A great amount of ethanol fuel is currently produced by starch fermentation. This starch comes from grains such as wheat and maize. Fermentation is produced by a yeast culture. The digestion of starch by yeasts is done in two stages: the starch is initially hydrolyzed in sugars by a chemical or enzymatic process then sugars … Read moreMore bioethanol with yeasts?
The meteorological conditions of formation of tornados are complex but there is a constant: lower part of atmosphere is particularly hot and humid some hours before the beginning of a tornado. The thermal contrast between low hot atmosphere and upper cold atmosphere is instable and the mixture of these layers starts abruptly. The tornados are … Read moreSolar chimneys against tornados
Is it possible to test the sonofusion with the deuterium-tritium reaction? The research on sonofusion tries to obtain nuclear fusion in deuterated liquids. In a typical experiment of sonofusion, a beam of neutrons generates tiny bubbles in the liquid. An ultrasound field expands and contracts these bubbles. The nuclear fusion could occur when the collapse … Read moreSonofusion with tritium
