Have we discussed solar roads?

I lived next to a train yard from 2011 to 2017.

It was a redpoint5 comment.

Frankly, I don't know about the dirt in the air, there's a main street between me and the yard. I am sure about what the French call metal hurlant.

If you see visible dust the day after cleaning, you have a contamination issue.

In the level 2 clean rooms back at hughes, you could clean the whole room with one handi wipe and not get it visually dirty.

I have a whole-house fan that blows through a MERV 11 filter. My standard for comparison is a paper towel on the car's windshield. If two days from a clean windshield it's light gray that's normal. While the accelerationist arson is in season, dark brown in two days.

SA's use of hyperbole is rubbing off on me.

At my previous job, I would on occasion pull a perforated tile up from the floor of the fab to crawl underneath to locate a network jack. Presumably this is where weeks/months/years of dust would accumulate, and I crawled in a white bunny suit. I'd find dropped pens, fasteners, and paper clips, but upon exiting the subfloor I appeared just as clean as when I entered.

That was another nice thing about servicing PCs located in a clean room; there was no dust to contend with.

It amazed me how much silicon dust could accumulate in PCs located in the rock crushing rooms and not affect operation.

In Arizona if you crack your windows you will see dust on your dash the day after wiping it, although I seemed to get more from my sun shade than the desert.

Hey, thanks for stopping by..... your thread.

I decide to get away from the ecomodder stuff so I went to Slashdot. The number one story? The Pinnin Farina Battista.
tech.slashdot.org Sportscar Manufacturer Debuts World's First All-Electric High-Performance Hypercar (newsweek.com)

With an emphasis on the company's "Pure Sound" philosophy and drawing from music theory, the bespoke design of the car is built to have a core frequency of 54 hertz (hz). Wanting to provide an emotional experience for the driver, the organic frequency will rise in multiples of 54 hz as the speed increases.

When the car reaches 432 hz, the design of the soundscape is meant to evoke an emotional reaction that drivers come to expect from a hypercar.

What exactly is this 'emotional reaction' of which they speak, hmmm? My bet is that they are using Yamaha elctric motors, but I haven't seen confirmation. Yamaha Electric Motor for Hyper-EV | Prototype

The rest is just regular Slashdot-y stuff

In places I worked the floor is where the filtered air came from. Also the Halon which was weird because the halon opened all the floor tiles trapping you in the room.

We tore apart a pc that was being replaced at a cement kiln and were surprised that it even worked because the fan was so worn that it didn't spin and everything had a 1/2 inch of cement on it.

There was a mention of solar roads on the news, but I cannot find anything!

Thanks for keeping us up to date!

Still more expensive than a solar farm on the ground.

I have yet to read here a strong case made for why road surface Solar is a good thing, plenty of valid downsides shared so far.

I look at it a little differently, seems like the issue might center around better utilization of real estate, which has merits.

My suggestion, there is a lot of land that is taken out of typical use by high overhead often high voltage long distance power lines. I don't believe the powerlines cast any shadow on to ground mounted solar panels at these heights, the areas are already allocated/permitted, they are somewhat secure, they provide some lightning protection for the solar panels. they have already an access road in place, the ground is cleared of vegetation and often graded/level, the powerlines terminate to where solar needs to go anyway I suspect, and they already are in place and take up a lot of acreage. The one question above my pay grade, is solar effected by any induction effects that are bothersome at the distances and location this solution be utilized at?

So why not?
