Hybrid cargo ship

Cool! It can cut 20% of the fuel bill. Impressive!

I am all for efficiency improvements, but inventions like this, unfortunately, don't end up helping the environment. The end result is they just send more boats and increase their earnings with the increased efficiency and the same amount of oil is used. So net impact on the environment is more or less the same.

We ultimately need technologies that shift us away from CO2 producing fuel sources.

I agree, but change has to be incremental. Its not likely that existing cargo ships will be going away anytime soon, so this sort of retrofitting at least replaces the oil that would otherwise be burned with wind power.

Right - but my point is that this change isn't even incremental. In other words, the same amount of oil ends up being used because they send more ships. The only change is an increase in efficency - i.e. it is like getting a better more fuel effficient motor. Only good if it is used the same amount as before.

I think this is actually a response to market realities. The good one thing Bush (quite accidentally) did was to take Iraqi oil offline just as worldwide demand was growing. This has driven the price of fuel through the roof. Ergo, you see things like this. As long as the price of oil stays high, we are likely to see more and more innovation to improve efficiency. I think that is a good thing. Government action is good, but the presence of economic necessity is a much better stimulus to innovation.
