[Rockhounds] OT: Death Rays and melting stones

[Kreigh Tomaszewski]

A:

	Dig a pit for the dish (to eliminate the 1.5 meter distance up) next 
	to a circular ramp/platform to hold the block of stone. FP 
	determines the radius of the pit.

	Mount the dish on a cart constrained by rails at the sides of the 
	wheels to get horizontal movement of the FP. Tip the top of the dish 
	forward/backward to get vertical movement of the FP.

	Put the rails and cart on a second cart constrained to move at right 
	angles to the first cart.

	Put the bottom cart on a platform that can be rotated to follow the 
	sun.

	Now you have X-Y-Z control of the FP and can work a stone block as 
	the sun moves. You may need to move/rotate the stone block from time 
	to time.

B:

	Hang the dish from a beam between two poles (roughly) oriented at 
	sunrise and sunset. Connect two more ropes to the dish edge 120 
	degrees from the suspending rope. Now you have X-Y-Z control of the 
	FP. Put it in a pit if necessary to eliminate the 1.5 meter distance 
	up.

I wonder if any (unexplained) circular (or semi-circular) pits have been
found in the Inca ruins?
