Thermal Heterodyne, background and equipment Author: David Judbarovski, systems engineering, principle invetor judbarovski@gmail.com Background Thermal EM waves mixed and further filtered, it transforms high frequency band in much lower frequencies, allows to produce electric power by antenna with rectifiers named rectenna, can serve as a generator of heat-into-electricity with energy efficiency can reach near 100% Equipment for it comprise pairs of radiators in a form of angle being heated with small temperature differential T1 – T2, while open side of the angle emits heat EM waves on rectenna. Ideally, such kind of generator’s energy efficiency is n = (T2 /T1) ^ 4, while frequency band of rectenna is as small as (T1 – T2)/ 20 (THz), so total energy losses is small too. Really, if T1 = I200 K, and T2 = 1150 K, n ~= 85 %, at rectenna’s band being 2.5 THz being now quite feasible possibility. The said radiator can be heated by any heat source, as fuels as waste heat etc...

Breakthrough novelty for sea vessels - Upgraded Author: David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Being elevated by two or more jets, comprise pumps with inlet being underwater, and with high velocity down outlet, sea vessels can transport heavier weight at lower displacement with less drag force and/or bigger travel velocity. It can sufficiently cheapen the cost and/or time for transportation. A counter flow can be used as additional pump (jet) up to solely for such elevation of the sea vessel during route. All those can improve possibilities for now operated sea vessels as big ones as small ones, as civil ones as military ones, or used for new generation of sea vessels of more suitable design for such improvement.

Two types of novelties for sea vessels, are breakthrough ones Author: David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Abstract Being elevated either by counter flow through tubes with vertical output being attached to the bottom, or by water jets consuming underwater, or by the both ones, it allows, to transport a more heavy weight at lower displacement with less drag force and/or bigger travel velocity. All those and each of them separately can sufficiently cheapen the cost and/or time needs for transportation. It can improve possibilities for now operated sea vessels as big ones as small ones, as civil ones as military ones, or used for new generation of sea vessels of more suitable design for such improvement.
