There is plenty of infrastructure. Electricity basically covers the entire country. Many many people have outside outlets that can be used to...
I calculated once that Earth could support 300 Million hunter gatherers. But whether that actually happens as opposed to the species becoming...
If it will become unsustainable. It is already unsustainable. Of course there is a need to bring it up in a post about cars. Either we live...
Let's imagine that car makers could just make up their own numbers. Would we be seeing numbers like 1000 MPG, no we would not, because once...
Sure they can. And if they can't maybe we should rethink our suburbs, our big houses at exactly 70F, and all those other things. Because the...
White incandescents are fine if you want to go that way. For LEDs it is important to get RED for the red lights.

No it's not. Who cares what the RELATIVE diffusion rates are? The thing that matters is the ABSOLUTE diffusion rate. If N2 lost 0.001 psi per...
Better inflation pressure is not a quantitative statement, so let's see if we can make it one. How about "closer to the optimal pressure for...
Sadly, I am a member of a single species. Thus, I care about mass extinctions at a species level. I suppose if I were a taxonomic group, I might...
Solar panels are CHEAP. I don't think I could buy the raw materials for what I can buy entire panels for. Currently, I can buy a complete...
Individual LEDs take about 3 Volts. It seems likely that Toyota put 3-4 in series (and then in groups in parallel), to use 12 Volts efficiently....
