Using Microwaves To Cook Ballast Stowaways 186
Smivs writes "US researchers say they have developed an effective way to kill unwanted plants and animals that hitch a ride in the ballast waters of cargo vessels. Tests showed that a continuous microwave system was able to remove all marine life within the water tanks. The UN lists 'invasive species' dispersed by ballast water discharges as one of the four main threats to the world's marine ecosystems. For example European zebra mussels (Dreissena polymorpha) have infested more than 40% of the US's inland waterways. Between 1989 and 2000, up to $1B is estimated to have been spent on controlling the spread of the alien invader."

If you've seen pictures of the Fail Boat [flickr.com] around the internet, you might be interested to know the story behind it [wired.com] (link is to printer version). In short, the whole ordeal happened as a result of the requirement that they dump ballast water before entering US waters. The story on Wired covers the accident as well as the salvage operation and is an excellent read.
It appears that this is a dangerous enough process that it was worth eliminating it. That, or they're just trying to cut down on travel time by not having to stop - but that's just the cynic in me talking.

I read articles that make them sound like "rats of the sea" but they do eat them in China so maybe they are good eating (trying to be hopeful).
"The fact they will climb over dams, go on shore into people's swimming pools, burrow into banks, we sure as hell don't need them here," Gabrielson said. "I really believe there's not a damn thing in the world we can do about it."

Talk to anyone who does wreck diving in the Great Lakes. The water used to be really crappy - in fact, in areas it was about as opaque as a glass of lemonade. Or mud. Now it's a LOT clearer.
What we SHOULD be doing is laying removable mesh "beds" for zebra mussels to breed on outside every sewer discharge. Once a good colony is going, remove a portion of the bed each week and grind the mussels up for fertilizer or glue or fish food or whatever.
Henry Ford had the right idea - let people dump anything they want in the river, provided their water intake is downstream of it. After all, if you expect people downstream from you to drink it, you should be prepared to as well ... the zebra mussels are doing a lot of the work that we should be doing, but aren't.
