Welcome to the Colorado AR-15 Shooters Club Discussion Forums.
Just like any other "green" technology. How much Fossil fuels does it consume to get the benefit of the power from the solar cells.
I just love how electric car companies and other green technology is advertised as "clean energy" when you plug it into an outlet that gets power from a fossil fuel power plant. Or it burns more fuel to produce than it saves in a clean energy trade-off.
I typically agree, but coal fueled power plants have a much better use of the energy than cars. The energy efficiency in cars is very poor, <10% of the energy created by combustion is used to power the vehicle. The rest just goes as heat and exhaust. Power plants are ~35%, IIRC.Originally Posted by rbeau30
Internal Combustion Engines are closer to 20% efficiency. I believe incandescent light bulbs are 10% light and 90% heat.
Even with the texturing, a glass roadway has the opportunity to be very slick. This is a fun theory, but the devil is in the details.
Liberals never met a slippery slope they didn't grease.

I wish technology solved people issues. It seems to just reveal them.

Ah, okay. According to this Wikipedia page, Coal and oil are about 33%, and combined cycle plants(they use the heat generated twice to turn generators) are 56-60%
I've been watching this technology for a few years:

I'm not really interested in the panels sitting on top of my traditional shingles, however, if the singles themselves were solar, AND it was cost effective, I would consider doing it. The tax breaks are a scam IMO, like the cash for clunkers program. Someone, meaning other taxpayers are picking up the tab for those tax breaks.
Ultimately, if solar, wind, etc... are going to make it, they need to stand against other energy sources, hydro, fossil, nuclear, before I will consider adopting them. I am certain that when fossil fuels become more expensive, other energy sources will take their place in the market. I am not a fan of having governments picking winners when it comes to the market competition.
If solar roadways are a solution, there are plenty of people, businesses, and governments that will be beating down doors to adopt them. I just hope those governments don't force the taxpayers to adopt over priced solutions to problems that don't actually exist.
Or until some driver doesn't set their plow correctly.

Funny, all this technical info yet all I could think was "Just great. Now there's going to be ads in the roads themselves. No one can escape the bombardment of ads we get."

The video showed that the panels are heated thus eliminating the need to be plowed..
Think they'll effect tire wear?

these things will be great.
just think, they can mandate all cars have an imbedded chip which will be picked up by sensors in the road every...say 100 yards. then they can track you everywhere. they can know everything you do, everytime you do it. cool. plus they can tax you for driving more/ or less (like they do with watering). this will be great, they can shut down your car with the new technology they will incorporate into the system. going to church, synagogue, conservative meetings, gun stores? we will know all about it. sounds great.
no thanks.
and if you think it cant or wont happen you must be living in a dream world.
