I would think this would require a rather high powered laser, the kind that'll blind a person. I'm not sure I'd be comfortable working around something like that.
The cost will also be rather high, but if they plan on using it in high end vehicles the extra couple thousand dollars won't be that big of a deal.
Also, I wonder how they plan on keeping the lense in the cyclinders clean? I would think carbon would coat it almost immediately, leaving it useless. Carbon ignites at nearly 1300F while gasoline ignotes at 536F, and probably lower when compressed in a cylinder. That means the carbon won't burn off and the lense will be fouled. It should also be pointed out that carbon burns around the same temp that steel melts.
Should be interesting to see how they pull this off. If they can, it'll be an incredible ignition system.
