Socialist robber barons and their crony capitalist .... hard at work conning you out of your tax dollars and funneling them into liberal corporatist pockets. Where is the lib outrage?

Of course, there's no outrage about the millions that Trump is wasting and funneling into his own pockets with all of his golf trips.

I remember growing up in SoCal, every summer there'd be at least one story about someone frying eggs on the sidewalk. And the sidewalks were gray concrete. You usually did not try to walk on them barefoot past early morning. And the title of the topic is the usual distortion of reality. As the article makes clear, it's light gray, not white.

Even in NYC during heatwaves, someone was always frying an egg on the sidewalk.

California officials are hoping their latest attempt to stem the rising tides of climate change leads to a more socially conscious — and cooler — summer.

Officials in Los Angeles have been painting streets white to reduce the effect of urban “heat islands” and combat the effects of climate change.

The LA Street Services began rolling out the project last May, which preliminary testing shows has reduced the temperature of roadways by up to 10 degrees. The project involves applying a light gray coating of the product CoolSeal, made by the company GuardTop.

While each coasting could can last up to seven years, they are also pricey, with the estimated cost of $40,000 per mile, the L.A. Daily News reported.

its all sceincey so you right wing idiots wont understand


its a test of the idea

like any new project the cost will be the most in the beginning


you idiots don't realize how quickly the heat destroys the roads


its not just paint its sealer


if it works better than the resealing they MUST do every few years with a dark asphalt resurfacing and makes all the neighborhoods COOLER then it can be applied in a cheaper per mile cost if they decide to employ this idea city wide


and it will reduce the use of airconditioners in every neighborhood it is used in huh


the right hates news ideas


they cant think past their own noses


so they spew hate on any new ideas

trying to change the subject because you go your ass handed to you?

It doesn't matter how many times you repeat it. If it's not one of their lies, they'll never believe it.

How quickly do you think it will get dirty and negate any supposed benefit? Oh, but cleaning it will come with an excessive carbon footprint! And it's not like Cali has a bunch of water to spare for cleaning the streets. Even if you buy into climate alarmism, this is a fucking stupid idea. My god you climate alarmists are the dumbest religious group ever.

Of course, you never see a street sweeper now on any California street [/sar]

Wow. It took 125 posts until someone realized a sealant of any kind on a street will reduce traction. Good call Sir.
Cal. is the "land or hotrods." Many hotrods there run drag slicks or at the least, very wide street tires.
Asphalt is porous, and like your normal street tire, it aids in channeling water. Now, fill those pores with a sealant,
it makes the roadway smoother. Has anyone ever noticed your vehicle hydroplane? If it rains on those sealed roads
it will cause even a normal tire to hydroplane, and coupled with the rubber, dirt and oil deposits on the roadway, it
can be a recipe for disaster.
Has anyone ever heard of the "bleach box" at a drag strip? They water it down with a garden hose to help the cars
break traction to do the burnout. They sure wouldn't "seal" it or the cars would become uncontrollable because it
would become too smooth. Burnouts heat the tires (with friction) so they become sticky for better grip on the track.
That, and coupled with the friction of the porous asphalt, the burnouts are relatively short.
Maybe a sealant would drop the surface temp during a hot sunny day, but it would become a safety concern for any
thinking individual when those roadways become wet.

The usual ignorance. Asphalt roads are usually sealed to make them last longer. It saves money in the long run.

Why are houses painted white in hot regions? - Quora

https://www.quora.com/Why-are-houses-painted-white-in-hot-regions

The reason why houses are painted white in hot countries is because white is not a great absorber of heat. Instead white does not absorb heat, it reflects heat. When the heat waves comes towards the roof of the house, the white paint reflects some of this heat. This will eventually cool the house down. Interior Painting ...

Cool roofs: beating the midday sun with a slap of white paint ...

https://www.theguardian.com/.../cool-roofs-beating-the-midday-sun-with-a-slap-of-whit...

Apr 12, 2017 - Indeed, cool roofs aim to do exactly the opposite, reflecting as much of the sun's energy as possible. A flat roof in the midday sun receives about 1,000 watts of sunlight per square metre. A dark roof will absorb most of this energy, heating the roof and underlying building, as well as the surrounding air.

If only we had an efficient way to convert heat into electricity, cooling things off at the same time.

Ha. I used date someone who grew up in the neighborhood right beside Mt. Vernon. She had moved by the time we dated but we did a drive-by of her old crib once

I don't like concrete highways myself. I think it is a bit of a rougher ride and you get more road noise off those roads. I am not opposed to them necessarily. I understand they have fewer potholes in cold weather and are not as vulnerable to road salts and such. I am not sure the Kool Seal thing would work very well in areas that get regular rain. Could be slick to hit a long patch of it I would think.

The problem in SoCal is that there are long periods of no rain. Then when it does rain, the rain loosens and mixes with all the crap that's built up on the roads, making things very slick.
