I have no real idea if this is "better" than the existing materials...perhaps someone with knowledge could comment) Interestingly it is very heat resistant, they give examples of applying a blowtorch for 5 hours and having the other side be cool to the touch. Check it out...now imagine making a dewar with this in the construction and some kevlar wrapping to provide kinetic impact protection...how much safer could we make them? what would happen to todays dewars if a fire burned in the storage area? ------=_NextPart_000_0055_01C285D9.DFC2D3C0 Content-Type: text/html; [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=20407
