ice-vest/chest personal cooling unit. Tinkering conceptually, at least ;-). But the ice vest is a symptom of a much larger climate concern.
Those with more power than I to affect change need to address it: Congress should mandate personal ice vests for everyone!
No, not really. Actually (or, maybe in addition to?), they need to adopt the economists' simple, one-page answer to climate change: tax carbon emissions.
Henry Jacoby, an economist at MIT's business school, says the one thing you need to do to solve the problem is to tax fossil fuels in proportion to the amount of carbon they release. That would make coal, oil and natural gas more expensive. That's it; that's the whole plan.
So simple but yet so effective. Then again, I'd probably want to add a phase in period of 10 years so as not to shock the economy too badly. Otherwise... let's get on this plan, Congress, pronto!
(Oh, and call me if you want more detailed plans regarding my the hybrid vest/chest air conditioner.)
