Zout water lijkt - onder speciale condities - flink te kunnen branden. Hoe het komt is onduidelijk, maar het verschijnsel wijkt nogal af van wat we altijd hebben gedacht. Interessant filmpje op YouTube.

Het is een kulexperiment. Wat je ziet is een plasma dat geel is gekleurd vanwege de daarin aanwezig Na-atomen (denk aan snelwegverlichting). Water kan NIET branden, het IS al verbrand; en als je met dit apparaat, dat op miraculeuze wijze geen afscherming nodig heeft (denk aan je magnetron), water zou kunnen splitsen in waterstof en zuurstof, moet je precies evenveel energie in het water stoppen als je met 'verbranding' weer terugkrijgt.

Je bent wat vooringenomen met je oordeel. Door de heisa in de media is de interesse van een heleboel mensen gewekt en het biedt misschien een simpele mogelijkheid om waterstof te winnen. Al met al best een positief bericht.cymric schreef:Het is een kulexperiment.
Daniel Kammen directs the Renewable and Appropriate Energy Laboratory at the University of California at Berkeley. While he remains skeptical about the phenomenon as an energy source, he said, "it sure would be neat if true." He explained that hydrogen is the most common element on Earth and a great fuel if pure, but it is always locked with at least one other element—oxygen to form water or carbon to form methane, for example.
Today most hydrogen is extracted from fossil fuels like natural gas by burning them, which releases carbon dioxide, a greenhouse gas. Water can also be split into hydrogen using electricity, in a process known as hydrolysis. But this is inefficient and requires large amounts of power. So researchers would like to find ways to isolate hydrogen with minimal energy and no fossil fuels, Kammen said. The burning water technology could potentially open such a door, he added. Solar, wind, or wave energy, for example, could power the radio frequency generator, he said. As salt water passes through the generator, the hydrogen would be released.
"That would be a remarkable source of hydrogen and then you could either burn the hydrogen directly or use it in a fuel cell," he said.
Penn State's Rustum Roy points out that no one has yet looked into the energy balance of the process—how much energy is put in and how much is released. Nor, he added, are the environmental impacts of the process known. For now, the most immediate potential technology application is desalination—the process of removing salt from water—because the water formed after combustion is free of salt and other contaminants. "It's really a miraculous process: water-breakup-water," Roy said.
Further Research
Brent Haddad directs the Center for Integrated Water Research at the University of California, Santa Cruz. He commented in an email that the "research is located in the right place: at the nexus of energy production and water treatment. But it is too early to tell what the practical applications will be." Roy met Monday with officials from the U.S. departments of defense and energy to discuss the discovery and seek research funding. He said entrepreneurs from all over the world are also contacting him via email. "They are all saying, Holy cow, everything has changed."
