I've had an idea that I was wondering if it would be possible.
I came up with this idea when thinking about local computer backups. Companies such as IoSafe make hard drives which are water & fireproof, however I'd be willing to bet that a good electrical surge would take one out.
Would it be possible to isolate a hard drive (or SSD), electricially, simply using solar cells for power and fiber optic for communications?
You'd have a light source which would power up the solar cells, which would power the HDD/SSD. You'd have a fiber optic connection for data.
In theory it would be very isolated from outside elements.
Does such a device exist? Is there a reason why not?
