North American Rocket Stove
Its been asked how the hot gases would move through the stove for the different modes of operation. The stove needs to be controlled for damping, creating draught, warmup, oven baking, stove cooking and water heating. Its tough to show in 3D how the gases will move, but the diagram gets us a start in thinking how the controls are setup. No electrical, just dials that open or close internal baffles. The iron plate housing the three control baffles will need to be 1/4" thick to handle the extreme high heat from the burner tube. The heat will be absorbed and radiated to the oven when all baffles are closed.
Rocket Stove / Patsari Stove
Lynx Steam uploaded a video on a rocket stove to YouTube and it has over 250,000 views. This is five times more than the next most viewed video on Lynx Steam's channel. Why?
The Patsari stove operates on much the same principle but is intended more for cooking. Patsari means "cares for you". It burns less wood, burns clean and doesn't pollute the kitchen with particulate matter like an open fire.
The Patsari stove was designed specifically for the type of cooking done in Mexico and surrounding areas. With a little redesign the Patsari/Rocket stove can cook, heat, heat hot water and pump water.
It can also be the aesthetic focal point for the modern North American kitchen.
The stove is made with cement board, lava rock, steel and tile. It can be made with bricks instead of cement board and tile. It's basically a one or two weekend project.
In North America we are used to a couple of burners and a stove for baking.
The principle behind this type of stove is to first completely burn the combustibles by confining the fire in an insulated burn tube. The temperature is sufficient to burn clean and complete before the hot gases are cooled on non insulated burner plates, heat absorbing clays, or water heating tubes. As the hot gases give off their heat the velocity of the gases slow and cool. After the work is done, the relatively cool exhaust goes up the stack and invisibly exits out. On a cold day you might see the steam in the exhaust condensing.

Energy Efficiency
Part of the problem with wind and solar power are that we come at them with the wrong mindset. In the context of cheap abundant energy, neither wind nor solar make much sense. If a kw of power costs 20 cents, then why bother with a solar panel or wind turbine that makes only a few watts?
In the western developed world we are conditioned to not even think about how much power we use. Try making 20 watts sometime, you will be amazed at how much effort it takes. To get 1 hp/750 watts out of a steam engine takes a constant roaring fire.
In certain situations it would be nice to have power. On a boat, camping, at a cottage, or during a power outage.
But then the problem arises. If you come at wind or solar as if you are going to run your normal life it takes 2-6 kw. That is basically running a 5-10 hp engine constantly which takes gasoline or diesel.
Now, if you approach wind or solar from a different mindset, "what do I really need and how can I fill that need as efficiently as possible?", then you will be quite impressed with the freedom there is in knowing you can supply your own power with energy all around us.
Basic needs:
heat, water, light, food, shelter
Wind and solar can take care of water and light, and small appliances and conveniences such as laptops, radios, and there are some nice 12v refrigeration systems now.
Investing in a system that turns at least one room in your house into a "free energy room" makes sense. In case of a power outage you have a comfortable room with lights, entertainment, small refrigerator, possibly a wood fired stove/fireplace as a backup.
This page will be a place to give you some ideas for using free energy as efficiently as possible.
