Tænk hvis du aldrig skulle tænke på at genoplade batterierne i din mobil eller bærbare pc ... men ville det kræve blyforklæde?

Researchers have demonstrated a penny-sized "nuclear battery" that produces energy from the decay of radioisotopes.
As radioactive substances decay, they release charged particles that when properly harvested can create an electrical current.
Nuclear batteries have been in use for military and aerospace applications, but are typically far larger.
The University of Missouri team says that the batteries hold a million times as much charge as standard batteries.
They have developed it in an attempt to scale down power sources for the tiny devices that fall under the category of micro- and nano-electromechanical systems (Mems and Nems).
The means to power such devices has been a subject of study as vigorous as the development of the devices themselves. [...]

I think this will be an amazing advancement for mobile electronics in the near future. As long as they are proven to be completely safe, we should have no reason to deny there public use. I believe we are far passed the problem of nuclear spills through public use, and since cellphones and laptops are already not very good for us, this should get people to either stop using them all together, or just not be worried. I am sure that if we are allowed the use of these batteries then we will definitely save a lot of money on replacements and extras. Of all industries that needs this development it is the laptop industry. They are the worst running batteries made.
