Microvision's current pico projection engine uses red and blue laser diodes and a frequency-doubled "synthetic" green laser to create a full color image.
You can count up 5.8 million BTUs (that's how many BTUs a barrel of oil yields) from a wood stove, or a diesel engine, or a microprocessor, or a laser.
Thus, Canon's core engine technologies still hold nearly 60% of the laser-printer market, including machines sold through an alliance with Hewlett-Packard.
The fast-ignition technique is more like a petrol engine: first the fuel is compressed and only then is it ignited by a second laser pulse acting as a spark plug that is fired through a hole in the pellet.
