Today marks Global Wind Day (I know what you're thinking, and no not that kind of wind)!
We’ve seen the bladeless ‘skybrator’, but have you heard about vertical-axis wind turbines (VAWT)?
They’ll be tricky to scale at the moment - they’ll need more space (due to needing more individual VAWTs) and materials in order to produce the same amount of energy as horizontal-axis wind turbines (HAWT) - these being the wind turbines we all know and recognise already.
However, they’re handy for residential or small-scale projects. Their size means they can be fitted in cities and on rooftops - something the HAWT’s can’t do.
Here’s a handy 60 sec video that tells you more:
