This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

Blade Runless?
A Madrid-based company have invented a source of wind power without blades (https://www.theguardian.com/environment/2021/mar/16/good-vibrations-bladeless-turbines-could-bring-wind-power-to-your-home). The 3 metre high 'Vortex Bladeless' towers, just vibrate in the wind to generate electricity (like these humanoid balloon figures you sometimes see at sporting events?). The Vortex Bladeless has have already attracted the attention of Norway's Equinor Company. Clearly, adoption of bladeless wind power devices, would be good news for bird populations. Seeing these 'skyvibrators' wriggling on the hillsides might, however, be a bit strange at first.
