A solar insulation capturing and transporting system includes a solar insulation receiving member configured in combination with a dual walled conduit. Fluid is flowed through one portion of the conduit and into the solar insulation receiving member and thence into a second portion of the conduit. Heat energy captured in the fluid is then transferred, in the flowing fluid, to a use location where the energy may be usefully exploited.

System for providing a secure file service includes an MLS file service module (300) comprised of a cryptographic processor (302). The MLS file service module also includes an MLS file system (301) hosted by the cryptographic processor. A secure user processor (402) includes programming and communications hardware for requesting at least one classified file from the MLS file service module. The cryptographic processor includes cryptographic hardware and software to decrypt the classified file. The cryptographic processor is also performs an integrity check on the classified file. Once the file is decrypted and its integrity checked by the cryptographic processor, the MLS file service module serves the classified file to the secure user processor in decrypted form. If the classified file is an executable file, the method also includes selectively enabling a write function for program memory of the secure user processor. This write function is disabled immediately after the classified executable file has been loaded into the program memory to guard against self modifying programs.

A solar panel is disclosed that can be daisy-chained with other solar panels. The solar panel automatically generates output alternative current (AC) power that is in parallel with input AC power coming into the solar panel when the solar panel senses the input AC power so that the solar panel operates as a slave in this state. The solar panel automatically generates standalone AC output power when the solar panel fails to detect input AC power coming into the solar panel where the solar panel operates as a master in this state. The solar panel generates the standalone output AC power without any reliance on input AC power generated by a utility grid and / or other AC power sources external to the solar panel.

An improved solar collector pipe that directly conveys fluid to be heated and collects and transfers solar energy efficiently and directly to the internal fluid, thereby maximizing both the amount of energy transmitted to the internal fluid and the peak temperature attainable by that fluid. The solar collector pipe includes a transparent portion for admitting solar energy into the solar collector pipe. Internal to the solar collector pipe is an absorbing portion for absorbing solar energy. A conduit portion is also included and comprises a reflecting surface thereon for reflecting solar energy received through the transparent portion onto the absorbing portion. In embodiments of the invention, the transparent portion, the conduit portion, and the absorbing portion together define at least one fluid passageway for conveying the fluid. In other embodiments of the invention, an internal conduit defines a fluid passageway for conveying the fluid. The internal conduit may be supported within the solar collector pipe and supported by heat-absorbing portions, or may be placed between two solar collector pipe sections to form a single solar collector pipe with an internal conduit extending therethrough.
