MORE EFFICIENCY IN FUELS SOUGHT New Types of Gas Motors Vital, Says Re- search Expert. or Sither the building of more efficient motors or the obtaining of more power from the fuel used will be forced by the enormous increase of automobiles in the United States, in the opinion of C. F. Kettering, sident of the Gen eral Motors Research Corporation About 5 per cent of the possible en- ergv in gasoline is being obtained to day. while 95 per cent of it is thrown away, declares Mr. Kettering, who is former president of the Society of Au- tomotive neers.
