lithium. now, it's lithium. lithium, 1, 2, 3, 4, 5, lithium 5 and 1, 2-- what's the atomic number, gang? - 3. - 3. and you keep going right up the periodic table and then you come way up to what is the heaviest element found in large proportions in nature and that happens to be uranium. and uranium has 92 protons and most uranium has 238 nucleons. if i asked you people hey, uranium, honey, 238 nucleons, how many of those nucleons are protons? and you gotta know. you would say... 92. what if i said how many nucleons in the nucleus? you would say? 238. now here's where you need your calculator. how many of those nucleons are neutrons? and you would say... of course, you'd have to subtract, okay? you take this number, take away this number, and you guys say about 146, huh? you'd have 146 neutrons in that nucleus. so we have all the atoms, all the atoms which differ from one another principally by the number of protons in the nucleus, because anything that has three protons will hold three electrons, no matter how m

. >> it is a lithium-ion battery similar to the one you can find in iphones or other electronical devices. it's rechargeable and it's geared towards children in developing countries that don't have access to power. so, they are able to play for a few minutes every day, go back home, plug an led lamp and be able to do their homework or other tasks around the house. >> so far, development of the soccket has been funded by donations. but victor angel and melissa seligmann hope that at some point it will become financially viable. the 25-year-old technician is planning to keep refining the design. the aim is to introduce it in places where there's no access to electricity. >> one of the biggest things was making it light enough for children to play. right now it is 50 grams heavier than a traditional soccer ball. it is completely airless so that it doesn't puncture. a lot of times when you donate a ball to the developing world it gets flat in a matter of weeks and ends up in the landfill. this one you can actually play around in the rain or in the mud. >> the main question is obviously does i

the new aluminum lithium which before we could only manufacture right here in pittsburgh were recreatedis is all happening. particularly also because there are some advanced industries here in the u.s., very good customer base. that's where we want to play and where we are playing. liz: you guys made it. 125 years. the top through the great depression, two world wars, all kinds of issues. can you make it through the taper? everyone is wondering how the eventual tapering of the bond buying program by the fed would affect business. how do you see it? >> i see it very simply. look, the low interest-rate environment has created some extraordinary impact. we have seen new types of investors coming on that impacted our market. at the same time, we will see, the moment the interest rates will go out the federal reserve board's all around the world will only allow that to happen when you feel that general economic activity going up. so demand will increase, interest rates will come up. this is basically leveling out. so we are not afraid of the tapering environment at all. in fact come i would

actually, in the dealers because lithium motors is one that we've been involved in., which has some exposure here in europe. they've been doing spectacular, much better. >> at this particular moment, do you keep running those? >> we've taken a little bit of profits, but we continue to think there's value there. we didn't build enough car necessary 2009, '10 and '11. not only getting back to a normal level, we have a lot of catch up. cars are older today in the united states than they've ever been. i believe the average car is around 111 1/2 years old. >> i know how you feel. >> come on, ross, don't sell yourself short. >> where would it be good to be right now with a lot of risk coming up? >> we look at company specific, bottoms up. we still love the television broadcasters. we think that the affiliate companies like -- yeah. like sinclair, nextstar, lynn, great television. those are very interesting ideas here because they're getting much more -- they're getting paid for their programming for the first time. espn and discovery has been getting paid a lot for their p
