Not exactly generating electric power, melting snow and what not, but somewhat practical if it works. Doesn't say what it does to the environment over time...
Practical for illuminating a pathway, yes, perhaps.... but this is a discussion about
SOLAR FREAKIN' ROADWAYS that generate power and solve all the world's energy and roadway needs with one breakthrough product.
Even though it is essentially a side-thought,
SR can't even get solar powered illuminated blinkies working let alone generate the actual useful energy that is supposed to be the main purpose! There are plenty of far,
far better ways to light a pathway than
SOLAR FREAKIN' ROADWAYS ...
THE SCIENCE IS NEVER SETTLED ON ANYTHING!!!!!
Well, barring some new and novel way to break (or at least make very bendy,) the fundamental laws of physics, there
are some certain things of which we can be sure... Like the fact that you can't get more energy out of
ANY solar panel than actually comes from the sun, so things like melting the snow on a roadway using the power harnessed from the sun using (even 100% efficient, theoretical) solar panels mounted down in the road that the snow is falling on
are actually impossible.
(Again, unless you can find new, undiscovered physics or find a way to somehow turn up Sol's luminosity, for example, but that seems like it might have some unintended consequences beyond melting the bit of snow on the road!
