Plenty of federal facilities have garbage reception. I think it’s probably due to the bureaucracy involved in telecoms installing their hardware on sensitive property. The White House in particular probably has lots of thick walls/armor attenuating signals, too.
⁨Comment⁩ on ⁨No, renewables don't need expensive backup power on today's grids⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:
The story here doesn’t really seem to line up. Generally, for a fossil fuel based system, coal is cheap, but slow to start (nuclear is similar in that regard), so it is used to generate the base level of electricity needed. When demand starts to go up, generation is added by natural gas plants that can start and stop more easily. Whether natural gas is cheap or not, the fact that these plants aren’t always on means that the energy they produce will cost more.

Solar/wind are predictable enough that they can be used to reduce the baseline demand, supplied by coal. Peak demands still end up getting addressed by natural gas.

If renewables were putting the expensive natural gas generation out of business, we’d see those plants closing while coal stays level, but we see coal going down and natural gas going up.

Using the Texas example from the article, you can see their coal plants closing or converting to gas while more gas plants open. …wikipedia.org/…/List_of_power_stations_in_Texas

Yeah, I want one of those, too. I think it fits different needs, though. Stove vs grill.

I think there are some municipalities with that in code, but it’s definitely not universal in the US.

I live in a house with a gas stove that vents into my kitchen.

I definitely hear you about the coffee roasting. I assumed when they said that it smokes that it would just be like thin wisps, and I definitely smoked out my house. I’m not going to do it inside again.
⁨Comment⁩ on ⁨YSK: Gas stoves cause cancer⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:
For a lot of these large scale, epidemiological findings, it’s important to remember that the effects are small enough that you pick them up on a population level over a lifetime. I’d say that if you can, find a way to properly vent your stove outside if you are doing some home improvement. If you are replacing your stove, consider induction instead, and in the meantime, having an air purifier is good. Opening a window is probably also good. Other than that, I wouldn’t be super alarmed. Obviously, if you have little kids or something, you might have a lower tolerance for potential pollution, but it’s good to think about these things in context. Alcohol causes cancer, but everyone still drinks.
⁨Comment⁩ on ⁨YSK: Gas stoves cause cancer⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:
I think the people who claim gas stoves are best likely grew up either not cooking much, or had a decent gas stove, so their first exposure to an electric stove was super cheap, crappy electric coil stoves in student housing, or wherever they first lived as a young adult. Then when they were able to afford better, they got a better gas stove.

I have a really crappy gas stove, and it makes me yearn for the cheap electric coil stoves of my youth.

People say that gas stoves are more powerful and responsive, when the truth is that more powerful stoves are more powerful, and “responsiveness” is a fake concern. My crappy gas stove takes forever to get a pot of water boiling, especially compared to coil stoves. Yeah, you can turn a gas stove to 100% quickly, but that’s only better if it can put out more power. It won’t heat up any faster than an electric stove if the electric stove takes double the time, but also has double the power. There’s also not many cases where “time to maximum heat” is what you care about, I can’t think of any.

Responsiveness the other way (hot to cool) doesn’t matter when you have a high thermal mass in the pan (or the pan itself has high mass), it only matters when the pan and contents are light, in which case, you just take the pan off the heat.

I’ve never seen a gas stove with temp control. I’m not even sure how that would work. Controlling the amount of gas, sure, but not the temperature. In an induction stove, you can set it to 150 degrees, and it will hold that.
⁨Comment⁩ on ⁨YSK: Gas stoves cause cancer⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:
Or they have a fan that just redirects the exhaust into the house
⁨Comment⁩ on ⁨YSK: Gas stoves cause cancer⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:
A $50 dual burner camp stove solves that (or even cheaper, a $12 single burner backpacking stove if you have less space).
⁨Comment⁩ on ⁨YSK: Gas stoves cause cancer⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:
Never seen something like this?

It’s a pain in the butt cause all it does is suck up any smoke and direct it towards your smoke detector.
⁨Comment⁩ on ⁨YSK: Gas stoves cause cancer⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:
Yeah, a coleman (or equivalent) 2 burner camp stove combined with the adapter to use a full size propane tank is super handy. Combine it with a cast iron griddle, and you can functionally replicate a Blackstone for much much cheaper. It’s also way better for high heat cooking if you don’t have a good stove fan that actually vents outside.

Also, sometimes when power goes out, gas does too (it’s still a grid that can fail).

⁨Comment⁩ on ⁨Wall oven selection⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:
Not to try to oversell you or anything, but I wouldn’t write out ovens that have convection capability (often marketed these days as airfry). They cook faster, with more even temperature, and it’s literally just a fan to blow air around. It shouldn’t really have much effect on the price. I think it should theoretically make the temperature oscillation much lower, too. Personally, my dumb oven swings by like plus and minus 50 degrees F with a 25 degree offset. So if I want 350, it will bounce from 275 to 375. Newer, smarter ovens can have better control methods to maintain temp.

