| We are the NEAE-GSI.COM and we have developed and patented the systems listed below. We would be happy to collaborate with your department, even to carry out all the activities in the USA, if you can fully finance the development and production of our disruptive projects.
An Innovative Start UP was born in April 2019 in Caserta, in the south of Italy, able to design, develop and produce one of the largest aeronautical propulsors units powered solely by electricity, capable of delivering all the power necessary to push and fly every size and type of aircraft. We have new ideas, deep technical capacity, enthusiasm and stubbornness, and as the whole world is waiting with strong hope for the use of the only full electric aircraft, so our best business model is the needs and desires of the world population, specially “Fridays for future”. Our Innovative Start Up has the intellectual property of a patent application disclose at Italian Patent Office (UIBM) of the two disruptive items unique in the world up to day: 1) Aeronautical propulsor units powered solely by electricity; 2) Electric only eVTOL shuttle-bus whit 60 sits. The Innovative Start UP was born with the greatest enthusiasm in the development of the new electric technology, but also with the awareness of wanting to give an extra chance to our planet to make the future of our children and grandchildren better, contributing concretely to the decrease in heating of the planet as well as the emission of harmful gases. With our propulsors we want to anticipate the service of solely electric aircraft, since our engine has the size, power and safety of being able to replace existing turbofan engines already operating on all aircrafts in service today recovering all the existing aircraft, in addition to obviously equipping the new aircraft models of the future. |

Aeronomie models the entire aircraft, including the environment, the airframe (6-Degrees-of-Freedom motion and aerodynamics), the power-plant and propulsion systems, and the control and pilot to follow entire missions. Both fixed-wing and multi-rotary designs have been implemented, and an entire mission can be simulated, so that trade-offs between range, payload, energy and performance can be analyzed. Aeronomie comes with a powerful interface to enable efficient large-scale systems simulations.
Within a team for this proposal, we can contribute to the system-level analysis and development: defining component requirements, power-plant systems/propeller design optimization, energy management, power plant control optimization, trajectory optimization for energy-efficiency, etc. We would be able to predict how the motor systems would impact the performance of the aircraft. |

| While going to college i worked via an Electrical Engineer apprenticeship with CONSOL energy. This certified me for working underground and I got my first look at drives and high voltage systems. With my newly found wealth working in the mines, i found the next 4 years in general labor underground in the coal mines. For the last two years of those 4 I was enrolled in a computer tech school completing my degree. I took job placement from there with Adelphia Communications where I got to work at corporate doing technical phone support while watching the broadband base grow from to 50 cities to 50000 cities. I wanted to get back closer to home and bid on a job at a local office where after a couple years Adelphia went bankrupt and i moved into temp work for COVAD communications doing backend phone support for T1 and T3 business lines. From there I took a permanent job working for BEITZEL corporation, a construction company in Garrett County MD. They were at a unique crossroads where mining safety regulation and technology smashed together. Being that I was already a certified miner and had spent the last 4 years in the tech field, I was able to help substantially in the Automation department. After a couple years Beitzel Corp formed Pillar Innovations where i assisted with building the department where i became manager of the automation and atmospheric monitoring product manager. After 9 years i was ask to start an automation department for an electrical contractor startup. Here I was responsible for entire coal preparation plant programming and SCADA systems. This lasted for a year where we started up one entire plant and some train loadouts. After the mining industry started to decline, CLINE Industires was still adding onto their coal plants as planned so all the work was moving to Illinois. At this point I started my business, Xologies Incorporated. Six years in and i can say that finding the right employee is the most difficult part of what a business owner does. Currently we support chemical and control systems using primarily Rockwell Software and Allen Bradley hardware. We also do custom robotics with ARM processors using PYTHON and web interfaces. Best asset is problem solving followed by intercommunication of old and new tech. Process control and control systems in general, just make sense to me. I also coach 2 FIRST robotics tech challenge teams and mentor on other teams. |

Power Generation: Renewable
| Background and interests
Electrical characterizations in nm-resolutions are expected to give critical understanding and guidance for developing novel inexpensive and reliable power electronics. This work proposes unique nm-scale material and device characterizations and failure mechanism analysis of power electronics, by applying and further partially developing a combination of complementary AFM-based nanoelectrical probes including Kelvin probe force microscopy (KPFM), scanning capacitance microscopy (SCM), scanning spreading resistance microscopy (SSRM), and scanning microwave impedance microscopy (SMIM), which operando-image the local electrical potential distribution, carrier concentration, local resistivity or conductivity, and simultaneous local capacitance and conductance, respectively. This set of characterizations will give critical device characteristics including but not limited to junction location, junction uniformity and breakdown, active carrier concentration and uniformity, and local resistivity distribution. The characterizations can be performed with in-situ changes during high voltage, high current, and high temperature stressing, which will give unprecedent understanding about device defects and device failure.
Capability
With more than 20 years of success in scanning probe microscopy (SPM), developed many types of SPM including the world first duel-probe Scanning tunneling microscopy (STM), and applied to a wide range of fundamental materials science and energy science of photovoltaic and energy storage. Published more than 60 first-authored papers and 200 co-authored papers, with most of them being contribution to characterization and mechanism understanding using SPMs. At NREL, we have a set of state-of-the-art AFM-based nanoelectrical probes described above. The home-made KPFM is among the current best voltage resolution of 10 mV. The high voltage mode of KPFM can map high potentials up to 100 V, which is necessary for the power electronics characterizations. Carrier mapping by SMIM can mitigate the requirement of high-quality insulating layer, which is critical for wide bandgap power electronics, but SCM can give higher sensitivity of capacitance signal. We have developed the in-situ high voltage and high temperature stressing for a PV core program, which can be transferred directly to the reliability and failure study for power electronics. Scientifically, I have backgrounds of physics, electrochemistry, and material science. |
