What is a good power source for a personal flying machine?

[Quinton Powell]

Hello,
I am trying to build a personal (one-manned) propulsion system that will allow individuals to fly above the trees, preferably fast, and for long amounts of time. I plan to do so using propellers. The power will need to be plentiful and long lasting. These are some options that I am familiar with: Battery power, Fuel, Solar power, Wind power, Magnetism. What is the best source of power (may include something that I did not mention)? - It must also be light weight and energy dense, or strong enough to carry itself, the operator, and the system.

Invite anyone that you think might have the answer

The two that come to mind are human powered as in

And small gas motor powered as in
