This study analyzed reducing electrical loads in idling long-haul trucks through improved cab insulation and orientation. Simulations of various cab configurations in 161 US cities found:
1) Facing north during rest periods can reduce annual cooling loads up to 26% while increasing heating loads up to 11%.
2) The most insulated cab configuration reduced annual cooling loads up to 55% in western cities and 40% in eastern cities, while reducing heating loads up to 35% in northern areas and 26% in southern areas.
3) This optimally insulated configuration required only around 10 kWh of battery power annually, allowing trucks to eliminate idling solely for air conditioning.

Noaman_MasterThesis_Abstract
The document discusses concentrating solar power (CSP) tower plants and novel high-efficiency thermodynamic power cycles. It analyzes the Supercritical-CO2 closed Brayton cycle with recompression and compares it economically against the mature Rankine cycle under different solar tower configurations. A base-load power plant was simulated for the two cycles with a 3 solar-multiple setup to achieve a 70% capacity factor. Exergy analysis showed around 71% efficiency for the recompression S-CO2 closed Brayton cycle at 900°C, while economic analysis found levelized costs of electricity of $0.11/kWhe for the Rankine cycle and $0.105/kWhe for the S-CO
Steam powered robots
The document presents a monopropellant-based approach for powering steam-powered robots. It discusses how monopropellants can provide higher energy density than batteries. The approach uses hydrogen peroxide decomposition to produce steam for pressurizing reservoirs and powering actuators. Experiments on a prototype actuator showed a maximum conversion efficiency of 6.6%, which was limited by heat losses. Insulation improved the efficiency to 9%. The approach offers higher actuation potential than battery-powered systems but has limitations including heat losses, cost, and safety issues. Further development could improve performance and make monopropellant systems a viable option for powering robots.
Micro Wind Turbine paper
This document summarizes a study that evaluated the performance of micro wind turbines installed at an experimental housing development called the EcoSmart Show Village over a 12-month period. Five micro wind turbines of two different models were tested under real-world conditions. Measured outputs were lower than theoretical outputs, likely due to turbulence from the urban environment and inefficiencies in the inverters. Factors like lateral turbulence and inverter consumption need to be considered to accurately assess the potential output of micro turbines in built-up areas.

Selection of prime mover type was investigated for use in combined cooling, heat and power systems. Selection was determined from comparison of performance criteria for economic, energy and emissions savings. Simulations were run for three different types of prime movers in one climate zone and compared to a reference case with a typical separate heating and power system in the same climate zone. A hybrid load following method was implemented, with a suggested improvement. Performance parameters were compared and results indicated emissions and energy savings for all three prime movers. The prime mover types were reciprocating internal combustion engine (ICE), micro-turbine and phosphoric acid fuel cell. The climate zone was chosen to be a cold, humid climate represented by Chicago, IL. Economic savings were seen for both the ICE and micro-turbines. Emissions savings for carbon, nitrogen oxides and methane, for all three types, were greater than 9%, 12%, and 13%, respectively. Primary energy consumption savings for all three were greater than 8%.Steady state mathematical modeling of solid oxide fuel cell for hybrid system...

Environmental Profiles for Motors and Transformers
Highlights:
* The principal life-cycle environmental impact of motors and transformers is climate change.
* Operational power consumption contributes most to climate change.
* Any improvement of motor efficiency will benefit the environmental profile of the equipment.

Sam Chapman | Electricity Sensitivity
The document discusses different methods of carbon accounting for electricity production from nuclear, coal, and wind sources. It finds that nuclear power is currently the most sensitive to carbon accounting due to uncertainties and assumptions that must be made. Standardizing carbon accounting methods and reducing uncertainties could help improve comparisons and identify opportunities to lower carbon emissions from electricity generation. Opening debate on accountability and establishing clear system boundaries are important to better understand emissions over the full life cycle of energy projects.

This document presents a mixed integer programming approach for the yearly scheduling of a mixed hydrothermal power system. The model schedules thermal generating units on an hourly basis while considering reservoir levels and pumping operations for hydro units on both an hourly and monthly basis. The objective is to minimize total annual thermal generation costs given load predictions and constraints for the power balance, reserve requirements, and hydro plant and reservoir operations. The model is tested on a power system based on Greek electricity data from 2004 consisting of 29 thermal units totaling 6.9 GW of capacity and 13 hydro plants with 3 GW of capacity.

Space vector modulation (SVM) technique for CSC is established by dividing ac-side line current cycle into six sectors. Each sector is divided into certain number of space vector (SV) cycles. SV cycle is divided into three states, two active and one zero state. SVM technique generates fifth and seventh harmonics (HD5-7) in the CSC ac-side current when operated with low switching frequencies, i.e., low number of SV cycles. Minimal reduction in HD5-7 was achieved by using certain states sequence inside SV cycle, and by calculating states ON times at once in the middle of each SV cycle. In this paper, fuzzy logic-dependent technique for calculating states ON times in SVM-CSC is proposed.A Hybrid Cooling System for Telecommunicatioin Base Stations
Huge amount of energy is consumed by a typical telecommunication base station in order to keep the indoor
climate temperature low enough to avoid any damage to
IT/electronic equipment. By increasing the number
telecommunication base stations applying more energy efficient
cooling strategies are urgently needed. Free cooling either in
direct approach (e.g. extracting fresh air), or indirect approach
(e.g. thermosiphon or air to air heat exchanger) is a well-proven
strategy to reduce the total power consumption for cooling
telecommunication base stations. This presentatioin proposes a hybrid cooling system, which is an integrated vapour compression unit with a thermosiphon unit in a single frame. In such a hybrid system the indoor air circulates through a closed loop with minimal interaction with the outdoor air.
Hydro-Thermal Scheduling: Using Soft Computing Technique Approch
This document summarizes three techniques for optimizing generation costs in a hydro-thermal power plant system: classical method, genetic algorithm, and differential evolution method. It describes applying each method to a sample system with one thermal plant and one hydro plant over a 24-hour period. The classical method uses linear programming to minimize costs. The genetic algorithm and differential evolution method are evolutionary optimization algorithms inspired by biological evolution. They are found to provide better results than the classical method by evolving solutions over multiple generations.

