1 we are currently using saturated wet steam to power our turbine , steam quality can fall all the way to saturated liquid and our turbine is still expected to run

2 we are testing , will get back to you on that

3 also under testing but we have an idea . Its turbine specific and dependa upon blade configuration.


If you can identify the required toqrue requirements of your fan,  i can help you size an appropriate turbine

This page states that they plan to use steam....

It could be the present systems they have are too new for them to be selling product.

I'm going to contact them this week. I'll get back to you. I need to feel them out and see if they're legit. I need specs.

I bought the 4 inch 500 watt turbine of eBay for $120. So far it is working great with our flash boiler. Good torque and rpm this weekend hooking up to a 300 watt generator. Will post photos and updates.

We are building small chp for retrofitting biochar kilns. So farmers and communities can make biochar, electricity and purified water

It is very low cost and any mechanic can build it. If you are interested in building it our NGOs will reimburse you for  the materials if you publish step by step instructions and test results. Wastefree23.org

Start with your heat source - tlud, wood stove whatever,  take 40 meters of ss or aluminum tube.  Put tube in sand/clay that blankets heat source. Connect a Tesla steam turbine you built to one end with a pulley system to get the rpm right for your generator,  a valve and a pressure relief set at 150psi

On the water inlet side another valve and a pressure tank filled with water and a little air maintained at 100 psi or a 100 psi auto switch water pump

Great thread. Thanks

We are helping set up a simpler version of
This upcycling process.  Across Africa and Indonesia

Instead of an extruder communities are building very simple heat presses for $300 usd

They make waste bins, fence posts, roofing, drain pipes, bsfl trays and more

All plans and instructions are free at
wastefree23.org  as is instructions to upcycle and use ALL waste.  Plastic, organic, food, even diapers !

Great opportunity to eliminate waste and create lots snd lots of jobs

Hello.  There is a wastefree event in Florida end of March 2025.  Compost of waste will be presented. It would be great if bsfl and biochar were presented as well compared and contrasted with composting for organic waste

I am happy to support any speakers with research and materials.  Unfortunately I am not available those days to be in Florida.

Hope you can help. This topic is way too important to not be presented

Thank you

My interest is to get as much syngas as possible.  Therefore burning it to make the char is not my first choice.

Solar heat direct or from pv can dry the biomass and heat a kiln to 400c and with lots and lots of insulation the kiln will stay near that temp

To break the chemical bonds in biomass takes about 1 kw of heat per kg of biomass. Not to heat it up. Just to break the bonds

As many of you have said. When the bonds are broken syngas is released. When burned the syngas from 1 kWh of biomass can create 2 kw of power

I cool and condense the syngas and store it short term in an inner tube

This is pretty compilated for a single home. But on a farm that uses a lot of electricity or someone setting an a microgrid it is a way to double the energy from solar/ renewable. Have electricity 24 hours a day and a days reserve just in case. All produced with biomass. It is far better than burning stubble. Or a city putting tonnes in a landfill.  Plus the output is biochar. Lots and lots of biochar

Hi everyone. we have been working on this for awhile.  Now there are a few technical papers being written.  I have a 2kw system  in my backyard...

In summary...1kg of dry biomass/wood/manure/grass goes into a pyrolysis chamber which  is  heated by solar PV panel.  the chamber has a lot  of insulation around it so the heat is not wasted but used to break the bonds of the biomass to produce biochar and syngas.

Syngas goes to a generator or stored until needed in a few hours..or at night etc. then burned for  electricity.  

from 1 kg of biomass/waste....out comes 300g of biochar and 2kw of electricity:)  only input is sunshine and biomass .

what is your opinion?  any improvement?  is it time to get many  many more people, companies, farms and governments to build similar systems?

a sample of an article describing most of this system is here.  https://wastefree23.org/straw-pyrolysis-revolution-2kw-energy-from-1kw-input-carbon-removal/

Looking forward to your  comments!

I have started making biochar with a solar  concentrating mirror. Works great.  Minimal smoke:)

Here are photos of the setup. Pretty simple. More details are at www.wastefree23.org
