Abstract

Abstract At least one device for generating power from sunlight, wind and/or water movement supplies power to a hydraulic pump which uses such power to pump hydraulic fluid to a tank which receives and stores the hydraulic fluid under a constant pressure. The hydraulic fluid stored within the tank is allowed to selectively pass to a hydraulic motor whereby the hydraulic motor is activated.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 284 words
Means for activating hydraulic motors, said means comprising: (a) at least one power generating means for generating power from sunlight, said power generating means including a solar heat absorbing means having a hollow interior, including a quantity of heat absorbing expandable gas within said hollow interior of said solar heat absorbing means, including reflector means for allowing sunlight to be directed against substantially all portions of said solar heat absorbing means, including coolant spray means for spraying a liquid coolant over said solar heat absorbing means when the temperature of said quantity of heat absorbing expandable gas within said hollow interior of said solar heat absorbing means is above a set amount, including support means for supporting said solar heat absorbing means and said reflector means, and including a thermostat device for sensing the temperature of said quantity of heat absorbing expandable gas within said hollow interior of said solar heat absorbing means and for controlling the flow of liquid coolant through said coolant spray means, said support means including a gimbal-like device for allowing said solar heat absorbing means and said reflector means to be positioned so as to receive the maximum effect of the sun's rays; (b) hydraulic pump means connected to said power generating means for using the power generated by said power generating means to pump hydraulic fluid; (c) tank means connected to said hydraulic pump means for receiving and storing the hydraulic fluid pumped by said hydraulic pump means, said tank means including means for maintaining the hydraulic fluid under a constant pressure; and (d) means for allowing the hydraulic fluid stored within said tank means to selectively pass to a hydraulic motor whereby the hydraulic motor is activated.
Claim 2
Dependent Claim 284 words
Means for activating hydraulic motors, said means comprising: (a) at least one power generating means for generating power from sunlight, said power generating means including a solar heat absorbing means having a hollow interior, including a quantity of heat absorbing expandable gas within said hollow interior of said solar heat absorbing means, including reflector means for allowing sunlight to be directed against substantially all portions of said solar heat absorbing means, including coolant spray means for spraying a liquid coolant over said solar heat absorbing means when the temperature of said quantity of heat absorbing expandable gas within said hollow interior of said solar heat absorbing means is above a set amount, including support means for supporting said solar heat absorbing means and said reflector means, and including a thermostat device for sensing the temperature of said quantity of heat absorbing expandable gas within said hollow interior of said solar heat absorbing means and for controlling the flow of liquid coolant through said coolant spray means, said support means including a gimbal-like device for allowing said solar heat absorbing means and said reflector means to be positioned so as to receive the maximum effect of the sun's rays; (b) hydraulic pump means connected to said power generating means for using the power generated by said power generating means to pump hydraulic fluid; (c) tank means connected to said hydraulic pump means for receiving and storing the hydraulic fluid pumped by said hydraulic pump means, said tank means including means for maintaining the hydraulic fluid under a constant pressure; and (d) means for allowing the hydraulic fluid stored within said tank means to selectively pass to a hydraulic motor whereby the hydraulic motor is activated.
Claim 3
Dependent Claim 501 words
Means for activating hydraulic motors, said means comprising: (a) at least one power generating means for generating power from sunlight, said power generating means including a solar heat absorbing means having a hollow interior, including a quantity of heat absorbing expandable gas within said hollow interior of said solar heat absorbing means, including reflector means for allowing sunlight to be directed against substantially all portions of said solar heat absorbing means, including coolant spray means for spraying a liquid coolant over said solar heat absorbing means when the temperature of said quantity of heat absorbing expandable gas within said hollow interior of said solar heat absorbing means is above a set amount, including support means for supporting said solar heat absorbing means and said reflector means, and including a thermostat device for sensing the temperature of said quantity of heat absorbing expandable gas within said hollow interior of said solar heat absorbing means and for controlling the flow of liquid coolant through said coolant spray means, said support means including a gimbal-like device for allowing said solar heat absorbing means and said reflector means to be positioned so as to receive the maximum effect of the sun's rays; (b) hydraulic pump means connected to said power generating means for generating power from sunlight for using the power generated by said power generating means for generating power from sunlight to pump hydraulic fluid; (c) at least one power generating means for generating power from wind; (d) hydraulic pump means connected to said power generating means for generating power from wind for using the power generated by said power generating means for generating power from wind to pump hydraulic fluid; (e) at least one power generating means for generating power from the movement of water; f. hydraulic pump means connected to said power generating means for generating power from the movement of water for using the power generated by said power generating means for generating power from the movement of water to pump hydraulic fluid; (g) tank means connected to each of said hydraulic pump means for receiving the hydraulic fluid pumped by each of said hydraulic pump means, said tank means including a hollow tank member for holding the hydraulic fluid and including means for maintaining the hydraulic fluid held within said tank member under a constant pressure, said means for maintaining the hydraulic fluid within said tank member under a constant pressure including a piston-like member slidably mounted within the interior of said tank member in a fluid-tight relationship with the interior walls of said tank member above the hydraulic fluid held within said tank member and including a weight member attached to said piston-like member for utilizing the force of gravity to maintain the hydraulic fluid held within said tank member under a constant pressure; and (h) means connected to said tank means for allowing the hydraulic fluid held within said tank member of said tank means to selectively pass to a hydraulic motor whereby the hydraulic motor is activated.
