Ben Franklin’s Laser

by Doug Beason

It appears that the sun will go nova in 75 hours, which leaves Grayson to go back in time to give a boost to science in Ben Franklin’s time.
It sounded nice and simple: allow Ben Franklin to invent the laser and let the technology casade. Grow enough so that in five hundred years we’d have something to get us out of this mess.
