snow plow WILL carve grooves on the asphalt on worst case scenario

I don't see a problem with that. When I had a CRT I would use any old glass cleaner on the screen to get the muck off it, never bother about finger marks, etc. On my LCD with the strange flexible(ish) screen I take a lot more care! If you use brute force stuff designed for old tech on your new tech you are asking for trouble, and if you can't change that brute force you're never going to advance. Thus changing the ploughs makes perfect sense (and trivially cheap compared to the cost of the  road) for the implementors. Those with a grudge won't see that using a forge to make ally parts is silly.
I was trying to make point about their awesome skills for solving problems they have created themselves by doing certain things in certain way. It's not just about the ploughs they have to change. They have to change everything. When does a solution create more problems than it solves?

Get plasma screen and it has tempered glass  :-DD That tempered glass protects the fragile plasmas to some extent, however it also creates really annoying reflections even if it's flat. Plasma screens are awesome when there is no sunlight entering the room. Just be careful with that tempered glass, even if it's hard it might shatter really easy. See? Tempered glass solves every problem!

There is also the issue that the asphalt is basically a flexible roof for the subgrade. Roads move and need to be formulated to reduce cracking, handle heat, cold all at the expense of durability. What will be used to keep all the tiles in place?

I'm sure they will come up with something really awesome. If it's anything like what they have done already, solution should be something almost unpractical. Maybe they will use some natural substance like asphalt or tar?

Solar roadwaws are just stupid, noting more than that. We got plenty of roof top. and we got plenty of other areas that we do not use, so no need to re work the roads. and if ti works on 230V AC we can carry the current approx 90m until we need to transform it to some thing useful. And the losses with the electronics. And melt snow! Get real. not a option in Sweden. the power needed is just silly.

So the original money the got from the government was where the original tiles came from?

Am I correct in assuming that was a feasibility study and it failed (no more funding). It would be interesting to see the final govt report or reply on that if it has one.

We are still in R & D, and we haven't even calculated the cost for our prototype. That will come next month as we get our final report ready for our Phase II contract with the Federal Highway Administration. And even if we had those numbers available now they would have no relevance to the cost of our actual product.

Next month... month ago? If it's always next month then that is genius.

This product would be good but not for roads.

I see it as useful for parking's  and similar, not high volume traffic areas.
If it could just generate during the day all the electricity needed to light/de-ice during the night that would be great.
That would be revolutionary.

They're taking the product a bridge too far.

36-watt (assume is watt/hour) per panel currently so how long will it take to pay for itself?
so $10000 / 36 = $278 per Watt/h

They can come with creative revenue sources using the addressable LEDS.  For example, ads, custom lane marks for paying business (e.g. a red line that leads you to the nearest McDonald) , dynamic preferred lanes for paying customers with real time lane bidding between cars, and so on.

(I am not a supporter, just pointing new possibilities).

June 18th: We were sworn to secrecy until now, but Solar Roadways was invited to the first ever Maker Faire hosted by the White House. The event will feature Makers, innovators, and entrepreneurs of all ages who are using cutting-edge tools to bring their ideas to life. We we're honored to be chosen. Off to the White House now!

Several bridges too far if you looks at all the wild claims on their website!

Just the training and the man hours of qualified installers cost will be exorbitant.

They do have that listed, as well as leasing the cable runs for data, phones, power etc as revenue.
The problem with the LEDs is that they will have to use light guides to make them visible at the required angles.
And McDonalds will just put a tall sign visible from the Highway as they've been doing.

Exactly!

I'm not defending them, just stating what they claim as source of revenue. I think the whole thing is nuts and a waste of naive people's money.

Dave, Loved your video. You should of kept it up even though (iTunes update.... (At Least it wasn't clippy asking "I see you are trying to record a YouTube Video. Would you like me to start Windows Movie Maker")) the video had edit issues. It did show a level of frustration you had with the whole concept. It made you come across as more a "real life person" than a perfectly edited video.

Nah, hadn't been up long, and the new video is better for it. Have added some extra stuff I was going to cover in extra videos, so it's better for as a standalone video now.

Where is the video? I can't seem to find it.
I'm not saying we should kill all stupid people. I'm just saying that we should remove all product safety labels and let natural selection do its work.

OK, new video is up:


Some extra stuff added on LED power output and some calculations on payback period.

I didn't watch your "New" video because I though it would be a re-edit but I will catch up on it now :-)
