HERE & NOW Technical Info

A rotary-electric hybrid platform designed to convert traditional engine losses into usable power.

​

System Overview
Integrated Rotary-Electric Power Unit

The HERE platform is a rotary engine that behaves like a four-stroke system while acting as a multi-point electric generator. Instead of driving separate alternators, pumps, and balance shafts, HERE integrates electrical generation and energy management directly into the rotating assembly.

​​

Key goals:

• Transform parasitic mechanical loads into energy

• Expand the efficiency plateau over a wide operating range

• Enable simple, modular hybridization

​

HERE: The Primary Generator

The HERE module in its reference configuration:

• Displacement: ~800 cc

• Type: Hybrid Electric-Rotary Engine (4-stroke-equivalent behavior)

• Primary role: Continuous electrical power generation

• Target operating: ~3,600 rpm generator speed (for 60 Hz systems)

• Key features:

  • Dual integrated starter-generators (ISGs) on the shaft

  • Internal flow designed for low pumping loss

  • Magnetic and hydraulic strategies to reduce bearing friction

  • Interfaces for forced-induction and thermal management modules

​

Design envelope (not yet test data):

• NA configuration: ~11–14 kW continuous electric output

• Mildly boosted: ~16–20 kW

• Full system with energy recovery: ~20–27 kW

​

NOW: Stabilized Boost and Dynamic Torque

NOW is a companion device designed to:

• Provide instant torque and assist in transient load response

• Act as an electrically assisted supercharger / pre-charger

• Optionally incorporate micro-combustion for additional energy input

• Operate in fuelless modes for pure electromagnetic assistance

• Help stabilize pressure and balance loads across the system

 

NOW’s geometry and control strategy are engineered to pair naturally with HERE, offering improved boosting and smoother operation without relying on belts or fixed-geometry compressors.

​

From Losses to Recovery Points

Traditional engines lose energy through:

• Friction and bearing drag

• Pumping losses

• Accessory belts and gears

• Counterbalance shafts

• Exhaust energy

• Throttle and part-load operation

​

The HERE & NOW system introduces engineered recovery points:

• ISGs: electrical generation from shaft motion

• Magnetic/hydraulic balancing: reduced friction and wasted vibration

• Controlled pressure paths: via internal valving and flow management

• Thermal Management Module (TMM): unified cooling of oil and coolant circuits

• Exhaust-based regenerators: e-turbo and related systems

​

Operating Pressure (BMEP-Equivalent Targets)

At ~3,600 rpm and 800 cc displacement aingle rotor, continuous operation bands are designed as:

​

• HERE (NA): ~6–8 bar equivalent BMEP

​

• HERE + NOW: ~8–11 bar

​

• HERE + NOW + FI (forced induction / recovery): ~10–13+ bar

​

These ranges are chosen to:

• Stay within a conservative, durable zone

• Align with modern boosted engine practices

• Prioritize broad efficiency and subsystem integration over peak hp/cc

​

All values are pre-prototype design targets and will be refined with dyno and endurance testing.

​

Scaling the Architecture

The same architectural principles can be extended by:

• Stacking multiple HERE rotors (multi-rotor configurations)

• Using multiple NOW modules for larger systems

• Adapting the design to different fuels and duty cycles

• Integrating with 48 V or 800 V electrical architectures

 

Target applications:

• Hybrid marine propulsion

• Mobile generator sets

• Powersports

• Compact automotive range extenders

• Auxiliary power units for aerospace and defense

• Automotive propulsion
