a different kind of stuff which has some properties of each.
Isn't the general idea that light has all the properties of each?
Yeah, you need to go on. You've listed 8, which I personally find impressive, but the poll has an option for "More than 15". So you're only half way there.
You'd still need energy. Are you volunteering to hand-crank a trebuchet designed to launch a person at mach 1?
They could use a renewable source of energy, but I wouldn't want to put one too close to a wind farm.
If you make your treb' large enough acceleration at launch can be low enough to be survivable*). Just pack a parachute for your arrival.
Back-of-a-beer-coaster calculations indicate that subsonic speeds won't even get you across the English Channel on a ballistic trajectory. Maybe the parachute would help you glide a little farther, but you'd still need a whole network of trebuchets to get you anywhere you wouldn't rather just walk.
