Most surfers don't drive those old vans and cars. If you want to buy a vehicle for surfing, the best thing to do is buy a modernish van with no windows (stops people breaking in).

QuoteI'd be careful with that one Chris, the beaten up VW Campers & Beetles aren't the most efficient vehicles around (31mpg, which is pretty similar to a land rover discovery 3!), plus they don't have catalytic convertors or complex Engine management sytems and as such you will probably find the emissions are far worst than the Disco.

I was talking about people who actually surf, not those who just drive around with surfboards on the roof!

I have a sneaking suspicion that the Wave Hub and generators will make no discrnable difference....but do not have the mathematical skill or scientific background to back up my suspicions. I DO remember wave experiments in Physics at school, and how waves tend to reform after passing an object in the liquid though

Here is the report that was done on the potential wave impacts.

It goes through Water Levels, Offshore Wave Conditions, Recorded Wave Data, Wave Power, Impacts of Wave Hub on Wave Climate, Wave Modelling by Others, Impacts of Wave Hub on Tidal Streams and Currents and Impacts of Wave Hub on Sediment Regime.

It is far too technical for me to understand. But I am sure one of you will have the ability to comprehend it.

You may also remember the laws of thermodynamics, which would suggest that the energy once taken away will not reappear. There may also be issues with diffraction of the waves too.

If you're interested in waves and how they are formed, this Book is good.

I'm sure the energy companies would be hugely delighted if they could take 5% of the energy out the cornish coast! Not likely in my opinion as the energy is so massive. Anyone who thinks this wave hub is going to make a discernable difference to wave heights massively underestimate how much energy is in our seas. And anyway this is a trial site not a commercial setup, what are you saying? give up on wave energy without trying, how forward thinking is that? And before you start going on about putting it off of the Scottish coast, there are a couple of reasons why St Ives bay was chosen above Scotland: -

The eletrical infrastructure is already in place, remember Hayle once homed one of the largest coal power stations in the country (At the time), to put in the infrastructure which would include the following in Scotland: - 11/33kV Substation, 33kV/132kV Substation and the grid connections would cost tens of millions.

The energy in the sea off scotland is so great it would rip any structures to pieces.

Just had a read of the report and the analysis that has been put toghether is totally worst case, in the modelling it is assumed that the wave hub will take out 100% of the wave energy in a 10km^2 area, i.e. the swell on one side could be 4m and the other side would be zero! The only way that could be achieved would be to build a dam wall there!

I just dont want to see the wave energy a wave hub could save (and we as
surfers loose) to be spent on something as frivellous as lighting up future
casinos.

The wave hub should be a small part of a much further wide-ranging review
of energy usage/policy.

Me, you just don't get it do you?
Wave hub is a platform to enable trials of off shore tidal generation, not a major power station. One of the things that will come out of the trial will be the effect (if any) on on shore conditions. And as to the bit about casinos, what the hell are you on!

Think I can see why you chose Me as a name, because all you seem to care about is Me Me ME!

CK - Try reading AND understanding my post(s), and your questions will answer themselves.

I just think that 'wave fronts' (or whatever the technical term is) are hellish wide, and that the actual 'gizmos' will be comparatively minute.

I suspect no one will notice any difference in the surfing.

..and like CK says, its only a trial anyway. Results can be measured, and representations made IF the surfing is affected.

Case of "Wait and see" isn't it?....or are you saying that the trial should not go ahead IN CASE it affects the surfing?

Graham.

Me, I have read and undertood your posts, you and those that don't want it have taken a worst case scenario and exagerated it to an even worst case scenario, to attemnpt to gain support for your point of view. I'm sick and tired of people in this county complaining to the extent that we've missed so many boats its ridiculous.
The wave hub could be something that leads to the development of a MEANINGFUL industry that the county needs.
The worst case scenario has been put forward and any effect will be less than that by a long shot due to the fact that the main assumption in the research was that 100% of the energy over a 10km^2 area will be taken out of the sea, which ain't ever going to happen.
So we have got an effect (Which is pretty insignificant) for a worst case scenario, now lets see how insignificant the effect with a real trial will be.

Please tell me where I said I don't want it?

How do you know what the affects will be and what the worse case scenario is, when noone to this day has any idea?

I guess people (like me) have assumed you didn't want it as you linked to the A1Surf objection form to put in regarding the proposal.

The objecion form is just that, it does not mean people are against the wave hub in principle, just the planning (or lack of) behind it. This is also my viewpoint, in that I believe the planning process is flawed.
