|TecEco Eco-Cement Technology Must be Good if People are Trying to Take Credit for It: Comments on the Announcement by Dr Cheeseman of Imperial College
In an article dated 1 May 2008 published by CNPlus, the on line newsletter of Construction news in the UK and that has also appeared in a feed to aggregateresearch.com and elsewhere, it was reported that a Dr Chris Cheeseman of Imperial College London claimed he had invented a new carbonating magnesium oxide cement. The offending articles are available at http://www.tececo.com/rdandd.thirdparty.php as links in the text on that page.
If Dr Cheeseman was correctly reported TecEco Pty. Ltd. (TecEco) utterly rejects the contents of the news story as being a total misrepresentation.
According to the report \"while carrying out research on one such compound the Imperial team stumbled upon the fact that the resulting cement also absorbed further CO2 from the atmosphere as it hardened.\" TecEco achieved the development of Eco-Cements (its name for the same cement) some years ago and have many exemplars around the world. There is even a building in the UK made with carbonating magnesium cements supplied by TecEco that \"hardened\" in the manner described. The offending articles are available at under Third Party RD & D on the TecEco web site as links in the text on that page.
It would seem from the report that the only thing the researchers at Imperial College have stumbled over is the truth. Eco-Cements are magnesium oxide hydraulic cement blends that in permeable substrates will harden by taking up CO2 and water from the air and John Harrison, the managing director of TecEco who invented them in 1999 lodged a PCT to cover them in 2001. These same cements are according to the report exactly what Dr Cheeseman is now claiming he has invented.
That John Harrison of TecEco invented these new carbonating magnesium cements has been widely reported by the media around the world, the first major story being by Fred Pierce who wrote \"Green Foundations\", published in New Scientist Magazine, vol. 175 issue 2351, p38 on the 13th July, 2002. Further media reports, documentaries and other media confirming Mr. Harrison\'s invention are available under Media on the TecEco web site. Mr Harrison has since prepared many papers and presentations given at many major conferences around the world recording the fact from the very first that in porous concretes cements containing magnesium oxide carbonate and these same cements are also documented in the Archives of the TecEco web site going back many years.
Dr Cheeseman telephoned Mr. Harrison on the 8th May 2008 and claimed that the report was incorrect and not his doing. This excuse was not confirmed by Mr. Alasdair Reisner the publisher of the original article. On the contrary, when contacted Mr. Reisner stated that Dr Cheeseman made it clear to him that his team had invented something new. Because of this and because the new Imperial College spin off company to develop the cements is called Novacem and Nova suggests \"new\" TecEco do not believe these later claims by Dr Cheeseman that he was not trying to claim credit for the invention of the cements invented by Mr. Harrison and that CNPlus had not reported him correctly.
As Dr Cheeseman has had little experience with TecEco cements and not collaborated with us and as our patents and formulation know how both have very wide relevance we do not believe anything new or that we have not anticipated has been invented by him or his team. As for some time authors from the BRE, Imperial College and Cambridge university have been doing their best to discredit Mr Harrison and the TecEco technology in the last few years we now believe the agenda all along was was first to discredit and then take control of this very important technology. This ugly scenario is further described on the TecEco web site. (See RD&D/ThirdPartyResearch)
TecEco surmise that Dr Cheeseman\'s misrepresenation appears to be a ploy to attract funding and we further therefore comment that systems that force academics to be fiercely competitive in a commercial world they have little understanding of is bringing out the worst in them and that if we are to solve the urgent problem of global warming a much more collaborative approach is required.
As the true inventor Mr Harrison is aggrieved by Dr Cheeseman reported claims, particularly so as he met Dr Cheeseman in 2003 and 2004 and described the TecEco innovation to him and at conferences he attended. Dr Cheeseman was further given samples of porous (and thus permeable) carbonating magnesium cements by Mr Harrison during this period. Indeed Dr Cheeseman, his students and and John Harrison our managing director have corresponded about the cements. Understandably John Harrison is now very angry that Dr Cheeseman is reported as claiming he has invented them.
TecEco demand an investigate and will be writing to the Department for Innovation, Universities and Skills Technology Strategy Board who are funding Dr Cheeseman and the Rector of Imperial College regarding Dr Cheesman\'s misrepresentation as our board take Dr Cheeseman\'s reported gross misrepresentation very seriously.
TecEco warn Dr Cheeseman and others that they cannot reinvent history and Mr Harrison reserves his options to take further action if necessary in relation to the reported misrepresentation. As of the 9th May 2008 TecEco are waiting on complete written retraction that has been promised and when this arrives it will be published by us.

|Porecocrete Wins the Prize for the Best Innovation at Infrastructure 07
|Porecocrete, our pervious concrete pavement that also sets by absorbing CO2, won the prize for the best innovation at the recent Infrastructure Australia 07 Exhibition held between the 6-8 September 2007 at the Melbourne Exhibition Centre, Melbourne, Australia (\"Jeff\'s Shed\") Infrastructure Australia 2007 is a highly specialised trade exhibition focusing on the products & services required for commercial, industrial and major projects. There is rising interest on pervious pavement in Australia. One problem with the rising interest has been that TecEco are being swamped with interest about the technology and the demand for pervious pavement using Porecocrete is expected to be huge. TecEco\'s Victorian representatives are Asset Rehabilitation and Sustainability Services (ARSS). The proprietors Andy Ward or Leigh Unsworth may be contacted on 95970611.

|John Harrison Wins Episode of ABC Inventors
John Harrison, the inventor of tec, eco and enviro-cements and managing director of TecEco Pty. Ltd. has just won the 9th February episode of the New Inventors broadcast across Australia.
John won with TecEco eco-cement which is a blend of reactive magnesium oxide (reactive magnesia) with conventional hydraulic cements like Portland cement.
The invention is of global importance because eco-cements set by absorbing CO2 out of the air and combined with kiln technology also being developed by TecEco which captures CO2, could potentially turn the problem of global warming around.
