The use of exploding fuel is probably ineficient and in
any case is noisy, pollutive and hazardous (at least to
the environment, see 'oil spills', 'smog' and 'car
explosions').
So the proposed motor here is to work on slow heating
fuels such as compost, manure and hot roofs.
I'm not quite
sure of the exact process to harness that
heat. Actually I have several ideas, but would like to
hear other ideas for this:
First, all living and even vegetative beings use a similar
process, by using ultra eficient "nano-motors" - creating
ATP from sugar and then consuming it in the muscle
cells. Perhaps we need to create mini (not necessarily
micro) steam engines. Or maybe use material expansion
from heat, to get a motor to move. (Maybe heating and
cooling). Perhaps the energy could be used with a
transmission system to cause wheels to turn...
New Rotary Engine of Disruptive Technology Type

This is the simplest eccentric-rotor configuration with rotor as the main or major moving part and the hydraulic oil as the motive power supply. [rotary, Mar 29 2008]

My thoughts were similar when I proposed the two-stage beer engine powered by evolved carbon dioxide during fermentation. Slow but powerful is almost certainly the way future engines will run - very high torque at very slow revolution rates, possibly with the engine running 24/7 and storing the energy elastically for power-on-demand applications. |

Interesting. Cylinder (or what have you) leakdown would be a significant issue - I'm thinking a captive working fluid heated externally, like a Stirling. |
|
| |
Huh. Could you get enough memory wire going to make this work, say some of the springs? Slow is the word, but relentless. |
|

I think this is a wish in search of an
invention. |

Here is a much better insight: I have invented a very fast burning, extremely efficient rotary engine for a very slow burning fuel like mineral oil, diesel, bio-diesel, or straight vegetable oil. This could be the practical scenario equivalent to your proposal: the fuel oil is quickly consumed by my hybrid engine design--much like sharks do to blubbery seals; then energy is stored in hydraulic accumulator--much like calorific cells come closer to the muscle tissues as stored fats; then pressure is released to the hydraulic motor by fast-response valve system opening appropriately depending on the power demand--much like a how able a shark flips its tail, either for slow cruising speed or for chasing prey. |

Check this out for future reference:
Blog of my "New Rotary Engine of Disruptive Technology Type".
Check out the link I supplied. The future of rotary engine is brighter than ever! Would you agree? |

Um the btu output of a compost pile, while surprisingly high is not going to move that pile anywhere at all fast. The energy/weight ratio of raw biofuels is pathetic. Add in a slow and incomplete method of extraction that happens only at relatively low temperatures and..... you have a horse. Get over it. |

Do i see 16 apex seal and 32(36?) planetary seals? How do we get the air in? do the rotors float? How do we start it? |
|

WcW, the tightly fitted outer rotor walls (or cladding), the inner housing four contoured apexes/tips and inner rotor three contoured apexes/tips act as seals: They can be separate and spring-loaded in larger models or integral feature in thinner and smaller ones. The air is channeled in through air filter then to the suction chambers as intake ports in the rotors are inherently uncovered by its unique movement. The rotor components are fixed by a single bolt and aligned by three pins while assembled together with the housing. Starting is achieved either by hydraulic means (by reversing the hydraulic pump), or by pneumatic means (by introducing compressed air to the turbine side). |

[rotary] I hope all your ideas have the same amount of carnivorous metaphor. |
|
| |
Oh marklar, all of them have. These "New Engine of Disruptive Technology" concepts build into one formidable invention are equivalent to lone monster shark among the carnivorous seals representing the conventional engines and the newbie hybrid technologies! Sad metaphor, I think… |

Heat engines are more efficient with greater temperature
differentials. Therefore, I expect a slow-burning-fuel engine
would be less efficient, because it wouldn't get as hot. Also,
if it was more efficient, we'd already be using it. |
