How will this respond to extended time in seawater, barnacles, seaweed, etc.? I think you would need some sort of option to bring them ashore for maintenance. I imagine barnacles would significantly reduce the efficiency of the shape, etc. Also, since the turbine is going super slow, would it be possible for barnacles to attach to the turbine itself?

Thank you for this very interesting question. You are absolutely correct when you describe marine growth - bio fouling - detuning the performance of the turbine. We at Tidal Energy Pty Ltd unlike some of our competitors DO NOT use anti fouling chemicals painted onto the turbine. We use a Patented electronic acoustic device that repels the marine organisms without harming or polluting the sensitive eco systems where our turbines are installed.

There are numerous means to keep "bio fouling" from de-tuning the turbine. All of which require NO dangerous coatings. These methods are part of our propriety intellectual property that we do not share here. I am sure that if you put your mind to it you can think of several methods that would work. Thank you for your comments and the interest you have shown in this world leading if not world best water turbine technology.

Thank you for the kind remarks. We are organising a public offer in the not to distant future. I will shoot you a note when it is ready to go. OK ?!

All collected data to date has shown zero fish kills so it is difficult to mount an arguement that there are consequences.

The turbine turns incredibly slow - so slow, even the sickest guppy would find it easy to avoid.

The question I would pose is where do we get our energy from - the sun does not always shine and does not have the energy density nor does the wind blow 24/7.

Water in tides moving at 8 knots has more energy then winf at 200 mph.

Food for thought ????

How would this fare in an ecologically sensitive coastal country? I am from Ecuador and am looking at energy alternatives for the near future.

My pet dolphin was killed in one of these.

if it would be possible to convert all the tidal energy - it would have a major impact on the environment. so let's stay realistic and first ask what kind of energy transformation and how much energy can be transformed without leaving a footprint that's negative for the environment which would have a negative impact on humans.

[motionapplied]

the first focus should be in reducing the huge amount of wasting energy.

@JBC814 For every windmill about 1-2birds are killed each year. To put that into context about 57 million birds die each year fron collision with vehicles, 1.25millin from collisions with tall buildings, 97.5 million from collision with plate glass and the ordinary pet cat kills about 100 million birds each year. All of this in the US only! Are you maybe advocating genocide of kittens and cats aswell? And ONE 1.8MW windmill can, in a good location, generate electricity for over 1000 homes..

our governments need to introduce these world savers

[nitronovice]

has marine life safety be thought of in this design? it seems like it wold be a hazard to anything that could swim near or into it.
