| BACKGROUND
Quantum Designed Materials (QDM) is an Israeli-US company founded in 2014 that develops superconductors, materials that carry electric current with no resistance. Our initial products still require liquid-nitrogen cooling, while we are on the roadmap to develop the world's first room temperature superconductors (RTS).
INTERESTS
The commercial applications for superconductive materials are widespread:
• Light-weight wires and cables for onboard power distribution, per the FOA in FRI-0000050: CONNECTING AVIATION BY LIGHTER ELECTRIC SYSTEMS (CABLES).
The first objective of this FOA is to "Identify appropriate wiring materials (i.e., conducting or superconducting) with optimum gravimetric power densities and minimum electrical losses". Our novel materials answer this quest in full.
We are interested in teaming up with wiring and cable makers, to integrate our superconductors as the core conductor in their wire.
• Quantum computing: the technology enabling superconducting qubits, equivalent in output to transistors, will be generated by QDM. We will enable the development of Rapid Single Flux Quantum (RSFQ) technology, where transistor gates are replaced by Superconducting Quantum Interference Devices (SQUIDs) - operating 10 times faster and with ~100,000 times lower power consumption compared to CMOS circuits.
• HTS (High Temperature Superconducting) cables for electric grids, first as an upgrade of the current 2nd generation HTS cables ("2G") – these are QDM's "3G THS Cables", then followed by room temperature high intensity cables.
• Motors and generators: research concludes that large HTS motors will have approximately half the losses of conventional induction motors in such applications.
• Fusion Reactors: current fusion reactors use high field magnets built from 2G HTS wires. Our 3rd generation tape would fit into the same installation, but with increased operating current, enabling to reduce the cooling costs dramatically. These are key for the commercial realization of fusion reactors.
CAPABILITIES
Based on demonstrated POC capabilities achieved already, we expect to soon show an order of magnitude magnitude higher critical current density at 77K than existing 2nd generation materials. We have also measured results of critical temperatures significantly higher (150K) than the Tc of cables currently used today (77K), for production cables targeted at as low as $20/kAm. |

Other Energy Technologies
| Capacitech Energy, Inc. is a funded, high-tech startup that is commercializing its proprietary, flexible, and wire-shaped supercapacitor called the Cable-Based Capacitor (CBC). Its unique feature is that it can go where supercapacitors are needed, but have never gone before, inside a product or system's wiring infrastructure.
Batteries are designed to deliver energy over long periods of time, but struggle to deliver it quickly and can be damaged or aged by attempting to do so. Supercapacitors are designed to deliver energy very quickly (providing the load with a boost of power), but cannot deliver that energy for a long period of time like a battery can. An ideal energy storage network will leverage both batteries and supercapacitors. Unfortunately, there is generally only space to add one or the other. This is because traditional supercapacitors are restricted to use on printed circuit boards, which take up too much space. The CBC addresses this engineering tradeoff challenge by adding supercapacitors inside the product or system's wiring infrastructure.
As a result, the flexible and wire-shape form factor of the CBC innovation creates a discrete and distributed network of power storage. |

| We developed a unique process for transferring a high-temperature superconductor (HTS), YBCO, on a metal or dielectric support. For the air-born applications, the metal can be aluminum or an aluminum alloy, which would deliver a light-weight, robust cable with the highest ampacity/weight ration for any know materials. Additionally, we developed a process for parallel slicing the cable into 1 mm filaments. This is important for reducing the magnetization loss in an AC system.
We are looking for an integration partner. |

| Power systems for hybrid and fully electric aircraft propulsion come with challenging design constraints that did not exist previously, nor do they exist in traditional electrical power grid and transportation asset applications. High-efficiency, low-weight, and highly resilient components are the hallmark of a successful aircraft power system to enable the payload, speed, and range requirements for a specified aircraft design. The weight and space implications of the power system have the potential to change the structural design and thus the performance of the aircraft.
The power capacity of the system dictates that the electrical and electronics devices would need to operate in the medium voltage range, at levels never experienced before in aerospace applications, with hybrid DC and AC voltage supply using broadly power electronics converters that operate at very high frequency and fast switching.
This type of electromagnetic environment will generate unpreceded stress conditions on any type of electrical and electronics insulation that can likely cause accelerated aging and premature failure (a note: insulation breakdown is the main cause of electrical component failure), thus affecting aircraft reliability and, of course, safe operation.
Insulation system must be then designed to withstand high electric fields and temperatures, and to provide relatively long life at extremely low failure probability, to reduce weight and cost of excessive redundancy. Shields and conductor must be optimized in terms of effectiveness, losses, weight.
These are especially challenging requirements given the types of electrical, thermal, mechanical and environmental stresses and aging factors the insulation systems of the various electrical and electronics components have to withstand.
The team at CAPS-FSU has long term experience of materials, aging mechanisms and models, diagnostics under any type of waveform, having had international recognition on such fields especially at the time prof. Gian Carlo Montanari, now at CAPS, was working at the University of Bologna. A significant amount of expertise is indeed in power cables, from MV to EHV, including AXC, Dc and power electronics supply. Nanostructured polymers, statistical and artificial intelligence algorithms, life models, health conditions assessment, measurement of properties bringing to accelerated aging, as pace charge and partial discharges, belong to the team expertise. |

He has over 30 years of academic, industrial, and entrepreneurial experience in the field of power electronics, power semiconductor devices, and energy systems. He has published around 300 papers and 18 U.S. patents in these areas. He is a Fellow of IEEE and a Fellow of the U.S. National Academy of Inventors.
He is actively engaged in solid-state circuit breaker research and is the inventor of several patents on SSCB or hybrid circuit breakers, and an author of 20 publications on the subject. He is serving as the PI of an ARPA-E CIRCUITS project on developing intelligent solid-state circuit breakers (breaker) for both DC and AC power distribution systems, including a 380VDC/20A iBreaker for DC data centers, a 120VAC/10A Smart Plug 2.0 providing fire and shock protection for consumers, and other iBreakers. In particular, his group is developing a SiC-based 750V/250A passive-cooling intelligent SSCB for a hybrid-electric aircraft which offers microsecond-level short-circuit protection, switching-mode soft precharing of DC link capacitor for the propulsion inverter, arc and ground fault detection, and hardware redundancy for aerospace applications. The SSCB iBreaker connects or disconnects the li-ion battery under nominal or overcurrent condition (in both charge and discharge directions) and offers 1000X faster response and 5X lower fault current stress, thus safer and longer lifetime for all system assets (battery, power electronics, cables, connectors, and everything else) than the existing electromechanical contactor solution. It has less than one-milliOhm on-resistance and a sufficiently low conduction loss allowing passive cooling. This electric aircraft SSCB is scheduled for inflight testing later this year.
He is also a co-PI on ARPA-E BREAKERS project on developing 6kV/200A hybrid circuit breakers based on a transient commutation current injection concept that his team invented. |
