Comment who's car fills up in under 3 minutes? (Score 1) 133

the opportunity cost is that you're taking 90 seconds to fill up with gas anyway, so you're just waiting another 90 seconds.

this is what journalism has come to: Tesla has everything else worked out with such finesse and perfection that this is the only thing the writer can come up with to complain about.

And it's the only thing that can generate slashdot comments.

...what ruffled THEIR feathers?

According to TFA, they sensed low level harmonics in the atmosphere long before the storms arrived...

The most likely tip-off was the deep rumble that tornadoes produce, well below what humans can hear.

Noise in this "infrasound" range travels thousands of kilometres, and may serve as something of an early warning system for animals that can pick it up.

so why don't we start listening for it with our warning systems?

To the third power actually.

Someone didn't take thermodynamics.

I've been tracking the data myself with torque. Fuel consumption per unit time increases with the square of speed because after 65mph drag does.
But since you get there faster it's just linear increase in consumption per unit distance.

Personally, I discovered my AFR drops from 14.1 to as low as 11.5 any time the engine produces over 400 grams CO2/mile for more than about 3 seconds. On a completely flat road this works out to about 85mph or so, I can do slight inclines at 80, and if I don't ever want to have to touch the cruise control, 75-76mph.

at 55mph I get 34mpg, at 70 I get 32, at 75 I get 29.5 and at 80 I get about 27.

If I want to get there I go 75.
If I kinda want to get there I go 65.
If I don't really care or I'm feeling cheap I go 55.
