In roads towards specification are being made in a number of places ;

Some specification resources ;

http://www.siamwaterflame.co.uk/ ; supply two sizes of Oxyhydrogen Gas welding equipment ( suitable for prototype construction ) . However , @ ~ £ 3,000 ea. this is currently beyond budget .

http://www.maplin.co.uk/ ; home electronics for ( full frequency / amplitude adjustable ) PWM cicuitry are under construction ( still subject to circuit break / short circuit testing and output performance mapping ) . Workshop space and an ( electronic) oscilloscope are also on the company wishlist .

Materials have also been gathered for home - made winding of a custom transformer / chokes and fuel cell electrodes .

http://www.globalspec.com/ ; General e-mail alerts are now coming through for many aspects of Gas / Liquid Flow Control , flash back arrestors , Pressure Valves , Pumps etc

David Curtis ( http://www.controlstream.co.uk ) , a personal friend , has expressed a willingness to supply ( ex-sample ) flow control equipment to the project .

http://www.maxoncorp.com/ ; were contacted ( on the advice of the Lawrence Berkeley National Laboratory , USA , who hold patent on Low Swirl Combustion Technology ) ; MAXON corps' R&D department have no current plans to build small scale nozzles . Although MAXON is sceptical that this technology can be used to burn ( fast burning ) hydrogen , Sales and Marketing ( Belgium ) expressed an interest in the project and themselves contacted the Carbon Trust ( please see MRPF above (( TO POST )) .. as Maxon do not produce a suitable nozzle ( under their patent licence agreement ) , this thread will now move back to the Berkeley Laboratory .
