In accordance to the laws of thermodynamics, any

efficiency cannot exceed or even reach 100%, but do

not prevent any efficiency from reaching or evenexceeding 90%.

Higher pressures and temperatures (PV=nRT) can allow

greater efficiencies =1-(TC/TH), e.g. TC=300K, TH=3000K,

%=90%.

However, temperatures are limited by ability ofmaterials to withstand high temperature, which is not

the case for magnetic fields (r=mv/qB) that can

withstand very high-temperature ion plasma.

Up to date, all MHD and thermoelectric converters are

still far from reaching 90% efficiency. Most of them

remains below of 30% efficiency.

In space, waste heat cannot be dissipated via

convection and conduction; it can only be dissipatedthrough radiation, which requires heavy radiators with

a large surface area.

A newer and more efficient approach is possible usingphased electromagnetic compression and

electromotive conversion (Electrodynamic Vortices).

It is known that sequential phase variation can producerotating and moving magnetic fields.

Having concentric helix-coils out-of-phase with eachother, forming two contra-aligned arrangementsfor producing opposing helically movingforces resulting in electrodynamic vortices.

Which radially and axially produces twistingelectromagnetic forces, compressing a hot ionized gasF=q(vB), forcing it to expand longitudinally, which

amplifies the alternating EM fields, electrodynamicallyF=i(L B) =(Bv sin) squeezing out its energy to amultiphase electrical system to be effectively harvestedby diode bridge rectifiers (clipping circuit).

Phase rotation keeps plasma centered, preventing very

hot plasma from melting down the coils, opening

possibility of ever higher efficiencies =1-(TC/TH),TC=300K, TH=30000K, %=99%.

Also Multistage Ion Collectors is used for increasing

even more the efficiency, by progressively forcing ions(F=qE) to exchange their kinetic energy into potential

energy (W=qU) slowing/cooling down, and neutralizing

them for collecting their residual energy, which causesan overvoltage on capacitor (E=CV) that is

transferred via three-phase rectifier/inverter to a

battery bank (multidirectional flow of energy).

Contra-aligned (six + six) concentric coils, feed

by six phases p=1 [0 60 120 180 240 300],

for producing opposing twisting electromagneticforces, for axially and radially compressing a hot

ionized gas F=q(v B),

forcing it to expandlongitudinally which boosts

the alternating EM fields

F=i(L B) =(Bv sin)

electricity.

Fusion Energy Source Although energy conversion directly from aneutronic

fusion byproducts can be highly efficient, the wasteheat from electromagnetic losses (bremsstrahlung) inthe reactor's core could make the overall efficiencystay below the breakeven point. However, by turning

the wasted heat efficiently into electricity, the overallefficiency will surely stay well above the breakevenpoint assuring a net gain for the fusion reactor makingit more easily self-sustaining than ever.

Perfect combination, virtually, no thermal andradioactive waste, a dense energy source with anextremely high degree of cleanness and efficiency topower the electrodynamic thrusters.

Fusion fuels: He-3, Li-6/7, deuterium, andB-11; available on moons, planets andasteroids.

Multi-megavolt electrostatic generator (low

charge/mass ratio).Neutralization at outputs (low powerconsumption).

Relativistic Space Drive

Vacuum of space in the universe is filled with

electric/magnetic fields/waves, thus net force is achievable.

Conclusion:

The Multiphase Thermoelectric Convertercan harvestmost of the waste heat from theAneutronic FusionReactorand Electrodynamic Space Thrusters.

By doubling (or even tripling) the overall efficiency ofthermal-to-electric conversion, it can reduce or eveneliminate the need for space heat radiators.

Thus, the spacecraft can take off from an atmospheric

environment just using Phase-shiftPlasma Turbines,and then, in deep space, use Relativistic Space Drive tosurf the spacetime at least at subluminal speeds.
