An investigation of the possible extent of the re-spending rebound effect in the sphere of consumer products [PDF]

open access: yes, 2002
A key method used to reduce the environmental impact of a product is to make it more energy efficient. Previous studies have found that the potential benefits from improved efficiency are often at least partially negated by increased use of the product.

Rockwell Numbers and Rebounding Numbers of Steel Balls

open access: yesThe Journal of the Japan Institute of Metals, 1942
It has been a general practice that the C scale of Rockwell hardness tester was widely used to measure the hardness of steel balls. But, to acquire the true hardness number of steel balls, the relation between the hardness munber measured on the spherical surface and that on the plane surface should be considered.

Energy efficiency and the rebound effect [PDF]

open access: yes, 2009
In recent years the argument that rebound effects, triggered by economy-wide price and income effects, may partially or wholly offset reductions in energy consumption expected from energy efficiency improvements has gained a great deal of attention in ...
