    Reducing pollution is contributing to global warming?

    Perfection is the enemy of good enough. Gravity is real. If you don't like it as a geodesic in space-time, you are welcome to come up with your own explanation, but relativity explains it so well that it has never failed an experimental test. Anthropogenic global warming was predicted a...

    I think you should call it a footfeed. That's a century-old term that suits very well. Push it and it feeds the motor, let up and it feeds the battery.

    Understand that I was a really little kid, but it was a real truck with a long flatbed and a grain box that would haul several tons of wheat. I remember that the firewall was mostly a euphemism that let engine heat into the cab, and Dad didn't want us to crank the windshield out because he...

    That paper cherry picks its data in an effort to discredit it. Fortunately for those of us who respect reality, NOAA and NASA have satellite data that is not subject to local variations. https://climate.nasa.gov/nasa_science/data/ I have no idea why the denialists are so dedicated to denying...

    Sitting next to the Cascadia Subduction Fault, I can tell you that 1000 year events leave plenty of traces that can be analyzed and dated. Thinking you have to shuffle through old newspapers for records is nonsense. The Earth speaks.

    There was a dash throttle on my dad's '50 Chev pickup, and one on the Model A truck he started farming with. They made it easy to drive across a plowed field because holding a constant speed was automatic. I tried the cruise control on a Jeep to do the same thing once, but it did not work. I...

    Aren't manual and foot mutually contradictory? It's just a foot controller. Speaking of manual, one thing I miss off road is the dash throttle that would let you set a steady engine RPM.

    Religion aside, denialism is a classic case of not getting the message. How many 1000 year storms per year will it take to change your mind? I doubt it will ever happen. As long as you stay in the shallow end, you should be fine.

    The reasonable thing to do if you challenge one nation's conclusions is to look for others. http://www.climatecost.cc/images/Policy_brief_1_Projections_05_lowres.pdf

    Cocaine is a wonderful topical anesthetic. I had an eye injury when I was 20, and was in such total agony I could not hold still for an examination. A couple drops of cocaine solution in that eyeball and the pain went away. Nothing. Nada. Back in the '70s I also knew a dentist who used it...

    Which government? It's a global problem, you know. Climate doesn't stop at the border. Other countries take it much more seriously than the US does. We waffled out of the Paris Accords because of the denialist movement in the US.

    The hydrogen ions are freed from the water molecules by combining with SO2 to make H2SO3. It's not the sulfur, it's the sulfur dioxide.

    Sulfur compounds have to be in the stratosphere to limit insolation. Volcanic explosions lift them up there. At ground level where vehicle exhaust and smoke stacks are, they contribute to acid rain.

    Just close down the ports and factories. They can have all the electricity in the world, and nothing to plug into it. A big slice of humble pie would do them good.

    Here is a map as the local grids exist. Texas doesn't connect to anyone. There is no way to get power from the West Coast to the East Coast, and even getting wind power from the midwest to the east coast is a big loser. There is no national electrical grid. It does not exist.

    California Targets Private Property With Latest Water Well Fees, Charges: Report

    California gets demonized a lot. It's the mass social equivalent of an ad hominem attack. I don't know the Latin for that, but California gets to solve it's own problems and reap its own profits. Nobody else gets a vote. I have family living in California, Texas, and Florida. Not my kettle of...

    California Targets Private Property With Latest Water Well Fees, Charges: Report

    Some areas in California are putting water back down the wells during the rainy season to recharge the aquifer. Lack of regulation is limiting that. Why go to all the trouble and expense of recharging an aquifer if the golf course a mile away is going to pump it out for free?

    There is no "national grid." It would be a good idea to build one, if the Luddites in Congress would ever get out of the way and start addressing America's future. As for supply capacity, we have to rebuild most of our generating capacity anyway. It wears out. The old system was never going to...

    California Targets Private Property With Latest Water Well Fees, Charges: Report

    Maybe in Arkansas. Here in the West, we have things called water rights. Water on your property is not yours unless you have title to it. By state law, every home has water rights for domestic water and 1/4 acre of garden or lawn. Anything more than that requires senior water rights, and you can...

    That's not a lawn, that's irrigated pasture. Plus, your side of the Rockies gets summer moisture. Your lawn is not relevant to areas that do not.

    Long haul trucks spend a lot of time just sitting. That's why the truck stop parking lots are full, and then there are the deliveries.

    Are you a prepper?

    I think the TEOTWAWKI preppers are a little extreme. When I have mentioned disaster prepping on some groups, I have been derided as a "weather prepper," and told that I was not a real prepper. I have had visitors during disasters who were convinced we still had power when the light was an...

    Are you a prepper?

    I think prepping is an urban phenomenon. On the farm, it's the way things have always been done. It's the difference between being a consumer and being a producer. Other than canning, pickling, smoking, and preserving, my primary prep has been economic. No debt. If they want to dig me out of...

    California Targets Private Property With Latest Water Well Fees, Charges: Report

    An acre foot is a lot of water, and irrigators have been pumping "free" water out of the ground without much incentive to adopt more efficient methods. The water table is dropping, and if irrigators don't start conserving they will drain the water table entirely. Some small towns that rely on...

    If you are talking solar, wind, or hydro you are pulling heat out of the environment and repurposing it to make hydrogen, so it's a push. There may be local effects, but globally there would be none.

    Maxwell's Demon is a thought experiment. The demon was tasked with sorting molecules by energy or concentration, thus reversing entropy. Physicist jokes can get kind of obscure.

    I have imagined it, which is why I don't think it will ever happen. Replacing petroleum with electricity would require a complete restructuring of our transportation system, including the end of long haul trucking and short commuter flights. Rail runs fine on electricity and uses about 13% of...

    Foxtail and Dogs. Is this real?

    I have a standard poodle. She was aspirated a foxtail that kept burrowing through the lung until it got into the pleural cavity. This caused a gangrenous infection called pyothorax, that required a $12,000 surgery. I had to rely on a GoFundMe to come up with the bucks, which covered about $9000...

    Short course on the three laws of thermodynamics: 1. You can't win. 2. You can't break even. 3 You can't get out of the game. James Clerk Maxwell is not as famous as Einstein, but he gave us thermodynamics, electromagnetic theory, and invented color photography in his spare time. He's right...

    If you scale up wind production by several orders of magnitude.

    I agree. Nobody breaks the 2nd law of thermodynamics - you can't get as much out as you put in. The only way hydrogen would be a viable fuel is if we had unlimited cheap energy to put into it. Blowing steam over burning coal won't do it.

    How are you going to vent it in the summer? Power vents? Blocking the north wall with insulation and 50 gallon drums full of antifreeze will cut the winter heating bill.

    A lady goes to her parish priest one day and tells him, "Father, I have a problem. I have two female parrots but they only know how to say one thing." "What do they say?" the priest inquired. "They say, 'Hi, we're prostitutes. Do you want to have some fun?'" the woman said embarrassingly...
