The second extraordinary strand is the extent of interdisciplinary experts. you have experts that are space scientists and physicists looking at the satellite data and the transmissions between the satellite and plane. my colleagues and i wrote a story that explain in arcane way they looked at the temperature of the satellite and the temperature of the satellite communication systems on the aircraft and they were able to use these temperature variations to determine slight fluctuations in the frequency of the communications in the radio waves. this is one more element to try to get closer to w...

They are designed to activate when there is a g-force. these elts are activated with a g-force. so if you -- let's say you ditched in the water just like the u.s. air flight did in the hudson, you're not going to have enough g-forces to activate the elts. if you hit the water really hard and the airplane sinks right away, then by the time those radio transmitters get underneath the water, the radio waves are not going to be able to propucgate. >> it subject sound like it's that big of a development then. thank you so much. the search continues underwater for the missing jet. that doesn't mea...

Gps, we can't use radio waves, we have to bring our own light, our own power. and there are no maps. i'm looking forward to the maps that "echo" will produce. i'm sure they will be fabulous. i think that will give everyone a bit of a boost because that will show the underwater terrain in incredible detail and give us some sense of it's a workable place. so these are things, again, that oceanographers deal with, all of these things routinely. i'm not saying it's easy. it's not easy by any stretch of the imagination but it is nothing that we're unfamiliar with. >> all right. we're going to conti...

Signals only travel a couple of miles. how are they getting hits over what seems to be larger distances than that? >> this is a great question, because i felt the same way, erin. how is this possible this we've been told over and over again it can't happen. well, the understanding, as we're told, is like this. imagine that there are layers of water in here that are warmer than others. they're called thermal climes. if you have the warmer layers than others and create barriers in here, the idea we're told by the searchers, people who are involved is they think essentially the signal is bouncing...

Massive satellite building would occur in space with robots? >> that's right. so, the module that we built a prototype of is an example of the kind that you would use to construct the big satellite. the module itself takes the sunlight and converts it into radio waves with a layer on top a solar panel and then the conversion electronics and then the bottom is an antenna and beam them to the earth. >> how can space solar toer, how can that power produce more energy than ground-based collectors? >> well, for one thing, you don't have to worry about nighttime or cloudy dais. on the east coast, we...
