Hydrogen replenished lighter-than-air vehicle and method to replenish hydrogen

Abstract

The present invention discloses a lighter-than-air vehicle and a method to replenish hydrogen into the vehicle while the vehicle is in the sky. The lighter-than-air vehicle can use helium or other gases that doesn't react with hydrogen as lifting gas. Hydrogen will be replenished into the lighter-than-air vehicle while it is still in mid-air. The lighter-than-air vehicles can comprise an aerostat, a hydrogen generator; a water tank and a duct. The present invention can also comprise an aerostat, a compartment, hydrogen generator, a water tank; and a duct. The present invention can also comprise an aerostat, a compartment, and a hydrogen storage alloy device. The present invention can also comprise an aerostat and a hydrogen storage alloy device.

         9 . A lighter-than-air vehicle comprising:
 an aerostat;   a compartment; and   at least one hydrogen storage alloy device;   wherein the said aerostat further comprises a pressurized chamber filled with helium;   wherein the said hydrogen storage alloy device is attached to the aerostat;   wherein the said compartment is air-tight ballonet located inside the pressurized chamber surrounded by said helium.   
     
     
         10 . The lighter than air vehicles of  claim 9  wherein said hydrogen storage alloy device further comprises a blower and control valve to release hydrogen from said hydrogen storage alloy and to replenish hydrogen to said compartment. 
     
     
         11 . A lighter-than-air vehicle comprising:
 an aerostat; and   at least one hydrogen storage alloy device;   wherein the said aerostat further comprises a pressurized chamber filled with helium;   wherein the said hydrogen storage alloy device is attached to the aerostat.   
     
     
         12 . The lighter than air vehicles of  claim 11  wherein said hydrogen storage alloy device further comprises a blower and control valve to release hydrogen from said hydrogen storage alloy and to replenish hydrogen to said compartment. 
     
     
         13 . A method of replenishing hydrogen to a lighter-than-air vehicle in the sky comprising:
 providing an aerostat comprising a pressurized chamber;   attaching at least one hydrogen generator to the aerostat;   providing at least one water tank to the aerostat; and   connecting the water tank to the hydrogen generator through at least one duct; and   filling the said aerostat with helium;   wherein the said hydrogen generator will generate hydrogen by using the water from the water tank;   wherein the hydrogen generated by the hydrogen generator will be blown into the aerostat.   
     
     
         14 . A method of replenishing hydrogen to a lighter-than-air vehicle in the sky comprising:
 providing an aerostat comprising a pressurized chamber;   attaching at least one hydrogen generator to the aerostat;   placing one compartment comprising an air-tight ballonet inside the said pressurized chamber;   providing at least one water tank to the aerostat; and   connecting the water tank to the hydrogen generator through at least one duct; and   filling the said aerostat with helium to surround the said compartment;   wherein the said hydrogen generator will generate hydrogen by using the water from the water tank;   wherein the hydrogen generated by the hydrogen generator will be blown into the said compartment.   
     
     
         15 . A method of replenishing hydrogen to a lighter-than-air vehicle in the sky comprising:
 providing an aerostat; and   attaching a hydrogen storage alloy device to the said aerostat;   wherein the said hydrogen storage alloy device will release hydrogen into the said aerostat.   
     
     
         16 . A method of replenishing hydrogen to a lighter-than-air vehicle in the sky comprising:
 providing an aerostat;   placing one compartment comprising an air-tight ballonet inside the said pressurized chamber; and   attaching a hydrogen storage alloy device to the said aerostat;   filling the said aerostat with helium to surround the said compartment;   wherein the said hydrogen storage alloy device will release hydrogen into the said compartment.
