Oamenii de ştiinţă din Brazilia au anunţat că au descoperit o nouă metodă de a îmbunătăţi producţia biocombustibililor. Cercetătorii spun că, dacă fermentarea trestiei de zahăr se face în prezenţa unor magneţi, producţia creşte cu 17% şi procesul este mai eficient. O relatare de Matt McGrath:

Ascultaţi povestea

Many countries around the world are trying to reduce their dependence on oil by emulating Brazil where bio ethanol provides about 30% of automobile fuel. But the process of making bio ethanol by fermenting sugar cane is time-consuming, inefficient and expensive.

Now a team of researchers at Brazil's State University of Campinas say they have found a way of improving the production process by using extremely low frequency magnetic waves. The team attached two electromagnetic generators to a vat containing a mixture of yeast and sugar cane. They found that the production of ethanol increased by 17% and it speeded up the time required to produce the fuel by two hours.

The scientists involved are unsure as to how exactly the process works but they believe that the magnets stimulate the yeast and make it work faster and more intensely. They believe their discovery can be easily implemented at an industrial scale.
