Us Patent 9,702,573: Nested Heat Transfer System, Sanza Kazadi

Sanza Kazadi

A novel nested heat transfer system comprises a plurality of chained enhanced entrochemical cells with nested structures. Each enhanced entrochemical cell includes a first chamber containing desiccant, or a higher concentration solution, and a second chamber containing refrigerant,   or   a   lower   concentration   solution.   Preferably,   the   first   chamber   and   the   second   chamber   are   connected   by   a   conduit.  Furthermore,   a   smaller   chamber   in   an   enhanced   entrochemical   cell   is   encapsulated   by   a   larger   chamber   in   an   adjacent   enhanced entrochemical cell, thus forming a nested structure between the two enhanced entrochemical cells. A chain of enhanced entrochemical cells with a plurality of such nested …

An entrochemical energy transfer system and a related process for obtaining work from environmental thermal energy are disclosed. In one   example,   a   plurality   of   linked   entrochemical   cells   with   nested   chambers   provides   an   aggregate   thermal   gradient   of   each entrochemical   cell   by   transferring   environmental   thermal   energy   in   and/or   out   of   the   plurality   of   linked   entrochemical   cells.   The aggregate thermal gradient generated from the plurality of linked entrochemical cells can be utilized as an environmentally­ friendly energy source for human needs. The entrochemical energy transfer system and the related process for obtaining work from environmental thermal energy utilize a set of entropy transfers …


An Entrochemical Water Heater, Sanza Kazadi, Sabrina Lin, Kelvin Ye May 2016

An Entrochemical Water Heater, Sanza Kazadi, Sabrina Lin, Kelvin Ye

Sanza Kazadi

Entrochemical systems are systems capable of generating internal thermal gradients through internal
water movements which simultaneously transfer get of vaporization between internal water reservoirs. These systems move to a chemical equilibrium state that generates and maintains a thermal gradient. Entrochemical thermal batteries (ETB) can be constructed which extend the thermal gradient of a single cell through an additive process. Such systems can deliver useful work. Additionally solutions used therein may be recharged passively using environmental heat.

We describe the design and function of a bench-scale water heater capable of heating a small water
reservoir. The system is powered by an …


Compact Single Multistage Distillation, Sanza Kazadi, Brent Usui, Ashley An, Robin B. Zhao May 2016

Compact Single Multistage Distillation, Sanza Kazadi, Brent Usui, Ashley An, Robin B. Zhao

Sanza Kazadi

We report the design and function of a distillation apparatus which uses salt concentration gradients to
drive distillation and desalination of simulated sea water. Utilizing the entrochemical effect, the system
generates an internal thermal gradient. An internal distiller is arranged with the condenser in the cold end of the
entrochemical system and a seawater reservoir in the warm end of the entrochemical system. The heat of
vaporization is recaptured in the cold side of the entrochemical system and re-used. The spent solution in the
entrochemical system can be recharged using evaporation, making the surrounding thermal energy the source
of energy …


Entrochemical Thermal Battery Design For Atmospheric Heat Collectors Sep 2015

Entrochemical Thermal Battery Design For Atmospheric Heat Collectors

Sanza Kazadi

We present two novel design modifications to the basic entrochemical system which enable the generation of an entrochemical thermal battery. The inclusion of a passive mixing mechanism enables the continual disruption of the water layer that forms at the top of the saline solutions, enhancing the overall thermal gradient. Embedding of one cell’s cool side in the previous cell’s warm side allows efficient conduction of thermal energy between the two, effectively driving the additive property of the overall thermal gradient, the battery effect. We demonstrate that the passive mixing mechanism enhances performance, generating a one-cell gradient of 18.3 ± 0.3◦C …


Low Cost Solar Chimney Performance-Improving Enhancement, Sanza Kazadi, Meishan Liang, Aaron Togelang, Daniel Chan Sep 2015

Low Cost Solar Chimney Performance-Improving Enhancement, Sanza Kazadi, Meishan Liang, Aaron Togelang, Daniel Chan

Sanza Kazadi

Solar chimneys are potentially important components in energy-providing systems. These are
passive solar systems which transduce solar irradiance to airflow. The airflow, in turn, can be transformed
into electricity. While the ability of the solar chimney to create airflow has been examined in a number of
different studies, little attention has been focused on improving the performance of the solar collector. In
principle, increasing the thermal lift of the chimney would improve the chimney's overall airflow
production and extend the upper limit of energy production.
We examine an improvement to the solar collector design for the simple solar chimney capable …


Us Patent 8,338,976: Magnetically­-Levitated Wind Turbine, Sanza Kazadi Dec 2012

Us Patent 8,338,976: Magnetically­-Levitated Wind Turbine, Sanza Kazadi

Sanza Kazadi

A novel wind turbine configuration utilizes a permanent magnetic male and female levitation support for magnetic levitation. The novel wind turbine has a female part attached to a payload which is magnetically levitated above a male part of the levitation support. The female part and the payload are further operatively attached to a vertical axle structure which is held stationary by a point of contact. The point of contact and the vertical axle structure provide a stable axis of rotation for the payload and the female part, which can be rotated with near ­zero friction due to the magnetic repulsion …

Sanza Kazadi

A levitating mount apparatus is provided which utilizes a permanent magnetic male and female levitation support as described in U.S. Pat. No. 7,501,922. The mount has two general forms. In one general class, the mount is attached to an axle aligned with the axis of symmetry of the female part of the permanent magnetic male and female levitation support. In the second class, the female part of the permanent magnetic male and female levitations support is attached to the bottom of the mount, and no axle is utilized. The mount is stabilized using a stationary support structure which has limited …

We describe in this paper a novel water distiller. The water distiller utilizes a thermal gradient device which spontaneously generates and maintains a thermal gradient through a process similar to osmosis. A theoretical derivation of the process which we call an entrochemical process is presented. The device utilizes the thermal
gradient to induce a flow of energy through the system. This flow of energy is used to induce the distillation of water. The device may be recharged using a low-temperature evaporation process. We describe the
design of the device, which has a distillation process that has an efficiency of 12.6 …
