A really bad idea

I’ve just come across a pretty bad idea on a site which claims to be about popular science… popular hogwash if the rest of it is up to this standard.

As reported idea revolves around converting carbon dioxide from smokestacks to baking powder. Baking powder works by releasing carbon dioxide in the oven when it gets hot. That’s why cakes rise.

Who’s for perpetual motion then?

    It reverts back to CO2 and its other parts when heated over 50 degrees celcius. It also reverts back when exposed to an acid. However, the storage of CO2 in a solid is much better than having it free in the atmosphere. How can you call this a bad idea? 50 degrees celcius is fairly hot, and I don’t think that the idea is to put the baking soda in an oven after it is used to sequester the excess CO2 given off from factories. It could be stored in salt domes, or anywhere else that is kept dry and cool. It is also reported to be food grade, so it can be used for other purposes.
    I don’t think that people making cakes or baking bread will make the process futile. These are the kind of ideas that need to be used, or at least tried. All of your talk about oilgae and ethanol and corn production and you think that THIS is a bad idea? I don’t get it.

    Hi Diamond,,
    Its the final use that looks daft, if the sodium (hydrogen?)carbonate is going to is going to be buried in salt domes then that’s fine and dandy. I got rather focused on the idea that it might be used as baking powder, and that seemed silly. Thanks for the comment
