Flexible Integrated Transportation System for Commuter (FITSCommute) Services (CU18376)

Ride-sharing is often a cheap and time-efficient method for people to commute or travel. However, finding a good match between riders and drivers is difficult due to the complexity in computation and people dynamics. This technology describes an algorithm and software to provide a flexible ride-sharing service.

By proposing stops in advance that will go through reviewing by the users (riders and drivers), it lowers number of stops, automates and optimizes the route designs to provide a highly-efficient service. It can also be integrated with existing public transportation systems to gain access to the majority of commuters.

Manufacture and installation of a foamed concrete panel for energy efficient building envelope (CU19299)

Building envelopes serve as a substrate for both building integrity as well as for modules built onto them. Current building envelopes are not designed for photovoltaic (PV) modules, which can acquire solar energy for a building, thereby causing inefficiency in capturing energy.

This technology is a foamed concrete panel that is designed for use both as a traditional building wall as well as a substrate to increase the efficiency of PV modules. The design enables increased energy-harvesting efficiency while maintaining a low cost of manufacturing and easy installation. As such, this technology has the potential to greatly increase the effectiveness of PV modules in a multitude of building types.

Design of a geothermal well filled with phase change materials for daily and seasonal heat storage and supply. (CU19309)

Geothermal energy, the energy stored within the Earth, is a renewable and clean energy source that can be used as an alternative to traditional heating and cooling systems. This technology is an improved geothermal well that uses features in the ground to overcome the limit of heat storage capacity seen in other geothermal wells.

Method and apparatus for imaging in-place density distribution by the gamma ray. (CU19239)

Nuclear gauges measure the scattering or transmission of radiation within a material to quickly and non-destructively obtain the moisture content or bulk density. However, the use of radioactive material poses certain health risks and requires special handling, and complex calibration is necessary to correctly correlate radiation count with material properties.

show more

This technology is a system that can obtain a 3D density and moisture distribution of a material using gamma radiation and strategically placed sensors. As a result, in contrast to traditional nuclear gauges, density and moisture content can be determined directly without calibration, while still allowing for rapid measurements. Thus, this technology has the potential to increase efficiency in various engineering and industrial applications and reduce radiation exposure for nuclear gauge users.

Systems and methods for a hybrid geothermal-solar heating and cooling of pavement overlays. (CU19266)

Weather phenomena in both hot and cold climates can negatively affect the structural integrity of pavement and reduce its efficacy and safety. Currently, the most popular methods for remedying these issues rely on chemicals, salts, and machines like plows that can be expensive, destructive to the pavement, or detrimental to the environment while also not being suitable for all situations.

This technology describes a system that can regulate the temperature in pavements that uses sustainable energy sources. The system can be automated and constructed such that it efficiently dissipates heat during the summer or introduce heat during the winter. As a result, this system can be used in all different types of climates to improve safety and comfort and reduce maintenance.

A submerged wave energy converter harvesting ocean energy. (CU19114)

Ocean waves are one of the largest untapped sources of renewable energy in the world, with an estimated 2 TW available annually. However, current wave energy converters are generally inefficient and are susceptible to corrosion and biofouling in the exposed water.

WaveHouse is a submerged pressure differential wave energy converter with high energy absorbing efficiency and resistance to degradation. The structure consists of a “house” that encloses an air tank and pistons, which are driven up and down by wave motion acting on external air bags, allowing for higher amplitudes than previously available. This technology has potential applications in coastal renewable energy generation.
