Beth Ann's Blog for Eco-Geeks

You might have noticed that I haven't posted here since August. I think I've exhausted the subject of writing, so I've been rethinking what to do with this space. Meantime, Beth Ann (teen science whiz and costar of my Possessed Mystery Series), asked if she could use my blog to save the earth. Could I say no? Here's her first entry.

Wind Energy Turned On Its Side
by Beth Ann Lee

Last summer, London's Olympic Park included 7 vertical axis wind turbines. Here's a photo.

They look pretty classy, don't they? Less offensive than a lot of cables strung all over a city.

A vertical axis turbine can catch wind from any direction. They're more efficient than a standard wind turbine because they don't require a minimum wind speed or power to start. They're also quieter. These could easily be used on roadways to offset or fulfill the power needs of streetlamps and  traffic lights, and on bridges for a de-icing grid. One turbine can provide up to 7500 kWh per year, making them a viable power source for home rooftops.
