Relative to the energy obtained
from the burning of fossil fuels, non-combustion renewable energy is generally
less reliably available exactly when needed.
Because of the intermittent or seasonal nature of most forms of renewable
energy, efficient energy storage is essential.
Line 1:
Phase change dynamics is the study of
heat storage in phase change materials, which absorb or release large
amounts of latent heat (heat of vaporization,
melting etc) when they go through a change in their physical state, i.e. from
solid to liquid and vice versa..
Line 2:
The light in a fiber-optic cable travels through the core with total internal
reflection. Because the cladding does not absorb any light, the light wave can
travel great distances.
Line 3:
Combine these concepts for a synergistic total.
