Yes batteries have made it to 200K and even 300K if I remember correctly. You do have to be careful because in some cases the battery was replaced along the way. However, I believe there are cases where it wasn’t.

There’s a lot of nuance to this which Elon seems to miss. US immigration will blunt the issue here. China, Europe and Russia will see bigger issues with an aging population. Automation will blunt the problem. Considering Elon’s statements about where he sees robotics going, his stance on this...

History will show that there was a time when we could have cut carbon emissions while improving lifestyle at the same time. Instead we ignored all of the “inconvenient “ data until correcting things became a century+ long effort. Very sad. We have been at a stage where we didn’t need perfection...

I can understand winterization for the immediate future. Longer term, I wonder what you think about the analysis done by Tony Seba and RethinkX? https://tonyseba.com/wp-content/uploads/2020/11/RethinkingEnergy2020-2030-LRR.pdf

I see we have the same old comments about prior high CO2 levels. As before the key fact of reduced solar output is conveniently missing. The implication is always that scientist who spend their lives studying climate are somehow ignorant of this basic data or else members of a vast conspiracy...

I believe the Jeda hubs do and the have both A and C ports. I use the older Jeda hub. I like the hidden space for the SSD.

I have the Jeda v3 with the spacer installed but no lightning cables. My 12 Pro Max is in the Apple MagSafe case. It works fine both portrait and landscape. I seem to remember the documentation saying the spacer was needed to allow room for larger phones.

Interesting stuff. I didn’t look into Mr. Cool. I had a Carrier Greenspeed put in over the summer and a Rheem heat pump water heater. I had put in an induction cooktop earlier. It was nice having the gas company remove the meter. Unfortunately, I can’t put more solar on the house. The HOA is...

When I went to Mobile I stopped at Auburn. On the way back, however, I had a long stop in Greenville (Kim loves Crackerbarrel including browsing the store) and the car said to just go home (Alpharetta). I had just about 100% to start. I got home with about 14%. That was in a single motor long...

I think Tesla cares a lot about phantom braking. However, there is a reason that phantom braking is a problem on all cars with automatic emergency braking. The degree to which it is an issue depends on how much you want AEB to work in real cases. You can minimize phantom braking a lot if you are...

Thanks!!, it makes sense that heat pump only is the most efficient. However, the admonition to be more efficient by shifting to Energy Saver and the blue leaf icon for energy saver send a different message. I was wondering if it was a lower power heat pump mode. I have the 80 gallon model and...

I set my water heater to heat pump mode but the app keeps telling me to change it to Energy Saving mode for maximum efficiency. I would think that heat pump mode would be the most energy efficient. I find Rheem’s information confusing.

There was a time when the argument was that you were incentivizing technology development with the hope that someday it would be competitive. Now you EV incentives are incentivizing near term action that results in long term gains. I would love to see the elimination of the oil depletion...

Savings if 25% or 75% of cars were electric: Widespread electric vehicle adoption would save billions of dollars, thousands of lives: Study finds improved air quality would avoid health and climate damages

it seems to me Energy Saver should be named Hybrid. When I first shifted to Heat Pump the app admonished me to go back to Energy Saver. I went back to Heat Pump again and this time there was no warning. I’ll look over the next few days to see if it makes a difference.

I have the 80 gallon model and there are just two of us. We never run the tank more than a third down.

The manual is confusing. It lists efficiency for heat pump mode as high and for energy saver as very high. Hence manual says energy saver is more efficient.

When I saw the heating elements go on was when it was first turned on. Changing to energy saver (checked wording) turned them off. I don’t see a temperature readout other than the set point. I haven’t turned on scheduling yet. Does that make much difference?

Just remember that it also has large conventional heating elements. I was surprised to see them turn on in heat pump mode. You have to go to eco mode to make sure they don’t turn on. After two people taking showers last night it is fully recovered 7 hours later which is good enough for me...

Thanks for posting the certificate. At no time did the company say that if I paired this with that I would gain efficiency. I will say that the new system easily handles my house and never struggles. This is the hottest time of the year and it will only get easier once the attic is foamed. if...

Our rates are about the same. Electricity is around 9 to 10 cents per kWh. Gas is about 23 cents per therm. However, the gas base rate is over $32/month. I checked again yesterday and was overstating slightly but not much. I like the idea of no gas both from an environmental and a safety...

My heat pump water heater gets put in today. I wired the 30 amp line yesterday. Monday I get to tell the gas company to turn gas off at the street.

Be careful because the rebate is in the form of a credit that can only be used at their retail stores. The rebate can NOT be used at Menards.com. I can’t use the rebate. Fortunately I read the fine print.

I can find last years model but it isn’t available online and isn’t available within 100 miles. Oh well...I may break down soon. I am eager to tell the gas company to disconnect the house.

