The present invention discloses a portable solar tarp or a field portable battery charger employing a solar tarp, utilizing flexible solar panels, solar fabric, or solar film. Around the perimeter of the solar tarp is a series of attachment points for straps. The attachment points can be grommets, loops, buckles, hooks, buttons, or grab loops and lines, and to which connected various straps (webbing, line, cord, or cable). The present invention further discloses a versatile, adjustable strapping system utilizing straps, buckles, and hooks. The present invention strapping system can attach almost any object to nearly any other object, such as back packs, luggage, vehicles, boats, permanent and portable shelters and buildings, mechanical equipment, and natural objects such as trees, rocks. The solar panel according to the present invention can have the photovoltaic cells wired individually, or in a single line, because when parts of the photovoltaic system is subjected to shade, or if due to space constraint, parts of the photovoltaic system is covered or folded away, the remaining photovoltaic cells with useable energy are still able to function at peak capacity, since the covered cells will not become an energy drain upon the remaining cells. Further, the photovoltaic system is able to harness all available energy, regardless of the required or desired voltage and/or amperage for the system, thus converting any and all available energy into a useable current to either recharge batteries, or power a load.

In this device for controlling the temperature of a battery of cylindrically-shaped electrochemical cells placed side by side, heat is conveyed by the flow of a heat-conveying fluid, which flow takes place inside a double wall whose section is in the form of circular arcs interconnected at their ends so that the junction points between the arcs are substantially in alignment. Relief is disposed in a baffle configuration inside the double wall to constrain the fluid to flow parallel to said section, alternately in one direction and then in the opposite direction. The wall is disposed against the battery in such a manner that each of the circular arcs is disposed coaxially against one of the cells.

The present invention comprises a new nanoscale metal-semiconductor, semiconductor-semiconductor, or metal-metal junction, designed by introducing topological or chemical defects in the atomic structure of the nanotube. Nanotubes comprising adjacent sections having differing electrical properties are described. These nanotubes can be constructed from combinations of carbon, boron, nitrogen and other elements. The nanotube can be designed having different indices on either side of a junction point in a continuous tube so that the electrical properties on either side of the junction vary in a useful fashion. For example, the inventive nanotube may be electrically conducting on one side of a junction and semiconducting on the other side. An example of a semiconductor-metal junction is a Schottky barrier. Alternatively, the nanotube may exhibit different semiconductor properties on either side of the junction. Nanotubes containing heterojunctions, Schottky barriers, and metal-metal junctions are useful for microcircuitry.

An arrangement for the controlled production of an essentially linear array of hydrocarbon feed injection jets reduces required clearances and elevation while facilitating modification of the contacting locating a feed distributor containing a linear array of jets at a standpipe junction point to provide choke point for particle flow control. The flow properties of the extended particle layer are controlled by adjusting the density of the particles above the choke point created by the upper part of the standpipe inside diameter and the top of the distributor. Steam or another fluidization medium may be added to the particles directly above the distributor for this purpose. This invention can also modify the particle or feed injection characteristics by changing the projection of the distributor into the standpipe to adjust the flow area over the choke point and by the use of bottom slides or baffles to change the flow area size and configuration. Location of the distributor at a standpipe junction will also typically allow the placement of the distributor at a lower location in the process which eliminates the need to add vessel height for supplying pressure drop for the particle discharge point. The distributor arrangement also fits compactly into most common standpipe junctions. Thus, the arrangement of this invention solves the problem of inserting an extended array of feed injection points into a fluidized particle contacting process without providing a large amount of clearance or additional vessel height.
