I won't say it can't be done but lifting 100 kg straight up would probably put you into a full scale turbine. Also you would be better with turboprop as your airflow would be spread better and more even. As for fuel load for 90 min. it would be lots. The more power required the more fuel and the model turbines burn about 1/2 lt a min or more.
The only place I know that may be able to give you a bit of info is the GTBA association which is on the web. I would check there.
