I claim...

[Mike Deeth]

I claim:

1. A device for generating fusion energy comprising:
a.) spherical inner chamber
I. with a reflective interior surface,
for the purpose of preventing heat
loss and lowering the temperature in
which ignition occurs
II. with provisions for pumping
electromagnetic radiation inside the
chamber, so that the fluid inside can
be used as a laser gain medium and
also for the purpose of optically
tracking the fuel
b.) spherical outer chamber
I. surrounding the inner chamber
II. with provisions for acoustic &
electric transduction, enabling
pre-ignition movement and compression
of the fuel and also enabling
post-ignition harvesting of the
blast’s kinetic energy
c.) space between the two chambers
I. filled with a fluid
i. that is an acoustical medium
ii. that cools the inner chamber
d.) space inside the inner chamber
I. filled with a fluid that
i. circulates as an efficient
high-temperature coolant
ii. encapsulates gaseous fusible fuel
inside of a bubble
iii. is transparent to selected
electromagnetic frequencies
iv. is a laser gain medium that can
amplify selected frequencies,
so that the inner chamber can
function as a spherical laser
cavity
v. is an acoustical medium, enabling
fuel transport and compression
vi. blocks x-rays, preventing damage
to the chamber walls
vii. absorbs neutrons, preventing the
escape of hazardous radiation
viii. breeds tritium, replenishing the
supply of easily ignitable fuel
ix. slows fuel dispersion during
combustion, increasing burn-up
fraction
2. A method applying to the device according to
claim 1 where said method accurately determines
the location of a bubble using the technique of
multi-occultation triangulation.
3. A method applying to the device according to
claim 1 where said method is used to move a bubble
by manipulating the pressure in its local
environment, based on the ideas that
a.) a bubble’s size is determined by the
background pressure
b.) a bubble’s direction of motion coincides
with the buoyant force and is determined
by the pressure gradient
c.) the interplay between the buoyancy force
and drag force causes large bubbles to move
faster than small bubbles when subjected to
the same pressure gradient
d.) fluctuations in the background pressure can
be synchronized with fluctuations in the
pressure gradient, so that, even though the
bubble is pulsating backwards and forwards
in tiny steps, large overall displacements
can be accumulated.
4. A method applying to the device according to
claim 1 where said method causes thermonuclear
ignition in a bubble of fuel, comprising
a.) positioning the fuel at the focus of a
spherical laser cavity so that
i.) the fuel will not be able to
effectively cool by radiating away
light
ii.) the reactors structural components
are well shielded from the
explosion, making larger yields and
higher gains possible
b.) making the cavity laser-active, by pumping
it with enough light to cause an upper-state
population inversion
c.) squeezing the fuel, so that
i.) the fuel becomes hot and radiates
brightly (sonoluminescence)
ii.) the fuel’s radiation creates an
outgoing laser cascade
iii.) the fuel is in a state of
pre-compression when the cascade
returns
iv.) the fuel is further heated and
compressed by the powerful laser
effect
d.) containing (preventing dispersion of) the
fuel, so that
i.) the fuel can self-heat, lowering
the energy required for drivers
ii.) a greater fraction ofthe fuel gets
burnt, increasing the gain
iii.) low-temperature volume ignition is
possible
