I love human power But one must take care in understanding human efficiency.... For you efficiency aficionados, a human in a cycling situation is at most ~25% efficient - that's an extremely fit, trained human... That's before mechanical losses

Human power for the developed market, I feel is most suitable in local transport and potentially niche market applications. That is, a human powered home appliances could be costly from a power stand point. Arguably, you would be more fit, but quality of life would likely suffer (I hate stationary cycling, for example - I really enjoy moving through my world ).

Human Power in emerging markets - especially where in areas without a reliable (if any) source of electrical power are amazing. I strongly support enablers. Money isn't really an enabler (ask a sub Saharan country in turmoil) when compared to tools that can power devices like machinery, pumps, small electrical generators, medical devices etc. etc. I saw a human powered rice thresher at Stanford's extreme affordability presentation day - that's exactly the sort of thing I'm thinking of

So that went a bit off topic, but that's me
Cars have not created a new problem. They merely made more urgent the necessity to solve existing ones.
