Circular Economy: Theoretical Benchmark or Perpetual Motion Machine?

Is whole-culture synchronization biology's 'perpetual-motion machine'?

Whole-culture or batch synchronization cannot, in theory, produce a synchronized culture because it violates a fundamental law that proposes that no batch treatment can alter the cell-age order of a culture. In analogy with the history of perpetual-motion machines, it is suggested that the study of these whole-culture 'synchronization' methods might lead to an understanding of general biologica...

Waste and circular economy

A Neo-Classical Benchmark Economy

In these notes, we discuss a dynamic stochastic general equilibrium (DSGE) economy with complete markets. This model serves as a useful benchmark and point of departure for many questions in macroeconomics. It also serves as a simple first pass at a positive model of business cycles or asset pricing in closedand open-economy contexts. You should familiarize yourself with all the salient feature...

Damage-induced aging and perpetual motion

Correspondence to: Mikhail V Blagosklonny; Email: [email protected] Submitted: 06/20/13; Accepted: 07/01/13 http://dx.doi.org/10.4161/cc.26015 The United States Patent Office has made an official policy of refusing to grant patents for perpetual motion machines (perpetuum mobile) without a working model. Should we adopt a similar policy for manuscripts claiming that aging is caused by...

Landfills And The Circular Economy

Promotion of resource efficiency and development towards a circular economy is widely supported. Many products and materials that are brought into the economy contain hazardous substances. These substances may be acceptable during the consumption stage, but due to accumulation in the environment may also cause impact to human health and the environment after consumption. The primary goal of was...
