my new invention please read?

Question

are you sick of shoveling do you hate the snow?
well my invention takes care of all that! under the pavement is a hole line of coils that is heated up using solar power energy! once it snows just turn it on and in a matter of minutes BAM! its gone :D once the snow melts it flows dow to the end of the drive way and goes down a drain so it isnt all icey and it is properly disposed of.its good for side walks driveways and porches safe to walk on and for kids and pets! (this is not a real product) just an idea!

Answer 1

Not a bad idea, just not completely thought out. Heating coils, especially of a size to melt the snow off of your driveway, use a LOT of power. Solar cells, regrettably, produce only a little. How about this instead? Run pipes through your driveway, and then run them a few feet under it as well, and have a pump moving a fluid with high specific heat through the plumbing. Something like automotive antifreeze mixed with water would probably work just fine. Just a few feet down, the ground temperature is a nice, even 55 degrees, more than warm enough to melt snow and ice. Use the solar cells to power the pump. Now, go make yourself a million dollars. When you do, remember to thank me.

Answer 2

Yes, it has been done, but seldom. It's a wasteful use of energy, whatever the source. Melting the snow takes a lot more energy than shoveling or plowing it. To melt it in minutes would take a tremendous amount of power. Try calculating the latent heat of fusion for a cubic foot of snow.

Answer 3

eemmm...I think someone have been done on this invention...Did you see the American Invention Show?

But...I'm a little confused...If you used solar energy..., there was no sun at all...

But its okay...atleast you got the idea...

Answer 4

I believe it had been done, I know there are eletric driveways that work that way.
