That's really not a factor. The most popular semi truck in America, the Cascadia, is rated for 52,000 lbs GVWR. Kenworth T680 has a 64,000 lbs GVWR. Both far short of the 80,000 lbs limit. The eCascadia has a 230 mile range on a 475

Why would they? There's nothing consuming the oxygen. You don't need scuba gear to go spelunking. The only issue is removing heat, and you probably don't need much airflow to do that.

OP's point with refrigerated containers is that they are large sources of heat (since creating a cold volume heats up the external volume by a larger amount), not that they are more vulnerable to heat in the tunnel.

a 95% efficient electric motor is still creating 15x less heat than a diesel engine, and zero carbon dioxide. Traffic will carry out hot air, heat will leave through the tunnel walls, and convection will also carry out heat. At the very l

It is, and it has even been done. One large limitation is that it's not a great idea to have batteries inside the body. An LVAD is intrinsically liquid-cooled; batteries are not. Ruggedly encapsulating a battery means it is fairly we

LVADs are implanted in your chest. Blood doesn't leave your body, but do they have external batteries. You have a wire coming out of your chest (or neck/head, sometimes) which is a constant infection worry. AFAIK the only exter

Energy is not the same as electricity. That burning is for heat. Your clue is that petroleum is not used for electricity; it is used for transport and a small amount of heating oil. Biomass is 1.4% of US electricity. https://ww

> The rest is from oil & gas plants. You mean gas plants. Gas in a powerplant produces .41 kg of CO2 per kWh[1]. A Model 3 gets 4.37 miles per kWh, so 2.81 kg of CO2 per 30 miles. Even if a Model 3 is running on a 0% renewable, 100

Just for the record- it only takes about 21k miles of driving (a year or two for most people) to release as much CO2 as the production of the battery for a long range Tesla Model 3. The standard range Model 3 comes in just under 16k miles.

Ehh. The framerate doesn't actually matter that much, because in the end the actual pixel changes color at the same rate regardless of FPS. No shader is periodic at 120 Hz; they're very rarely periodic at even 10 Hz. 10 Hz is al

It doesn't suggest using integers. It suggests resetting your time uniform every 1000, 10000, 100000... etc. In values of ten raised to some (integer) power. The sole reason for picking a number like that is because programmers will

1. Integers would make the situation easier, but still overflow after ~50 days. You can't just increment delta every frame; frame times vary significantly and and if you aren't precise to the millisecond things will jump around.
