The one on battery-powered delivery truck* appeared in a recent issue of "Food Processing" with a circulation of 40,000 who are potential customers for this type of truck. The other appeared in "Progressive Architecture" with a circulation of over 41,000 In the architectural profession. Vith regard to the electric trucks, we hope soon to have additional co3t data which will enable us to publish a more detailed brochure uu i~- r-vJct. The article 00 sound barriers is, of course, the result of our own brochure which contained the report of Bolt Beranek and Bevman. Additional copies of each are available In quantities up to 25 free of charge. Larger quantities of the electric truck reprint can be supplied at our cost of seven cent* per copy, and of the sound barrier article at five cent* per copy. Very truly your*.

Electric trucks take over A SILENT REVOLUTION may be In the making on the streets of America's cities and towns, and on the highways immediately surrounding Cm larger population centers. Reason is re-introduction of the once fanuiee*. ve hicle, but in an entirely new ' --n -- as a short-haul pick up and delivery vehicle. Several national dairy or ganizations are making home deliveries in electrics which cost about one-third to one- half as much to operate as conventional gas-powered trucks, nod whose noisiest activity on milk mutes Is the clink of bottles which the driver collects. The truck itself makes hard ly any noise la operation, and, of course, never sits Idling at the curb -- ordinarily a source of fumes, noise and high truck- operating costs. (As example of the econom ic impact of "idling," tests on the rcute show* that a home- dehvery-route truck spends 70-75 per cent of its time idling, and averages only four to five miles per gaL Idling aUo is one of the causes of high engine maintenance costs.) la one test, an Atlantic City dairy compared 3000-lb-capec* ity chx-t.se trucks and 2500-lb* capacity gas trucks. In a 17-day trial last April over seven routes on Atlantic City's Absccon Island, the electric "fuel" (recharging) cost of about two cents per mile compared with an av erage gasoline cost of 3.66 cents per mile for standard four-cylinder trucks. .V*v"uh electric "fuel* costs depend a gousi on load carried, holiness of tei- rain. number of stop* made and kilowatt-hr cost, a typical test run of 23 miles required 42 kw hours, or 2375 cents per mile. Still another test, by a dairy in Warren, Ohio, over routes ranging from 12 to 20 miles, showed an average per-mile cost of 13 cents for recharging. This compared with gas-and-^i oil costs of 123 cents per mil<^ on the same routes. Tn the latter test, electric power was puAch?<*d during an off-peak (batteries were re charged at night) for 0.8 cents CJ trft4t k** vfcf aUctrls H $*i*i*f c**t d> r*At*f* tvff Hi* t**+r+*l tMwhwti** Tfowfk * tk-- * tk*ri, (til *4 im tW u* p*ft*4 k*l *h*w* 20 a*r * . i*W *4 *b**4 M p** t*4 in til* fn<* *1 nwfiMH Imi d*cr***d W u* s--4+g 7MW^ I mm PRO( l SMM, ****njm?i w ffw.i -gw  JJ11 I'll il)BI IIJJIIII LIA2A538 per kw hr.
