Alternatives to the Internal Combustion Engine (Ayres & McKenna 1972)

Sub titled  "Impacts on Environmental Quality." An American take on the problem from over 40 years ago. 324 pages. Much doubtless out-of-date now in both theory and practice, much still to be researched and developed may be as valid today as was then Perhaps a forgotten idea within these pages holds the answer for you to develop and become a millionaire! Book very good, jacket rather tired looking and worn at the edges
