Alternative energy is something I check up on every once in a while
and something I have a keen interest in. However, the usual talk just
focuses on what could be built or achieved in the near future. I'll
share two articles that describe some cool projects already underway
and which should see the light of day very soon.
The first is this one about a
kite-powered freight ship
that utilizes wind power in a novel way to cut down on its fuel
consumption. Apparently, the wind at higher altitudes contains much
more energy than that at sea level so this should provide enough power
to pull a large freighter. From the article:
A kite the size of a football field will provide most of the power for a German heavy freight ship set to launch in December.
I wonder why something like this wasn't attempted in the days of
yore when sailing ships were the primary means of sea transport.
The second is about a
Maglev wind turbine
the construction of which is already underway in central China. These
turbines use permanent magnets that levitate the structure, replacing
the ball bearings that conventional wind turbines use and which require
These turbines are many times more efficient than the standard
offerings, last much longer and require a much smaller area to operate.
They look like something out of a sci-fi movie and I'd love to see one
