i had a thought walking through the rain: what we need to deal with flooding issues are elephants. if you just let an elephant walk through the streets it would suck all the water up and voila...

....except there are some problems. it's too cold for elephants, and that's not clean water, and it has to find it's way back out eventually.

so, robot elephants. seriously. this is the future of flood control.

i mean, we could maybe deal with the weather issue by genetically engineering mammoths, but it's still not humane to have them out lapping up water on the street.
