Well, it's obviously a typo. The headline should have read "010 Years of Intel Processors Compared".

You've been waiting "a couple of years" to upgrade a CPU that is less then four years old? Just how long after buying it did you decide to upgrade?

Clearly the government outsourced all intelligence work to Facebook. Facebook now has ELINT drones. Optical reconnaissance will come next, I presume?

In Japan, getting arrested is pretty much like getting convicted.

In Munich?

Also, e-bikes decrease your workload.

I wonder, then, why don't I have a "simple and efficient" SSB transceiver in my cell phone...

Relevant?

To my knowledge, these converters are still fed from matching AC transformers. Granted, that's mostly because AC is what the whole station is connected to. But since technology keeps marching on, we'll probably see a day when direct LVDC to HVDC converters (for example, for utility-scale PV) will be a commonplace affair.

And yet, in practice, HVDC is still more efficient than current AC lines in the end, even if still somewhat more expensive at the moment.

DC gives you efficient long-range transmission. I.e., that "epic scale" you spoke of.

Too complicated energy pathways. You can't power everything by heat. If your cooling needs are saturated, you can't power anything else with it. So you need a parallel supply of electricity again. And once you have it, why the redundant heat engine in the first place?

Actually, it doesn't.

Maybe you could always have a mid-level AC grid or something similar (below long-range HVDC and above municipal DC). I assume that fewer large inverters would be better for the overall economy than every small PV installation having their own stuff.

Possibly, but maybe it's simply cheaper for the manufacturer to simply sell 95% of the same product plus different power interfaces. I've long thought that whole local power grids would switch to DC eventually anyway. With broader deployment of PV technology (and potentially power-to-gas) and improvements of power electronics, it only makes sense.
