Method of pre-selecting the life of a nuclear-cored product
A method of pre-selecting the life span of a nuclear-cored product. The method comprises providing a product that uses a nuclear-cored energy source and then determining a pre-selected occurrence. When this pre-selected occurrence happens a timing mechanism in the product will disable the product, thus rendering the product inoperable. Thus a consumer must take the product to a manufacturer to reset the timing mechanism and at this time the product may be updated with new technologies.
1 . A method of pre-selecting a life span of a product comprising steps of:
providing a product having an energy source that uses a nuclear material;
determining a pre-selected occurrence and
providing a timing mechanism associated with the product that disables the product after a pre-selected occurrence.
2 . The method of claim 1 wherein the pre-selected occurrence is a period of time.
3 . The method of claim 1 wherein the pre-selected occurrence is a distance traveled by a vehicle.
4 . The method of claim 1 wherein the timing mechanism is a timing circuit attached to the product.
5 . The method of claim 1 wherein the energy source has a nuclear core that is surrounded by a ceramic phosphor layer, and a photovoltaic layer that surrounds the ceramic phosphor layer.
6 . The method of claim 1 wherein the product is a nuclear-cored battery.
7 . A method of pre-selecting a life span for a nuclear-cored battery comprising steps of:
providing a nuclear-cored battery;
pre-selecting the life span of the nuclear-cored battery; and
programming a timing mechanism to disable the nuclear-cored battery after the pre-selected period of time.
8 . A method of pre-selecting a life span for a nuclear-cored battery comprising steps of:
determining a half life of a material to provide a material having a known half life;
selecting the material having a known half life; and
using the material having a known half life as a nuclear core for a nuclear-cored battery.
