Wow, I didn’t know that seagrass has pollen, seeds and all the stuff needed for plants to sexually reproduce on land.
It might be extremely handy for the conservation effort, because you don’t need genetic engineering to spread useful traits then.
I hope they succeed. :)
Oh, indeed, that’s a common problem with them. :) You can find them here:
Solar is expensive.
At this point, definitely no. At present, you can buy panels at 0.12 € / W if you choose where to shop. (This autumn, I’m considering adding 10 panels, 380 W each, for a price of 46 € each - in fence configuration, so minimum installation cost too). It’s the cheapest source of power, if you have sunlight (unfortunately, in winter I don’t have a lot, too far north).
Batteries do cost a fair bit.
As for resilience, panels are fairly resilient. A panel punctured by some shrapnel will keep working at reduced power, unless it hit the junction box. Living in a peaceful area, I didn’t need a missile to find out - I found out using a storm which made plywood fly at considerable speed.
My preference has become Maximum Solar. They work with button and LCD control. It ain’t convenient but I reprogram them only twice a year - when transitioning between summer (hot, energy surplus, preserve batteries by not charging them fully) and winter configurations (cold, energy deficit, fill batteries to the maximum). I’ve thought about automating that, but didn’t bother.
I never let my energy devices onto the Internet. The house controller - a Raspberry Pi - is allowed when I wire it to the router using an ethernet cable.
If I worked at the company which did the cyberattack, I would fear both civil liability and prosecution.
Additional note: per UK. :) The predicted effect, either in meters or millions of cars, is if the UK inhabitants currently eating a high-meat diet switched to a low-meat diet.
