  • Well, yes, but also no. The heat released by fossil fuels absolulety increases the total energy of the atmosphere, but the other half of a zero carbon society is that it is powered by renewable energy sources.

    If we are generating electricity by slowing down atmospheric winds or capturing sunlight incident on the planet surface, then any “waste heat” from the usage of that electricity will be energy that was already present, and therefore have no net heating effect.








  • Oil changes dont require a lot of tools. Most cars you’d get away with just a socket, a drain pan and a filter wrench. I’d be suprised if it took two oil changes to pay back what you spent on tools through the savings of doing it yourself.

    If you can afford to drop a hundred bucks on a decent socket and spanner set, then there’s even more savings to be had from doing your own brakes and basic part replacements







  • This statement about cpus isn’t entirely correct. In the manufacture of precision electronics, there is always a reasonable chance of defects occurring, so what happens is that all the parts are built to the same spec, then they are “binned” according to their level of defects.

    You produce a hundred 24 core cpus, then you test them rigorously. You discover that 30 work perfectly and sell them as the 24 core mdoel. 30 have between one and eight defective cores, so you block access to those cores and sell them as the 16 core model. Rinse and repeat until you reach the minimum number of cores for a saleable cpu.

    This is almost certainly not the case in car manufacturing, as while you could sell a car with defective seat heaters at a lower price point, what actually occurs is that cars with perfectly functional seat heaters have that feature disabled until you pay extra for it.
