Flash pyrolysis is used primarily to yield a higher oil output and lower gas and char outputs.
The Molten salt flash pyrolysis reactor will use molten salt at a temp of 450-550C to gain optimum bio-oil yields.
A: The biomass will be a closed container and will feed the biomass into the molten salt.
Variations in design: The feeding system can use a screw feed or an air feed system. The biomass will have to be very fine, under 1mm in size. If need be nitrogen can be used to keep the oxygen levels low, but it may not be necessary.
Variation in design: The biomass can be fed and injected underneath the molten salt or over top. If the biomass uses a screw feed and it places the biomass on the surface of the salt, then a cyclone effect or blender mechanism must be added. This will ensure that all the biomass is quickly brought underneath the molten salt and ensures the highest possible bio-oil yield due to quick reaction times.
B: Reactor with Electric heating coils- the molten salt will be placed in a sealed, insulated, and coil lined electric heater. This will ensure less heat loss and digital control over temperature.
C: When the biomass is added, the container will begin to fill due to the added volume. Most of this will be small particles of char. At timed intervals, an electronically controlled valve will open and release the molten salt. If the reactor is much larger than this will be done over longer intervals.
The released molten salt will run through a high heat, high speed centrifuge. Because the salt is liquid it will separate in the centrifuge with the char. The char solids will collect in the centrifuge while the liquid salt flows down the pipe
D: A high heat pump will pump the salt and inject it back in the reactor.
E: The vapors will rise through the tube at the top of the molten salt reactor. The vapors will condense using either air or water as a cooling agent.
F: After the gas is condensed to oil it will be collected in a storage drum.
The remaining gas that could not be condensed can be run in a generator maximizing overall efficiency of the system

Pyrolysis Reactor for Waste Disposal

This same reactor can be used for waste pyrolysis. There are a couple variations. The temperature of the furnace will be much higher, over 1000 degree Celsius. Particle size is not much of an issue because reaction time is not important. The smaller sizes should result in quicker pyrolysis.
The main component out of this high heat pyrolysis system will be gas, char, and very little oil.
The other components will remain similar.
Variations can be made in feeding speed and temperatures to gain desirable output.

Garbage, plastics, papers, tire wastes, animal wastes, sewage waste (reasonably dry), etc.
Above are the different items that we can turn into char and also keep the landfills clean. The system should be efficient enough to create surplus electricity once continuously fed with these items.

*Flow rates, feed size, temp for optimum oil yields, etc will be determined when a prototype is built.

The pictures explain different variations of the kite wind generator.

The generator is in the center of the track and the poles are connected to the vehicles that sit on the track. As the kite pulls the vehicles it turns the generator creating electricity. The shorter the track, the more efficient the system will be. The kites can be operated manually by a driver or automatically such as Skysails.
Another alternative of this system (not in the pictures) is to eliminate the generator in the center and have each vehicle contain its own generator. This allows the track to be any size and shape because it will be creating electricity as long as the kite is pulling the vehicle.

Boat Kite Generator
This idea holds the most promise. Each boat has its own individual generator. As the boat is being pulled the water turns the blades of the turbine. A body of water will not need a track and each boat can have a large cable that it drags to transfer electricity onto the grid. The kite can be flown manually or automatically such as Sky Sails.

A variation of this system (not in the pictures) is to have a track suspended over the body of water. The vehicles would be placed on the track and the generator would be attached to the vehicle but placed in the water. This would give a directional track with the efficiency of using an underwater turbine.
