In principle it is a nice idea to convert directly to heat. However, it is unlikely to be as efficient because:
1 conversion to electricity should be 70-80% efficient. And controls can be simple since frequency is not very important and voltage can also vary. 2 conversion to heat is 100% efficient (simply I*I*R) 3 heat can be easily prioritized using thermostats. 4 transport of electricity is likely to be much cheaper, more efficient and more reliable.

Good Idea BUT there are too many "constrictions". Mill Location Heat transmission distance Equipment to implement Heat "PUMP" Cost of overall Wind Mill Heat Pump And some other "requirements" THEN you may discover that producing electricity, the cost will be lower even if the distance mill-to-heated place is close. It may be that you WILL BE DARNED after all.
