It is not a great leap of the imagination to suggest that the present HotCat is not far away from what is needed for the first LENR airplane... can we call it the CatBird?
Little doubt it will be a drone, even if the EADS design was made for a human pilot (assuming that the deep pockets "funder" will be, who we think it will be). Imagine six HotCats, each requiring 300 watts input to produce 1800 watts output (6:1 COP as claimed). If the fractal-etched converter cells (antennae is more precise than photocell) are only 30% efficient, which is a fair estimate based on actual testing - then this is workable, but not optimized) as there is only a net electrical overage of 240 watts each or around 1440 watts for each 6-Cat array. Again, these fractal cells have been prototyped at exactly the expected temperature profile which is expected. Fortunately - this calculation overlooks the more likely situation where 6 HotCats can be arranged as a hexagonal core, with the planar fractal converter chips enclosing the core - so that each HotCat supplies most of the thermal input for the others by direct thermal coupling - and with the fractal photocells arranged in panels - outside of the central core to supply electrical current. Thus, with this slight revision, you have at least 200 watts of the required 300 which is needed supplied directly by thermal irradiation from adjoining cells, lessening the electrical input - so only 100 watts of electrical power is needed (for more precise control). This arrangement changes everything, since the net output of each cell is reduced by the 200 thermal watts captured by neighbors and only 1600 goes to irradiate the fractal antenna. The electrical output drops to 1600 x .3 or 480 per cell, minus the 100 needed as electrical feedback for precision thermal control. This is a total of 6 x 380 or 2880 watts net output ... instead of the original 1440 - essentially doubling the power that can be used to drive the propellers. If a single 6-Cat module of 2.88 kW is not enough, and it will probably not be enough to also power the spying gadgets, then many more modules can be added. For the weight of a pilot, this glider could have easily have 10 or 11 modules or 30 kW continuous. If that power can pull the Cat-Bird to the jet stream, The Pentagon could deploy hundreds of these CatBirds as surveillance drones all over the world, just like low-level satellites and in the end save millions ... ...and you thought the spying on citizens was already bad enough. You haven't seen anything yet. Given the present state of technology, and assuming that Rossi is not a fraud, and that the "funder" puts a few thousand engineers on this immediately - it could happen much sooner than expected. All of the parts are in place. L-M or Boeing are ready to move. It is just a matter of time. _____________________________________________ We have thrown out ideas for direct conversion before. At the high temperature of the HotCat, they become far more feasible. The most obvious one - if there is IR resonance as part of the operational parameters, is a photocell designed exactly for the emission spectrum. These have actually been fabricated http://cearl.ee.psu.edu/Projects/Assets/Project2/Project2_3_1/DualbandIRfilt ersDrupp0904.pdf Notice the wavelength captured is very specific to the geometry of the fractal which is etched. This favors high efficiency at say 20 terahertz - with efficiency possibly above the range of broad-band solar photocells. An optimist could imagine 6 HotCats in a hexagonal array, surrounded by these fractal antenna powering the EADS glider, manned (or more likely unmanned as a drone) for a very long time. "Around the World" in two weeks by 2015? In your dreams, maybe. Jones
