And what is the problem with a gas hybrid heat pump? It's an ideal solution for places that get very cold, use the gas furnace for the weeks when it's below -5 and use the heat pump for many months around that. It's one of the most efficient ways to use a heat pump as you don't have to bully it through the coldest part of winter with very bad COPs, you're only using it when it's most efficient. And when your heating period is very long, that will only benefit your seasonal COP. So of course it's more expensive than a simple furnace, but it will also save loads of energy and redeem itself after 5-10 years.

The best part about this is you already have an AC, aka a heat pump, but you don't use it for heating?

Lightning doesn't have near the capabilities of USB C. ... pretty clear that USB C is superior.

Are you talking about the capabilities of the USB protocol 3.x, or the mechanical design like I was? I don't know a single property where the mechanical design of USB is superior to Lightning, but I'm ready to be enlightened.

Okay, I suppose you wouldn't do that when replacing and old furnace but rather go for a hybrid system. In Europe loads of people are reacting to hiked gas prices and have perfectly fine furnaces in place that they don't want to get rid of.

People think that's a killer argument against heat pumps when it absolutely isn't.

In that sort of climate you get a hybrid system or just leave your old furnace in as backup. You'll use the furnace for the couple of days/weeks when it is below -25c/-13f and use the heat pump for the 6 months around that time window and save huge amounts of energy because you only use the heat pump when it's most efficient. A hybrid system will improve efficiency because it combines the technologies at transition temps while just keeping the old furnace as backup is obviously much cheaper, since you can also get a smaller unit than you normally would because you don't have to worry about the coldest period.

My thoughts too, with a pig being opposed

"Black, green, peppermint, chamomile, melissa, ginger?"

10 minutes later you get a hot cup with a bag in it, no clue how long it's been sitting in there already. Usually a bag of sugar and/or a cookie on the saucer.

I mean, it says cybertruck parts, not the whole thing including assembly. Certainly possible for some manufacturing processes under given conditions to produce parts with ±0.005 tolerances like laser cutting or precision CNC machining of small dimensions. But it's obviously completely unrealistic given that most parts for a car will be of large-ish dimensions and stamped, injection molded, cast, forged, extruded... none of which lends itself to IT grades better than 10, far away from talking about microns.
