Abstract: Systems and methods are described for sequestering carbon stored in organic matter while minimizing the release of carbon dioxide (CO2) and methane (CH4) into the atmosphere, with the carbon (C) being stored as char or coal through the coalification process. Organic matter will be moved to submarine hydrothermal vent fields where the extreme heat in the water will drastically accelerate the degradation of the material and destroy microbes that normally consume the organic material and release the carbon as CO2 or CH4. The oxygen level in the heated water around the vents is extremely low. The water surrounding these vents can reach temperatures of 400° C. (750° F.). Exemplary implementations may include constructing hydrothermal borehole vents to harness the energy continuously released from the Earth's core in the form of volcanic heat.

Abstract: Disclosed are methods, compositions, and composition packages for spray-coating a membrane for waterproofing a concrete tunnel applications. After primer coating is applied onto a surface in the tunnel, the coating composition is sprayed to form a membrane, and then concrete is cast or sprayed against the membrane so that it can bond to the membrane. Coating compositions comprise two or more acrylate monomers, as well as initiator, accelerator, and optional additive. Preferably, the coating composition is established by using a two-part package, one part having initiator, the other part having accelerator, and each part containing the monomers and optional additives so that the two parts can be shipped to the application site and mixed in a 1:1 ratio during spraying. The waterproofing coating composition provides excellent bonding with concrete.
