Absolutely. Dougmc has given you the correct answer in every respect. This is basic. You can't get any benefit from adding a lossy regeneration system. The losses you add are ALWAYS, ALWAYS, ALWAYS greater than the gains. Let's say you generate 10W with your turbine. You will require 10W divided by the efficiency of the turbine to obtain that power. Let's say the efficiency overall of your turbine (air screw + generator) is 50% (probably very optimistic). You will then require 10/.5=20W MORE power from your electric drive to overcome the additional drag for a net waste (loss) of 10W.
