Human used to get power from gas expansion in heat engine. Extraction of mechanic work from gaseous expansion is always low efficient, because circa 70% energy is hidden in the exhausted vapor in the form of latent heat and rejected or dumped out of cycle because the slow condensation may choke mass conservative looping. As liquid is hard to be compressed, power transmission can be reasonably assumed lossless, so harvesting mechanic power from liquid flow is high efficient. But historically it is rarely considered for how to form a powerful liquid flow in a typical gas-liquid dual-phase co-existed thermodynamic system, such as the most used Rankine-cycle heat engine. A new method or say Wei heat engine is invented that is based on a new defined Wei second class thermodynamic cycle. Such a new method converts thermal energy into high speed liquid flow during non-equilibrium condensation, though not too much efficient, as well as it jailbreaks the efficient limit of ideal Carnot cycle in an alternative way because the rejected heat is automatically reused to heat base liquid so as to reduce the consumption of heat source.

Based on the said liquid power heat engine, a series of modalities are disclosed, featuring a kaleidoscope of free energy, non-Stirling style external combustion, existing powerplant improving modification, immersed intra-cavitation combustion even with a variety of co-existing ammonia synthesis, and flue gas process with capture of combustion water vapor and carbon dioxide and NOx and sulfur dioxide.

A system includes a compressor, a concentrated solar panel (CSP) array, a turbine, and a recuperator. The turbine has a turbine casing assembly including at least a first casing and a second casing at least partially disposed around the first casing. At least one of the first casing or the second casing is at least partially transparent to solar energy concentrated from the CSP array to isothermally heat a working fluid as the working fluid passes through the turbine.

Systems and methods are presented for enhancing energy production and storage by integrating solar energy with geothermal processes. In certain embodiments, a hybrid geothermal/solar system increases energy yield from a closed loop geothermal system, stores heat in a wellbore, enhances power generation from geothermal brine, and/or facilitates carbon dioxide sequestration or conversion to fuel, all preferably utilizing solar energy as a supplemental heat source.

A portable human performance, renewable clean energy generator and pollution control system, with devices and associated methods to create mechanisms, paralleling organic flower plants for users to quickly harness it to improve their human performance. Knowing what mechanisms in a system should not operate at what times is crucial to force multiplying limited resource inputs. A tipping points arbitrage predictive model method leverages all mechanisms' operations toward specific needs of users, bending supply to meet demand, reducing waste and increasing output, whether in energy or human performance. Especially for disasters, when electricity is less reliable and portable generators are often used yet emit dangerous levels of carbon emissions, and even at low levels reduce human performance. This invention harnesses primarily heat, not fossil fuels. Synergistically, chemicals used for human performance provide heat, helping reach advantageous renewable energy tipping points, while reducing risk of adversely exceeding human performance tipping points.

A portable system and method for renewable-energy generation and human-performance optimization are disclosed. The system converts exothermic or thermoelectric energy into electricity through adaptive energy-arbitrage control to maximize overall conversion efficiency, while conditioning air composition to support physiological/cognitive function. A predictive model executed on a smartphone or embedded processor identifies cognitive, motivational, and behavioral tipping points and regulates subsystem activation using a cognitive free-return-trajectory method to prevent or restore from degraded performance. Multiple systems may interconnect to exchange thermal or electrical energy, operate autonomously in confined environments, and provide effector feedback to sustain cooperative, safety-critical, or goal-directed behavior. The controller may adapt its computational behavior or resource utilization under power-limited or mission-critical conditions to sustain essential human and AI subsystem performance. The invention forms an adaptive human-performance generator for disaster-response, civil-defence, and daily productivity applications.
