Space simulators have come a long way from 1985 when I first played "The Halley Project" on my Commodore 64. It was just as cool as this though (to 15yo me), even though the graphics were limited and it was only our solar system if I remember correctly.
I would definitely pay $60 or more for this. This looks well written and interesting for learning about games I never played back in the day. Bard's tale and Ultima 4 were my first crpg's as a teen in the 80's using my Commodore 64 and 1541 disk drive. I only wish I had the time I had as a teenager to devote to crpg's again.
As far as all electric I agree with you but for hybrids you have some nice choices. For example, the Ford Fusion hybrid and plugin use the same chassis as the Fusion non-hybrids. Some people even remove the hybrid branding:
I had solar pool panels that did fine through hurricane Mathew in west palm beach. They are pvc and plastic I think. I was worried about them flying but they must have been engineered right as far as roof connections (plus the winds remained mostly tropical strength with a few hurricane gusts.)
