Hexagonal prisms for constructing a wall

A module for constructing a wall comprises a frame forming a hexagonal prism and defining an interior space. The frame is formed from a pair of hexagonal end caps tied together by a plurality of elongated stringer members disposed at corresponding vertices of said hexagonal end caps and extending generally perpendicularly therebetween.


Methods of fabricating metallic fuel from surplus plutonium

A method of fabricating metallic fuel from surplus plutonium may include combining plutonium oxide powder and uranium oxide powder to obtain a mixed powder with reduced proliferation potential. The mixed powder may be electroreduced in a bath of molten salt so as to convert the mixed powder to a first alloy.

Tracking-free high concentration ratio solar concentrator

A stationary concentrator able to concentrator sunlight with high concentration ratio is consists of a compound parabolic concentrator (cpc) and a prism array. A chamber with its thin transparent wall shaped into cpc and prism array is used to form a bulb-like close structure solar concentrator.


Optical differential solar tracking system

A system and method of using differential optical signals to track the orientation of a solar surface or surfaces is proposed. Two dispersive prisms or gratings arranged in a mirror-symmetric fashion are used to decompose light into its constituent colors, and the gain of a differential amplifier circuit based on the difference of the frequencies of single color collimated light produced by the two prisms or gratings is used to maintain the on-sun orientation of the solar surface or surfaces.
