The basic design for use in a lawn is sets of parallel emitter
lines that run from a supply line to an exhaust line (see drawing on page 76).
Because IR radiation drying is fundamentally different from convection drying, it is necessary to pursue a fuller understanding of the distribution of IR ray from an emitter
which radiates to moist materials, especially involving cases in which each material in the drying chamber receives the radiation uniformly, such as a gas-fired infrared (GIR) dryer Consideration of the designing conditions of IR dryer was important to confirm that the IR radiation was uniformly radiated to the absorbing surface.
To make quantum cryptographic key distribution using a single-photon emitter
a practical reality, one big hurdle has been improving light sources.
Drip irrigation lines, as long as their emitters
deliver 2 gallons per hour or less, are exempt from all watering restrictions.
If the pseudo single-photon emitter
can be replaced with a true one, the setup of a QKD system can be greatly simplified, so that the high level of security guaranteed by the laws of quantum mechanics can be attained.
Moreover, given the rapidly growing economies of India and China, the region is also witnessing the highest growth rate in the infrared emitter
& receiver market.
applications have been proven to significantly increase solar cell efficiencies, but a low-cost, highly scalable process has remained elusive to industry.
The selective emitter
is the first of our applications that we feel will be revenue producing," says Chuck Provini, Natcore President and CEO.

Rain Bird's Sub-Surface Emitter
Tubing retails for under $25 and is available now at major home improvement centers, hardware stores and online retailers.
The rap against drip has been its look - people don't like the sight of black plastic tubing winding between their plants - and its maintenance; emitters
and mini-sprinklers tend to clog.
Customarily, drip tubing is outfitted with emitters
that are snapped into place on the outside of the tubing.
