Here’s another idea – note, too, re how little effort being put into seeing if may be viable, compared to politicians wandering the planet spouting hot air on the issue.
In the worst-case scenario, where global “tipping points” such as the melting of the Arctic ice cap are reached, he claimed launching a fleet of cloud-producing drone ships could save Earth.
Salter, who is famed for inventing the “duck”, a device that generates power by bobbing on waves, said: “We’ve got an explosive with the detonator in it, and when one goes off, it could trigger other explosives. That’s why we need to have a number of solutions. I don’t mean that we should continue burning coal and then just fix the consequences, that would be terrible. Just as a revolver has many bullets, we need several ideas.”
Salter’s idea, which he formed in collaboration with John Latham, of the National Centre for Atmospheric Research in Colorado, is to build boats to sail the ocean and produce a spray of tiny water droplets around which white clouds can form. He suggested that around 400 of these wind-powered boats would be needed, at a cost of £100 million. However, the difficult part would be producing droplets small enough for clouds to form, a technique Salter has yet to master. His struggle has been a lonely one so far, and he holds little faith in government.
Salter said: “In the UK, there is one old aged pensioner, me, and one PhD student in Leeds working on cloud control, and that is it. Then there are politicians travelling the world, holding meetings to say how awful it is and the only outcome is that they organise another meeting to say the same.”
