I’m attending the wind energy and hydrogen conference today and tomorrow. I’ll let you know if I see anything interesting.

Hope it’s worth the money then!

It was free because I’m not presenting. So I hope it’s worth more than the money!

Stuff I’m interesed in, is not necessarily what other forumites are interested in. There’s a lot of companies advertising offshore cranes for erection of offshore structures .

I rather like the one person automatic lift, open on all four sides, for getting to the top of a wind turbine. So much better than the interminable climbing of steel ladders especially when laden with maintenance components. 80,000 have already been installed worldwide.

Neutrino will be interested in the use of lidar on drones that is currently being used to inspect the leading edges of wind turbine blades. Each costs $35,000. Unladen it wll fly for 50 minutes on a single charge. Laden with Lidar and camera it can fly for 30 minutes.

I looked at the top bracket wind and weather prediction software system for wind turbines. I wasn’t enormously impressed because it couldn’t predict tornadoes or microbursts. But it does integrate weather station information mounted on each wind turbine with regional weather predictions for the purposes of deciding optimum blade angle and for protection of wind turbines from from extreme events.

The hydrogen stuff so far has mostly been efficient electrolysis systems. I personally prefer extraction of hydrogen from methane and ammonia, but that isn’t showcased here.

There is also someone here advertising expertise in environmental impact on such animals as frogs. But really, the direct effect on frogs of offshore wind turbines is pretty minor.

Apologies for the thread title – autocorrect.

Wonder what the covfefe of it will be like.

One thing I’d like to see is moving the big generator to the base of the tower and drive it via long shafts. If you use two concentric shafts driven in opposite directions, that would cancel the torque effect that you get from just driving a single shaft. Make the shafts have the same rotational moment of inertia, etc.
But I guess the engineering mobs have already thought of that and decided that it wasn’t the best way to go for some reason.

I thought that was in Aug but maybe I’m thinking of something else. Thanks in advance for keeping us informed.

Bad design

They need the type where the blades are vertical aerofoil that curve around to catch the wind from any direction – these designs don’t need complicated software to catch the wind the design of the thing catches any wind

Oh yes

NO fibreglass. They should make the blades from aluminium, it takes lightning strikes no problem and is easily recycled.

These types don’t kill birds
