Climate in the 21st Century

[DIY-HP-LED]

lets see where is goes, might be a little early for assumptions

Oh, I'll be keeping a weather eye on it, but so will others and if it gets close or looks like it will be there will be a run on such things. I'll make the call on preparedness later, after we find out a bit more, but I might hedge my bets a bit. Last year we lost power in the whole province for days and some places weeks, nothing worked, no gas or groceries, just thousands in the dark, the cell service even went down for a spell and so did the internet. I was charging devices from my car and listening to tunes and the radio for news in the driveway for a week. Big trees were down all over the place in town and still full of leaves.

i've been through a few myself, and i even helped with clean up with one, so i know the devestation it leaves....

I'll be stocking up on candles, batteries, gas and canned goods and keeping an eye on it. I got a propane gas stove and know how to make one of these if required! Burns twigs that you cut up with some gardern shears and keep in paper bags and can cook yer food and make yer coffee when the propane runs out. A DIY wood gas stove made from tin cans, just the thing for extended power outages and the local propane runs out, you can gather twigs anywhere except in the desert and even there...

A useful video to watch, once you know how, you can build one, too late when the power goes out, but YouTube is on your phone, but the cell service might be down too.

Them liberals want to take a man's God given right to make fire!

Air heat pumps can output 3 watts of heat for every watt of power they consume and ones that use buried loops and ground heat below the frost line produce 5 watts of heat for every watt of power they consume. Gas for residential use is being phased out or will be and traditional resistive heating produces one watt of heat for every watt of power consumed. If the goal is solar self-sufficiency with a home battery and solar panels on the roof, then using a heat pump for heating and cooling while storing excess energy generated in the hot water heater, battery bank and even plugged in EV should do the job with little or no input from the grid, while also powering an efficient small EV. Gas, oil and coal for home heating and cooking will be a thing of the past soon enough, some will use wood, but that is considered carbon neutral and doesn't use fossilized carbon. NG will still be used by industry and for emergency power generation though, but not piped into individual homes.

If most of the homes in suburbs surrounding a typical city were making their own solar power from roof tops, storing some of it for peak load periods and even supplying excess to the grid, how much outside power would the city need with miles of suburbs and industrial parks around it and most rooftops generating power? Maybe not with the chunky solar panels we how now, but with efficient PV built right into roofing shingles and traditional looking tiles, they are selling such products now and, in a decade, only utilities might use solar panels, domestic consumers will use products made for them.

Outside on the deck only or on a balcony, you would be surprised what some people will do for a hot cup of coffee!

It’s going to pulverize Florida. They just don’t want to scare the living shit out of anyone right now. My brother was all like, I live in the east coast of florida and we don’t get hit as much as the gulf . Oh, but when you do say goodbye to your house. Your hurricane shutters ain’t gonna do shit, bro.

Imo it won't get close, then again I have been wrong. Keep an eye on it...

Big waves and rip on the east coast will be the most of it. Canada might get a hit, but it will be cut down to size by then. Lots of shear ahead for this one. They predict it will only stay at cat 5 less than a day.

Never mind. The last update says it will go back and forth between 4 and 5 for the next few days. It got to a cat five quicker than anyone thought it would.

Extreme rainfall in Hong Kong, Brazil and Greece leaves dozens dead after flash flooding (yahoo.com)

Prime Minister Kyriakos Mitsotakis of Greece attributes the disasters to rising global temperatures.

“I am afraid that the careless summers, as we knew them ... will cease to exist, and from now on the coming summers are likely to be ever more difficult,”

I think he is right.

At least we have the memories.

This is with traditional Li-on cells, customized a bit, but there will soon be battery packs with double the energy density, the same power weighing half as much. New efficient flexible solar panels will help too, but if a design similar to this can get in the 10 miles per kilowatt hour range and with half the weight in battery that would be easier, it should cover the commuting needs of the average driver and could be recharged overnight to a range over 100 miles on a 120-volt internal charger.

The cheaper Chinese designs might look more like a conventional compact car, but 40 miles of solar range a day equals free transportation for the average American commuter and a small solar array on the garage and a cheap sodium battery bank could charge the thing up to 100 miles or more a day easy. Free transportation energy, the low EV maintenance costs and potential long life would be a big draw for most people. Even if you paid 20 cents a kilowatt how much would you use to top up such and EV for any kind of reasonable commute. Paying through the nose for power @20 cents a kWh and charging to 120 miles range on 120volts at home over night would cost about $2.40 for 120 miles of range, plus another 40 from the sun. Few people drive an hour to work and most probably drive 30 or 40 minutes or miles. Expect that next generation of batteries to be more power dense and have much better cold weather performance.

If solar power can give 40 miles a day with a vehicle getting 10 miles per kWh, then better solar panels and much lighter batteries will expand the range of vehicles that can do this to larger more conventional designs. I can see such cheap EVs doing very well globally, not just in America and the government should give the largest subsidies to them and none to kilowatt guzzling half tons or big SUVs. Maybe not so much in America, but EU countries would not have to import much gas or have to use much grid power if the majority of vehicles on the road were like that and could charge themselves with solar for the average daily commute. Think how resilient the population would be in the event of a grid failure or other national emergency, transportation for most would be largely unaffected, inflation would have a less impact and it might cause a drop in power rates because of reduced demand.

Who has 0.5 kWh/kg batteries in advanced development? Iirc the best Li-ion energy density so far is 240+ Wh/ kg.

I think we should see either lithium silicon or lithium Sulphur chemistries in 5 years and there are other pouch pack designs that are lighter and are more power dense than these steel cased cells. I'm talking about a future class of vehicles that would get similar range to the Aptura, but look more conventional because of improvements to battery and solar panel technology, we are in a rapidly evolving technological situation with enormous market financial and government incentives. I've posted enough startups, large companies and breakthroughs in battery technology and chemistries, the battery factories are springing up like mushrooms and not all of them are producing conventional Li-on cells.

My point is, if such a class of vehicles could be produced cheaply, they should sell very well globally and we appear on the cusp of major battery improvements hitting the road soon, reduced costs through mass production for sure. I think with the activity we are seeing in R&D and in factory construction the battery landscape should be much different in 5 years with many more options and much lower prices. I think they are over building, like they did with solar panel production in China causing a price crash and now it is coupled with other countries in the EU and America producing panels again using a lot of automation.

If we truly are to see them on the market in 5 years, they should be in advanced development, with the design intended for manufacture essentially finalized. There’s a fair amount of testing (safety, operating envelope, charging characteristics, number of cycles* before capacity drops to 90% initial, manufacturability and upstream supply definition etc.) that’ll need those five years.

Otherwise I’d say you’re being unduly optimistic about the timeline.

*There will be two numbers: one for slow home charging, and one for routinely getting punched in the face by megawatt chargers on the road.
