Great, but...
Any effort to remove CO2 from the atmosphere needs to answer two questions:
1. How much does it cost?
2. How long does it keep the CO2 from the atmosphere?
Of course, there may be technological projects which have the potential to offer low cost carbon sequestration but are expensive in the beginning. Then the answer to the first question is the final cost.
At the moment the cap-and-trade cost of carbon emissions is around $20/tCO2eqv. All carbon capture and sequestration methods this far have been much more expensive.
(Re)forestation has its merits, but its long term carbon capture capacity is constant; certain area can only bind certain amount of carbon. And the very sad thing is that while tropical deforestation is the most significant land use related emission source, tropical reforestation is difficult. It is much more effective and less costly to stop the deforestation.
So, a good idea, but I am slightly sceptic about its efficiency.
