Comment: Re:IANAL, but my answer would be no (Score 1) 256

Right, the way that this should work is like the british version of the 5th - that is you have the right to keep silent, and not tell the police/court something, but if you do keep silent and don't tell the police, then you can't use that in your defense later.

Basically, you have the right to not self incriminate yourself, but you don't have the right to be bolshy and just hide information for the sake of hiding it.

No, they knew that already and took it into account when they made their formula. Then they added some other predictors, e.g. being male (already known), being able to do a strenuous task, and your heart rate being able to clock up to a decent rate.

The latter two are the new ones.

Of course, this is slashdot, and if you incorporate any past knowledge into your new work, that work can't possibly be new or informative.

If the user overclocks their GPU and it ends up overheating and breaking down isn't the responsibility for that on the user's shoulders? Why does NVidia care so much?

Normally, yes. But if the driver has explicit support for it, not so much. Basically nVidia is washing their hands of legal responsibility for you breaking your laptop.

1) You missed out the "transmission" losses for the fuel (it takes roughly 1.2 gallons of fuel on average to transport 5 gallons of fuel to the petrol station)
2) You missed out the transmission losses for a mechanical car (around 30% of your energy is lost in the gearbox/diff/...)
3) EVs are actually about 90% efficient, not 40%.
4) Power plants are roughly 50-60% efficient even if you assume you use fossil fuels to generate the power.

What this adds up to:
Fuel powered car = 80% (fuel tanker efficiency) * 26% (engine efficiency) * 70% (transmission efficiency) = roughly 15% efficient total system (ignoring the amount of energy it takes to dig up the fuel and carry it to shore)
Electrically powered car = 60% (power plant efficiency) * 94% (power grid efficiency) * 85% (charging efficiency) * 90% (engine efficiency) = roughly 43% efficient total system.

Add to that that you hypothetically in the future can then replace the fossil fuel burning power plant with a {nuclear | wind | solar | ... } one, and you get a rather huge win. You're literally using one third the power to drive your vehicle.

If at first you don't succeed, you must be a programmer.
