Apparatus for generation and use of lift gas
A balloon launch unit produces lift gas to enable balloon launch or to allow the prolongation of balloon flight. A method of using the balloon launch unit includes reforming a fuel source by reaction with water to generate hydrogen-rich lift gas mixtures, and injecting the lift gas into a balloon. The reforming operation includes causing the combustion of a combustible material with ambient oxygen for the release of energy; and heating a reforming combination of reaction fuel and water with the energy released from the combustion of the combustible material, to a temperature above that required for the reforming reaction wherein the fuel and water sources are reformed into lift gas. The amount of the combustible material combusted is sufficient to result in the release of enough energy to heat an amount of the reforming reaction fuel and water sources to the temperature above that required for the reforming reaction.
1. A system comprising:
a balloon or other flexible container for constraining a lift gas consisting essentially of hydrogen and carbon dioxide; and
an apparatus that generates the lift gas by reforming a fuel source in a reaction with water either on the ground or on-board the balloon, the apparatus releasing the lift gas into the flexible container;
wherein the fuel source is selected from the group consisting of alcohols, olefins, paraffins, ethers, aromatic hydrocarbons, propane, diesel fuels, gasoline, unrefined commercial fuels, crude oil, and natural gas; and
wherein the lift gas is captured in the flexible container for either launch from the ground or during flights so as to facilitate the extending flight duration of the balloon or other flexible container.
2. The system of claim 1 wherein the reforming of a fuel source is driven by energy released from a combustion reaction within the apparatus, the combustion reaction resulting from combustion of a combustible material with ambient oxygen.
3. The system of claim 2 wherein the fuel source and combustible material are the same.
4. The system of claim 3 wherein the fuel source and combustible material are an alcohol, ether, olefin, paraffin, or aromatic hydrocarbon.
5. A balloon launch unit comprising:
an apparatus that generates a lift gas consisting essentially of hydrogen and carbon dioxide by reforming a fuel source in a reaction with water,
wherein the fuel source is selected from the group consisting of alcohols, olefins, paraffins, ethers, aromatic hydrocarbons, propane, diesel fuels, gasoline, unrefined commercial fuels, crude oil, and natural gas; and
wherein the lift gas is released into a balloon to provide buoyancy to the balloon and allow for the launch of the balloon.
6. The balloon launch unit of claim 5 wherein the balloon launch is located at a remote site.
7. The balloon launch unit of claim 5 wherein the balloon launch is portable and can be transported on a vehicle, helicopter, ship or airplane.
8. The system of claim 1 , wherein the apparatus generates ballast for altitude control of the balloon or other flexible container.
