Rail also compares favorably to other forms of energy storage. ARES systems do not respond quite as fast as batteries (five to 10 seconds, as opposed to effectively instant), but the company claims its capital costs are far lower. Also, rail cars and concrete slabs, unlike batteries, do not degrade over time.
Strain energy is given by U = Fδ /2, where, δ is compression and F is the force applied. Strain energy is given by U = ½ Vσε, where, V is volume, σ is stress, ε is strain. (σ ∝ ε) Strain energy is given by, U = σ 2 /2E × V, where, σ is stress, E is Young''s modulus, V is the volume of a body.
How It Works. ARES GravityLine''s TM fixed motor, chain-drive system draws electricity from renewables and/or the grid to drive mass cars uphill against the force of gravity – efficiently converting electrical energy into the potential mechanical energy of mass raised to a higher elevation. When the grid requires power, this process is reversed and the mass cars proceed
In effect, the trains convert the excess electricity to potential energy. When the grid needs that energy, the same rail cars carry the giant slabs downhill, converting the potential energy back into electricity. (Thanks, gravity!) The conversions are done by an electric motor. When it goes uphill, it consumes electricity.
