Worlds Best Heat Shield - Rat Wheel Spinning
So who would pay 60 bucks for the worlds best heat shield?
Basically I am thinking of using aerogel as an insulator between the two sheets of metal.
Ideas?

Its 45 dollars for a liter of granular aerogel. I don't need solid blocks of it.

gold foil + aerogel sandwich would be about as effective as you can get. realistically you can just use polished aluminum. no need for stainless steel--its lower thermal conductivity doesn't matter since its not conducting much.

While it would be super rediculously effective. like...about as effective as i can possibly imagine. What about moisture? I know it can play a pivotal role in the deterioration of aerogel. I don't think layers of metal will keep it out =\
That would be sooo hot btw. and by hot, I mean cool. if it wasn't for the fact that there's radiant heat in the engine bat and the proximity to the exhaust in general you could put your hand on that heat sheild while the turbo was running full blast.
Actually, I have a manifold heat shield as well *hmmmm*. what I really would need though is some way to effectively evacuate hot air. Oh god, I have so many ******* good ideas and no money to play with and experiment. Wish I did, because then I'd have a reason to ask for my magnehelic gauge back from scott.

Commercial manufacture of aerogel 'blankets' began around the year 2000. An aerogel blanket is a composite of silica aerogel and fibrous reinforcement that turns the brittle aerogel into a durable, flexible material. The mechanical and thermal properties of the product may be varied based upon the choice of reinforcing fibers, the aerogel matrix, and opacification additives included in the composite.
