numbers or promise incredible performance  ‘’when batteries will improve ‘’. That’s why Jetcopter to develop VTOL with ICE first. Reliable and powerful ICE today will ensure sufficient propulsion needs for safe flights. The sky does not forgive mistakes, there will be no chargers, no emergency stops, no recovery options , the only you can rely – on your engines and full fuel tank.

Exciting news - Jetcopter vertical technologies finished to develop also multi engine airplane , based on same propulsion system as in Jetcopter , but it will .... plane , that will take off ... vertically .  Stay tuned for more news.

People's dreams of flying cars have been around for a long time.The advent of small, powerful electric motors opened ''the window of opportunities '' for hundreds of inventors to create ''own'' electric flying car , while ''VTOL OEM rests on one's laurels''. It looks attractive to take a glider and add electric motors at any place you want. But reality is deiferent ... not so easy , not so fast ...


While inventors commend the possibilities of electric motors, they not mention anything on the batteries.

So :

1.Assumptions of future battery energy density are unwise.

2. Overestimation of present battery energy density is unwise.

3. 250wh/Kg may be presently theoretically achievable. For the installed system it never is.

4.Battery charge times and battery lifetimes have to be practically addressed.

5.Thermal failure modes of Li-Po batteries have to be addressed and mitigated.

6.Current installed battery/electrical drive systems are approximately 14 times heavier than a turboprop system burning JetA.

7.If you will be 14 times heavier , you will need 56 time more power...


WHAT TO DO ?


1. Take a small battery.

2. Reduce payload to 1 pilot + 1 passenger .

3. Get 20 min of flying time at ideal conditions.

4. Look for those to whom it could attract ...
