Someone I know who runs a nonprofit related to helping remote fishing villages and the like in his Asian country, claims supercapacitors are less than 5 years away.

"If" that is true, then a time-shifting bank of such supercapacitors could presumably solve the very real issues you raise.

What do remote villages in Asia have to do with supercapacitors?

[patrickgzill]

He is someone who works full time in researching alternative energy solutions for those fishing villages.

Wind or solar solutions that he specifies have to be rugged and easily maintained without access to fancy tools, and batteries can wear out quickly in high-temperature environments.

Thus he has been researching supercapacitors.

Supercapacitors are less than five years away, and have been that way for at least ten years now.
