User innovation in sustainable home energy technologies
Users in Finland have invented modifications and improvements in three key home renewable energy technologies: heat pumps, wood pellet systems, and ground source heat pumps. Over 100 user inventions were identified across the different technologies, though few were truly novel innovations. Most improved existing systems in ways that increased benefits for individual users but had drawbacks that made them unsuitable for mass production. User innovation capitalized on locally applicable customizations. While highly concentrated among a small number of active users, implications include examining user inventions to proliferate solutions and involving lead users to support technology development and market creation.
ES&T - HDD as GSR Feature
1) Horizontal directional drilling (HDD) is more sustainable than traditional vertical drilling methods for installing soil and groundwater remediation technologies, as it reduces energy usage, air pollution, and environmental impacts during both construction and long-term operation.
2) A case study using modeling tools found that installing a single long horizontal well to capture a contaminant plume would produce lower air emissions than 12 shorter vertical wells, due to reducing the amount of drilling, equipment, and materials needed.
3) Key sustainability benefits of HDD include reducing construction time and equipment usage, needing fewer smaller pumps and blowers to operate remediation systems, and limiting disturbance to surface infrastructure and habitats.

16-05-25 Maynard--RSES Journal
The Union County Public Schools in Tennessee recently completed an HVAC retrofit project at four schools using a custom unit ventilator system combining variable refrigerant flow (VRF) technology with an enthalpy wheel for energy recovery. The system was designed to meet the schools' need for outdoor air ventilation while significantly reducing energy costs compared to the old window units and radiators. Each classroom unit ventilator supplies 350-400 CFM of conditioned outdoor air integrated with a VRF system and enthalpy wheel for heat recovery. Initial results indicate the system will more than double the energy efficiency of the old system and provide payback through annual energy savings. The project team hopes this innovative system will revolutionize school HVAC retrofits

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

- 1. LOW FLUSH TOILET GROUP 8 DESIGN PROJECT
- 2. MODERN TOILETS The modern toilet though innovative and efficient in getting rid of waste uses quite a lot water . This in turn causes the following: Increase in water bills Misuse in investment put in cleaning/recycling High cost of living Due to the problems stated above, the group members were tasked with coming with a flush toilet concept that reduces water consumption.
- 4. (problem is here) water(material) mechanical (energy) EMS MODEL WITH TRIZ COMPONENTS LEVER HANDLE LEVER ARM FLAPPER BOWL TRAPWAY SEWER FILL TANK FLOAT BALL INLET VALVE
- 5. CUSTOMER NEEDS ● According to the results of a questionnaire made by the group members the following needs were found to be common among a multitude of customers. They are; water efficiency, cost, aesthetics and user friendliness. ● An AHP was drawn up by the team in order to weight and find out the most immediate need to be met. ● The following was the order of importance according to the AHP: water efficiency, convenience, cost, aesthetics.
- 6. EXTERNAL SEARCH ● An external search (patents) was conducted in order to find out existing toilet designs that conserve water so as to come up with new concepts or improve on already existing ones. An art- function matrix was drawn.
- 7. IDR AND TECHNICAL CONTRADICTIONS ● IDR( IDEAL FINAL RESULT) A resource that will eliminate use of excess water which leads to leads to misuse of resources that are put in water recycling, within the toilet during flushing without complicating the system while the toilet is getting rid of waste. ● TECHNICAL CONTRADICTIONS Complexity of the design (36) verses productivity (39) Productivity (39) verses water quantity (26) Stress or pressure (11) verses quantity of water (26)
- 8. GENERAL SOLUTIONS FROM CONTADICTION MATRICES ● From the technical contradictions deduced a contradiction matrix was drawn up. Using the TRIZ appendix further helped the team members to base their concepts on the design principle solutions proposed by the TRIZ appendix. ● DESIGN PRINCIPLES 3-Local quality 17-Moving into a new dimension 35-Altering an object’s aggregate state 10-Preliminary action 24-Go between 36-Use of phase changes 12-Equipotentiality 27-In-expensive short life 38-Using strong oxidation agents 13-Opposite action 28-Replacement of a mechanical pattern 39-Using an inert atmosphere 14-Spheroidality * 29-Hydraulic or pneumatic solutions
- 9. CONCEPT GENERATION CONCEPT 1 CONCEPT 3
- 10. CONCEPT GENERATION SIDE VIEW OF CONCEPT 2 TOP VIEW OF CONCEPT 2
- 11. CONCEPT SELECTION ● We used the help of Pugh charts to obtain our final design from our three concepts. Concept three was the best since it was the one with the highest total whenever it was used. This was followed by concept two. And finally concept 1. We decided to use concept 3 since it was the best.
