Abstract:
A directional solidification furnace comprises a crucible assembly including a crucible for containing a melt having walls and a base with an opening therein, a crucible support for supporting the crucible, and a lid covering the crucible. A plate is received in the opening in the base. The plate has a higher thermal conductivity than that of the base. The base can include a composite having an additive such that the composite base has a higher thermal conductivity than a comparable without the additive.

Abstract:
An energy recovery system 100 in a suspension system of an automobile, the energy recovery system comprising an energy recovery unit 101 coupled with a shock absorber 102. The energy recovery unit 101 further comprising a direction control valve 103, a control mechanism 105, a linear generator 106 and a power electronics unit 107 wherein the system is enabled to convert the linear motion obtained in the shock absorber to a reciprocating motion in the double acting cylinder using the direction control valve wherein the reciprocating motion enables the piston rod having the linear magnetic array to reciprocate in the linear stator to produce electrical energy which is stored in the electrical storage unit 108 via the power electronics unit 107.
Abstract:
A method for texturing a photovoltaic module ribbon on a photovoltaic cell including a plurality of first electrodes on a first side and a plurality of second electrodes on a second side, and coupling a first photovoltaic module ribbon to the plurality of first electrodes. The method also includes positioning the photovoltaic cell on a textured base having a texture embodied thereon, where the first photovoltaic module ribbon is substantially contacting the texture. The method further includes coupling a second photovoltaic module ribbon to the plurality of second electrodes, and transferring the texture of the textured base to the first ribbon using heat energy released when the second photovoltaic module ribbon is coupled to the plurality of second electrodes.
