Solar Powered Steam Generators

Our good Friend Robert Saunders has done it again. A few years back he published a document on slotted turbines that generated a lot of interest:

http://www.green-trust.org/steamturbine/steamturbine.htm

Now he’s come up with another gem, electricity from solar produced steam.

And now on 2/25/09, another chapter to the continuing saga:

It’s a good read, and we recommend it.

[Green-Trust CHP] The Green Steam Engine

A friend of ours turned us on to a simple and easy to build steam engine. Called the Green Steam Engine, it’s simple and novel design appealed to our DIY approach. We can burn veggie oil in a turk burner to produce the steam, or even boil water on a wood stove. The engine can then turn one of our axial flux permanent magnet alternators to charge our battery bank. Clean, quiet, and sustainable.

DIY Bladeless Disc Steam Turbine


Build Your Own Bladeless Disc Steam Turbine Generator

Need for Decentralized Power.
The reader can be certain there is competition to develop new and innovative products that promise to reduce our reliance on foreign oil and gas. One way to reduce this dependence is to generate our own electricity from local energy sources, such as solar energy and biofuels. What is needed is a way to decentralize production of electricity to reduce our dependence on the grid. If every household could do that, we would succeed in meeting the stated energy goals of every President and Congress of the United States for the past thirty-five years. So far, that has not happened and here is a way to take one positive step in that direction.

An opportunity for all.
This is an opportunity for anyone with the right skills to build a small 5KW to 10KW steam turbine for less than $200.00. The cost of adding a generator or alternator will partly depend on the size of the unit and the amount of power it can provide. What should be important to the reader is that the author is willing to share this information with anyone interested enough to take advantage of a proposal for becoming part of a select group. This may end up becoming a pioneering effort by those who participate, but there are no guarantees.

Making Steam from Solar Energy – redux

A while back, Robert Saunders sent us an article on a steam turbine he was working on. Then he sent another on solar energy steam electric. Well, here is his third chapter in this continuing quest. Hope you enjoy:

How propane refrigerators work

We use propane fridges in some of our smaller off-grid installs. The electric fridge is a big electricity user, and although propane is not renewable, it’s often a first step to getting off the grid until your PV system is built up to the point where you have the capacity to run a energy star electric fridge.

The ammonia and water is heated by a propane flame [which is why it is called a propane refrigerator] thus causing it to vaporize into a steam through the perk tube. The process that this steam is being perked, is similar to a coffee percolator. The inner tube [perk tube] in the boiler emits steam & water bubbles moving upward. Since the ammonia is lighter than water, the ammonia will turn into steam sooner then the water will. This ammonia steam is pushed up into a condenser by the hydrogen pressure while the water falls down into the outer tube and is pushed into the absorber tubes which then returns to the mixing tank [absorber tank]. As the ammonia steam is moving upward through the rectifier and on into the condenser tubes it again turns into a rich ammonia liquid. This rich ammonia liquid is pushed into the top of the evaporator tubing. After it is in the evaporator it meets the hydrogen gas moving up through the inner tube inside the evaporator. This hydrogen gas absorbs the rich ammonia. As the ammonia meets this hydrogen gas in the evaporator it creates a chemical reaction . This reaction evaporates the ammonia thus making it extremely cold at that point. This is what is called absorbing the heat, or better stated, removing the heat from the refrigerator box.

Invention of the Month – The Green Steam Engine

This one has been around a while, and has met the test of time. It’s a reliable design, and we think it’s awesome. See more at http://www.greensteamengine.com

Solar powered steam turbines, the saga continues!

A while back, Robert Saunders started a series on solar powered steam turbines for electrical generation. That series continues:

Back from the Energy Fair

Pearl Steam EngineWe just returned from the North Country Sustainable Energy Fair, where we taught classes on DIY Wind Turbine design and DIY Solar installation. We saw a number of really neat things there, and will be showcasing them here over the next few days. The one we want to talk about today is the Pearl Steam Engine. Pearl Steam Engines are a natural and superior power source for generators. The Pearl Single Cylinder Engine will easily produce 1 kilowatt. The Pearl Twin Cylinder Engine will easily provide 2 kilowatts.

    Utilizing the exhaust’s heat allows for co-generation. This raises overall efficiency even further. We highly suggest you take a look.
