Hydrobee is a Seattle-based Social Purpose Corporation that has developed a thermo-electric generator called "Firebee" TM, which can turn the heat from biomass stoves into USB charging power for phones, LED lights, internet, and the Jet-Flame blower that improves combustion, saves money and reduces smoke. By connecting with mobile phone networks, Hydrobee's technology enables financing for improved stoves with chimneys that greatly reduce smoke, solving both indoor air pollution and energy poverty for 100 million poor families. Hydrobee's Personal Power Products are recharged by any natural energy source and provide power for battery charging, LED lights, sensors, cameras, and wireless transmitters, making USB power accessible to over 1 billion people living off-grid.
