Alan's website seems to have mistakes - http://lenr.qumbu.com/fake_rossi_ecat_v2.php
http://en.wikipedia.org/wiki/Energy_density Alan does calculations assuming that Rossi's 1 liter reactor (as described by professor Levi) was filled with some type of chemical that could heat the water. Supposedly the February test ran 16 kW on average for 18 hours. (16,000 W) x (18 hour) x (3600 sec/hour) x (1 J/sec per Watt) x (1 MJ/1000000 W) = 1037 MJ emitted by 1 liter. This means there needs to be a chemical that has an energy density of 1037 MJ/liter Diesel equals 32 MJ/liter For example at the end of his website Alan incorrectly writes that 1 liter of diesel would run 7.25 hours if it were producing 16 kW and using external air. The correct number is that 1 liter of diesel could run only 0.55 hours at 16 kW. This is 17.45 hours short of the actual run of 18 hours. So diesel has an energy density (MJ/liter) that is off by a factor of 33 (because 18 hours divided by 0.55 hours equals 33). In other words, burning diesel would not explain Rossi's test. Beryllium at 125 MJ/l would last 2.2 hours so it is too low by a factor of 8 (because 18 hours divided by 2.2 hours equals 8.6) Aluminum at 83.8 MJ/l would last 1.45 hours so it is too low by a factor of 12 (because 18 hours divided by 1.45 hours equals 12). But this is for solid aluminum and solid aluminum is almost 4 times more dense than powdered aluminum. So if Rossi had used 1 liter of powdered aluminum he would only get 0.38 hours (or 23 minutes) of 16 kW of heat output. It would be impossible to ignite solid aluminum - but I assume easy to ignite powdered aluminum. I assume powdered aluminum would make a lot of Al2O3 smoke - which is white (like steam). Did anyone smell the steam output? Did they smell steam or anything else? I assume the same would apply for extremely toxic Beryllium which would have to be in powdered form for it to ignite with air. The product is Beryllium Oxide which is not toxic in solid form from what I read. But I don't know if this produces Beryllium Oxide smoke which may or may not be toxic. 16 kW using the following would be: Boron at 138 MJ/l would last 2.4 hours (but would have to be in powdered form and this lessens the energy density) Graphite at 72.9 MJ/l would last 1.3 hours (about same as anthracite coal) Nitroglycerine at 65 MJ/l would last 1.1 hours TNT at 32 MJ/l would last .55 hours (33 minutes) Liquid H2 at 10.1 MJ/l would last .17 hours (10 minutes) Note that the different numbers for MJ/l for diesel, gasoline, H2 etc. used by wikipedia and Alan can be attributed to Higher Heating Value versus Lower Heating Value (I assume). Higher Heating Value assumes the products of combustion are cooled to 25 C (room temp) while the Lower Heating Value assumes the resulting water vapor is not condensed (so I assume that means the gasses stay above 100 C - but I see references to 150 C also - and I assume that is to make sure nothing condenses) If Rossi's "reactor" were 2 liters rather than 1 liter then all the calculations of run time hours can be multiplied by two (such as diesel could run for 1.1 hours instead of .55 hours). But still, how do you burn diesel without a combustion chamber and various air and fluid pumps? this is from Alan's website: >If the ENTIRE *1 liter* volume is composed of the fake material : >Lithium ion battery : 0.81 hours >Diesel, external oxygen : 7.25 hours >Compressed Hydrogen, external oxygen : 0.81 hours >Beryllium, external oxygen : 28.1 hours >(I haven't set up the calculations for Beryllium with Compressed Oxygen).
