Perhaps ultrasound is a way to deliver that heat.
I don't think I understand you. Are you saying we should legalize fraud and bank robbery?
I think hoboroadie is saying that we have -already- made fraud and bank robbery legal by the way we allow the system to work (e.g. high-frequency trading and it's associated stock manipulation being allowed - my example, not hobo's)
On the other side of the scale, you have to consider the battery replacement cost. Will his battery pack last 10 years?
There will never be an element called MPAAium, since no element (or particle, for that matter) known to man has a half life that comes even close to the effectuve duration of copyright on "Steamboat Willy".
Protons might be close but they'll probably come up short.
Papyrus is great for reading, but for the ultimate experience you have to carry a clay tablet.
Books -are- great, but they're not the be-all and end-all of carrying words and pictures around. I was just on vacation and took 4 library books and 8 to 10 of my own purchased books with me, basically for no 'physical' cost because my phone, tablet and laptop were coming along anyway. No chance I could forget any of those library books on vacation either, and have to pay for them to be replaced. And of course I could have had 500 books to choose from instead of a dozen or so just as easily.
And another advantage nobody else mentioned yet is that all my devices tracked my place in each book automatically so I could switch devices depending on what was most convenient at the time, and pick up right where I left off.
I'm really looking forward to the day when I'm carrying around my entire library, all the time. I only wish there was a way to replace all my existing paperback books (save for a few sentimental items), with digital copies for cheap (and legal of course).
