摘要:
A solar energy collection conduit (10) comprising an optical concentrator (40) incorporated into an outer tube (30) having a sunlight-transmitting ceiling (32). The concentrator (40) focuses, guides, directs, and/or otherwise concentrates sunlight towards a pipe (50). Fluid (60) conveyed by the pipe (50) can be heated to very high temperatures (e.g., up to and above about 100° C., about 200° C., and/or about 300° C.).
