Personally, I don't see how ya can dump 100kWh of energy into a battery in less than 10 minutes and that's what you would need to do charging up a big SUV kilowatt guzzler for 300 hundred miles of range. Even if the battery and internal wiring of the EV could take it, just the Goddamn charging cable and connector would be a serious issue and the charging location would probably need battery storage too. That's why I think we will see smaller lighter EVs, solar powered or supplemented that can charge at home without putting in a new electrical entrance and can charge from the future home PV system. Even if your solar powered compact car with a battery twice as energy dense as now only generated half the power you used on your daily commute, it would still cut your transportation costs in half if you plugged into the grid at home.

I think expense, waiting for it to charge and waiting to get one should see people selecting more efficient EVs and charging them at home mostly overnight. Many will eventually install 220VAC chargers that can top up their EV at a much faster rate than 120VAC ones.

And below -20C it does not snow because it is too cold. Or at least the engineers from Toronto seemed to think about the prairies when they designed a helicopter pad (we could keep it ice free by heating the pad). Bet we could freeze a sewer pipe in winter, talk about being up shits creek in that scenario. We get people's water lines freeze on occasion, the price of keeping the roads clean I guess.

I will be getting a new furnace next year (current one, please last that long) and it will have an air heat pump rather than just being a furnace and AC. I think they have them working to -20, seem to recall them saying -30 is on the way.

I have one of the first generation ductless and it heats my house down to -6 Celsius before I supplement.
They have come a long way since then.

I was wondering if the compressor unit were on the south side of the house, would a small greenhouse structure and some thermal mass inside capture some solar energy to drive up winter efficiency. Take it off in summer like old fashioned storm windows for AC, what would be the minimum air volume required?

I was thinking that in Canada the sun angle is so low in the winter that you could put solar panels on the southside of your house too, for when you needed power the most, in the dead of winter. They wouldn't even get snow on them and would be largely shaded in the summer. Solar panels are getting cheap and installing them on the side of a house should be cheaper than the roof. The sun might be shining in January, but the 6" of snow on yer roof solar isn't helping at all and neither is the low sun angle, but the ones on the southside of the house are doing just fine. Prices for solar panels continue to drop and as they get lower perhaps more people in the north will use near vertical ones in the winter attached to the south side of houses or buildings. They won't be needed or used much in the summer with long days and high sun angles. The falling price of panels might make this feasible.

A local gluten free flour mill uses the entire south facing wall for heating their facility. Works like a charm with only a tiny furnace used for office space.

My unit is on west side but south would be best, if possible. Placement of the variable capacity splits is pretty important as most seem to be quite noisy in colder temps, although ductless are amazingly quiet. Lots of air flow required or it will lower the air temp to low to be viable.

Looks like Lee is tracking ENE a little in this loop.......

keep and eye on him.....maybe that high in the area is pushing it that direction....we'll see....be careful out there

Went out and stocked up on candles and extra batteries just in case, this evening I'm gonna get some extra groceries and some cash. I think it will miss us, but the one last year depleted my emergency supply of candles and batteries for LED lights.

cool, good to hear, also stock up on water and canned goods just in case.....from it track this morning like i mentioned early it seems to move ENE, then again Lee will do whatever it wants to do.....so just keep an eye on it, and be safe ok.....

We can see them coming up here a long way off, but it's a roll of the dice where it will hit, even though it is greatly diminished, the trees up here still having leaves tend to bring down the power grid in places, or the entire province like last year.
