A micro-electro-mechanical generator has a housing, a heater, a cooler, a heat transfer member, a supporting member, and fluid. The fitting is specifically suited to interconnect vertical electrical conduit runs and horizontal electrical conduit runs in commercial construction environments. A second current source selectively supplies a second current to the summation circuit. The wheel is attached to one of the sides near the ladder base and is adapted to rollably support the ladder base when the ladder is moved. Coatings which are produced utilizing the present invention have high gloss values heretofore unobtainable using aqueous coating compositions.
