If they can fly a small airliner for 30 minutes for $5. Either there's a whole lot they're leaving out. or they're not paying anywhere near what I pay for electricity.
They say the engines delivered more than 1 megawatt of power. Cool, so 1 MW over 30 minutes. That's 500kWh. Which means if they paid $5 for it. They paid 1 cent per kWh. Now i don't know about you guys. But i sure as hell don't pay 1 cent per kWh.
they also dont specify how many kwh they used. which is why i assumed a sustained 1mw of power. they also dont say how much the plane weighted. only what it could potentially carry. that doesn't mean that's what it weighted in the test.
don't get me wrong. cool stuff to fly electric planes. but i can't help but feel incredibly sceptic when they leave out a lot of numbers while making the insane claim that they only used $5 worth of electricity.
Because they didn't. And anyone that is capable of critical thought can easily take the few numbers they provide in the article and do some simple calculations.
They claim the motors pull more than 1mw of power. So using 1 mw for 30 minutes is 500kWh. That means they paid 1 cent per kWh. (Spoiler. They dont)
And nowhere, does it say the plane weighted 25000 pounds. It says it "can exceed" 25000 pounds. But by no means does that mean that's what it weighted in this test.
The most likely scenario is that the plane was bare minimum rather than maximum. I doubt even passenger seats were installed.
