EEVblog #1269 - Solar Roadways SR4 DATA Hilarity!
« on: December 04, 2019, 03:52:16 am »
We have data from the new Solar Roadways SR4 installation, and it ain't pretty!
A comparison with a nearby installation of existing rooftop solar, and how much energy does it take to melt snow?

Data from SR4: https://monitoringpublic.solaredge.com/solaredge-web/p/kiosk?guid=1e085701-ccb3-4ce5-b107-86e3b5e831dd&locale=en_US

In the video you comment on the pinpoint melted patches. There is something weird going on there.
In the The Demise Of Solar Roadways thread you posted a screenshot from Dec 1, where the small patches are visible. I checked live feed some twelve hours later, and there was the same pattern, same size. That would imply the heaters were either not turned on, are physically very small, or the melted patches are not melted by the heaters, but rather by something else (ie. the LED drivers).
In any case, wouldn't this lead to some potentially harmful thermal gradient?

Ah yes, the gift of hilarity that keeps on giving!

With the current political climate here (no pun intended), I think this debacle will continue to get funding, just to pleasure the public to make it seem the president's opposition is doing such a great job at saving the planet (and thus win votes in 2020 to stay in office).  :palm:

I do look forward to an actual road way for this thing, just to see the fun of this thing really get torn up. Should be some fun.
 :popcorn:

Perhaps a poll to see how long it will it take until structural failure, perhaps?

Maybe they're on to something here, in this quiet segue to Solar Freakin' Walkways.

Yes, it did seem to take some time. Interesting that you note 12 hours timestamps with no change.
I wonder if/how the heaters are controlled?

Someone posted on Youtube that we should crowd fund a traditional panel system and offer it to the council for free to mount on top of the dunny block next to Solar Roadways.
The direct power output comparison would be hilarious!

The discussion about it that goes on and on too. Does anyone really care anymore?

At least SR seem to be taking what they learn from the trial and using it to make improvements.

I see from their Twitter they were in Melbourne, Australia recently. Pity we couldn't have heard from them first hand.

What no one cares about is your trolling.

The discussion does seem to go on far beyond what a marginally useful product like solar roadways would seem to merit. You can infer something from the number of forum members that show even the slightest interest.

It is a valid question that might show whether continuing to rant about it is of wide interest to the majority of forum members. If you choose not rush to judgement and assert I am trolling (i'm not) you might have been able to see if anyone said they really wanted the blog to be geared more toward this sort of tabloid pulp type video. Content that is of a highly disposable nature.

It is of no interest to me and I would like to see if anyone at all is wishing to encourage you to waste the blogs bandwidth on such drivel.

I tend to think such a quick accusation that I am trolling you is a defensive response. You should just ignore it. I didn't pose the question to you anyway.

When Mikeselectricstuff or J Diddy start posting in these video comments then I might think the technical people are seeing something worthwhile. Me, I'm just a hobbyist who would rather see you do something interesting.

I like these updates because I don't have time to follow this ridiculous project myself. Like Dave says though, he makes what he wants.

That sounds like a good plan. Let's do it!  :-+

All we need is some marketing. What to call the idea?

So - do you think you have the right to go to Dave's home and tell him how to arrange his lounge furniture and what he should eat for dinner? ... Because that's what your "opinion" seems to look like.

Dave's blog = Dave's rules.  I didn't think that was rocket science, but maybe I'm mistaken.  It would be more appropriate to acknowledge the privilege you have in being allowed to share.  Don't like something? - then don't watch.

I am, however, fascinated at the energy you expend complaining.

The whole "snow" thing is a non-starter. No need for any calculations...

As soon as any snow lands the panels' output will drop close to zero because it's covered up. It's not going to melt anything, ever.

It raises a question though: Why isn't the mainstream press all over this as a bad idea, a waste of money?

The mainstream press is largely the organ of the managers and investors, collectively speaking (the 10%, as some sources call them). They operate the MSM solely to sell themselves as superior and indispensable. The only place to find truth is in the insider financial press, and even there you will find plenty of fatuous self-congratulation.

How many times does a bad idea need to be debunked due to next frekking solar initiative taken? The point here is i get the taste that frekking solar roadways is part of man made climate change scam GRETA backed by Soros and the liberal globalist fascist TECHNOCRACY people as it have been proven many times already.

Ask your self why is frekking solar roadways and all the other climate change green deals constantly built/proposed despite the initiators knows it wont work or have bad performance? To keep alive the circular argumentation TECHNOCRATIC New World Order people constantly uses? to, behind the curtain, push their real agenda? It's all about deceive and deception and distraction of people whos not informed to then be the front shield of TNWO without knowing they are so the agenda more easily can be pushed through, therefore exposure of TNWO agenda is quite important in whatever form its done, in this case by David debunking frekking solar roadways!

Aldous Huxley, New brave World is good read...basically describes frekking solar roadways already in 1931, one year earlier TECHNOCRACY cult movement was invented, and one of their priests was no one else then Elon Musks grand dad  Dr. Joshua Haldeman.....  You didnt see this coming did you troll!  :D

(If you are interested about TNWO scam crap you can go to CORBETTREPORT.COM and TECHNOCRACY.NEWS)

Wilfred, I am long beyond giving one rats arse what you think about me.
You have been criticising everything I do and say for years, relentlessly. Trolling me by a thousand cuts.
I encourage people to criticise what I say and do, but you have overstayed your welcome.
Seriously, stop it, like I've told you a dozen times before, if you don't stop I'm going to eventually ban you.
People might look at this response and go WTF, why, but they haven't seen the literally hundreds of times you have done this, and the dozens of times I've had to warn you.

It pulls the heater energy from the grid. This is why they need the rack of big PSU's inside the control box, photos of which have been shown on here somewhere previously and in one of my videos.

We can easily make the assumption everyone knows the heat capacity of water going through a phase change but I wonder how many people who do not have a scientific background or do not have cold country backwoods camping experience actually have a good intuitive feel for this. The first time Joe average goes winter camping in Canada and tries to melt snow for coffee  he has  his eyes opened.
