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.

Overview

Decentralized EnergyAll interconnected to a smart Grid

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.

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

Solar 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)

Decentralized 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.

Conservation of energy

Natural Lighting◦ 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.

Conservation

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.

Conservation

1kg of waterRoom temperature, 24°C Hot water 45°C

100°C

Q required = 318.44 kJ

Q required = 230.45 kJ

88kJ of energy can be saved for every kg of water!!

Solid Waste Management

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

Garbage chutes-Pathway for garbage to be dropped-500mm in diameter

Benefits• Reduce traffic blockage • Reduce CO2 emission by

90% • 24/7 reliability computer

controlled• Clean air• Decentralized application

for residential, industrial, commercial areas

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

Wastewater managementDecentralized 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.

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),

Mobility

-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

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)◦ Environmental friendly
