I love how you did not do the comparison using joules or watts hour, actually you did not compare them...
Speaking of engines, you "think" making an electric motor is easy ? think again.
Not only you have mechanical issues, you ALSO have power electricity issues (you did not have them with fuel engines)
I crunched the numbers and they are not pretty, at all.
You can convert hp to watts, I love how you missed that, and think you got me. Fuel is dependent on flow rate, and mass, as the potential energy is fixed. So in order to compare energy over time, you simply have to know the fuel flow rate and the efficiency of your engine and the energy density of the fuel. With electric motors it's a bit more complex, because the flow rate is dependent on voltage, current and resistance. Efficiency is much higher with electric though, 80-90% efficiency is common.
As far as electric motors, I never said it was easy, if it were, any asshole could do it with a 3d printer. As an engineer I understand how engineering works, or I wouldn't be one.
With combustion engines you have other issues, I've been working on combustion engines for a long time. By comparison, my understanding of electric motors is limited. Combustion engines are much more my bread and butter, anything that deals with air really.
I can fill a 500 mile tank with diesel in about 10 minutes.
I can recharge a 500 mile cell in about 24 hours.
My time is worth something.
This is important, an emergency situation such as a storm may require a 10 min fill. Also you can carry fuel, it's harder to carry more range for a full EV.
power multiply time is energy
watt is a power unit, horse power is a power unit, there has to be a way to go from one to the other So, a google search result in https://www.rapidtables.com/convert/power/hp-to-watt.html
you still are not doing the proper math, you probably did it some time ago and was scared of the result
Not scared of the truth. Energy is power over time, and power is a time averaged measurement. So you're using a time average of a time average to derive some core value. Perhaps you're underestimating the comparison. I said at a flow rate of 100kg/hr 1kg of diesel at 30% efficiency will produce somewhere in the realm of 700hp. Those 700hp cannot be provided by any battery for an hour straight, there are no batteries that can hold that kind of charge. Turbine engines, diesel engines/piston engines in general, can, as long as you have a big enough gas tank.
I like my vroom vroom more than electric whirring.
