1. A method of recovering energy, the method comprising:
- transferring a first foam to a first cylinder assembly, the first foam having a first foam expansion ratio;
expanding the first foam in the first cylinder assembly, thereby recovering energy therefrom;
thereafter, transferring a second foam to a second cylinder assembly different from the first cylinder assembly, the second foam having a second foam expansion ratio larger than the first foam expansion ratio; and
expanding the second foam in the second cylinder assembly, thereby recovering energy therefrom.
