Comes winter and we all go looking for mechanic to mend the water heater that has been shut down since last summer. Water gets so cold that you can not even think of touching the cold water let alone having to bathe with it. In this MAG tech news article we are going to tell you about a latest development in the field of engineering. Scientists have reportedly innovated a method to boil water faster. How much faster one may ask. well. less than trillionth of a second. No, its not a joke. Read on to find out about this amazing way to heat water faster.

Abstract:

Scientists from Hamburg centre for free electron laser science have devised an innovated way of boiling water in less than a trillionth of a second. This theoretical concept which has not yet demonstrated in practice is believed to heat the water near 600 Celsius in just a trillionth of second that is much less than proverbial blink of an eye. This technique would be the fastest water heating technique on planet earth.

Water being the universal solvent and single most important medium in which most of the chemical and biological process takes place has opened researchers mind to perform new experiment with heated samples of chemical or biological relevance. “Water is not just a passive solvent, but plays an important role in the dynamics of biological and chemical processes by stabilizing certain chemical compounds and enabling specific reactions” as explained by DESY scientists Dr.Oriol Vendrell from the center for free electron laser science CFEL.

How the water boils?

A concentrated flash of tetrahertz radiation is the key to heat the water at super fast speed. It consists of the electromagnet waves having a frequency between infrared waves and radio waves. Tetra hertz flashes can be produced with devices called free electron laser that send accelerated electron on a well defined winding path. The electron particle emits an electromagnetic wave while passing through each turn adding up to an intense pulse like laser. The tetra hertz flash alters the strength of interaction (molecular force of interaction) between water molecules in a very short time which  immediately starts to vibrate violently .

The scientists have computed the interaction of tetra hertz flash with bulk water. At supercomputer center julich the simulation were performed and used a total of 200,000 hours of processor time by massively parallel computing. It is surprising as on single computing machine this would correspond to around 20 years of computation “We have calculated that it should be possible to heat up the liquid to about 600 degrees Celsius within just half a picoseconds, obtaining a transiently hot and structure less environment still at the density of the liquid, leaving all water molecules intact,” explains Vendrell

In one go with this method we can heat about one nanolitre (billionth of a litre) ,this sounds really small but is large enough for most of the experiments carried out by the scientists in small scale world. It is interesting to know that an ink jet printers fire droplets that are as small as a picolitre which is thousand times less than a nanolitre.  Here the idea is to heat-up the ‘solvent’ so that many molecules start the desired chemical process at the same time and then watch the reaction in successive steps.

The team of the researchers currently investigates how the concentrated pulse of tetrahertz radiation affects various types of molecules dissolved in water, from organic to biological systems. The reaction progress can be explored with ultra short X-ray flashes that will be produced by the 3.4km long X-ray free electron laser European XFEL (currently is being built between the DESY campus in Hamburg and the neighbouring town of Schenefeld)
