People are crazy x) well at least it was laying flat on the table and not diriged at her face x)

When you think that it was just a 10g battery and we litteraly have freaking kg of them on our boards that’s pretty scray though,
I’m allways freaking thiking how bad it could get if my commuter got runned over by a car

And lithium batteries are, in fact, not more energy dense than TNT. In fact, they’re about 1/5 - 1/4 as energy-dense as TNT, at ~700 - 1000 joules/gram, whereas TNT is about 4000 joules/gram.

And yes, a candle (or gasoline) is farrrr more energy dense than TNT, at about 48000 joules/gram - More than ten times that of TNT, or 40x that of a lithium ion battery.

For reference, a 100KWh battery pack as seen in a Tesla model S/X has about the same energy content as one gallon of good ol’ dinosaur squeezings.

Chemical energy is not something we can have the greatest understanding of despite literally running off it. :rofl:

Yep. And don’t even get me started on nuclear. One pound of uranium has the energy equivalent of a million gallons of gas.

yes there is always a bit of gap between the fuel, and the machine that makes use of it.

Damn energy GET IN MY BELLY

Yup. And that’s why a Tesla can go 300+ miles on the equivalent of one gallon of gas. Electric motors are >90% efficient where the best gassers hit about 25%

(And also why hydrogen cars are fucking stupid. Yes, they’re more efficient than gassers, but only a little. Battery-electric is more better in all the ways.)
