The new water purifier will be a portable, low-power system that will simplify the process of bringing clean water to rural areas. The purifier will work by boiling the water until it turns to steam, which will then be compressed back to liquid water in a pure, distilled form. A hose attached to the device will be inserted into the water - be it ocean water, a mud puddle or even liquid from a chemical waste site. The water will be drawn into the purifier and heated to its boiling...
A paper strip test will be able to detect E. coli in water and indicate whether the water is safe for swimming. The strips will be coated with chemicals that change color in the presence of E. coli. They will be printed using conventional inkjet printer technology. Results will be returned within 30 minutes, with different colors representing the different concentrations and types of bacteria in the sample. It could be possible to create strips capable of indicating water...
The idea is to launch floating islands in lakes in an effort to improve water conditions and restore natural habitats. The islands will be made up of non-toxic recycled plastics injected with an inert polyurethane foam for buoyancy, and will act as floating treatment wetlands. The islands will mimic a concentrated wetland, eliminating algae blooms and problematic nutrients while encouraging bird and insect populations.
