Greens Embrace Military Technology?

Technology that has previously been used to mark out minefields may have found a new use in life – keeping (some) sea life out of fishing nets. The BBC article describes how the animals that use sonar for navigation could be helped by making it obvious that the net involved some physical barrier; currently the nets do not bounce enough sonar back to the animal, and so can entangle, and slowly kill dolphins, porpoises, smaller whales etc.

Previously, battery powered devices were used to mark out mine fields, however these have obvious drawbacks when the battery runs out and needs replacing.
