turbine in microturbine generator for aircraft?

I googled, but there's not much infor. about converting the turbine in
the microturbine generator for aircraft use. So I am tossing my idea
here. The Capstone's microturbine generator looks very neat. The
generator has 60kw output, and the turbine itself should have higher
output, enough for a two-seater and it's light,very light.

So how do you think about the idea?

Thank you.
