RE:RE:New Press Release - Patent Application Filed for an Autonomous, Low-Carbon Footprint, On-Demand Pressurized Hydrogen Production System. No Electricity Required.An aluminum alloy device with an approximate size of 90 mm x 240 mm was thus produced, with an internal volume of 360 cm 3 . The generator weighs approximately 800 g when empty and has around thirty fins with a thickness of 1.5 mm and a dimension of approximately 16 mm x 160 mm. It can be charged with approximately 45 g of metallic powder and approximately 200 ml of water, and it then produces over a period of 80 minutes approximately 45 liters of hydrogen, with a constant flow (after a start-up phase) of the order of 0.5 liters per minute. The maximum fan power is 2.2 W for a maximum rotation speed of 5,000 revolutions per minute, a maximum flow rate of 1.3 m 3 of air per minute and a static air pressure of 156 Pa.
