There is 150 million kms of vacuum between the earth and sun. Beats the hell out of 1 cm in the thermos. But the heat gets here.

Heat transfer works in one of three ways: conduction, convection or radiation.

The heat from the sun reaches us by (mostly) infrared radiation.

It's an insulator. Or has a vacuum between the skins. No air= nothing to transmit the energy. So it stops energy escaping or entering via the vacuum barrier. :P

That's why I asked about warmth in sunlight.

I knew that. Preeny might have forgotten. That's why thermoses are silvered to cut down radiation losses.

Sorry dude, I get what you mean now.

And i should have elaborated more than what i did. But i AM right, still. :P

It's actually a thin layer of aluminium on glass. The same as a mirror. :)
