Lets Cook Limestone to Raise Atmospheric CO2 to

9/7/2016If the limestone is higher than the lava lake we can use gravity, a bit of C4 and a simple rail system to feed it. Some of the Rift Valley is below sea level. Then if we have to get it back up to sea level we could use one of these new Hyperloop things powered by the CO2 to get the concrete back up to the coast before releasing the CO2 to the atmosphere.
