Abstract: A solar powered highly efficient modular and scalable desalinization plant, using a typical thermal evaporation desalination unit, hydrogen fuel cells, heat-exchangers, hydride-tanks with a control-manifold with input/output selector, hydrogen generation and a solar power source providing low-cost per unit of potable water and low maintenance. Hydrogen Storage and a fuel cell providing combined heat and power enables the plant to operate continuously.

Abstract: This invention creates an electronic “document authentication chain” providing authentication capability of certain document characteristics. Certain operational scenarios require that a primary or third party can prove the section inclusion and section “inclusion order” of document entries. A minimally intrusive and chained watermarking technique is invented facilitating the authentication of these document characteristics using asymmetric or symmetric key digital signatures.

Abstract: A wind chime, which includes an annular array of chimes, a superior horizontal wind baffle positioned above the chime array, a striker, positioned below the wind baffle. The wind baffle is positioned beneath a commercially available hummingbird feeder. Hummingbirds landing, leaving, and hovering at the feeder produce air currents which act on the wind baffle. This action moves the striker into the chimes, which give a tonal response.
