Combustion

These burns were being carried out with the aim of reducing fuel loads, yet in many places I've seen the opposite.

Burning was stimulating dense recruitment of shrubs and other fire-responsive pioneer species, and changing the structure and condition of the vegetation.

In some places, within a few years of being burnt, the vegetation seemed denser and potentially more flammable than it had been before the fire.

In the years since, I've done quite a lot of work to try and document these patterns, and I won't go into all the work that I've done here, but if you're interested, I gave a talk to the Victorian Forest Alliance looking at some of these issues, and I'll provide a link to the presentation in the show notes.

Some reactions release energy, like if I lit my trebuchet on fire, which again, I will not do.

Why do I keep bringing that up? Burning is the rapid oxidation of chemical compounds, and as it results in a heat flow out of the system, we call that an exothermic reaction.

But other reactions suck energy out of the environment and into the system.

These endothermic reactions occur when heat flows into the system.

Puis là, on sait actuellement, selon la FIA, Red Bull ont le, le, le meilleur moteur.

Combustion.

Mercedes a le deuxième meilleur, donc les améliorations viennent en conséquence de quel pourcentage on est du premier.

Mais selon ses estimations, c'est quand même intéressant, là, le meilleur moteur, c'est Mercedes.
