Can microwaves carry a power of around 200hp........ theoretically?? and also converging it by the help of a parabolic antenna at a point around say 500 feet above the source???

Microwaves can carry any power... It's limited by

- The availability and price of the source. Magnetrons for ovens deliver 300W at 2.45GHz for some $ and can be summed. Expensive sources achieve MW.

- The protection of people, animals, plants...

- Real physical limits like air ionization wont' be attained easily in open space. It was attained in the waveguide feeding radar antennas, with several MW in few cm², where dry nitrogen at high pressure improves over air.

 

170m above the source: that's a matter of diffraction "only", that is, of wavelength and antenna diameter, and of how concentrated the focus must be. Have a look at "diffraction" for lenses or telescope mirrors or antennas; the likely answer is "antenna too big for your taste".
