Many areas in the world are remote, windy and have no fossil fuels.
According to the video on their site, this generates twice the power of regular wind turbines. How does the cost compare? Currently, wind is more expensive than solar. All clean sources are more expensive than dirty, in dollars anyway.
If it works, will companies and governments invest?
I wonder how they will keep airplanes from hitting the tethers as they might be hard to see. It would be good if they could put a net on both ends of the tunnel to prevent bird deaths. Some birds fly that high.
I also wonder about the vector of force on the tethers at such high angles of elevation. As wind speed increases, the altitude of the turbine would decrease leaving the leeward tethers hanging slack. But I'm sure they have thought this out.
I think this is quite an ingenious new direction to take wind turbines as there is a lot of energy to be harvested from winds at high altitudes. If this technology proves itself it could be a real breakthrough for places where there is not a lot of ground space for turbines, but there is still quite a bit of wind. I will be curious to see how it fares in the Alaska test.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
