Hey, that's funny Lindsay. The National Hydrogen Association did take physics 101. It's why we know how to make small, efficient planes, vehicles that go over 300mph, fuel cells that can power a building, silently with no emissions and cars that travel over 400 miles on one tank and fill-up in 2-5 minutes. You don't have to slanderize and badmouth other technologies to promote your own. There's room for innovation from everyone. You can disagree all you want, but let's place nice, like gown-ups.
My reply to Patrick
Hey Patrick glad you read the piece. I have no technology that I own or promote. I just promote knowledge and help folks understand in a simplified way the laws of thermo dynamics.
OK so you guys powered a 35 pound drone with 4 pounds of hydrogen and kept it aloft for 23 hours with a 0.75 kw fuel cell. Please tell us how much the US Navy paid for this toy? A fuel cell vehicle like the Honda needs about 0.3 kwh per mile. This means we need 0.5 kwh of hydrogen as the FC is approx 60% efficient. The production of H2 from natural gas is approx 75% efficient so we need 0.67 kwh of natural gas for the vehicle to go a mile. A gallon of gasoline has 33.7 kwh so your Honda fuel cell vehicle gets 50 mpg equivalent. Same as the Prius on Gasoline. The prius is sold (not leased) for $22,000 and the Honda fuel cell vehicle costs Honda over $400,000 to produce.
Patrick you should get real and you should stop playing games nicely. I could have taken the 4 pounds of hyrogen that were burned in keeping the drone aloft and used them in a balloon to displace 28 pounds of air and therefore lifted 24 pounds of balloon plus load. Let's say the balloon weighs 4 pounds so I can lift 20 pounds of payload. The lighter than air blimp will need about 1/3 the fuel to go the same distance as the drone as I do not need thrust for lift and only need thrust for propulsion. Now that you have learned physics 001 please go to Congress for another $3 billion of my tax money so It can be wasted on repulsion instead of propulsion.
Patrick let's continue this debate as I note you are the Vice President, Technology and Communications of the National Hydrogen Association. Readers you can also go to the NHA site at http://www.hydrogenassociation.org/ Patrick after our debate we will poll the greenexplored readers to see if they have been given value for $3 billion of tax payer funding.
