In addition to high efficiency, Cool Chips™ are expected to be very inexpensive to make.

A number of factors come into play when estimating the cost of a product like a turbine or a compressor. The marginal costs (the cost of making one more unit on an already-present assembly line), are heavily dependent on the following factors:

1: Materials quantity. No device can cost less than its parts. And big, heavy machines like turbines and compressors have a lot of steel, copper and iron in them. This is an unavoidable cost. Cool Chips use very little in the way of raw materials -- at least an order of magnitude less than the competition. A single chip, capable of 100 watts of cooling, will measure less than 1 cm on a side, and be only a few millimeters thick.

2: Material quality. As machines improve, the specifications for their components become ever-more demanding. If the components must be of very high materials purity, a significant cost is added. This cost, unlike, say economies of scale, is not reduced easily. The price of 99% pure iron is far less than 99.9999% pure iron. Cool Chips can use relatively impure materials.

3: Machining/assembly costs. The more welding, bonding, sealing, etc. which is required, the higher the costs as well. Cool Chips are extremely simple to manufacture -- much less complicated than an Intel 386 processor, for example.

4: Component costs. The more piece have to be put together, the more it will cost. Cool Chips have a very small component count, much less than competing technologies.
