Your math is wrong. 98J/s = 98 watts. 98 watts * 24 hours = 2.35 KwH, not 8467.2 as you claim. Your calculations are off by 3 orders of magnitude, which gets to a core problem with wave power, and most renewables: Energy density. The energy densities involved are too low to be economically feasible to use.
We have a lot of work to do to overcome these fundamental limitations, otherwise, be prepared to have an enormous amount of these generators everywhere along the coast. Nuclear power is very attractive compared to this.

Hello Pablo,
what would be the behaviour of sea inhabitants to wave farms?

There are many technologies in development. The one that I referenced is called Seadog (http://www.inri.us).

Hello Pablo,
Could you please direct me to more information on the following topic you quoted ” -He also informed me that the same technology is being used to pump seawater uphill into large storage tanks. When electricity is needed the water is run back downhill and through a turbine generator.”
Thank you very much,
Victor
