Petrol does not have a high enough energy density. If you have enough of it on board to provide the energy needed to reach orbit, the vehicle will be too heavy to lift off.
The reason that the hardness increases as the cold working increases is because of defects. Before the reduction, or cold working, the lattice of the material has a virtually defect free, or dislocation free, pattern. The cold working increases the amount of dislocations, and because of this, the material becomes more resistant to additional deformations. This manifests itself, most noticeably, as resistance to plastic deformations. Microscopically, this explained by the two types of dislocation shifts. Dislocation boundaries can move within the plane of dislocation relatively easily; this is known as a glide. However, when a dislocation boundary is moved up or down, out of the plane of dislocation, it takes much more energy. When a material becomes saturated with dislocations, any new dislocation will inevitably have to shift some dislocation boundaries out of their plane. This is known as a climb. Since climbs require more energy, more force is needed to plastically deform the material, i.e. the material becomes harder. The more dislocations a material has, the more climbs are done to achieve this new dislocation, making it harder to plastically deform a material. So the more cold worked the material is, the more climbs are needed, meaning that more energy is needed to deform the material. I'm pretty sure this is right -SMG
Turbine spins due to mechanical and rotation energy being applied to them. In a wind turbine that energy comes from moving air. Hydroelectric and water mill turbines use the energy from flowing water. Fuel and natural gas can also drive the turbines that generate electricity or provide the thrust needed by aircraft to fly also.