I know I'm late to this and I haven't read all of the posts but here goes. I will be putting an 80 galling Rheem in. I just wish I could find it on sale. $2200 is a lot and then there is installation. My current water heater is a 50 gallon gas unit. However, the first hour rating is 80 gallons...

That sounds about right. Expect about 1 mile per hour loss with Sentry mode on. In 23 hours that would be 23 miles or 37 kilometers. On a car with an EPA rating of 310 miles that would be 7.4%. Sentry mode keeps the ultrasonic sensors running along with the cameras.

Global warming has upended 6500 years of cooling Major new paleoclimatology study shows global warming has upended 6,500 years of cooling: Comprehensive compilation of pre-historic temperature records shows that global warming is reaching levels not seen for at least 6,000 years

Extreme warming of the South Pole Antarctica warming faster than planet in general.

Nah, I bet they prefer the strip mining the government supports. :)

The trip footage is recorded as before. A current limitation of the viewer is that it only shows footage saved to special folders either from Sentry events or from a user directed permanent save (honk or select save from icon). I pulled my drive because I too was worried. The trip footage was...

They have this “my way or the highway” attitude without even clearly stating what their way is. OK so we throw out growth and we depopulate (euphemism for kills billion or so people), How far do we depopulate? You don’t like solar and you don’t like wind so I guess we have no electricity. For...

Moore cites the pandemic as a shining example. Yes, if we starve people we can speed up helping the environment. Yes, if people can’t pay rent and mortgages then we will help the climate. I’m waiting for Moore et. al. to walk the walk. Stop using transportation. Stop using electricity. Show me...

Yep, looks like I was wrong.

To give you a serious answer, it means Tesla is fixing bugs. However, there is always the danger that a fix breaks something else. Complex real time software is difficult to test. 12.10 was a bug fix but without stopping at stop signs and traffic lights. 12.6 enabled stopping at lights and stop...

I may upset some people but while watching this I felt like I was watching the environmentalist version of Fox News. Let me see... natural gas is a fossil fuel so it is as bad as coal. I’m not a fan of natural gas but it is not as bad as coal. Solar and wind require fossil fuel backup so don’t...

I disagree. You don’t have to turn it on. If you do, it defaults to stopping which will definitely keep you engaged. Each time the driver tells the car to proceed, Tesla can compare to what the car saw. In most cases this will be verification that the light was indeed green. However, if there is...

Nice article on CBS News about 10 climate change myths: 10 common myths about climate change — and what science really says

From Tesla Roswell, GA:

JP Morgan economists warn of climate 'catastrophe' "It could put stresses on water, cause famine, and cause people to be displaced or migrate. Climate change could also cause political stress, conflict, and it could hit biodiversity and species survival, the report warned."

What many suspected. Revealed: quarter of all tweets about climate crisis produced by bots

The military view of climate change. Military perspective on climate change could bridge the gap

Climate change models predicted ocean currents would speed up — but not this soon Ocean currents increasing faster than expected.

I want to second the idea of watching Tony Seba. He has been a bit wrong. I have been watching him for several years and he has been off a little bit but overall pretty close. However, I guess I have a different take than Swampgator. Based on what Seba says, coal and even natural gas are lost...

Milankovitch cycles occurred during the past 800,000 years and are taken into account. They are actually a driver of some of the CO2 variation due to changing ocean temperatures. This is why CO2 lags. CO2 is not the driver of the variations over the past 800,000 years but it does set the center...

2 degrees will cause a massive economic disruption and it will cost way more than fighting the increase. Massive dislocations of people, the loss of coastal cities and major political issues. Our military is very worried about global warming and it isn't because of some do-gooder mentality...

Perhaps; but it is a good period over which to see what we have evolved to live in. The climate over that period was generally colder than now. Even if you go back 600,000 years you will see that CO2 levels for that entire period were lower than today. Getting mean global temperatures over that...

You bring up something that annoys me with environmentalists. They say we are destroying the planet. I think the planet will be just fine. Homo Sapiens not so much. If you want to talk about temperature range keep it real. No point in mentioning that the planet was once molten on its surface...

Emissions of potent greenhouse gas have grown, contradicting reports of huge reductions Emissions of potent greenhouse gas have grown, contradicting reports of huge reductions Not good.

A note about how the egos in big science really work. These were the bright kids in high school. They were the smartest people they had known until one day they looked around and they were scientists where the people around them were just as smart. They LOVE showing that they are right and...

She is wrong because of her age. She is wrong because she is diagnosed as autistic. Nothing about the facts of what she says. I see little difference compared to the high school bully calling the small kid runt or the heavy kid fatso. By the way, most people are somewhere on the autism spectrum.
