2. Overview
This presentation will provide innovative ideas on harnessing renewable energy, decentralized and conservation of energy.
Objective is to provide healthcare, cost effective solutions, ease of mobility and reduce in low emission of carbon.
Focus point are on both renewable sources and conservation of energy.
With renewable energy, environment will be protected.
Along with the conservation of energy, the energy usage will be more efficient.

3. Decentralized Energy All interconnected to a smart Grid
Decentralized smart grid
A computer-based remote control and to bring utility electricity delivery systems.
Information from power plants and wind farms all the way to consumers of electricity in any buildings (omnidirectional).
Thus, reduced use of inefficient generation to meet system peaks
Reducing operational cost
Increased capability to integrate intermittent renewable resources
Liquid Metal Battery
Placed at decentralized micro grids at residential, commercial and industrial areas for renewable energy storage
address the problem of intermittency of renewable energy supply
Cheap, reliable and long lasting with capacity of 2 Mega Watts
Stackable for more storage
To prevent the chances of shortages of power supply.

4. Decentralized Energy Solar energy Wind energy Solar Cogeneration
captures up to 75% of the sun’s delivered energy
integrates silicon PV cells, concentrating planar optics with single-axis tracking
innovative thermal transfer system
low-cost and scalable design
Applicable to roofs of buildings(residential, commercial and industrial)
Normal Solar PV panels
Normal PV panels which has highest of 22% can be used on street lamps and windows
Government benefits of Fit-in Tariffs rate for electrical bills.
Wind energy
using 30 blade designed wind harvester
Proposed: Eco Whisper Turbine325 (for residential)
Eco Whisper Turbine 650 (for commercial and industrial)
Lowest noise wind turbine, efficient for low wind power,
Build in array/ school of fish purpose.
30% more power than a three blade Horizontal Axis Wind Turbines(HAWT)
Can be mounted on top of building itself with the low noise effect.(decentralized)

5. Conservation of energy
Under Floor Air Distribution (UFAD)
20%-30% of total energy savings vs. overhead HVAC (energy saving)
Low mixture between hot and cold air. (energy efficiency)
Reduce life cycle costs. (cost saving)
Improve indoor air quality. (healthcare)
Thermal comfort and layout flexibility.
Applicable to residential, commercial and industrial sectors.

6. Conservation Natural Lighting LED applications Greenery walls
Reduce lighting supply by 50% during day time
Applicable to each residential, commercial and industrial sectors.
LED applications
80% power supply reduction compare to normal down lights
Applicable to residential, commercial and industrial sectors
Example: Street lights with solar power
Greenery walls
Plants on the wall of buildings
Heat reduction
Carbon footprint recycling
High sound absorption coefficient
Leaf area provides shading (leaf area density)
Applicable to all residential, commercial and industrial building.

7. Conservation 88kJ of energy can be saved for every kg of water!!
Hot water piping systems
Purpose: To reduce the energy required to heat up room temperature water due to heat exchange.
Material: Heat insulation material (lower heat loss)
Transfer hot water from unwanted areas to nearby boilers
Applicable in commercial and industrial areas
Amount of heat required to raise temperature of water :
Q = m*Cp*T
Q = amount of heat needed in kJ
M = mass of water in kg
Cp = specific heat of water in kJ/kg·K
T = Difference between final and initial temperature of water
When temperature difference, T, is smaller, Q needed is lesser.
1kg of water
Room temperature, 24°C
Hot water 45°C
100°C
Q required = kJ
Q required = kJ
88kJ of energy can be saved for every kg of water!!

8. Solid Waste Management
Central Waste Handling Facility
Handle waste separation
Air from rubbish are filtered and deodorized before releasing to the atmosphere
Recyclable rubbish are compacted and sent to recycling center
Organic rubbish are converted into biogas and fertilizer.
Uses hybrid/electric garbage transport trucks
Definition
To manage the solid waste systematically with healthcare and mobility issue concerned
Benefits
Reduce traffic blockage
Reduce CO2 emission by 90%
24/7 reliability computer controlled
Clean air
Decentralized application for residential, industrial, commercial areas
Garbage chutes
-Pathway for garbage to be dropped
-500mm in diameter
Transport Network
Pneumatic system
Convey solid waste to Centre travels at 80 km/h
2.5 km max distance from collection point to Centre
pipe network runs parallel with the other infrastructure services

9. Wastewater management
Decentralized Urban Resource Recovery System
No-mix vacuum toilet
Saves up to 90% of water as compared to conventional toilet
-Using no mix vacuum toilet, 0.2 litres of water required for flushing instead of the usual 4 to 6 litres
-saves about 160,000 litres per year
Maximizes the recovery of nutrients and energy from yellow and brown water
Bioreactor to extract methane and convert it into electricity.
Diverts the liquid waste to a processing facility where components used for organic fertilizers
Grey water will be released into drainage system where it will be treated
leftover food detected are sent either to the bioreactors or turned into compost and mixed with soil, resulting in a complete recovery of resources
Treating mixed waste is energy intensive and not cost-effective, No mix vacuum toilet is thus the better solution.

10. Mobility
Electrical or hybrid vehicles should be widely implemented
Reduction on emission of pollutants (carbon monoxide)
On-Line electric vehicle (OLEV) can be used
Electrical bus has own Bus Rapid Transit (BRT)lane
Avoid road congestion
Can be provided by:
Public transport company
Industrial company for staffs
Benefits: Reduce pollutions, reduce the usage of un-renewable energy sources (petroleum),
-On-Line Electric Vehicle(OLEV) can be wirelessly charged on the road.
-Has devices built in under the vehicle to harness the magnetic field generated by power cables under the road
-Magnetic wave is then converted into electricity for EV operation.
-Zero extra time is required for recharging the battery as the OLEV can be charged while driving on the power line.
-No special facility needed and can scale down battery size
-Recycle of waste wave and no emissions of carbon footprint

11. Further Futuristic Planning
Implementation of higher efficiency solar panels
Highest efficiency available triple junction solar cell is 44% (aerospace usage)
Current highest efficiency panel on market is approximately 22%
Harnessing waste electromagnetic wave at higher scale
Current technology with low voltage output can only charge and power up small power load.
Implement the usage of “Saphonian”
Zero-Blade Non-Rotational Wind Converter
2.3 times the efficiency of normal 3 blade wind turbines
Significant Cost Savings (Costs 45-50% less than conventional wind turbines)
