Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
95 words
An electrical energy system comprising: an electric utility having an electricity generating apparatus and distribution lines; a plurality of electric vehicles; each electric vehicle including a metal/air battery operated by a liquid-like slurry; means for removing spent slurry form said vehicle battery; means for re-charging said spent slurry received from said removing means externally said a vehicle; and electric power storage means receiving electrical power from the electric utility and being connected to said re-charging means so as to supply electrical power to the plurality of electric vehicles and to the electric utility when required.
Claim 2
Dependent Claim
95 words
An electrical energy system comprising: an electric utility having an electricity generating apparatus and distribution lines; a plurality of electric vehicles; each electric vehicle including a metal/air battery operated by a liquid-like slurry; means for removing spent slurry form said vehicle battery; means for re-charging said spent slurry received from said removing means externally said a vehicle; and electric power storage means receiving electrical power from the electric utility and being connected to said re-charging means so as to supply electrical power to the plurality of electric vehicles and to the electric utility when required.
Claim 3
Dependent Claim
41 words
