The financial,
environmental, and national security carrot for a Return to the Moon consists
of access to low cost lunar helium-3 fusion power. Helium-3 fusion represents an
environmentally benign means of helping to meet an anticipated eight-fold or
higher increase in energy demand by 2050. Not available in other than research
quantities on Earth, this light isotope of ordinary helium-4 reaches the Moon
as a component of the solar wind, along with hydrogen, helium-4, carbon and
nitrogen. Embedded continuously
in the lunar dust over almost four billion years of time, concentrations have
reached levels that can legitimately considered to be of economic
interest. Two square kilometers
of large portions of the lunar surface, to a depth of three meters, contains
100 kg (220 pounds) of helium-3, i.e., more than enough to power a 1000
megawatt (one gigawatt) fusion power plant for a year. In 2009, helium-3's energy equivalent
value relative to $2.50 per million BTU industrial coal equaled about $1400
million a metric tonne. One
metric tonne (2200 pounds) of helium-3, fused with deuterium, a heavy isotope
of hydrogen, has enough energy to supply a city of 10 million with a year's
worth of electricity or over 10 gigawatts of power for that year. The initial financial
threshold for a private sector initiative to Return to the Moon is low: about
$15 million. This investment
would initiate the first fusion-based bridging business, that is, production
of medical isotopes for point-of-use support of diagnostic procedures using
positron-emission tomography (PET).
Other terrestrial applications of helium-3 fusion technology prior to
reaching sustained power production exist as well. The entrepreneurial private sector has an obligation to support a return to the Moon to stay. We also have an obligation to follow our own path to get there in order to be additive to the overall goals of settling the Solar System and improving lives for those who remain on Earth. Traversing that path, with an ideally funded business plan, would require about $15 billon and 15 years. |

Challenges,
Opportunities and Innovations in Wind Power Recovery Systems |
Dr. Majid
Rashidi |
Cleveland State
University |

An innovative wind harnessing system has been designed and developed at Cleveland State University. The system is designed for harnessing wind energy at relatively lower wind speeds where conventional windmills do not operate efficiently. The system includes a wind speed amplifier structures. The structure increases wind velocity on its approach to standard horizontal-axis wind turbines. According to the Bernoulli principle the wind amplifier structures increase the ambient wind speed, resulting in a higher power output and lower cut-in ambient wind speed for the standard turbines. This design concept is aligned with the small distributed wind energy systems initiative of the DOE that is aimed for conversion of wind energy into electricity at geographic sites where the wind speed is relatively low. The system is adaptable as a retrofit to the existing cylindrical structures such as water towers and silos. A fully functional prototype of the design has been fabricated and installed on the rooftop of the Physical Plant Building at Cleveland State University. The name-plate-rating of the system is 8 KW. The system has an active yaw control mechanism that orients four turbines into the prevailing wind. The electricity generated by each turbine is conducted to a multi channel junction box via a multi-channel high power slip ring. Each turbine has its own inverter unit that converts the generated power from DC to AC power with adjusted phasing. The AC power is then fed into the Plant Service Building at CSU. Preliminary experimental data shows that the energy produced by a single standard turbine incorporated into this proposed wind tower system is increased by a factor or 3 to 4 folds compared to the same turbine under the same wind conditions. |

Hydrogen
Fuel Cells Applied to Mobile Ground Support and Materials Handling Equipment |
Mr. Frank Jakob |
Battelle
Memorial Institute |
|
Systems engineering is required to ease the path to implementation for non-carbon (hydrogen) based vehicles. Lacking a hydrogen infrastructure, one-off demonstrations are doubly difficult to accomplish because both the fuel-cell device and the hydrogen refueling infrastructure have to be provided. This presentation will discuss the benefits of concentrating the density of fuel-cell vehicles use as a means of enabling affordable hydrogen refueling for those multiple devices. This applied systems approach increases the number of implementations for fuel cells in vehicles. In particular, the conversion of propane and/or battery powered materials handling equipment (fork lifts, aircraft tow tugs, etc.) can be shown to have paybacks for sufficient concentrations and usage duty-cycles for those vehicles. |

The
Grid of the Future: A Systems Approach to Achieving Stability and Security |
Dr. Ken Loparo |
Case Western
Reserve University |
|
The development and deployment of alternative energy resources, e.g. solar and wind, will be required to meet future demands for electricity while reducing greenhouse gas emissions and carbon footprint. Because these energy resources will be highly distributed with intermittent availability and capacity factors that can be significantly below that of a conventional power generating plant, the effective integration of these systems into the grid to maintain stability, security and operational reliability is a challenging problem that requires a systems approach. |