If your current oven heating element melted itself, I would suspect that there’s something wrong with the thermostat, so there may be additional parts that need replacing.

⁨Comment⁩ on ⁨US bans controversial red food dye, decades after scientists raised alarm⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
All the concern about this dye is based on a 1990 study where they fed rats 0.5%, 1%, or 4% of their diet by mass with the dye. Only the group with 4% of their diet had an effect on thyroid stimulating hormone, and follow on effects on t3 and t4. This increased stimulation of the thyroid is what they hypothesized is responsible for potential tumor growth. That dose is ~5,000-15,000 times higher than a regular diet. Increasing sugar or alcohol or literally anything else in your diet by that amount will have dire consequences.

Furthermore, the authors mention that a 100x dose human trial had increased TSH, but without changes to t3 or t4. This (and other factors they bring up in the paper) show that humans don’t respond like rats, so these rat studies can’t really be applied to humans. Even a massive overdose wouldn’t have the same potential for causing cancer in human as it does in rats.

All that said, there’s no benefits to the consumer to have food that’s just more red. Banning red 3 isn’t going to make manufacturers stop dyeing food red, it’s going to make them switch dyes, which might not be able net positive.

The FDA’s notice even says this:

two studies that showed cancer in laboratory male rats exposed to high levels of FD&C Red No. 3 due to a rat specific hormonal mechanism. The way that FD&C Red No. 3 causes cancer in male rats does not occur in humans. Relevant exposure levels to FD&C Red No. 3 for humans are typically much lower than those that cause the effects shown in male rats. Studies in other animals and in humans did not show these effects; claims that the use of FD&C Red No. 3 in food and in ingested drugs puts people at risk are not supported by the available scientific information.

They mention that they are forced to ban it due to a technicality of the law:

The Delaney Clause, enacted in 1960 as part of the Color Additives Amendment to the FD&C Act, prohibits FDA authorization of a food additive or color additive if it has been found to induce cancer in humans or animals.

So even if we know for sure that a substance is fine for humans, if there’s any animal that could be given cancer by ingestion of any dose, it legally should be banned.

For example, if you did a study where you fed dogs chocolate for a year, and they developed liver cancer due to the constant poisoning, you could petition to have chocolate banned as a food edditive.

⁨Comment⁩ on ⁨Breezeway Greenhouse Help?⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:
My dream is to one day have a setup like this. Like others said, humidity and heat in a greenhouse are 2 big concerns. They make all kinds of automated systems for opening vents, etc.

If your primary goal is growing in a contained area to keep pests away (vs. needing to really keep the space warm in winter or something), you best bet could be a hoop house. Basically you can drive rebar or fence posts into the ground, and then arch something (pvc pipes commonly) from one side of the space to the other. You’d then pull plastic sheathing overtop. Those are commonly used to get growing started in early spring and extend growing in the fall. When it’s warm enough, they basically roll up the material. You could do something similar but still have a structure of chicken wire or netting or something to keep animals away.

If you actually want to keep the space warm to grow in the winter, you might want more permanent walls with better insulation, like double walled polycarbonate.

Another thing to consider is water. If you have a greenhouse next to your house, you don’t want rain that falls on it to direct water to your house’s foundation.

Searching around, it seems like stucco and high humidity may not work well together. Personally, I’d be a little concerned about algae/moss growth on my walls if I had high humidity on stucco.
⁨Comment⁩ on ⁨Breezeway Greenhouse Help?⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:
I love the look of repurposed windows/doors for greenhouses, and I’ve even seen them advertised for that purpose at resale shops, but it’s really important to be careful about lead paint if you want to do that. Lead was the primary white pigment for a long time, and since windows/doors are often trimmed white, if they are older than 1978 (in the US, EU was 2003, though many member states had their own laws previously), it could be lead. Lead testers are fairly cheap if you want to go this route.

This is the lab behind the poop knife. They are absolutely experts in this kind of thing.

I need to read the whole paper, but I suspect the weight/wind resistance ratio of the javelin is better, and that the motion of launching an atlatl dart is affected by the downward angle. The railing on the scissor lift likely has an effect, too.

⁨Comment⁩ on ⁨Vertical solar panels help farmers produce both energy and crops⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:
It’s not a very long article, so they don’t get too into detail. This would use bifacial solar panels. On a purely optics standpoint, you’d think they are much worse than traditional (i.e., facing south at the right angle) panels, but they gain efficiency by staying cooler, and they generate more power when traditional solar isn’t, which helps smooth out the power generation curve. They also self clean and don’t have as much hail risk.
⁨Comment⁩ on ⁨Problem?⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:
Yeah, reviewing is about making sure the methods are sound and the conclusions are supported by the data. Whether or not the data are correct is largely something that the reviewer cannot determine.

If a machine spits out a reading of 5.3, but the paper says 6.2, the reviewer can’t catch that. If numbers are too perfect, you might be suspicious of it, but it’s really not your job to go all forensic accountant on the data.
