What about plug in electric cars (i.e. Chevy Volt)? Makes stationary power portable. Also, most city subway trains run on electricity too.

Amen brother. Back in 1995 my standalone databasing application was 10x faster than the web based crap we use today. Even the best web based applications are excruciatingly slow compared to a the same desktop app. I agree that there's some app's well suited for web, but large databases, file repositories, etc are hindered by slow connections, rendering, etc.

Years ago I took my old floppies, recorded them to disk images, and got rid of floppies forever. Why not do the same for these weird formats? Unless you're constantly receiving new tapes/disks, get a reader from Ebay, image your files, then resell the reader. Repeat for other formats.
