True, we can optimize the cycles more. Like double expansion piston engines, or that crazy proposal for a hydrid steam-mercury super high pressure power plant.

I’ll believe it when I see it. They have so many material science challenges ahead of them and aren’t very forthcoming with progress.
Unfortunately, there’s no way to get energy out of waste heat that won’t be spent pushing that heat a little harder. Already a significant amount of energy is spent cooling data centers, any attempts at energy recapture will just make that cooling harder.
The best we can do is something like district heating, because heat pumps can get over 100% effective efficiency.

1·9 months agoI wouldn’t say a normal CPU is inefficient at graphics or cryptography, rather that a specialized GPU is particularly efficient at those tasks.
We only consider a CPU slow at these tasks because of how much faster a GPU is with them, but we never see how much worse a GPU is at general conputation tasks, because of how stupendously bad it is.
As soon as operations need to share info, the GPU speed advantage is gone. Branching paths bog a GPU down with redundant execution. Latency is quite poor too. And exceptions & interrupts are basically impossible at the system level. Trying to run normal programs on the GPU would be a disaster.
Bayberries/waxberries aren’t really smootth, and Yewberries aren’t very bulbous.
Haskap berries are lumpy and mealy, are they not berries?
Do groundcherries count with their paper husk? Tomatillos? Cherry Tomatos?
Are cherries berries? Rose hips?
Cherry chili peppers are bulbous and smooth, are they berries?
Raspberries and blackberries often have little hairs growing off of each fruit, does that mean they’re not smooth? If hair is ok, kiwifruit are bulbous, but hariy.
