REALITY CHECK…

💡
THE PROBLEM IS HOW MUCH ENERGY WE HAVE TO PRODUCE HYDROGEN with our little pod (Of course this is just a prototype…)
  • After our experimentation, we produce about 350ml hydrogen in an hour
  • A six hour exposure to the sun (assuming full day) —> about 2L
  • We are running the fuel cell sub-optimally (at about 2W), but we have three panels, 10W each (⇒ 30W)
  • We can then estimate 30/2*2 = 30L in six hours.
  • This is in meters cube: 30/1000 = 0.03 cubic meters of hydrogen at atmospheric pressure
  • 1kg of liquid hydrogen corresponds to 11,2 cubic meters of its gas form
  • Meaning that the equivalent liquid hydrogen we produce in a “day” is equal to 0.03/11.2kg = 2.6 ml of liquid hydrogen
  • Also, 1L liquid hydrogen ←→ 0.27L gasoline, so 2.6ml H2 ←→ 0.0026*0.27 = 0.7 ml gasoline
  • Scooter: 60km/L —> … we can do 60km*0,0007 = 42 meters…
