asteroza + wankel   22

GERA Technical Papers |
Nuclear piston engine, using gaseous "fuel" and hydrogen gas moderator, with neutron reflector piston and cylinder. Uses piston top-dead-center compression effects and a "spark" (external neutron source, like an ADSR particle accelerator neutron spallation target, or some sort of cylinder wall embedded neutron source). Wonder if LiquidPiston reverse wankel would also work well here. Negative void coefficient is nice too.

Clarion Labs rotary piston generator
See US patent application 20110133486 for the integrated generator in the wankel rotor. They claim to use the integrated generator to fiddle with piston rotation timing to improve efficiency (loiter at top dead center?), no permanent magnets due to an inductive layout,and ceramic apex seals.

Clarian Labs - Making Ideas Possible
These guys were allegedly working on a compact single rotor wankel generator to be used in a hybrid battery pack. I wonder if this could be used in the Logos Technologies stealth bike SilentHawk?

Appears to be a single rotor wankel generator on it's side, so it is a low flat pack. AVL was doing something similar previously. I wonder how they handle the vibration of a single rotor?

太陽光の熱を朝日から夕陽まで回収し効率よく発電:報道発表資料|2013年 プレスリリース|理化学研究所
Riken's press release on the Fresnel lens solar thermal wankel rotary heat engine. Apparently the lens tech is fairly advanced, being developed as a telephoto lens for observing high energy cosmic rays, with high optical transparency and a surface roughness less than 20nm. They used a three sided lens structure (top plate and two vertical plates), called a "Fresnel Sun House" to gather light well onto a T shaped thermal absorber/heat exchanger, even when the sun is close to the horizon at sunrise/sunset.

Apparently have a wankel rotary engine design that runs a rankine cycle using low grade waste heat. They did a demo with Riken using Fresnel lenses to create solar thermal heat concentrator setup to feed the wankel engine.

How Audi Hybrids Could Keep the Wankel Rotary Alive - Feature - Car and Driver
Wankels may have died at Mazda, but might possibly come back at Audi for generators in range extender options for EV's?

Guided Rotor Compressor
Very similar to a wankel rotor, but apparently not the same, and uses rollers at the apex seals. Hrm, I wonder why wankel rotors don't use cylindrical roller seals for the apex seals?

GM Planning Rotary Power Plant for 2nd Generation Chevy Volt….Did we Miss the 1st Generation?
Interesting report of GM looking at a high density powerplant option for the followon Volt vehicle. A wankel rotary is interesting, but the main expertise for that is Mazda, so there would need to be a tech agreement. I am a little surprised by the drivetrain cost issue with a microdiesel. Small diesel generators for boats don't seem to have such a cost issue, and this is a series hybrid vehicle so it should be a drop in replacement. I'm also surprised there isn't a return to a microturbine. GM has some turbine history, and Capstone is a small enough company to buy outright. Capstone, or WilliamsJet, have great tech for single piece milled turbines.

Seems Cermetica is working on advanced high temperature titanium diboride ceramic coatings for the purpose of an advanced wankel derivative motor with high efficiency. Seems to be a continuation of research by Katherine Logan and Robert Wisner.
