Can I fly ?
Of course it is possible, with ultralight airplanes or with motorized kites.
Whether a flying machine with movable wings can be developed, with which I have enough power to fly thanks to my exoskeleton, will be a question of research and development work. After all, major aircraft manufacturers are already working on researching such flying machines.

To stay on the basis of technology that exists today: A paraglide with a propeller on its back will fly, corresponding inventions have already been presented on television. However, there is always a gasoline engine with it. You can buy such devices today as "backpacks":

Nevertheless, I would still be a little cautious at this point, at least at the beginning in the transition phase, because if too many fliers are flying around in the air, we will have to find a regulation so that the many flying objects do not collide. However, this limitation does not have its reason in the zero point energy.
Water also belongs to nature. Not only on the land and in the air I can move, but also under water. Riding a boat is nothing special, I don't want to talk about that, because you can do that already today. Powering the ship's engine with zero point energy is nice, but not a particularly surprising idea. Sailboats are also ships that are powered sustainably with clean energy - even if zero point energy has the advantage over it, that we don't get stuck in a calm.
