Domestic Water Generator

The domestic market holds immense potential for this technology, as quoted, "It might not be glamorous, but it packs a punch." This concept features concentric thin-walled tubes coated with self-assembling NBD surface and is driven by either a PC fan or natural wind. Assuming 75cfm fan usage, the effective area is approximately 3 square meters based on 150cfm requirement, providing up to 9 liters per hour from a 120mm diameter tube in a windy spot. This translates to potentially 50 liters of water a day at 70% relative humidity and standard temperature. At 5 watts for 75cfm fan usage, the cost per liter is less than half that of mains water (GBP0.00008 vs GBP0.0022), making it a cost-effective alternative even at lower efficiency levels.
