Reddit reviews Shaluoman Farad Capacitor 2.7V 500F 35X60MM Super Capacitor with Protection Board

great write up. there are some shortcomings in the authors system which he described quite honestly but offered little to no alternatives. let me quickly re-iterate those downsides so i can explain my solutions.

typical pv solar cells have a life cycle of only about a decade or two. lead-acid batteries have a similar life span and have the added fuckery of being nigh impossible to dispose of cleanly when they are spent. combine this with the diesel used to run backups, this personal grid is almost entirely reliant on the national grid for fuel and spare part deliveries. additionally, there are not enough trees on hawaii to rely on wood burning for warmth indefinitely. the author admits this system (including spare parts and backups) only has a life span of about 30-50 years which is a fairly long time. but if you plan on your grandkids surviving, they wont be able to benefit from this type of personal grid set up.

solutions:

atmospheric electricity can be harvested, used and stored with parts almost entirely built from scrap and it requires only 4 or 5 different parts. all this requires is an antenna that is as long as possible with as much surface area as possible as high up in the air (ideally above the treeline) as possible connected to a grounding rod that ideally goes as deep into the earth as the antenna is high with a motor/generator in between. the ionosphere of the earth itself powers the motor day AND night, rain OR shine(in fact voltage increases during storms). alls else you need is a capacitor/battery bank for energy storage. meaning the system has a lifecycle as long as your batteries/capacitors last and as long as the earth has an ionosphere which can be MUCH longer than 30-50 years if you use saltwater batteries and graphite/graphene capacitors, both of which can be easily built at home using fairly common materials.

robert murray smith has been working on simple yet powerful DIY acid-free battery/capacitor tech for years and is WELL worth looking into. he has a company that sells conductive ink which you can use to make capacitors and batteries out of paper. if you browse his youtube channel you can find out how to make conductive ink, capacitors and batteries by yourself at home

edit: if you dont care about pollution, there will probably be a fuck ton of useless pennies everywhere after the fall which can be used with nickel washers to make battery cells as well

Supercaps are on the market, but fairly expensive. They are voltage sensitive, and need charge balance control. 16V kit sample
