Sustainable Technologies Category Winner, "Create the Future" 2007 Design Contest

(Winner of an HP Workstation)   LEDTRICITY™ Ted Bristow Creative Electric Kailua Kona, HI LEDTRICITY™ uses a combination of various electrical principles, unique wiring circuits, and state-of-the-art components to produce a safe, low-voltage/current output. The illumination of LEDs (Light Emitting Diodes) using the LEDTRICITY system results in the ability to use extremely long, inexpensive wires to illuminate hundreds to thousands of LEDs.

Unique DNA Signature Identifies Organism’s Species

Unique genetic markers called oligonucleotides can provide swift identification of a known organism or rule out an organism from known genomes. This software technology provides a way to generate thousands of such markers and provides a searchable database of chromosomal sequences for over 100 pathogens and near-neighbor organisms, unique plasmid sequences, and markers for virulence and antibioticresistant genes in a platform-independent format. Using the technology, the existing database can be extended to any DNA-based organisms. With as few as 20 DNA fragments, the system can achieve a 99% confidence of no false negatives against a library of samples.

Finger Seals Replace Brush or Labyrinth Seals

Finger seals are non-contact fluid seals similar in purpose to labyrinth or brush seals in that they act as a barrier between two areas of the same or different pressures, but allow a rotating shaft to penetrate through them from one side to the other. Applications include sealing rotating parts in turbine engines, pumps, rotating air motors, or other applications where a shaft needs to be sealed against incursion or excursion of oil, air, water, or other gases or fluids.
