A bit off topic, but cool nonetheless. In Discover Magazine’s current issue the article Wave Energy: Can a mechanical snake that surfs the ocean squeeze enough watts from water? is something all renewable energy enthusiasts should read. I love reading about innovative technology that can decrease the dependency on fossil fuels. Wind energy is the type I’m most familiar with. I have read a few of Paul Gipe’s books (Wind Energy Basics: A Guide to Small and Micro Wind Systems, Wind Power: Renewable Energy for Home, Farm and Business) and some books from Hugh Piggott (Windpower Workshop, Small Wind Systems for Rural Energy Services, and actual plans to build your own windmill), for those who want some really interesting reading on wind power. Anyway, I have never heard of gathering energy from ocean waves. The amount of energy that can be gathered is very substantial. With all of the various methods of getting energy (solar, wind, water dams and turbines, and now ocean waves) why do we still use oil/coal/nuclear. One of the major drawbacks to renewable energies is storage. Batteries used in renewable energy storage are composed of some of the most toxic elements like lead. One of the things I would propose is that we use hydrogen as a storage device and then use a hydrogen fuel cell to convert back to electricity. Hydrogen should be the next energy medium for our economy. No one owns hydrogen. It’s easily decomposed from water using any of the aforementioned renewable sources. Although hydrogen is explosive (gas is flammable and it can/is stored properly in vehicles), it can provide the least environmental impact. It would actually provide no environmental impact. No lead acid batteries to store energy, no more fossil fuels, no more pollution, global warming, etc… I really hope as a society that we open up our minds to these possibilities. In the short term it is expensive since these technologies aren’t as popular and do not have the same amount of money invested in it. It’s only to our benefit in the long term to invest in renewable energy. Oil/coal isn’t going to get any cheaper.
