The Polariton Bose condensate can store energy. How does this condensate do this? The polariton condensate that does this power storage is called a petal condensate.

As power is pumped into the petal condensate the number of petals increases, the frequency of the light that the petals are comprised of increases from red to blue to XUV and then to X-ray. The diameter of the condensate also increases from nano-meters, to millimeters and then to centimeters. At high energy storage levels, the Petal condensate becomes visible to the naked eye. The petal condensate can move around.
The petal condensate is comprised of two counterattacking rings of polaritons. As the energy is pumped into this condensate, the energy is also stored as increasing annular momentum of the rotating rings.
The electric dipole that the petal condensate is entangled with also increases in size.

The diameter of the dipole increases into the millimeters.
The energy storage potential of a petal condensate can get as high as a few GeV.
In the LION reactor meltdown as well as many other LENR experiments, strange radiation is seen. These particle tracks are produced by the energy rich petal condensate as it moves around and absorbs energy using self pumping along it path of travel.
