Solar Burner Tube!
Description
This Solar Burner Tube Will Collect Sun Light And Focus It In A Small Point At The Smaller End Of The Tube. You Will Have To Coat The Inner Surface With A Reflecting Material. For Me A Reflecting Tape Worked Well Enough To Melt Black Plastic. I Guess, The Solar Burner Tube (H40Fa18) Can Increase The Sun Light'S Energy Density By A Factor Of 45. ------------------------------------------------------------------------ Warning: Never Look Into The Focused Light Spot. Regular Sun Glasses Will Not Prevent Eye Damage. You Will Need A Professional Eye Protection. Store It In A Fire Prove Place Like A Metal Box. First Check Out "Maximum Permissible Exposure": Http://En.Wikipedia.Org/Wiki/Laser_Safety The Power Density Of The Sun On Earth Is About 0.1 W/Cm^2. A Maximum Of 0.001 W Is Defined To Be Save In Laser Class 2 (Pupil'S Surface = 0.39 Cm^2). You Should Never Look Directly Into The Sun. And You Should Never Look At A 45 Times Stronger Light Source, Too. Some Calculations For Version H40Fa18 : My Solar Burner Tube'S Effective Area Is A_Top - A_Bottom = 55.4 Cm^2 - 10.2 Cm^2 = 45.2 Cm^2. Let'S Say The Focus Area Size Is About 1 Cm^2. That'S Up To 4.52 W Focused In 1 Cm^2. Well, Tell Me If There Are Mistakes In The Calculations.
