Greetings to all from Brian here in N. Florida. I've been building Brown's gas generators for some time now. I've been testing a unit I've built that is producing 240 liters an hour. I've searched trying to find out how many watts or BTU's are in one liter of the gas? I've read that Brown’s Gas power potential is much greater than 50,000 btu/lb. Can anyone tell me how many liters in a lb? The plans I built my electrolyzer around states that the unit that produces 2500 liters an hour would use 10kwh. It also stated their cost is 4 cents a kw ( Canada ). I wasn't able to build the larger unit due to the expense at this time. So, please reply if you can answer my questions. Brian
