Climate in the 21st Century

A lot depends on where you live and what the average temperature is, summer and winter, if near the coast with the moderating effects of the sea, just air exchange heat pumps might do, near the center of the continent temperatures are more extreme in the summer and winter.


Is a Geothermal Heat Pump Worth It? My Net Zero Home

Is a Geothermal Heat Pump Worth It? My Net Zero Home. Heat pumps are the most efficient way to heat and cool a home, but they’re not all created equal. Geothermal, or ground source, heat pumps are more efficient and effective at a wider range of temperatures than air source, but at a cost. It’s way more expensive up front, but that should even out over time…at least in theory. I’m going to be the guinea pig for everyone out there because we went with a geothermal system for our new home. What does the setup look like? What do the costs look like? And in the end … is it going to be worth it?

We are not quite there yet with batteries for heavy trucks, but the proliferation of light vehicles as EV will drive battery costs down and increase the variety and capacity. The battery factories are being built now and most are making different kinds of batteries than the traditional Li-ion cells. It is a question of commercial operators taking advantage of battery improvements and mass production. Local delivery heavy trucks must last a shift or the day and be charged at lunch and operate in all weather conditions.

Above all else, electric trucks have to make economic sense for business owners and offer an advantage over ICE powered ones. In that market there should emerge two types, with the local delivery varieties appearing first, those that are parked at night and can be recharged overnight for the next working day. Long range trucks might use pantographs like trollies and trains to recharge on the move and only about 25% of main routes would need to be served with overhead charging wires over the righthand lane, batteries do the rest. Such trucks can be automated and there is already a shortage of long-haul truck drivers, they might be uncrewed on the highway and pick up a local driver on the edge of a city, like a ship's pilot at a harbor.

I think we will see Perovskites emerge as a big player in the solar market over the next decade. A lot of problems have been solved or are well on their way to being solved, to produce cheap efficient solar panels and even more expensive high efficiency tandem cells. There should be cheap flexible efficient panels with long lives too. They are making the first ones commercially starting in the next year or two, but the next decade should see them competing with silicon solar and driving the cost of solar energy even lower while increasing its flexibility. They should be arriving on the scene in a few years along with a few different types of batteries some of them mass produced for EVs and energy storage for the grid and home.

For people and businesses to go green it has to make economic sense and offer advantages, it must be affordable by the masses and small businesses. If you are gonna put solar on your roof and a battery bank in your basement along with a new water heater it has got to be cheaper than grid power. Excess can be sold to the grid to offset any usage and the system can be programmed to store and sell energy to the grid. Even offsetting grid costs for most of the year might be enough to make sense, because transportation as well as home energy are involved. Now a lot of people pay for grid power, but they also pay a monthly gas bill for heating and a gasoline bill for their transportation, so the total costs must be considered.

Solar is already the cheapest form of electricity generation by a bit, and it is continuing to get cheaper still, perovskite solar panels would drive those costs even lower. This makes the mass manufacture of cheap good batteries imperative since the problem with solar is it doesn't work at night and the wind doesn't always blow for the turbines. Cheap batteries make widespread energy generation and prosumers possible as people with single family houses can be energy independent or pay a minimum fee, or nothing to the grid for their domestic and transportation energy.


Top 5 Solar Energy Advances Using Perovskites

Top 5 Solar Energy Advances Using Perovskites. For years, perovskite solar cells have promised revolutionary improvements compared to traditional silicon solar panels. Perovskite could hold the key to higher efficiency at lower costs and in some cases has shown a 250% performance boost. But scientists have been working on improving this solar energy tech since the 1990s. What do we have to show for it today? This feels like yet another piece of over-hyped, planet-saving tech, perpetually 10 years away from adoption, right? Maybe not … they might finally be on the market before the end of this year. Let’s look at 5 perovskite solar panel advances since the last time we talked about it.

The fatal problem with evs is cold temperatures. I would much rather have an ICE engine to provide me with hours of warmth when I get stuck in a blizzard or some other cold condition where my car is stuck... do you honestly expect evs to be able to keep you alive in such a situation...no if your smart you don't.

