Nope. Energy will be lost in the process due to friction among other things. People have tried for millennia to make a device similar to what your saying. No luck so far.
Hypothetically speaking, if you did use a leaf blower to power a wind turbine that generated 100 per cent or more of the electricity needed for powering the leaf blower, then yes you would have created a perpetual motion device. <br />
To do so you would need to invent both a motor that was 100 per cent efficient and an electrical generator that was 100 per cent efficient. Either invention would make you rich from the patent rights, since the most efficient electric motors and electric generators are only about 90 per cent efficient. You would also win one or more Nobel prizes with such an invention. I wish you especially in inventing an electric generating process that is more efficient. Imagine the wonderful environmental impact if with one invention you increased the world's supply of hydroelectricity by 10 per cent.
I had a neighbor this winter use his leaf blower as a snow blower to clean off his driveway.
No power is lost to start the process
Even if you somehow power the leaf blower by solar energy the sun will eventually die out ending the power to the blower...not to mention the gas or electricity fall out..
