Yes, it is a good alternative, depending on where it is. Certainly you wouldn't choose to use that if there were a coastal environment or human habitation where the emissions would blow directly onto the community.
But we measured the emissions, and most of the emissions are things like carbon dioxide and water, basically, that go up. There are some aromatic compounds that go up and there's some soot. The levels of those are well within human safety limits half a kilometre or a kilometre downwind.
It will rapidly remove up to 90% of the oil in a short period of time. So, for example, in those Newfoundland offshore burn experiments, there were two major burns where we deployed 50 tonnes of oil—50,000 litres—and over 90% of that oil was removed in just over an hour.
