Its a terrible system. If we assume that the financial sector is good for society, then a productive element of it is idling causing inefficiencies leading to higher fees. If the assumption is incorrect, then the financial sector is not a p

Btw, all these analysis are valid for EV cars too. EV cars are terrible for CO2 emissions. because their battery packs are too big.

Well, what can I say? Do the math! One EV truck = x amount of batteries. Per the article, 700kWh One F150 hybrid [1] = y amount of batteries. Per Ford, 1.5 kWh [2] One EV truck = x/y F150 hybrids, or 500 pickup trucks. 500 hybrids pic

I knew one guy who was working for a company that did that. Bit it's not an ideal use of batteries. Semis avoid cities, they avoid stop and go. Long cruises negate the hybrid advantage. Where hybrids shine are in heavy vehicles that do

This is about large battery powered EVs, not grid powered ones. Also, it doesnt matter if you can swap a battery, or charge a fixed one in a microsecond. the problem is the opportunity cost of using a lot of battery to electrify one vehicl

Which problem? Please be more clear, more specific instead of using slogans. As I understand you want to cut emissions, reduce it to zero. Fine. EV vehicles generally, and EV semis in particular, are a massive impediment to the rapid decarb

Even if I concede your premise that our pressing need to decarburize, I am not clear what it is you are proposing. Surely not fast EV adoption! I specifically point out that rapid adoption of EVs at the expense of hybrids given limited batt

Not quite. otto cycle is most efficient at full throttle due to throttle valve pump losses. Diesels are most thermodynamically efficient at low throttle because it takes time to combust the fuel. During this time the piston expands and the

Batteries on semis dont make much sense to me. Hybrid systems on heavy inner city vehicles make a lot of sense. As do hybrids in mountainous areas. But long distance hauling? BS. Semi engines are large with very low power to displacement ra

And its a healthier attitude that existed even in America before the war. However these kids aren't living in their mom's basement because the culture has changed but because the economic and social outlook is collapsing. Our soci

Diamond and gold are far from useless. Quite the contrary, they're way both too expensive to use in applications where they'd be ideal. Copper is used as cheap gold Mica is used as cheap diamond.

So I guess we should expect Trudeau to distract Canadians on their collapsing relationship with India by having the CBC launch a series of documentaries on the letters Hitler exchanged with Gandhi.

My guess: Recording equipment tended to be large and media expensive. There was magnetic wire recording technology, which was relatively compact, but the amps still needed tubes and the machine hardly concealable.

Americans abroad shouldn't pay taxes (since they get basically no benefits) or vote (why should those who live abroad affect the laws they are, largely, not subject to?) Canada's rules are like that and I like it!

by thsksbd 3y ago
That brings up very interesting questions: To which state would one owe taxes to since you're no linger a resident? Similarly, Americans abroad vote, but ppl in DC (not a state) cant? Can I avoid state taxes by sojourning in DC before

I know when school starts. Thats not my point. The DST want to force more light onto people when research is pretty clear we need less (although we need more sunlight, ironically) Solution: They wake up an hour earlier, go for a jog, have a

The point is to use local time for local things (store opening hours, school etc) and gmt for everything else.

Well the daylight savings advocates who want to force 10 pm sunsets on everybody can wake up earlier if they wish to have an extra hour of sunlight. For everyone else, no. We cant sleep in for an hour.

Once airborne, the little droplet would be below the critical radius of water and have to absorb heat from air and fully evaporate.

Good answer, but don't forget the 90s Quebec ice storms weren't far from where you are. A week or two w/out power would suck.

Why all electric? Your plan seems big enough that you'll have multiple outdoor units. Why not have a gas furnace instead of two heat pumps? If the power goes out for an extended period of time (not improbable in the NE) a furnace will

You can get units that look like registers, especially if you have attic access. Mitsubishi has them. The only problem with them is that the installer has to do a good job with the condensate line (for when you run the AC)

Heat pumps are over a century old; 13 years ago had great heat pumps. They didn't have fancy motor drives ("inverter technology"), but they probably had better refrigerants (we keep banning them). You system is old, though, a

If the unit is sized correctly for the appropriate climate, then its broken. There's no reason the system cant deal with 0C, the COP should still be well above 1. Get the refrigerant level checked by someone that didn't install th

by thsksbd 3y ago
Simple in the sense that high school chemistry/math is all you really need + definition of COP. Its a few steps. 1. You need to get your pump's COP vs T from the manufacturer. This is the hardest part. 2. Now find out what chemis
