Wind Turbine Tower Ideas

In this blog post, I will present three simple ideas for reducing the cost and weight of a horizontal axis wind turbine tower. The first idea is to add a streamlined shroud for the tower:

The next idea is more of a question really – why can’t guy wires go inside of the tower?

The last idea is also very simple – if people think lattice towers are ugly, then why not make them look like a tubular tower? One way of doing this is to put a lattice tower inside of a thin-walled, light-weight tubular tower. Another is to cover the lattice with a pourus fabric. This would make the tower look solid, while reducing drag by allowing some wind to penetrate the fabric. And finally, why not cover a lattice tower with slats that can open up like venetian blinds to reduce drag during storm winds:
