Physics: Heat concept questionEmergency blanket?

For backcountry hikes, in your car or given out after a disaster people use reflective silver or gold colored foil as emergency blanketExplain why they help maintain body temperature even though they are very thin(Would such an emergency blanket also help keep a reptile warm?)

Answer:

Aluminium does not rustEither the pipe is a small steel insert, or it is dirt.
a powerful high quality motorbike won't rustCoat all the threads with a lite grease and get ready a lite oil on all the bolts and screwsThe chain could have a coating of oil on it already.
Aluminum oxidizes but does not rustThe rust has to be from something else.
Sorry, but aluminum does not rust, it will oxidize to a white powder like substance, but no rust If you are actually getting rust, then there must be steel in the frame somewhereThere is a product use by somebody shops and sold in parts stores that will encapsulate the rust, an stop further rust action, expensive but good that can be poured into the frame.
Silver and Gold are some of the most reflective materials known to manBut this doesn't only apply to visible light (think about other forms of energy on the electro magnetic spectrum)Infrared energy is heat and these two elements reflect it very wellThese emergency blankets reflect the dangerous amount of heat from forest fires away from the person, and can keep you warm at nightReptiles do not produce enough body heat to survive and these blankets would reflect what little they do produce to keep them warm enough to stay alive.
