A Tortoise Approach for US Nuclear Research and Development

| July 30, 2018

In Aesop's fable, a swift hare races with a deliberate tortoise. In the end, the tortoise wins by taking a slow and steady approach. The authors argue that, given the economic constraints on US deployment of nuclear power, a "tortoise strategy" is more prudent for US government nuclear R&D efforts.

The Sobering Reasons Congress Must Step Up On Arms Control

| July 19, 2018

Congress is asserting itself by passing additional sanctions to hold Russia accountable for its meddling in U.S. elections. Now it needs to step up its work on arms control — not despite the current tensions with Russia, but because of them.

A Process for Capturing CO2 from the Atmosphere

    Authors:
  • Geoffrey Holmes
  • David St. Angelo
  • Kenton Heidel
| 2018

The authors describe a process for capturing CO2 from the atmosphere in an industrial plant. The design captures ∼1 Mt-CO2/year in a continuous process using an aqueous KOH sorbent coupled to a calcium caustic recovery loop. They describe the design rationale, summarize performance of the major unit operations, and provide a capital cost breakdown developed with an independent consulting engineering firm. They report results from a pilot plant that provides data on performance of the major unit operations.

Trump and Putin Face an Urgent Arms Control Deadline in Helsinki

| July 12, 2018

As US-Russian relations continue to deteriorate, Presidents Trump and Putin appear eager to find common ground on arms control when they meet in Helsinki on Monday. The reason for their urgency is clear: The framework that has stabilized the US-Russian strategic balance since the fall of the Soviet Union is in danger of collapsing.

The Trump-Putin Summit’s Potential Nuclear Fallout

| July 10, 2018

The July 16 summit in Helsinki between Presidents Donald Trump and Vladimir Putin presents a unique opportunity to reverse the dangerous nuclear competition between the United States and Russia and should be welcomed, despite its inherent risks. The opportunity to stabilize U.S.-Russian nuclear relations by extending New START, a key nuclear treaty that is set to expire in 2021, is paramount and worth the issues that come with any meeting between Trump and Putin.
