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.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