Passive
House: The World’s Most
Demanding Energy Efficiency Standard |
Mr. Mark
Hoberecht |
National
Aeronautics and Space Administration, Glenn Research Center |
|
The Passive House
standard represents a paradigm shift in residential construction by saving nearly
90% in heating/cooling costs over conventional homes. These homes rely mostly on
“passive” solar orientation and “passive” heat gains
from people, appliances, consumer electronics, etc. Any remaining heating/cooling loads
are typically met with very small supplementary systems, such as
room-specific radiant heaters and ductless mini-split systems. Conventional furnaces and even
geothermal systems are oversized and therefore unnecessary in Passive Houses. All Passive Houses are characterized by
super-insulation, high performance windows and doors, virtually air-tight
construction, and energy-recovery ventilation. Not only are these homes energy
efficient, they also provide exceptional health and comfort. Over 15,000 projects in Europe, from
the Mediterranean to Scandinavia, attest to the viability of the Passive
House. The standard has been so
successful that several European countries are now considering making Passive
House the minimum code requirement by the middle of the next decade. |

System
Engineering: 12 Essential Practices for System Development Success |
Charles Wasson |
Wasson
Strategics, LLC |

Organizations developing
systems and products often face budgetary constraints that limit the level of
the System Engineering effectiveness. To meet this challenge, technical
programs often resort to traditional "Build-Test-Fix" methods on
the false assumption of economy and schedule knowing the methods are prone to
failure, especially on large, complex development efforts. In contrast, SE
practices tailored within budgetary constraints provide the most significant
return on investment (ROI) and improved probability for system development
success. This presentation identifies 12 System Engineering practices essential to system development success. Mr. Wasson examines each of the SE practices as contributory performance effecters that provide the greatest ROI for achieving technical program success and improving SE effectiveness. Topics include: requirements analysis, allocation, lowdown, and traceability; system architecture selection and development; interface definition and control; complexity management; model-based system engineering (MBSE); baseline management; SE metrics; verification & validation (V&V); et al. |

Organizations and
project teams must comply with an increasing number of process management and
documentation requirements. This is especially true in the medical device,
DoD, government, and commercial sectors where the design and development of
products and systems is regulated or bound by stringent contractual
obligations. Without careful consideration to data and information management
efficiency and quality, compliance to these requirements can be very
burdensome and costly. This paper presents an
integrated process/data management architecture that achieves compliance
while improving efficiency and effectiveness of the requirements, risk,
verification and validation processes. This is accomplished by eliminating
redundancy of data and tasks, ensuring traceability, enhancing communication
and understanding, and facilitating rapid learning. The system is complete
and closed loop, which ensures ease of compliance demonstration and
facilitates ease of creating error-free documentation. It is adaptable to
different levels of system complexity and hierarchical structures and enables
metrics on project deliverables. It is reusable and maintainable throughout
the system full life cycle, speeds the design & development process, and
better ensures satisfaction of customer requirements. |

Framing
the Question; Key to Understanding Stakeholder Expectations |
John R.
Chiorini, Ph.D. |
The Center for
Systems Management |
|
Top level requirements
and the associated acceptance criteria make the assumption that we understand
the stakeholder’s expectations of success for a project. Helping the
stakeholders frame their problem and in fact selecting the proper frame to
begin questioning stakeholders about their expectations is a key step in
defining the problem and its candidate solutions. I recommend understanding
the “cloud of expectations” before stating acceptance criteria
and their associated top level requirements. |

Modeling, Simulation and Analysis of Integrated Multi-Disciplinary
System of Systems |
Dr. Eric A.
Walters |
PC Krause and
Associates, Inc. |

PC Krause and
Associates, Inc. (PCKA) is a high-tech consulting firm that has been involved
for more than two decades in modeling, simulation and analysis (MS&A)
focused on modern aircraft/spacecraft systems, which contain various
components and subsystems. These typically include electromagnetic,
electromechanical, aerodynamic, prognostics and health management, and
thermal management subsystems. Often the models of the components/subsystems
are of differing levels of fidelity and developed using simulation
tools/languages that are discipline-specific. During the various stages of
system design, it becomes desirable to connect these models to form an
integrated (system of systems) simulation. Such integrated MS&A capability
is essential to ensure that the design and system-level optimization
requirements will be satisfied. PCKA has developed several custom software
tools to augment popular commercial-off-the-shelf software simulation
packages in order to meet its customer’s needs. These tools have been
applied to several notable DoD development programs, particularly in the
areas of More-Electric and Energy-Optimized Aircraft. In this presentation, a
brief overview of some of PCKA’s tools is provided while highlighting their
impact on such programs. |
