Princeton Optronics' Laser Ignition Could Boost ICE's Efficiency by 27%

A team at Princeton Optronics working on replacing conventional spark plugs with laser igniters has produced a running engine and they claim that replacing spark ignition with lasers could improve the efficiency of gasoline powered engines by 27%. Considering that the basic design of the spark plug hasn’t really changed in over a century, this would be a revolutionary step, frickin’ lasers or not.

Tassos Isn't this just a Golf Wagon with better styling and interior?I still cannot get used to the fact how worthless the $ has become compared to even 8 years ago, when I was able to buy far superior and more powerful cars than this little POS for.... 1/3rd less, both from a dealer, as good as new, and with free warranties. Oh, and they were not 15 year olds like this geezer, but 8 and 9 year olds instead.
ToolGuy Will it work in a Tesla?
ToolGuy No hybrid? No EV? What year is this? lolI kid -- of course there is an electric version.
Tassos No, this is for sure NOT my favorite Caddy. Very few Caddys with big fins work out as designs.FOr interiors, I much prefer the Caddys and other US luxury cars from the 30s, Packards etc. After the war, they ditched the generous wood veneer (without which no proper luxury car) for either nothing or the worse than nothing fake wood.For exterior, I like many Caddys from the 60s and early 70s, when the fins slowly diminished and finally disappearedEven the current " Art and Science" angular styling is quite good and has lasted a quarter century (from the first CTS). They even look better than most Bangled BMWs and even some Mercs.- from outside only.
ToolGuy Good for them.
