Field testing of two prototype air-source integrated heat pumps for net zero energy home (nZEH) application

By integrating multiple functions into a single system it offers potential efficiency and cost reduction benefits. Oak Ridge National Laboratory (ORNL) and its partners have designed, developed, and tested two air-source heat pump designs that not only provide space heating and cooling, but also water heating, dehumidification, and ventilation functions. Some details on the design, simulated performance, prototype field test, measured performance, and lessons learned are provided.

Staged Z-pinch for the production of high-flux neutrons and net energy

A fusible target is embedded in a high Z liner, ohmically heated and then shock wave heated by implosion of an enveloping high Z liner. The target is adiabatically heated by compression, fusibly ignited and charged-particle heated as it is being ignited. A shock front forms as the liner implodes which shock front detaches from the more slowly moving liner, collides with the outer surface of the target, accelerates inward, rapidly heating the target, adiabatically compressing the target and liner and amplifying the current to converge the liner mass toward a central axis thereby compressing the target to a fusion condition when it begins to ignite and produce charged particles. The charged particles are trapped in a large magnetic field surrounding the target. The energy of the charged particles is deposited into the target to further heat the target to produce an energy gain.

Is net carbon negative crude achievable with CO2 enhanced oil recovery?

This presentation was given at the 2016 Carbon Capture, Utilization, and Storage Conference in June 2016, and provided the background on the complexity of determining the greenhouse gas emissions from this type of complex interconnected energy system. It also showed results across the wide range of possible permutations of this type of system.

Distributed Wind Deployment: Net-Zero Homeowner

This is a case study on distributed wind. The owner had a 25-kilowatt Eocycle wind turbine installed on a 140-foot tower, which separates the turbine from treetops and other potential barriers to consistent winds.
