I recently got rail road tie ends to burn in my fire place. They are, ofcourse, untreated. I was told they are safe and good to burn??? I dont know the difference between woodswhat kind should i get and what kind should i not get.
Radiant barrier coating is too expensive to be practical at this time.
NOOOOOOO don't do that! It would signal the aliens!
Instead just add good dolar panels on roof. You will end up getting free electricity and using up about 25% of light energy.
Lightning happens from the ground to the sky. The reason for this is because protons and be drawn from up from the ground. This term is usually called polarization effect. The reason lightning zig zags downward it's because of the electromagnetic field applies a force to moving charges. So that is why lightning is never perfectly straight. Lightning does make thunder. When lightning flashes it releases incredible amount of heat around 40,000 degrees Celsius. When the air heats up it quickly expands and cool quickly with contract. The air contraction slams the air molecules together and the begin moving back and forward making sound waves that create thunder. The contract creates the sound we hear is like a crack and pop explosion sound of thunder. As the air moves back and forward it makes soundwave that gives us that rumble noise we hear for a few seconds.
Most roofing material is very reflective in order to keep the heat off. It's not perfectly reflective, but disperses the light energy away to keep the attic from getting too hot. Tin roofs are probably more reflective than tile. If you made rooftops like mirrors the airplanes might have a problem when flying over.
