Dr Stephen Bygrave

AN OVERVIEW OF THE WORK OF BZE OVER THE YEARS
To speak about such a topic, the guest was BZE CEO Dr Stephen Bygrave who is about to embark on a new challenge to join the Queensland government as executive director in the field of environment and climate change.

The work of BZE has encompassed such diverse areas as 100% renewable energy and how soon this may be viable, buildings, battery storage, agriculture including land clearing, industrial processes (such as alternatives in the production of aluminium), and transport to name just a few. In fact BZE has attained worldwide acclaim.

Transport in particular is responsible for 15% of national emissions but the ridiculous dependence on cars in Australia is badly in need of a "mode shift" in favour of public transport and electric cars not forgetting the movement of freight. It is so short-sighted by governments to move freight on the road in lieu of rail which had been achieved in the past. BZE has also written on the topic of high speed rail which has been utilised so successfully in other countries, in particular India and China where there are so many people to accommodate!

So Stephen will perhaps be involved in the different challenges that Queensland can throw up  - none bigger than the Great Barrier Reef and Adani and land clearing!

Prof Tara P. Dhakal

Beyond Zero speaks to Professor Tara P. Dhakal of Binghamton University, State University of New York, about his research developing high efficiency solar cells. 

Advances in the manufacture of Solar Cells

Prof Tara Dhakal started off with study of Physics and Material Science, working in Kathmandu, Nepal and Japan and later joined the Uni. of Sth. Florida with the aim of making improved thin film solar. He is at present Assistant Professor of Electrical and Computer Engineering, at the State University of N.Y. and it seems he has always been interested in applied research.

Problems of course with solar is the need to access materials that are abundant, non toxic, reliable and not only cost efficient to manufacture but to install. Approximately 25% of silicon can be converted into electricity and it is fairly expensive to process into wafers.  The Professor discussed the possibility of transparent layers for windows and/or roll-out for roofs.

Charles Rendigs

 

The reduction of extremes in heat or cold without continually increasing power consumption

The answer is provided by Charles Rendigs, the National Business Development manager of "Thermoshield", an Australian company developed and owned, situated at Dandenong. It is a coating for roofs that can be painted or sprayed on, can be coloured by mixing with  red or green paint. White of course is generally used when a high  solar reflective index is desired i.e. in Summer but as it ages its capacity to reflect is naturally diminished.

But Thermoshield can also be used to retain warmth inside in the Winter months i.e. as a form of insulation producing what is called "dead air" space so its properties can work to either reflect or absorb. It can be used in conjunction with  PV as PV usually only covers part of the roof and may heat up around the cells. It can increase the productivity of cells during the day. It can also be complementary to pink batts. air conditioners and other forms of temperature control.

It has been tested by CSIRO and has been used from Queensland to Melbourne. It sounds like a robot acting as instructed!

Prof Andrew Blakers

From Stars to the Sun

Professor Andrew Blakers is a professor engineering at the Australian National University. He works in the area of photovoltaics. His original goal was to be an astronomer studying Maths and Physics but while bushwalking  he was struck by so many places under threat - and that was as far back as the 70s!

He believes Australia receives thousands of times more solar energy than all the fossil fuels combined so why not be involved in solar and wind? He is a member of ARENA but fears the organisation, with the present political situation may lose the capacity to award grants. 

An interesting account of Andrew's life and work can be accessed on the ABC's Conversation Hour (13/6) and more details on the usual BZE podcast which mentions sliver, PERC technologies and silicon with its non-toxic properties. 

He has no doubt that Australia could become 100% renewable before long - and that is not just "pie in the sky"!

An entrepreneur in renewable energy

Chris Cooper is Chief Energy Officer and co-founder of SunCrowd, who are helping communities run local bulk-buy campaigns to make rooftop solar and storage easy and affordable. Chris Cooper became a keen clean energy student whilst at high school studying Economics and Geography and he was encouraged by gaining a Winston Churchill Fellowship scholarship which took him overseas to U.K., U.S. and Europe.  He favoured working for a practical change rather than joining academia and to concentrate in a local area.  To achieve this, he co-founded SunCrowd mainly situated in Shellharbour, Nowra and recently launched in SunCrowd Newcastle, NSW, although he has received calls from places as far afield as Alice Springs, Broken Hill and Melbourne. He finds people are keen for information on dispatch and storage of power.

Specialising on local communities seems to resonate with Germany where ownership of power has been returned to local communities. And of course in Australia with the development of rooftop solar despite the drop in feed-in tariffs. At the same time he has found problems in achieving grants and government funding and has found ARENA rather bureaucratic compared with the US which has provided millions in Government grants. ARENA seems to favour large organisations such as AGL.  Hopefully he says his submissions will change this but there is certainly room for that considering the present Prime Minister speaks regularly of "innovation"!

Tim Forcey: 22 ways to cut your energy bills

How to save money on power bills

This is a headline which should be of interest to everyone!

Beyond Zero's Kay and Michael speaks to Tim Forcey, Energy Advisor, Melbourne Energy Institute, University of Melbourne talks about 22 things you can do to improve your home’s energy performance. And how to reach the ultimate goal of a home heated and powered by 100% renewable electricity. 

My Efficient Electric Home fb group - join us!

Tim has ideas on 22 ways of cutting power bills  and 38% off electricity and gas.  He said there is no economic reason for connection to the gas grid as gas has increased in price 75% over the last  5 years!  To make the production and usage of hot water  go further it is preferable to consider heat pumps and those with smart meters would find it simpler to trace one's usage regularly. It is possible to do this on line for the clever ones (my expression!)

But first on the list is to install LED lights  and thereby  using less power without heating and these are of course now being offered free of  charge. Next it is also a good idea  to ring retailers  to request what discounts are available ot to  threaten to switch if dissatisfied!

But before getting too technical adequate insulation is important  particularly hot water pipes and pressure release valves and a commonsense approach e.g. checking for draughts from old fireplaces and vents and the installatiom of old fashioned drapes and pelmets

Michael raised the question of showerheads which Tim said need not be either giving a satisfying shower or be saving hot water but could be both and if not satisfied could be returned! And that green power is provided by most retailers not only Powershop.
