I think it’s because the battery industry doesn’t want them.

Think about it. My tablet lasts about a day between charges. Suppose the battery was 5 times better: 5 days between charges.

BUT… a battery’s life is measured in charge/discharge cycles. Basically, how many times it can be charged. So a battery that can go 5 days between charges has a lifespan 5 times longer than that of a one day battery.

That means the battery industry would sell 1/5th the number of batteries. And they certainly don’t want to reduce their sales!

So it’s battery industry’s fault we don’t have better batteries.


This is what he has to say in it that I think pertains to all societies:

“Only to the extent that a society is concerned for its most disadvantaged members, can it be considered truly civil.”

Keep that in mind when some Libertarian, anarcho-capitalist or other right-wing lunatic says that society is supposed to be looking out for the rich and powerful.

Also keep note that the Catholic Church’s definition of “most disadvantaged” does not include LGBTQ or women.
