Michigan researchers have built a prototype of a new auto motor that does away with pistons, crankshafts and valves, replacing the old internal combustion engine with a disc-shaped shock wave generator. It could slash the weight of hybrid cars and reduce auto emissions by 90 percent.
Popular Science took its first extensive look at a gasoline-electric
automobile in 1916.

Hybrid gasoline-electric vehicles began appearing late in the 19th century
from manufacturers such as the Compagnie Parisienne des Voitures Electriques
in France. In this country, an engineer named H. Piper applied for a patent
on a gasoline-electric motor combination on Nov. 23, 1905. By the time Piper
received his patent three years later, however, advances in gasoline engines
had begun to eclipse the performance of his and other hybrids. Among other
