Average fuel costs are from the Energy Information Administration. Electricity is at: https://www.eia.gov/electricity/monthly/epm_table_grapher.php?t=table_5_06_a

Natural gas is at: https://www.eia.gov/dnav/ng/ng_pri_sum_a_EPG0_PRS_DMcf_m.htm

Costs are the most recent available, which is July, 2026 in most cases. Six states did not have a July price for natural gas and an earlier month was used. No gas price information was available for Florida so it is NA.

Heat pump performance is for a Mitsubishi P-Series Hyperheat with a nominal capacity of 54,000 BTU/hr, in a house with a design heating load of 40,000 BTU/hr at 22F, following the methodology for predicting heat pump performance in this article:

https://www.greenbuildingadvisor.com/question/how-to-model-and-predict-electricity-usage-for-a-heat-pump

I was inspired to do this after hearing one more person confidently state that "gas is more efficient than a heat pump at <temperature I just pulled out of my ass>." No, it's complicated. It depends on the local price of gas and electricity, and also the choice of equipment and the heating load of the particular house.

Prices vary a lot by state. Electricity prices range from 12.72c/kWh to 48c/kWh. Gas prices range from $12.38/MCF to $65.72/MCF.

The nationwide average price of gas in July was $26.45/MCF, in February it was $14.95

Pixel 10a -- can't connect to Bluetooth devices

I recently replaced my old Pixel 8 with a 10a. I have a couple inwall Bluetooth amplifiers in my house and I can't get the 10a to pair with them. They show up when I click on pair new device, but when I tap on them I just get "Pairing..." for a few minutes and then nothing happens.

I could pair to these devices with my old phone, and I can still pair to them with my Samsung.

I have upgraded to the latest system software.

I've restarted the phone many times, and tried stopping and starting Bluetooth. I've turned the Bluetooth devices on and off many times.

Is there anything else to try?

Where is the front radar sensor?

Every time I start I get a message that the front radar sensor is blocked. I'd like to check it, but I've been unable to find out where it is.

Changing automatic transmission fluid, 2000 Carry

I have a 2000 Carry with an automatic transmission. I've been unable to learn anything about it, like what the transmission model number is.

I want to do a fluid change. Usually this entails popping off the bottom case and changing the filter inside, but to do that I'd need a new gasket and a new filter. Any leads on where I could find such a thing?

Any other tips?

Thanks.

Controlling an AC motor with a dimmer

I have a small AC air handler that has a motor in it that is labeled 220V, 0.2A, 20W. It has four speeds, and four wires going into it that are controlled by relays. The motor says "YDK-20-4Z" and Googling tells me that's an induction motor.

My issue is that I find the lowest speed noisy, so I'd like to slow it down even further. What I'd like to try is using a dimmer module, something like this:

https://www.aliexpress.us/item/2251832615710334.html

Questions:

  1. Will this work?

  2. Could it damage the motor?

  3. Since the motor has four speeds, should I put it on the lowest speed and dim it, or put it on the highest speed and dim it?

  4. Assuming this works, why do manufacturers bother with multispeed motors and relays? The module I linked to above is 99 cents.

Thanks for any help you can give.

New spark plugs + new air filter + full tank= vroom!

My truck had been getting sluggish, particularly noticeable starting from a stop and going up hills. This week I replaced the spark plugs and air filter. I've also noticed that it runs rough when the tank is almost empty. What a difference when everything is right!

Kash Patel failed to disclose MSTR purchases

This could be the most 2026 story yet:

https://www.notus.org/money/kash-patel-stock-act

Patel, who has regularly traded individual stocks since becoming FBI director, purchased between $100,001 and $250,000 worth of stock in MicroStrategy on Nov. 21. But Patel did not disclose the trade with federal regulators until May 26 because he “inadvertently omitted” it from a previously filed stock disclosure document, he told Office of Government Ethics officials in a letter that day.

Moving 16' fence panels

Using my bed extender on the bumper hitch. The panels are floppy so I put a 2x6 under everything to stiffen it up.

I wouldn't recommend for highway driving, but these things are a pain to move any other way.

EK50 default piano sound

Maybe this is a silly question, but I'm baffled.

When my EK50 boots up, it starts on a grand piano sound. If I switch to a different sound and then go back to grand piano, it sounds different -- less full. As far as I can tell the only way to get the startup sound back is to power on and off.

Thoughts?

The Manhattan Project

I often hear people saying that what's happening with AI right now is like the Manhattan Project. There is a superficial similarity, with a lot of money being spent in a hurry in a technological race (although AI has already consumed 30 times as much money, even adjusted for inflation).

But the comparison misses a fundamental point: in the Manhattan Project, they knew what they were doing. The theoretical basis had been established experimentally in the 1930's, by 1942 the problem had been reduced to a materials science and engineering exercise. Over 80% of the cost of the project was the cost of acquiring and purifying the fissile material, once they had enough to reach critical mass actually building the bomb was almost an afterthought.

There doesn't seem to be any such clarity in the race for AI.

Vacuum and flush?

Looking into doing a DIY install. It seems the biggest challenge is getting the air and moisture out of the lineset. The two ways seem to be vacuuming and using a flushing fluid. Vacuuming is what the pros do, but the pumps available to DIYers don't seem capable of pulling as complete a vacuum.

Has anyone every tried filling the lineset with flushing fluid and then vacuuming it out? It seems you could get a more complete evacuation than with either technique alone.

Thanks.

P4 Tow eyelet thread pitch?

I just got a ticket for not displaying a front license plate. I didn't install it because the bracket that came with the car seemed so cheap. So now I'm looking at aftermarket brackets, and I haven't found anyone who makes one for the P4.

One option would be a bracket that goes into the tow hook slot, but I haven't found anyone who makes one of those specific for the P4 either.

Does anyone know what the thread pitch is on the tow eyelet? It looks bigger than earlier Polestars.

Thanks.

There seem to be more and more people writing about how AI is a bubble. Usually when a bubble bursts there is one precipitating event that triggers it, and OpenAI is widely viewed as the financially weakest player in the AI business. Ed has written extensively about how OpenAI just has no path to being a viable business.

So what is the event -- or sequence of events -- that pushes the OpenAI domino over?

I've been shopping for a robot mower and I have thick grass. Like my land used to be a sod farm, grass grows like crazy. What's been frustrating is trying to get a feeling for what mowers will actually work like on thick grass. Pretty much all of the videos I've seen just show grass that is so thin I wonder why they even bother mowing it.

But this video: https://www.youtube.com/watch?v=4KZfS3uFYu4 shows real, thick grass.

He also talks about how he takes pieces off to make the discharge chute as wide as it can be, something I always do with my mowers.

I'm looking to buy a robot and I'm worried that my land is just too rugged. I have swing blades on my rider mower. I just learned that Lymow offers swing blades, which has me thinking that's the direction I should be looking.

Does anyone have experience with them?

Thanks.
