Query: Laser induced nuclear waste transmutation   When producing electricity that collects the mass energy that is available at
the time of the induced disintegration of radioactive elements, other unstable
elements are produced with half-life span durations ranging from less than one
second to hundreds of thousands of years and which are considered as waste.
Managing nuclear waste with a half-life of less than 30 years is an easy task,
as our societies clearly know how to keep buildings safe for more than a
century, the time it takes for the activity to be divided by a factor of 8.
High-activity, long-lasting waste that can last for thousands of years or even
longer, up to geological time laps, cannot be taken care of for such long
durations. Therefore, these types of waste are socially unacceptable; nobody
wants to leave a polluted planet to descendants.
