This flame is made of pure water

Scientists have invented a new low-cost method to create a safe welding flame using water as its only fuel. Called the Safeflame, the device splits water in oxygen and hydrogen, recombining them both outside of the torch’s mouth to create fire. And the only byproduct is water.

In the past, this method was too pricey for wide adoption. The success of the Safeflame is that they have managed to make it a lot cheaper and also safer than traditional propane and acetylene torches, according to Andrew Ellis, one of the Safeflame researchers:

We’ve got a whole team of chemists working on new formulations of membrane, which have shown increases in the performance of the electrolyzer. We’ve also been doing lots of research on catalysts, trying to reduce the amount of platinum and looking into much cheaper materials that can be used in the cells. And this research has led to big reduction in the cost of electrolyzer systems.

Talking to Euronews, Ellis said that the new system has been “developed to use a standard mains electricity supply, and water. The water is split into hydrogen and oxygen gases and fed into a torch where a flame is produced, which can then be used for brazing or any other industrial application where flame is used. So it’s just using water to make a flame, basically.”

What’s more, the torch itself remains cold to the touch at all times because, according to the Ellis, “the flame, as it’s being produced, burns on the outside of the torch. And when you turn the flame off at the [end] of operation, the torch will also remain cold afterwards, so you can put it down anywhere you want.” In the video you can see the guy touching the torch’s tip even while it is in operation.

About steventorresramos

I have over (24) years of Computer Aided Drafting & Design experience and over (16) years of IT experience. After graduating high school I attended a Technical College and earned an Associate Degree in Drafting & Design. I then enrolled at the University of Puerto Rico where I earned an A.S. in Civil Engineering Technologies. While attending the Univ. of Puerto Rico I worked as a freelance Drafter for a variety of architects and engineers. During my senior year I began to work for the firm Planning Management & Development in Ponce, Puerto Rico. Two years later I was offered the position at Mario Corsino & Associates, which later became InterGroup a medium size Civil Engineering, Architectural and Planning firm in Bayamon, Puerto Rico. At InterGroup I became assistant chief drafter where I was responsible for 20+ drafters & civil techs, and this is also where I began my IT training. In 2000 I decided to move to St. Petersburg, FL where I was hired as CAD Manager at Advanced Engineering & Design a small Civil Engineering firm established in 1998. Currently still employed by Advanced Engineering & Design I’m now the CAD/IT Manager. I have also continued to expand my knowledge base in both the IT & CADD fields through continued training, certifications, and attending Autodesk University. I’m currently an Autodesk Certified Professional proficient in AutoCAD, Civil 3D and various other Autodesk products. I have been the President of the Tampa Bay Autodesk Users Group (TBAUG) since late 2007 and a member of Autodesk Users Group International (AUGI) since 1996. I have an A.S. Degree in Computer Networking , a Bachelors of Applied Science in Technology Management and currently finishing work on my Masters in Computer Information Systems. I’m a licensed drafter in the US Commonwealth of Puerto Rico, and a Microsoft Certified Professional. I hold certificates as a Microsoft Certified IT Professional: Server Administrator, Cisco Networking Associate Professional and Linux Administrator.
