Synfuels are made from energy sources that are more plentiful than carbon oil sunlight water

The answer is: oil.

Synfuel (synthetic fuel) is a liquid fuel, rarely gaseous fuel, made from syngas.

Syngas is a mixture of carbon monoxide (CO) and hydrogen (H₂).

Syngas goes to additional conversion process to become liquid fuel.

Some methods for manufacturing synthetic fuels are methanol (CH₃OH) to gasoline conversion and direct coal liquefaction.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