I believe considerable effort is being pointed at that problem.

We’re on battery chemistry 2.0 here, with lead-acid being 1.x.

I fully expect batteries that will work in winter in ten years.

Imo not nearly a problem.

“too late to avert the deaths of millions” probably. But not billions. The species will make it.

Sorry I was being over dramatic...of course their will be the few that survive. Einstein said we'll use rocks on the otherside

I’m not inclined at this time to be quite so pessimistic.

I imagine technology at least to about 1950 will be in play.

Now I like this thread.

Maybe I just missed the output first ..idk but often these links are missing a proper formatting/introduction from one who shares it. It's tedious to spent hours for minutes

And it would suck if the ICE (you do not have to add engine afterwards, that is what the 'E' is for) would be out of gas. But you say, "I prepared and had a full tank of gas." Well, as with any thing you need to think ahead. Why would you not think ahead with an EV? I do not think EV's are all that practical in my neck of the woods, long distances and a lot of nothing in between. Also some frigid temperatures in a large part of the year.

This would make solar powered compact cars feasible or close to it, with a significant portion of their daily range requirements coming from solar panels on the EV. Much of the weight of an EV, even a compact one comes from the battery and the lighter the car the further it will go on a kWh of energy. If you drove more than average, you might have to charge your car at home from 120 or 220 volts once a week. High power density batteries will be used for mobile applications, lighter vehicles make more efficient vehicles.


This is where our innovative materials technology, Lyten 3D Graphene, comes in. We are tuning the material to deliver two capabilities for batteries. First, we are designing the material to act like a scaffolding for the sulfur, essentially holding the sulfur atoms in place inside the battery so they don’t move freely, an effect called polysulfide shuttling. Second, the Lyten 3D Graphene is electrically conductive, helping the energy move in and out of the sulfur and within the cathode more efficiently. With these enhancements, we are producing Lithium-Sulfur batteries from our pilot line today in San Jose, CA.

The implications are significant. We are now targeting a battery that has greater than twice the energy density of lithium-ion and will be more than 40% lighter weight. Additionally, we can remove many of the mined minerals found in lithium-ion. Lithium-Sulfur will not require nickel, cobalt, manganese, or graphite, all heavily mined minerals in short supply and with their own environmental and humanitarian impact. This dramatically simplifies the materials required and will ultimately allow the lithium-sulfur battery to be entirely sourced and manufactured domestically in the US and Europe. Adding all this together means a battery that will have 60% lower carbon footprint to manufacture compared to lithium-ion today and a clear pathway to an even lower footprint in the future.

We describe Lithium-Sulfur as the “electrify everything” battery, as it will break through price and weight barriers, enabling electrification to be far more viable for both industries where weight matters (aviation, aerospace, trucking, etc) and mass market adoption where price is a barrier. There are many new chemistries in development, but the majority of those chemistries present lower energy density than lithium-ion. They tend to solve issues like materials, supply chain, and cost, but not higher energy density required for mobility applications. The chemistry most commonly discussed for higher energy density are solid-state batteries, which will certainly have their place in the value chain in the future.

Lithium-Sulfur advantages versus solid state are that (1) Lithium-Sulfur are being designed to achieve higher energy densities, so they are lighter weight, (2) Solid State is still highly dependent on minerals like nickel and have a complex supply chain, and (3) we believe Lithium-Sulfur will more easily drop into existing lithium-ion manufacturing lines with only minor modifications.

This is pretty wild.

Same shit here and barely any chargers anywhere. None at all in the small town 10 miles away and we average -20C all 6 months of winter. Already hitting 0C at night here. With power at 35¢/kwh or more it's probably cheaper to drive my gas guzzling 6cyl SUV. Biggest 6 they made back in '08.

Can't afford an EV anyhow so it's rather moot.

“This is not a fancy weather statistic,” Imperial College of London climate scientist Friederike Otto said in an email. “It’s a death sentence for people and ecosystems. It destroys assets, infrastructure, harvest.”

Do you believe in a God/spirit/rock?

Next time you pray ask it why it's going to kill all of us.

I'm just curious & when you hear back pm me..

I'll be waiting
