Description

1931 edition. Discusses how scientific research focused on developing high-speed engines during World War I, leading to dramatic improvements in power and efficiency. Now, light, high-speed engines dominate applications like transportation where their advantages of weight and fuel efficiency are most important.

Volatile liquid fuels like petrol and benzene are critical but limited resources, so alternative sustainable fuels like alcohol must be developed to ensure future fuel supply for internal combustion engines.

Hardback in good condition for age, blue boards in very good condition and inside clean, bright and well bound.

Nice example of a scarce early edition.
