The system has an axial flux alternator using variable resistance coils which can be individually and selectively turned on or off depending on wind conditions and electrical draw requirements. The coils can also be used to produce mechanical drag on the system as desired to brake the turbine in high wind conditions or for maintenance. The system may be programmed to assess whether electricity generated by the system can be or should be transmitted to a public grid or stored locally on a chargeable battery system.

A center vacuum rotary drill bit including a rotary drill bit body and an insert. The bottom surface of the slot has a projecting key that cooperates with a depression keyway of the insert. Generally vertical sidewall surfaces of a depression keyway and vertical surfaces of a projection key provide mechanical resistance against lateral movement of the cutting insert. This mechanical resistance reduces displacement of the insert with respect to the bit body during brazing and thus a high quality, accurately aligned drill bit assembly is provided by applicants' invention. The depression keyway is designed so as to minimize the effect of the axial load on the insert by avoiding sharp corners which tend to amplify nominal stress and provides an insert of a proper carbide density after pressing. Integral bit body protuberance means adequately separate the insert within the slot and permit braze flow between the insert and slot. The protuberance means enhance braze flow when braze is fed between the insert body and bit body.
