Malcolm Slesser (30 October 1926 – 26 June 2007) was a Scottish energy analyst, scientist and mountaineer.
[2] The author of more than 100 published technical papers, Slesser's books ranged from energy systems and the environment to exploration and sustainable development.
[3] Slesser pioneered the study of the potential for economic growth that led to methods for estimating the economic carrying capacity through the ECCO (Evaluation of Capital Creation Options also referred to as the Enhancement of Carrying Capacity or Economic Coordination Options) model of an economy uses the stocks-and-flows paradigm (aka system dynamics) to track energy and other natural capital flows through the economy.
Then John Hunt (of the Alpine Club) and Slesser (of the SMC) received telegrams from the Soviets granting permission for a party of 12 British climbers to mount an expedition to the Pamirs, provided the two joined forces.
Slesser said of this: "It was a bit like proposing that North and South Korea should co-operate on making a nuclear bomb."