The document presents a combined power and cooling cycle using aqua-ammonia vapor absorption refrigeration. It compares typical refrigeration cycles to the proposed Goswami and Srinivas cycles that allow for combined power and cooling output. The proposed cycle uses aqua-ammonia as the working fluid and includes formulations to calculate the net work, efficiency, power output, and cooling output of the cycle. Simulation results show the cycle can produce additional power while doubling efficiency compared to typical cycles. The cycle offers flexibility to produce only power or combined power and cooling, and is suitable for various atmospheric conditions.

The document summarizes a study that simulated a 620 MW natural gas combined cycle power plant using Aspen Hysys software. It determined the optimal flue gas recirculation ratio by investigating the effect of recirculation on carbon dioxide and oxygen levels in the exhaust gas. A ratio of 0.42 was found to increase CO2 levels to 9.2% while decreasing O2 to 3.5%. The study also found this ratio increased the plant's overall efficiency from 57.5% to 58.2% by more than the cooling effect on combustion turbine power. Exergy and environmental impact analyses determined the combustor had the lowest exergy efficiency of 75.65% and highest environmental impact contribution of 20.74
HYDROTHERMAL COORDINATION FOR SHORT RANGE FIXED HEAD STATIONS USING FAST GENE...
This paper presents a Fast genetic algorithm for solving Hydrothermal coordination (HTC) problem.
Genetic Algorithms (GAs) perform powerful global searches, but their long computation times, put a
limitation when solving large scale optimization problems. The present paper describes a Fast GA (FGA)
to overcome this limitation, by starting with random solutions within the search space and narrowing
down the search space by considering the minimum and maximum errors of the population members.
Since the search space is restricted to a small region within the available search space the algorithm
works very fast. This algorithm reduces the computational burden and number of generations to
converge. The proposed algorithm has been demonstrated for HTC of various combinations of Hydro
thermal systems. In all the cases Fast GA shows reliable convergence. The final results obtained using
Fast GA are compared with simple (conventional) GA and found to be encouraging.

This paper proposes the modified Gravitational
search algorithm (GSA) to solve short term multi chain
hydrothermal scheduling problem while satisfying all
operational and physical constraints. The effect of the valve
point loading has been considered. Gravitational search
algorithm is based on the Newton’s law of gravitation. All
objects attract each other and global movement is towards
the heavier masses .However GSA has certain randomness
in search direction resulting in the weak local search ability.
In modified GSA, a time varying maximum velocity equation
is used which controls the exploration and improves the
convergence rate which strengthens its local search ability
and the quality of the hydrothermal solution.

awr.2016-article-health-care-costs-still-breaking-the-bank
The document summarizes the findings of Aflac's 2016 WorkForces Report on employee benefits and attitudes. It finds that 65% of employees have less than $1,000 available to pay for unexpected medical costs. Healthcare costs continue rising, as the average worker spent $132 more on family health insurance in 2015. Many employees report being unprepared for out-of-pocket medical expenses and would use credit cards or borrow to pay costs. The report also examines benefits trends like concerns about costs being shared across all demographics and millennials being less informed about costs than other generations. It concludes voluntary insurance can help offset costs not covered by major medical to give employees more robust coverage.

This document compares the efficiency of subcritical and supercritical pressure in thermal power generation. Supercritical pressure refers to pressure above the critical point of water at 374°C and 22.1 MPa, allowing steam to reach higher temperatures without changing phase. The document finds that supercritical units have higher efficiency (52-59%) than subcritical units (36-37%) due to higher steam parameters, reducing fuel consumption and emissions. Major power companies worldwide have adopted supercritical technology, and India is planning supercritical projects to improve efficiency and meet increasing energy demand.

The document describes the design and computational fluid dynamics (CFD) analysis of a centrifugal compressor and radial inflow turbine for a supercritical carbon dioxide power cycle. The authors developed in-house software to perform meanline design of the compressor and turbine considering fluid properties and loss correlations. They then analyzed the designs using CFD software. Key results include achieving 80% isentropic efficiency for both machines and reducing compression work to 50% compared to ideal gas compression. The CFD analysis implemented real fluid properties and investigated flow behavior near the critical point of CO2.
Magneto hydro dynamic system
This document discusses magnetohydrodynamic (MHD) power generation. MHD uses electrically conducting fluids to directly convert heat into electricity in the presence of magnetic fields. It has the potential for higher efficiencies than traditional steam plants. There are two main types of MHD systems - open cycle systems which exhaust hot gases directly and closed cycle systems which recirculate the working fluid. MHD systems avoid moving parts but developing the high temperature fluids and magnetic fields presents design challenges. The technology could allow more efficient, pollution-free large-scale power generation if these problems are addressed.

Gas turbine exergy analysis
The document summarizes an exergy and exergo-economic analysis of the Montazer Ghaem gas turbine power plant in Iran. The analysis finds that the combustion chamber has the highest exergy destruction due to the large temperature difference between the flame and operating fluid. The gas turbine's performance and efficiency are significantly affected by ambient temperature. An increase in ambient temperature decreases the net power output and exergy efficiency. The exergo-economic analysis determines that the combustion chamber also has the largest cost of exergy destruction.
