Internal Design Work

As part of the SES mission, ongoing internal design work is performed on topics of interest. The design studies, white papers, and patents provided below summarize some of that work and are provided as insight into areas of interest. This page is regularly updated as new design work is completed, so stay tuned for new developments!

Design Studies

Design studies are short summaries of design concepts. Their purpose is to explore feasibility and make a determination on the value of further evaluation. This may include physical designs, concepts of analysis, or any other discussion on potential solutions in a summarized basis.


Moving Walkway for Mass Transit

A mass transit system based on small diameter tunnels and a new concept in high-speed moving walkways.


Skid-based Automated Flash Evaporator System (SAFES)

The landing page for entry into the Innovation Phase of the DOE Solar Desalination Prize.


Armadillo Demonstration Platform

A brief look at a proposed platform for showcasing future sustainable living technologies. The platform consists of a Recreational Vehicle styled to match the upcoming Tesla Cybertruck.


Portable Coffee Maker

A design study for a novel approach to making coffee. The described concept is a portable coffee maker with complete control over the brewing process.

Point Conditioning System

A concept for distributed air conditioning is explored. It is part of a sustainable and energy efficient residence concept that has an integrated central chill water system.

Portable Research Wind Tunnel

Initial conceptual design of a portable wind tunnel. Transport is possible with standard vans and man-carry of components.

White Papers

White papers are analyses of proposed designs. Often they are an extension of design summaries where additional analysis is performed to further increase confidence on design feasibility.

Simulation of a Miniaturized Flash Evaporator System

Documentation of a simulation used to validate feasibility of a miniature flash evaporator to provide solar water desalination.

Residential Hot Water System

The feasibility and potential for a central hot water loop to be integrated with a single family residence is analyzed.

Portable Wind Tunnel

The power requirements, weights, design, and airflow characteristics of the portable wind tunnel conceived during a design study are determined based on analysis.

Program Planning Analysis

A description of a developed Monte Carlo analysis program is provided that shows the capability of the tool to determine the impact of risk and uncertainty on project metrics.


Inventions are design items that are being considered for “reality”. This can come in the form of existing products, ongoing prototyping, or patents.

PATENT APPLICATION - End Effector Coupler for Surgical Arm

Demetrius Siachames was named as co-inventor on two patents for a novel coupling system on a surgical assistant arm. Demetrius’ contribution was to develop a design that allows for one handed operation for a stable connection. The major challenge was developing an interface between the instrument and surgical arm that was stable when considering the wide manufacturing variability anticipated for different instruments.

The two patents are linked below:

PROVISIONAL PATENT - Moving Walkway for Urban Public Transit

Provisional Patent Application 63077187 was filed by Demetrius Siachames as a next step in finding ways to commercialize the approach. SES looks forward to working with transit companies, city planners, and other visionaries in revolutionizing how people commute in urban centers.

PERCUSSION EQUIPMENT - Mechanical Designs for KLS Percussion

SES in collaboration with KLS Percussion has designed and manufactured percussion equipment and new parts that enhance the operation of existing equipment. Designs include chime mallets, foot operated cymbal damping machines, castanet machines, snare spreaders, and practice pads. For more information and details contact KLS Percussion.

Explanation of Fields in the SMARRT form submission

Reference Scenario Inputs:

Number of People Infected – How many potential members of the gathering are infectious. The simulation starts when they enter (time=0).

Type of Activity – Impacts the number of particles spread as aerosols per respiration. More strenuous activities result in more viroid particles being released.

Air Changes per Hour – This is the air exchange rate with fresh air for the volume of air being breathed by the gathering. If you use forced air exchange, you can calculate the number of air changes per hour for your specific situation.

Space Floor Area and Ceiling Height – These are used to calculate the total space volume.

Duration Infectious Person is Present – This is how long the infectious person stays in the space after their initial entry. For the reference scenario, this defines the end of the simulation.

Gathering Scenario Inputs:

See the reference scenario for all inputs up to Time of space entry.

Time of space entry and exit – These values represent when you enter and leave the space referenced to the infectious person. For example, if you show up fifteen minutes late, but stay an hour after the end of a one hour party, the Duration Infectious Person is Present is 60 minutes, the Time of Space Entry 15 minutes, and the Time of Space Exit 120 minutes
