The climate change consensus extends beyond climate scientists

Where you dig what amounts to rust out of the ground, turn the rust into iron and add a little bit of carbon that stays with the iron while removing impurities.

Remelting steel and iron to recycle it using an electric arc furnace is common.

I just looked at smelting. It looks like you electrically heat the ore ,while adding a chemical reducing agent.

Yes, but what about sintering?

When I lived in California I was taught that negative numbers were impossible, but my bank account proved them wrong! In happier news, my credit card was recently negative! They owed me money!

I always joke about celebrating Columbus day by putting three boats in someone else's back yard. I am not sure how much of what I was taught as a kid (in California) about Columbus was true, either.

Then there was the teacher that taught us that oxygen was Oh, because you cannot run around just saying "O!"

Tell that to J.R.R. Tolkien--or Oprah.

I was taught Algebra in ninth grade, but never how to balance a checkbook, let alone whatever the modern equivalent is, because who uses checks?!

I was taught to cook, but not how to eat healthy, although I am not sure there is a consensus on that, and theories change constantly.

I had woodshop, but that was the only time that I ever had the proper tools for a project. Thanks for spending thousands of dollars on equipment that I would never use again. How do I do that with a circular saw, a hammer, and $6.10?

I had a metalworking class. Guess who has never worked with metal. I have hammered out dents, but that was not the metalworking that I was taught.

Changing a tire is easy enough that I figured it out when I was in high school, but how many people get stranded because they do not know they can do these things?

Who teaches kids to purchase new Chryslers and trade them in the next year? Who teaches kids to study whatever they want in college and then do something else?

Mom's mechanic just charged her $50 for an oil change and $20 for a $10 air filter. He is a great guy and the day that I cannot repair a car myself I will immediately take mine to him, but how many repairs and how much maintenance can you do with a $10 set of tools?

Am I trying to put mechanics out of work?

Do people learn basic life skills?

No, most people do not learn basic life skills anywhere, not alone school!

You'll be shocked how many people can't run their own finances without running debt to make up for chronic mismanagement.

So, apparently this genius invention was designed by someone who failed to adjust to life after prison:

I have so many questions! Why do they charge $80 for a small piece of cheap plastic?! They say it is one-size-fits-all, but why doesn't a single review claim it actually fit their tank?! Where did they find so many people intolerant of using warm water?!

So, you need to modify it to fit your toilet, but that voids your warranty! Brilliant!

From a three-star review; he hates it, but the wife loves it, so they compromised and kept it: "Your mission, should you choose to accept it, is to wash your hands under the tiny faucet before it shuts off."

Making fun of things is fun!

Here in Show Low it costs .289¢ per gallon and you could purchase 27,681.661 gallons of water for $80. If my toilet uses three gallons per flush, I would need to use it 9,227 times to break even. It does not specify how long the warranty is and surprisingly, nobody has asked. Someone asked about washing your hands with warm water and people acted like he or she was an idiot. Curiously, they insulted the person who asked the question, but referred to actual information: https://news.rutgers.edu/handwashing...germs/20170529

So, all of the weird kids that insist on washing with cold water were apparently right all along.

If hot water does not clean hands better than cold water, then how much energy is wasted by heating water used for washing hands and how much water is wasted warming it before you wash your hands?

I also found statistics that 18% of home energy use went to heating water. If you use a solar water heater, wouldn't you need a conventional water heater for nighttime use?

I kinda like the faucet on top of the toilet idea, but it would need to be implemented much better so you aren't straddling the throne and splashing water everywhere.

Rarely do I wash my hands with warm water; pretty much only when I've got lots of grease to remove from my hands. Since I finish the whole affair in just a few seconds, I'm not going to wait for hot water to arrive at the faucet.

Water here is billed at $0.00231 per gallon. Why people buy it in bottles when they don't live in 3rd world countries, I'll never know.

Electricitymap.org seems to have good real time electricity production data by source for California any time you want to look. The scroll bar between the map and the data is hard to grab but you can click on the left 1/4 of the screen and arrow up and down. Scroll down to see the 24 hour history and point at the the different colors to see percent of capacity and percent of total. And the time seems to display your local time regardless of which country you are looking at so you have to convert.
.
It is late in the cooling season and was Saturday so the week days may look different from more industry but California had a low of 18GW at 3:AM and a high of 25GW at 5:30. Solar peaked at 63% capacity factor and it was windy with the turbines showing over 45% CF all day. 1/3 of the peak was covered by gas and 1/3 was imported.

Germany's wind and solar are both doing 10% capacity factor today and less than 10% each of the total production with 48% of electricity coming from coal and 16% from nuclear.

I think the Sink Twice idea has merits, but it does not seem that it is worth eighty dollars, especially since the warranty is apparently one year. You would need to flush the toilet (and wash your hands) over twenty-five times a day just to break even. Yes, standing over the toilet to wash your hands would be weird, but I am not sure how else to do it. I was surprised to read how many homes have a bathroom too small for a sink. I have never seen one. I guess situations like that require this, but how common is that?

Well, they have sold four thousand of these devices. I wonder at what point they would sell enough for the price to come down. It may not make financial sense, but I imagine there are many situations where early adopters make good things possible for the rest of us.

What if you used a T to hook up water that would flow into your sink to a small unit on your countertop, which then ran into the toilet? Yes, this would require the countertop space, although perhaps you could design something to attach to the end of your counter, or the wall, and you would not need to stand over your toilet. You could also design something more closely resembling a sink and not an inverted toilet lid. I wondered how much extra water a design like that would use, but if you designed something with six feet of quarter-inch tubing, it would hold less than two ounces, based on the math used here: https://www.quora.com/How-much-liqui...-500-feet-long

If you used this enough to break even, you would use an extra 144 gallons.

A surprising number of people asked about brushing their teeth in this. Who brushes their teeth immediately after going to the bathroom, without washing their hands? You know what? I do not want to know, but they are concerned with brushing their teeth, but not about fecal hands?

Why would anyone do that if they had an actual sink? "I could use a normal sink like some weirdo, but I am going to bend over the toilet tank like a cool guy, flush the toilet, and now we are in business!"

The turtles feed in Cape Cod Bay in the warmer months but, when they fail to migrate south for winter, they get stuck in cold waters.

Once their body temperature gets down to about [50 freedom units, their metabolism begins to shut down.

Why didn’t you go home?! That’s your home! Are you too good for your home?! Answer me!
