We cannot drill our way out of this oil crisis. Since 2000, oil companies working in the U.S. have doubled the number of wells drilled per year.

Although increased drilling has added new oil to the nation's supply, it has not done so fast enough to offset the terminal decline of existing fields.

We are going to have to import more of our oil. Period.

Yeah, that's it. They are often used as self priming pumps, for example in boats.


Ah ok, those are a kind of centerfugal pumps which have contact between the blades and the housing. I agree for those applications this technology is probably a wash, the vanes undergo a lot of wear forces as is. A non-contact version is designed to last for decades between maintainence rebuilds like they do at the big hydroelectric plants. If you have to replace the pump every 5 years anyhow because one of the vanes breaks off or the set of vanes becomes too worn for solid contact then using Tubercles probably wouldn't do much for your application.

For those interested in this topic the new issue of National Geographic has an article on Biomimetics, including wind turbines using whale style tubercles.

Oh I dunno, at this point I expect the USA taxpayer to be stuck subsidizing airlines for a few years until they cry foul to the Congressmen hard enough.
