That is a neat little recycle program described in “New test traces underground forest carbon.” As fast as the CO2 comes out of the ground, the tree grabs the carbon by photosynthesis and leaves two oxygen atoms in the atmosphere. A portion of the carbon is stored until the wood rots or burns. Some carbon […]

Moo juiced? I live in Northern California, where forest-biomass power plants are common (“Radiation Redux: Forest fires remobilize fallout from bomb tests,” SN: 7/15/06, p. 38). One power plant takes the ashes that result and places them where cows forage. I’m wondering to what level of concentration this process will accumulate the cesium in organic […]
