Portable turbine provides a "stream" of power for charging devices
To cover all bases though, you may soon also be able to take a portable water turbine with you to harness the flow of a river or stream.
We covered Enomad earlier this year when it showed off a portable water turbine concept for charging mobile devices at SXSW. Now the company is back with a refined version that is ready to be commercialized.
The Estream, as it is now called, isn't the first portable water-turbine charger. Both the HydroBee and the Blue Freedom offer similar functionality and portability, although, the Estream looks to pack away into perhaps the handiest unit for carrying and has a bigger battery capacity than both.
The device is made largely out of ABS and polycarbonate. It measures 24.5 x 6.5 cm (9.7 x 2.5 in) when packed away and, once its turbine blades are folded out, they have a diameter of 21 cm (8.3 in). It weighs in at a very manageable 800 g (1.8 lb).
