Red Sea Dam
The so-called Red Sea dam is a speculative macro-engineering proposal put forward in 2007 by a group of scientists and engineers[1]. The proposal has attracted both criticism and ridicule[2] although the authors' intention seems to have been to explore "the ethical and environmental dilemmas and some of the political implications of macro-engineering".
Proposal
The idea is to dam the Red Sea at its southern end where the Bab-al-Mandab Strait is only 18 miles wide. Natural evaporation would rapidly lower the level of the enclosed Red Sea. Water allowed back into the sea would drive turbines to generate electricity. It is claimed that up to 50 gigawatts would be generated, dwarfing all other power schemes. However, this level of output might not be achieved for up to three centuries when the Red Sea had shrunk to a fraction of its current size and the sea level had dropped by hundreds of metres.
Implications
The proposal's authors point out that "Macro-engineering projects of this size cause a massive destruction of existing ecologies", a point emphasized by critics[3] who can point to the damage caused by current, far smaller schemes.
The authors claim "Green" credentials for the idea: "On the positive side of the environmental scale, however, are the big reductions of greenhouse gas emissions, and the reduced pace of fossil hydrocarbon resource exhaustion".
Influential scientists such as Peter Bosshard[4], policy director of the International Rivers Network, have condemned the scheme as ludicrous.
What some influential scientists have overlooked, however, is the same authors earlier macro-project proposal for a Hormuz Strait Dam mentioned in the text and cited fully. [5]
