Icing is a problem for wind turbines, with some measurements reporting as much as 20% loss of efficiency due to the simple effect of icing on blades. (A 2011 article in Cold Regions Science and Technology takes a deep dive into many of the then-known – and unknown – variables that have been fueling the concern to de-ice wind turbine blades.) Heating the blades seems like an obvious solution but straight heat without any data to back it up is not as wise as it sounds in cold-climate conditions – so some companies have been turning to data and “algorithms” to back up their solutions. For blades where a proprietary heating solution isn’t available, or simply as a backup measure, de-icing the blades is the way to go. This has been done before with helicopters, which are both costly and pose their own risks. Latvian drone-solution company Aerones have been using their 170 lb. drone capable of a 400 lb. payload that has a tethered cable for both power and delivery of liquid solution to hard-to-reach places, making quick work of the de-icing process.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
