As technology has advanced, fuel usage has migrated to liquids and gases such as: oil, petroleum, alcohol, propane and natural gas. My focus will be on alcohol because of its simplicity and elegance.

  3. Clean Safe Sterile Simple Easy to find Easy to control Properties of alcohol

  4. Combustion of alcohol • CnH2n+1OH + O2→CO2 + H2O • CnH2n+1OH(the generic formula for alcohol) • Ethanol: CH3CH2OH or C2H5OH • Methanol: CH3OH • Isopropyl: CH3CH2OHCH3 or C3H7OH

  5. Denatured 100% alcohol, ethanol denatured with methyl Isopropyl Usually a mixture with water. 70%-90% Anti-freeze HEET Either pure isopropyl or methyl Different types of alcohol

  6. Open Vent Chimney Pressurized Each design has there own benefits and tradeoffs. Some are be easier to construct, while others are complicated but efficient. Different types of stoves

  7. Open vent • Extremely simple to build • Can use about anything • Not very efficient compared to other designs • Can use a wick

  8. Chimney • Very efficient • Fairly simple to build • Forgiving • Burns hot and clean • Can be modified or choked down to simmer

  9. Pressurized • Usually made from pop cans • Very light weight • Difficult to construct well • Delicate • Finicky • Require great skill and patience

  10. Building a cat stove • Gather and clean the materials • Cut center hole • Make church key holes • Punch inner wall holes • Insert insulation and screen • Push together and light

  11. Commercial designs • Varga Triad • Titanium alcohol • $30 • JetBoil • Liquid gas • $70 • Primus multifuel • Whatever is available • $100

  12. Pot Stand Wind Screen Pot Priming pan Matches Lighter Grabbing tool Alcohol Emergency supply of alcohol Measuring device Burn time chart Snuffer Multi-tool What you Need

  13. Strong Stable Can be integrated into the wind screen Made for specific job: Single pan Adjustable size Pot Stand

  14. Helps block wind from disturbing flame Concentrates heat Concentrates flame Can be used as base for pot stand Wind screen

  15. Cooking Pot • Choosing a pot is more about compromisesthan finding the perfect one. • Titanium • Steel • Aluminum • Size • Shape • Cost

  16. Used to jump start pressurized stoves Can double as a open vent stove Priming pan

  17. Banana’s Foster • 3-5 Bananas 1 stick butter 1 cup Light Brown sugar • ½ tsp cinnamon ½ cup banana liqueur 1 tsp. Vanilla • ½-3/4 cup Dark Rum • Slice bananas into desired size. Melt butter in skillet, add brown sugar and cinnamon, and cook over low heat, stirring until thick paste. Add vanilla and Liqueur and stir well. Cook ~3 mins. Add banana and cook over low heat, basting well with the sugar mixture. Cook ~5 mins. • Heat rum in metal cup over very low heat. Pour into mixture and ignite.
