I took a #LEGO Wind Turbine to an actual wind farm. It didn’t go well. So we tried something crazier… || This video was created in partnership with Bill Gates, inspired by his new book “How to Avoid a Climate Disaster.” Find out more here: http://gatesnot.es/2ZAebRP

Wind power gets a lot of flack, far more than its #renewableenergy sisters hydroelectric, geothermal, or solar. What is it about #windenergy that’s so hard for people to grasp? In this video I build my own #windturbine and try out my creation at the Alta Wind Energy Center with spectacularly terrible results. Then I hit up my friend @Nick Uhas to see if we can build our own wind tunnel and try this again. You’ll have to see what happens…

How is electricity measured?
Understanding watts, megawatts, kilowatt-hours, and more. Watts are a measurement of power, describing the rate at which electricity is being used at a specific moment. For example, a 15-watt LED light bulb draws 15 watts of electricity at any moment when turned on.
What makes the wind blow?
Wind has been whirling around the world since long before we’ve been here to notice it. It howls outside your window, toppling trees and stirring up storms that could snatch your hat right off of your head and send it flying through the air.
US Wind Turbine Database (this is amazing!)
The data were created by combining publicly available data sets from the Federal Aviation Administration (FAA), USGS WindFarm data from a prior effort, online sources, and data privately held by AWEA and LBNL. The locations of all turbines were visually verified to within 10 meters using high-resolution imagery. Technical specifications of the turbines are based on the make and model and other information collected.
Nanocoatings and other future deicing systems
The usual de-icing sprays for aircraft and other applications use ethylene glycol, a chemical that is environmentally unfriendly. Airlines don’t like to use active heating, both for cost and safety reasons. Varanasi and other researchers have investigated the use of superhydrophobic surfaces to prevent icing passively, but those coatings can be impaired by frost formation, which tends to fill the microscopic textures that give the surface its ice-shedding properties.
Wanna build your own wind tunnel? Try Baal’s Wind Tunnel. (This is the design we started with)
This is the Baals Wind Tunnel. It can be built for under $200 and can get about 30 mph in the test section (where the plane is).
