nah, she won't wait that long. Next it will be 'grandpa lets do this.I got a pretty keen grand-daughter !
She and I built a few E-bikes together, and when she visits, she always wants to see any changes/ up-dates to the off-grid-solar since last visit.
She is only 11 years old, but pretty interested. I built her a workbench in the shop to suit her height, with all her own tools.
She gave me an Amazon gift card for Christmas with a note "so Papa can get more things for his inventions"
Maybe she will take over operation of the Solar Power Plant once I am gone.
