Time to experiment with hydrokinetics?

The US crisis is going deeper and deeper. If the Obama Administration will not fix the situation, the dollar will loose his value and the inflation will take over inevitably the whole economy. Even if the government has to fight against such serious problems, the Department of Energy has a mandate to spend $50 million dollars a year for renewable energy researches.

One of this great pilot projects pertains to Ocean Renewable Energy Power Company, LLC, which plans to build the largest ocean-based system of the United Sates. This system works with hydrokinetic turbines, which should to power 50-75 households with their 150 kilowatts. This should improve by 2014 up to 3.2 megawatts.

But there are two questions that make me think twice about this project. They say, this should spare the environment. But if we imagine, how huge this turbines will be, and that the most used material will be metal, we should realise, that this can not be an absolutely environment-friendly system. The corrosion will be inevitable.

Second question. If the power will improve by 2014, that means in 3 years, from 150 kilowatts up to 3.2 megawatts, than the same efficient power, which is gained by a environment damaging coal plant, of 667 megawatts, will be reached in 200 years.

Actually, do we need to invest $50 millions of dollars, yearly, in such long-time projects, or should the US government better concentrate on its economy issues?
