Canadian start-up Aurea Technologies has developed a novel new way to charge your electronic devices when away from civilisation - a portable wind turbine.
The Shine Turbine compacts down to the size of a water bottle but can provide reliable, renewable energy anywhere.
Intended for use during camping trips or in emergency situations, the Shine Turbine can collect as much as three phone charges worth of power in an hour - making it more powerful than portable solar charges and usable in cloudy and wet conditions.
The turbine weighs less than 1.4 kilograms and has a power-to-weight ratio of 29.5 watts per kilogram, making it more efficient than current iterations of solar panels, thermoelectric stoves or water turbines.
"We're offering wind power that fits in your backpack," said Cat Adalay, CEO and Founder of Aurea Technologies. "Wind is the second-largest producer of clean energy in the world, yet most people don't have direct access to it.
"As a team of outdoor enthusiasts with backgrounds in science and engineering, we set out to create a wind power product that gives users the freedom to produce their own clean energy day or night, rain, cloud, or shine."
The Shine Turbine has the battery capacity for four full phone charges, so it is great for sharing power or keeping multiple devices charged, multiple day camping trips, or charging power-intensive portable devices. Shine's patent-pending high-efficiency blades and lightweight design allow it to produce an output of 13.3 watts per pound. This is a superior power-to-weight ratio compared to other handheld portable renewable products such as solar panels, thermoelectric stoves, and water turbines.
The turbine's body and blades are made from weatherproof polycarbonate plastic while the mount and motor enclosure are made from aluminium.
