Service. Coming up next, the original series first ladies. Looking at the shell obama. After that, the state dinner with the french president. After that, the cochairs on the election in administration. You come into this house and there is so much to do. So much coming at you that there is no time to think or reflect. Hi, everyone. We are here digging up soil because we are going to plant a garden. I will not be satisfied until every single veteran and Military Spouse who wants a job has one. At the end of the day, my most important title is still mominchief. In 2008, barack obama was elected as our 44th president and he and First Lady Michelle Obama went into the history books as the first africanamerican first couple. One year into a second obama term, the first lady continues her focus on childhood obesity, support for military families, and access to educatio ....
Off. And that will cost me money. I know that from a power plant scrubber. There it costs me money. So but the problem now is the same. I have some sorbent. My absorbent had to be a little bit more stronger and it turns the out that scales rhythmically in the dilution for every factor two in dilution i need to pay an extra amount of energy. If you work it out, we pay about 1 1 2 to 2 times depending on how i do the accounting in energy than the flue gas scrubber must pay in the ideal solution. We cost a little more but not 100 times. We are a little more expensive by not linearly more expensive. Here you can see the energies. So this is how much energy we need for air, this is how much we would need for co2 from a power plant and what you see here, if the eveningeers can see this, this is rp log t. Let me put this out with a fancy formula so you know zca we act do math on occasion. What thisn basically says, the dynamics works. And by now nobody disagrees with this any more. The ther ....
Think just talking about air capture doesnt really explain why one would want to do it and how it fits into the bigger picture. To begin with, i think im talking here to the converted. I would like to point out that we really do need energy and we cannot solve our climate issues and other pollution issues which come from having energy by not having energy. We do need it for a variety of reasons. I would say we have planned it if we need food, we need fertilize for that, we need energy. We couldnt sustain the population we have without the process which affects nitrogen. If you want water there are unlimited supplies in the ocean if we could figure out how to desalinate and that takes energy and if you extract minerals from the ground, you again need energy. You came today mine coupled with a fraction of a unit because you have the energy to do so. In 1980 they were running out but they have 20 cup. So we can do better by throwing more energy at the problem pb. If you want to clean up a ....
