1. Fundamentals of Nanoscale and Emergent Effects and Engineered Devices - IE Cold Fusion Investigation
FY2011 $16.745 million
FY2012 $11.65 million
FY2013 $5.5 million
This is the project where DARPA is spending about $34 million to investigate cold fusion on the nanoscale. They have found and generated excess heat for at least 2.5 days.
Description: The Fundamentals of Nanoscale and Emergent Effects and Engineered Devices program seeks to understand and exploit physical phenomena for developing more efficient and powerful devices. This includes developing devices and structures to enable controllable photonic devices at multiple wavelengths, engineering palladium microstructures with large deuterium loadings to study absorption thermodynamics and effects, enabling real-time detection as well as analysis of signals and molecules and origin of emergent behavior in correlated electron devices, and developing stabilization and scale-up methods to fabricate high pressure crystal structures at low pressures. Arrays of engineered nanoscale devices will result in an order of magnitude (10 to 100 times) reduction in the time required for analysis and identification of known and unknown (engineered) molecules. This program will develop novel nanomaterials for exquisitely precise purification of materials, enabling such diverse applications as oxygen generation and desalination, ultra-high sensitivity magnetic sensors, and correlated electron effects such as superconductivity. This program will compare the phenomenology of various biological, physical and social systems and abstract the common features that are responsible for their properties of self-organization, emergent behavior, and physical intelligence.
This looks like they are trying to investigate the science of cold fusion / low energy nuclear reactions

FY2012 $9.563 million
FY2013 $2.0 million
Description: This thrust examines the fundamental physics of materials at the atomic scale in order to develop new devices and capabilities. A major emphasis of this thrust is to provide the theoretical and experimental underpinnings of a new class of semiconductor electronics based on spin degree of freedom of the electron, in addition to (or in place of) the charge. A new all optical switch capability will also be investigated. It includes a new, non-invasive method to directly hyperpolarize biological tissues, leading to novel quantitative neurodiagnostics. New materials and prototype devices will be developed to demonstrate a new class of optoelectronics that operate with ultra-low energy dissipation (~100 atom-Joules (aJ)/operation).

- Demonstrated and independently verified visible light with Orbital Angular Momentum (OAM) induces 1.5 percent nuclear polarization equivalent -- to a 2000 tesla magnet.
