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.

Publishers hated A Wrinkle In Time. And Madeleine L’Engle never forgot the rejections.

What publishers like best is what’s already been done.

Nobody broke through by writing the same things everyone else has written. Don’t let publishers’ small minds limit you!
