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.
*) I am not a physicist, this is not travel advice.
When I was a student, I used to hate Sundays. So a flat mate and I devised a system that would rid us of that dreaded day: The 28-hour day: 18 hours awake, 10 hours of sleep. Giving you six days in a week. Don't expect to see much daylight. And find an employer that will allow you to work weird hours. We figured four ten-hour "days".
Don't ask me how it worked out for us, because we never got around to really trying it.
