From the success of 12-inch (30 cm) cylindrical vertical axis (Savonius) type Trinity wind turbine in 2014, Janulus has returned with updated versions of the same in four different sizes, making it more portable, and with switches between horizontal and vertical axis form factors.
While the Trinity 50 wind turbine included an internal 15-watt generator with USB ports and would generate enough power in one hour from a 10 mph (16 km/h) breeze to charge a cell phone, the update gets even better with a convert into a three-blade, horizontal type wind turbine with 50-watt generation that sits alongside three new additions – the Trinity 400, 1000 and 2500, each with larger sizes and increasing levels of power generation with the advanced convert feature.
To the question of portability efficiency, the largest The Trinity 2500, folded up in its cylinder tube carrying case, fits easily in the trunk of an electric car. Standing at 39 inches (100 cm) without its 40-inch tripod stand unfolded, the unit weighs 42 pounds (19 kg) and comes with a 2,500-watt generator that charges a 300,000-mAh lithium-ion battery pack. According to Agust Agustsson, vice president of Janulus, the Trinity 2500, “generates and stores power to run small appliances or to charge your home, electric car and laptop, phone or other gadget.”
The Trinity turbines also share low-cost and practically no set-up requirements and is basically just plug and play. “We come from a country that is completely run on renewable energy,” said Agustsson of his native Iceland. “After spending a few years in the USA we witnessed both the high cost of electricity and the harmful effects of the carbon fuels used to create it. We built our first wind turbine to lower the energy bill and that was the beginning of the development process of the Trinity. We wanted to design a portable product that gave people easy access to sustainable energy.”
In Midwest of the U.S., with its long, cloudy winters and higher than average wind speeds, the minimum speed for the Trinity to work is 4 mph (6.5 km/h) and the settings are converted on vertical once speeds reach 25 mph (40 km/h).
This Trinity turbine comes with a smartphone app to inform the user about the battery levels and to switch the blade settings at will, and also reports about the historical data of wind and energy and electricity generated.
Pledge levels range from US$399 for the Trinity 50, to $5,999 for the Trinity 2500 in the plan to begin shipping by Agustsson by the end of 2016.
