Abstract:
1. A solar powered water purification and heating/cooling canteen comprising: a container adapted to hold a fluid having a reservoir, an inlet and an outlet, said reservoir being made of a clear liner, said clear liner being adapted to allow UV rays from said UV LED lights to enter said reservoir; UV LED lights around said reservoir adapted to kill any bacteria from fluid in said reservoir; a thermoelectric plate positioned at the bottom of said reservoir adapted for heating and/or cooling the fluid in said reservoir; a solar power panel positioned on the outside of said container adapted to power said UV LED lights and said thermoelectric plate; a charcoal filter layer adapted to filter fluid as it enters said inlet; a one way flow device between said charcoal filter layer and said reservoir adapted to allow water to flow from said charcoal filter layer to said reservoir but not from said reservoir to said charcoal filter layer; said one way flow device being selected from the group consisting of: a semi-permeable membrane adapted to allow one way water flow from said charcoal filter layer into said reservoir; and a check valve between said charcoal filter layer and said reservoir adapted to allow one way water flow from said charcoal filter layer into said reservoir; a switch plate adapted for controlling the UV LED lights and/or the cooling/warming of said thermoelectric plate; a supercapacitor adapted for storing energy from said solar power panel; a cap adapted to seal said inlet; a zippered top adapted for accessing said charcoal filter layer; and a drinking tube connected to said outlet including a water exit valve adapted to control the water exiting said drinking tube; said water exit valve being in communication with said switch plate, whereby said water exit valve may be adapted to keep the user from drawing the water before it has been sufficiently irradiated with UV light.
