A mini wind farm that you can take wherever you want
Canadian start-up Aurea Technologies has developed a portable wind turbine that shrinks to the size of a water bottle and is designed to deliver reliable, renewable energy on the go.
Intended for use on camping trips or in emergency situations, the Shine turbine can collect up to three phone charges of energy in one hour.
When not in use, its three rotor blades can be folded back to create a compact, torpedo-shaped package about the size of a liter bottle.
Efficiency that makes the difference
The turbine weighs less than 1.4 kg and has a power-to-weight ratio of 29.5 watts per kilogram, which according to Aurea Technologies makes it more efficient than any comparable solar, thermal or hydraulic turbine.
This is due to the “cube relationship between wind and energy,” the company explains. “When the wind speed doubles, energy production increases eight times,” according to Aurea Technologies.
“This, combined with Shine’s highly efficient blades and lightweight design, allows it to produce maximum power with the least weight of any other portable renewable charger.”
While portable solar chargers rely on direct exposure to the sun, the company claims that Shine Turbine works in a wide range of conditions, including wind speeds of 13 to 45km / h and temperatures of freezing to 40 ° C.
It can charge the devices directly or store electricity in the internal battery, which can hold about four full phone charges.
The turbine body and blades are made of weatherproof polycarbonate plastic, while the motor mount and housing are made of aluminum.
It takes about two minutes to set up the Shine turbine using the support pins and cables, according to the manufacturer.
Cheaper wind power
Company founders Cat Adalay and Rachel Carr see the product used for camping, travel and in emergency situations.
“We are offering wind power that fits in the backpack,” Adalay said. “Wind is the second largest producer of clean energy in the world, but most people don’t have direct access to it.”
“As a team of outdoor enthusiasts with a background in science and engineering, we have set out to create a wind power product that gives users the freedom to produce their own clean energy day and night, rain or shine.”
Aurea Technologies was founded in 2017 and is headquartered in Nova Scotia, Canada. The company launched Shine Turbine on the Kickstarter crowdsourcing platform in 2021 before putting it into production.
Other recent innovations in wind energy include the giant offshore Windcatcher, which contains 117 turbines in a vertical grid, and the Papilio wind-powered street lamp.
There is also the O-Wind turbine, designed for high-density urban environments and which won the James Dyson Award in 2018.
