Fake News Works

JiggaJonson says...

https://climatedataguide.ucar.edu/climate-data is one of the more complete and user friendly sites ive come across regarding climate

and...

Being the fastest growing city isn't directly related to the number of deaths or the temperature in the city. He's the one who made that assumption not bloomburg. I believe that's called a straw-man argument.

As far as deaths from extreme temps are concerned, it's telling that he didnt take the time to isolate extreme temperatures from the natural disasters chart. Here, let me isolate it for you using the same source. https://ourworldindata.org/grapher/number-of-deaths-from-natural-disasters?time=1936..2018&country=~Extreme%20temperature


Or, again using that same source: https://ourworldindata.org/grapher/natural-disasters-by-type focus on ONLY the extreme temperatures and it's clear that the natural disasters of that type are on an upward trend.

Snow Swimming

MilkmanDan says...

It depends on how you define "work". I've done it before; in Finland going from BRUTALLY hot sauna (like 90's C hot) to a lake that was probably just above freezing. You don't want to stay in long, but the cycle puts you into sensory overload mode and it feels really good unless you push the time spent in either extreme too long.

I've also done it in Colorado with less of an extreme temperature gap. Saunas in the US usually run a lower temperature (usually they try to keep them under 120 F or so) but you can make them feel hotter by pouring water on the heater stones to crank up the humidity. I've gone from that to rolling around in snowdrifts, and the effect is again quite nice as long you don't stay in the snow too long (probably under a minute).

Maybe I just have genetics like those crazy Polar Bear Club dudes.

....ever sit in a hot tub for a while, and then decide it's time to go back into the actual pool.

...and then go "Holy Balls, this pool is FREEZING"

That is why your comment will not work, and would instead be, from "augh!" to "AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH"

The Energy Problem and How to Solve it - MIT Prof Nocera

jwray says...

Almost all energy consumed by households is avoidable waste:
* think about the way you fry eggs. 99% of the heat from the burner is going into the air, not into the eggs. This should be solved by using small device that is well insulated on all sides and has an internal heating coil.
* Ovens have a high heat capacity and shitty insulation. More energy is wasted on heating up the oven itself than actually goes into the food. This could be solved by lining the inside of the oven with silica aerogel instead of metal. If an oven is properly insulated it will not feel very warm to the touch on the outside, even after being on for an hour.
* Most of your heating and cooling energy leaks out the windows -- if their inside surface feels significantly above or below ambient during extreme weather, your heating and cooling energy is being wasted and hemorrhaging out the windows. It would literally save energy to have a webcam on the roof and display that image on an LCD inside instead of having windows, if you live in a climate with extreme temperatures (especially in cold climates, as the energy used for the LCD would contribute to heating the house). All ventilation needs can be accomplished through a small portal with a fan (and a heat exchanger, of course).
* Hot water is produced very wastefully by just dumping energy into it instead of using a thermodynamic cycle to transfer heat and produce something cold as a byproduct. Hot water could be co-produced with cold water for AC / Refrigeration much more efficiently than doing them all separately.
* Hot water goes down the drain. This should at least go through a heat exchanger, which would dramatically lessen the amount of work that has to be done to heat up new hot water. A 7 Liter per minute showerhead putting water 30 degrees F above ambient down the drain is wasting over 8135 watts as long as it is running. However, I don't know of any houses yet designed with a heat exchanger between the shower drain water and the intake of the water heater.
* Fluorescent lights. Duh. Incandescent bulbs should be banned.
* Freezers built with the door on the top will waste much less energy to the convection of air when opened, for obvious reasons.

Here ends the lifestyle-neutral list of suggestions. The following would involve sacrificing something:

* Reduce excessive lighting -- if people wouldn't fuck up their retinas by driving just after sunrise or just before sunset, or seeing specular reflections of the sun on shiny cars and buildings outdoors, they wouldn't need such bright lights indoors. A 1 watt LED is plenty for reading. Sunlight could be used in the daytime instead of artificial lights.

Solar Highways!!!

What do these common road contaminants/applicants do to it?

Oil, salt, rubber, tar (because we're not going to be able to do all roads at once obviously), rocks, dirt, rust flakes, hydraulic, transmission, anti-freeze, various other car fluids, gasoline spills, diesel spills.

If an accident occurs how easily is the glass scratched, how much damage can it take before it needs a full replacement.

When replacing/repairing them, how long does it take? Is it cheaper to repair/replace them than it would be to maintain asphalt. How long do they last? Asphalt can go 10-15 years on parking lots if maintained and not overly abused via spills. Roads vary due to traffic and how smooth they are, plows eat them alive when they begin to hump/buckle or become misshapen in some way.

If one breaks or is damaged....does it affect the power generation? How much so? Will it take out city blocks of power like a power line going down?

What if a water main bursts under it or near it....will it support the weight if the foundation is washed away? Will it heave up in a big panel making the surface uneven? Will it breaks the other panels when it does this? Or cause some other damage due to the feed being broken?

How does it handle snow, ice, dust, fog, mist. Extreme temperatures. Can they be salted and plowed or do they self-clear snow somehow?

Most cracking and uneven-ness in road surfaces comes from the foundation below it, some people call them structural cracks..like the foundation of your house might get because of settling. It's also a telltale sign of problems below the surface of the road, masking that problem may not be a desirable quality even though it makes it a more convenient road surface in the meantime. It's like pothole versus sinkhole problems....I'd rather blow out a tire than have my car swallowed by the road.

If they keep this primarily to freeways they can avoid most issues with water mains, gas lines, sewer, etc. But they'll still have storm drains and the underground pipes associated with them, not as much of a big deal if they leak...but if they were to be plugged and a big rain came it can cause havoc with roadways above and below the surface...they don't plan for the water to start flowing up from beneath the roadway.

Finish grade asphalt and concrete work is pretty fast moving stuff when everything else is ready. It's all the sub grade work that takes months and even years.

Be great if it worked, but maybe they should start with sidewalks or bike paths...military base applications...they see some heavy equipment rolling through there, if it lasts through those....

Don't forget radiation-hardening and extreme temperature operation. It costs much more to make electronics function as intended outside 0-70C and in the presence of ionizing radiation.

Doc_M, you should check out the NASA TV channel if you haven't. They're pretty proactive at letting the public know what's going on.

Can We Make A Star On Earth? - Presented by Prof Brian Cox

I do like the light they throw on the process for fusion. There are ALOT of answers to physics at the extremes: temperatures(hot/cold), pressure, quantum mechanical "tricks", speeds, etc...

There is still alot of work to be done! That is what keeps me going, is that singular hope. These are things iconic physicists and sci-fi writers have given us: ie, Carl Sagan.

I like the Gnarls Barkley "Reckoner" cover at the start.

Always probe the extremes; that is where we can see the Universe and it's "rules" fundamentally tested because everything involved is beholden to "physical" controls that even the Universe can't break. It helps our understanding immensely. A good site to keep up to speed is Physorg.

New discoveries, everyday...
