Has anyone tried silicon spray on a table saw blade, to reduce power

Silicone and woodworking do not mix. Don't get silicone anywhere near
anything used to work with wood. Plays Hell with both finishing and
adhesive bonding, and the stuff is almost impossible to remove once
applied.

I've had good results from sawing through a piece of UHMW polyethylene
(wasn't looking for improved cutting, my objective was to cut the
polyethylene).

There are purpose-made lubricants.

is another.
