John Harrison's Idea For a Better World

There is no doubt that the gap is widening between those who have knowledge and those who do not and that knowledge is driving standard of living - I am convinced this is an underlying cause of many of the problems we have today such as the growth of medievalism and fundamentalism.

We need a global patent system that countries would agree to join. Patents should be really cheap to obtain  provided the inventors and corporations lodging them agreed to share their knowledge with those in need of it for a license fee commensurate with development costs and the needs of those who would benefit.

Perhaps millions would then not have to die from AIDS in Africa, perhaps Eco-Cements would be cheaper to disseminate, children would not die of malnutrition - perhaps we could save the world.

I am wrestling with ideas about this - any input in the new year from readers would be appreciated. Our patents have cost in the order of $ 175K in the last two or three years. They should have been cheaper as it is our intention to benefit the planet and in so doing benefit our shareholders. If we would have been prepared to minimise royalties in advance then perhaps many others would have as well.

If you think this is important - pass this newsletter on!

Annual Report For The Year Ended 30th June 2002

The past year has been most exciting and yet totally frustrating. Exciting because we have received some good publicity, had some good results, initiated some new directions and have come to realise the absolutely enormous potential of our cement and calcining/grinding technologies. Frustrating because we are “still in the box” and have, as yet, no income.


Highlights in chronological order include:

Activities and events that do not have a specific date:

Cement Making Capability

The company have a patent pending on a method of making reactive magnesia that is used in TecEco cements. John White from Delta Engineering will be making the first prototype of this equipment in exchange for shares and the design is well progressed. With the equipment it should be possible to make reactive magnesia with a specific surface area in excess of 100 m2 g-1 which is much more reactive than magnesia we are currently using at around 55+ m2 g-1

We have had many enquiries for the cement and believe it important to sell our franchisees the new plant we are developing to make sure the magnesia they use is highly reactive and the risk of dimensional distress, particularly if used in concretes generally, is minimal.

Block Making Capacity

It is essential the company get a block making machine to speed up testing and adoption of the block making technology and we have sourced several from Asia at a very reasonable price. There is also a possibility that we can lease one.

We hope get a machine in place and working in the next few months but need to raise some capital first.

Windsor Court Development - Hobart.

We are still in the race for the block work at Windsor Court but have to crank up the testing program.

Establishment of Office

Work is well progressed toward converting 240 Blacksnake Lane Granton, the site of an old concrete factory previously approved by the council, to use as a research establishment. Work will commence in fitting out the laboratories shortly.


There is a strong possibility that the company have picked up some consulting work to pioneer a new product in the cement industry that will help us pay our way.

Noting the Passing of a Friend and Shareholder

I received notification that Dr Bob Johannes had died on the 4th September 2002. Bob was one of the first shareholders of the company other than my family and Dr Vin Lyne and a person of tremendous intellect, knowledge, ability and understanding. Bob purchased shares when the future was by no means as assured as it is now at a time when our need was great and for that I will always be in his debt.


There are now some eight students doing reports on our technology around the world. Through Professor Abhi Ray at the University of Technology Sydney we hope to initiate student research that will hopefully grow into a major funding area early next year.

There are also a large number of other academics who are following our work around the world. We thank them for their support and in particular to Prof Fred Glasser, Prof Julia Stegman, Dr Leon Burgess-Dean and Dr Keith Quillin and Dr Phillp Nixon of the BRE in the UK.


We have taken on the biggest single market in the world and are not going to do it on a shoestring. We have made a commitment to maintain the share price at 10c until Christmas but after that is will have to rise reflecting our progress during the year and to maintain the expectations of existing shareholders.

The Future

We still have a long way to go and there is many a slip twixt cup and lip. So far however we are breaking all records for the rate of development for our new cement. Remember it took some 70 years for the development of Portland cement from the time John Smeaton built the Eddystone lighthouseto Joseph Aspidin’s patent and geopolymers have still not achieved commercial acceptance and have been under development since the fifties.

Next year I am determined to do my best to achieve:

Thanks for Your Support

Thank you to all our friends out there without whom this project would not be proceeding. There is a long list and I apologize for not mentioning everybody as there just would not be room in this report. I really appreciate your encouraging words and emails – they keep me going!

Thanks especially to my family for their support, Dr. Vin Lyne for acting as a director, Bill Fawdry for persevering with the block testing, John White for his encouragement and work on the calcining/grinding plant, Dean Lisson for arranging a meeting with abalone divers and all the other shareholders for their encouragement and financial assistance.

Thanks to Bill Guthrie and Phil Macoun from Qmag for the samples and encouragement, Jason Nairn from QCL for the flyash, Damien Giuliano from Causmag for the magnesia and Trevor Baldock for the pozzolan. Ralph Bottrill and Les Hay from Mineral Resources Tasmania helped with the XRD and microscope work. Thanks also to Prof Barry O’Grady for the unofficial refresher course on thermodynamics and kinetics, Ken Mackenzie, Ken Farrell, Stuart Murrihy, Geoff Kelly and many others for their help, advice and assistance.

Roger Fullerton has been doing and excellent job of proof reading and I am slowly getting the hang of the new SI nomenclature and units systems!

To all those other people out there who care about sustainability and who are supporting us, enquiring about product etc. Thank you.

Logo Ideas Anybody?

I think I have been told once too often that we need a simpler more stylistic logo. If anybody has any ideas please email us as we wanted to keep the globe and the phoenix (One of my sisters calls this the crow!)

The best we can come up with at the moment is a globe with two banners around it – one saying “TecEco Pty. Ltd.” and the other “Sustainable Technologies”

Inspiration anyone?

Why TecEco Eco-Cements are So Sustainable

People interested in the TecEco project often ask why it is that TecEco Eco-Cements are so environmentally friendly.

Consider first what properties a material would possess to be environmentally friendly and sustainable:

Scientists refer to the energy that goes into making a material as the embodied energy. As the production of energy other than from sources such as solar is environmentally unfriendly, materials that have a lower embodied energy are more sustainable. Around 98% of the world’s energy is derived from fossil fuels that when burnt to produce energy releases vast amounts of CO2. Much less energy goes into making TecEco Cements.

Lifetime energies are the energies required to heat and cool buildings over time. Building materials that have thermal capacity save on lifetime energies and are also very environmentally friendly. TecEco cements, being mineral based have a high thermal capacity.

Industrial wastes are a major global problem, if materials can be made that utilise wastes such as fly and bottom ash then disposal sites in the environment are no longer required. TecEco cements use a lot of wastes.

If materials have closed loops and can substantially be recycled then their impact when they are no longer required is much less. If they can be made of materials more naturally assimilated back into the earth then nature can very quickly convert them back to it’s own uses. TecEco cements can be substantially recycled.

If materials can be made that last much longer, require replacing less often then they are said to be more durable. More durable materials are therefore more sustainable. TecEco cements are potentially much more durable.

TecEco eco – cements score almost perfectly on all of the above and are therefore very environmentally friendly and sustainable.

JJ’s Column

Merry Christmas Everybody!

We are planning to work on the content of the website whilst on holiday at Bruny Island during January.

The website backend is running efficiently and is ready. The new statistics application is ready.

This month I wrote a few cron jobs (by this I think our wiz kid means a scheduled task on a UNIX based operating system –ed.) to keep everything automatically
backed up at regular intervals.

If you are having trouble linking to Newsletter.23 try changing the link to .htm which as standard as it gets.  Microsoft seem to be trying hard to make their software not backwards compatible so you have to purchase the latest operating systems and software.  Dad made me change this because he has a fetish for standardisation and file names.

Merry Christmas everybody.
