New way to save the Earth

harvest tidal energy..

billions of gallons of water flowing day in and day out could power simple turbine arrays..

oh wait, that makes way too much sense, and doesn't allow oil corps to make cash..

Technical Challenges
For ocean current energy to be utilized successfully at a commercial scale, a number of potential technical challenges need to be addressed, including:

•avoidance of cavitations (bubble formation);
•prevention of marine growth buildup;
•reliability (since maintenance costs are potentially high); and
•corrosion resistance.
Environmental Considerations
Ocean current energy technology project planning will need to consider species protection (including fish and marine mammals) from injury from turning turbine blades. Consideration of shipping routes and present recreational uses, such as fishing and diving, will be required when considering siting of the turbines. Other considerations include risks from slowing the current flow by extracting energy. Local effects, such as changes of estuary mixing resulting in temperature and salinity modifications, might affect species in estuaries.
