International ClassF17C 001/00AbstractA low heat-leak cryogenic system comprising a cryogenic fluid, a first lamina having an external side facing toward and exposed directly to, or indirectly to, the cryogenic fluid and an internal side facing away from the cryogenic fluid; a second lamina spaced apart from the first lamina, and at least one block or layer of coherent aerogel extending from the first lamina to the second lamina. In another version, the aerogel is in a gaseous environment having a pressure not greater than 250,000 micrometers of mercury. In another version, at least one of the lamina is flexible so as to at least partially transmit an external load, such as that imposed by the atmosphere, to the coherent aerogel, and the coherent+ aerogel is capable of at least partially transmitting a load imposed on it from one lamina to the other.Other References
