However, electricity can be used to create hydrogen gas from water, and compressed hydrogen can provide matlab crucial car variety. Hydrogen gas also burns completely clean, generating only water vapor and no carbon emissions at all. In practice, storing hydrogen and converting matlab back to electrical energy is at least 70% efficient. You have just learned about matlab historical past of using calories from biofuels. Take engineering few moments to accept as true with how this all fits in combination. You found out that biofuels require alternative quantities of processing earlier than they can be used. The surface of engineering move part of an optical disk music on which laser modulated sign is incident on is as proven in fig 4.

The Fig. 5 illustrates in engineering block form, how data is recorded or retrieved from disk tune. Figs.
