Researchers have built a lab-scale prototype of the thermal water pump system, with early tests showing the system can produce 1000L of freshwater from 2000L of saline feedwater with a salt concentration between 5000–15,000 grams per cubic metres. The system works by boiling a refrigerant at constant temperature and using the pressurised refrigerant vapour to power a piston and pump water out. To suck water in, the vapour is cooled down, reducing the volume, pushing the piston in the opposite direction. “The success of this project will provide a much needed alternative system that can be manufactured in Australia and provide opportunity for industry development, employment creation and export,” Dr Date said. Dr Date is a Lecturer in the School of Aerospace, Mechanical and Manufacturing Engineering at RMIT. ACQUA FOR LIFE AND GREEN CROSS PROVIDE AID IN ARGENTINA Acqua For Life together with Green Cross International provides millions of litres of safe water each year by building wells, rainwater harvesting systems, boreholes and water pumps. The first Acqua for Life initiative in Argentina will focus on the Chubut Province of Patagonia, a region stricken with poverty and a harsh climate. A 300-metre-deep water well will be built in a community near Gastre to secure the local water supply and irrigate a greenhouse facility growing fruits and vegetables all year round. During 2015 Green Cross will also use Acqua for Life contributions to support new infrastructure developments in Africa (Ghana, Ivory Coast and Senegal), China and elsewhere in Latin America (Bolivia and Mexico). The campaign has been brought to new countries in three continents since 2011. Green Cross and Acqua For Life ambassador Giorgio Armani will continue to raise awareness of water poverty in developed and water-rich countries throughout 2015, while carrying out on- the-ground projects to supply deprived communities with secure, safe and sustainable water. To help spread the word about the preciousness of clean, safe water, Acqua for Life 2015 is challenging key bloggers, media and online personalities to try to live on just 10 litres of water for one full day. In most countries, people use an average of 100 litres of water every day but in some parts of the world having just 10 litres is a luxury. This challenge will see a number of prominent people document their experience and educate their followers about water poverty and the importance of having reliable access to clean water. The #1DayOn10Liters Challenge kicked off on World Water Day, 22nd March 2015. The challengers’ experiences can be followed via the hashtags #1DayOn10liters #Helpgivewater #Acquaforlife and on the official website www.acquaforlife.org CITY OF SYDNEY’S ENERGY EFFICIENCY MASTER PLAN A new City of Sydney master plan for energy efficiency aims to show businesses and residents how to slash greenhouse pollution and save more than $600 million in energy bills by 2030. The Plan could make Sydney one of the world’s most energy-efficient cities and provide a major contribution to achieving the City’s goal of reducing carbon pollution 70 per cent below 2006 levels by 2030. The draft Energy Efficiency Master Plan includes a comprehensive analysis of all buildings in the City of Sydney area and shows how energy use in homes and offices could be reduced by more than 30 per cent. The analysis, conducted by energy experts pitt&sherry, shows how to improve the efficiency of buildings (including the City’s own properties), commercial office space, and residential blocks and accommodation. The action would slash nearly two million tonnes of carbon emissions a year city-wide by 2030, a 33 per cent reduction from 2006 levels and nearly half of the reduction the City is committed to in Sustainable Sydney 2030. The City will send the Plan to all other Australian capital cities so that they can use it as the basis for similar plans. Lord Mayor Clover Moore said the time for action on climate change is now and while many governments are doing little, the City is already delivering and demonstrating significant action. “Cities make up two per cent of the earth’s surface but they account for 80 per cent of carbon emissions, so action in cities is essential. In the face of inaction from the Federal Government, we’re calling on other Australian cities to pick up our plan and help us get on with the job of tackling climate change. “By improving energy efficiency through the actions and technologies outlined in the plan our residential and business communities can also reduce costs. The research in the plan shows building owners and their tenants just how much can be saved on power bills by reducing energy use. This would save millions of dollars and improve economic growth while significantly reduce greenhouse gas emissions.” The plan aligns with the NSW Government’s NSW Energy Efficiency Action Plan to improve energy productivity and remove the barriers preventing people from saving energy.
