You better get used to it. RAM is going to move closer and closer to the CPU for speed and power reduction. And every major laptop manufacturer will move that way to compete. Especially now that the M1 Mac has shown what’s possible when e

That sounds like a ridiculous assumption. Airplanes are basically guaranteed to not discharge the batteries lower than 20% for safety reasons. I’m guessing they’ll also not charge to fully 100%, like some BEVs. On fixed routes they could ch

From what I’ve heard you just need to let the reservoir “recharge” for about 30 years to get the heat back. So worst case you need to build twice as many geothermal plants. It’s not that different from nuclear power plants that need to be d

Not using cobalt for batteries doesn't solve the problem. Batteries is not the only place we use cobalt. It's used in fuel refining for instance. I really don't get this.. why do some people seem to think that not buying EVs

The game is cheating a little bit, since it loads a lot of read-only data from external SPI flash memory, and all the code is in the internal 1MB flash. On your 386, everything including the OS had to fit on that 4MB RAM. It also doesn&#x27

Norway has several dangerous mountain crossings where you need to wait for a long time so you can drive behind a snow plower. This country is like a worst case scenario for EVs in this regard. Yet the share of EV sales is over 50% now. Here

It’s not the lithium which is dangerous with li-ion batteries though. It’s the flammable liquid electrolyte. That’s what gives you explosions and fire. I think the lithium does make it harder to put out after it has caught fire though, but
