Eric, Axil, Jones,

I just want to make a couple of brief remarks.

First, there appear to be ways to greatly concentrate energy in "cold"
environments, e.g., superfocusing of e-m waves by plasmons in nano-
structures, various focusing phenomena, superoscillations, ...

On the "hot" vs. "cold" distinction -
I believe this is partly hard to define since "kinetic energy" is
itself ambiguous.  For example, read -
"How Much of Magnetic Energy Is Kinetic Energy?"
http://puhep1.princeton.edu/~mcdonald/examples/kinetic.pdf
Let's not forget, too, that a slow compressed quantum wave function
can possess more K.E. than a fast moving wide, smoothly varying one.

On whether "heavy electrons" can split gammas -
If I understand correctly, an electron becomes "heavy" in strong fields
when it accrues a entourage (or "dressing") of a "swarm" of photons
of field energy/momentum.  It's a really difficult QED problem to
determine cross-sections and scattering probabilities.
Try googling "semi-bare electrons" or "two photon bremsstrahlung" or
"multi-photon bremsstrahlung" - electrons are not femto-billiards.
