I've also watched the BBC Ancients program. The thing is, that experiment is on a much smaller scale. The mirror is about 10 times bigger than the boat, and I wouldnt think they were able to build such a big mirror. It doesnt have to be alot bigger though, but since the ships IRL will be alot more further away, than in the experiment (where the boat was about an arm's length away from the mirror), it is also alot more difficult to project all the mirrors correctly.
