This free DIY manual shows you how.

Our DIY kits come with pre-assembled components for your own DryCell with assembly instructions. You just need to add distilled water and a battery (or any other power source). Assemble with common workshop tools. Note: The DryCell kits are hand made by our German team. Please use an online translator to order.

Why do you give this away for free?
The knowledge has always been Open Source, free for everone! We just recreated the principle and now share it with the world, to make it a better place.

Are these fuel cells?
No, they are exactly the opposite! Fuel cells make electricity from oxygen. The DryCell makes oxyhydrogen from water and electricity.

The DVD won't work on my player!
This is a dual layer NTSC format DVD. If it does not play in your region, try watching the film on a computer or chose the free download version.

I want to become a member of your organisation!
We are no association. There is no membership. We are a free group of friends trying to help the planet before we leave.

The electrolysis is an inefficient loop way! Why not heat electrically?
This is outdated, that's from 200 years ago. Now we have much more efficient materials and equipment, even from the local hardware store! And as we know today, the energy from the oxyhydrogen is already stored within the water. So the electrolysis is just a stimulus for fission, and this is no closed energy circle at all. We explain this in the DIY manual.

Where can I find such DIY workshops in my area?
The DryCell is Open Source, so anyone can join in, replicate and develop free of charge. So we usually do not know who is offering workshops.

Why do you call this a 'DryCell'?
The unit is traditionally called a 'DryCell' to distinguish it from Michael Faraday’s 'WetCell' from the 1830's. Of course the DryCell also uses water for the electrolysis, but only very little. It is much more efficient.

What is the 'WetCell'?
An older variant from Faraday's times. The Audi car owner also uses one in his car. Basically it is just a jam jar with a spiralled coil inside. We think it is rather ineffective.

Can I use the DryCell in my car to save fuel?
Usually yes, depending from your car's engine. Consult your car mechanics to see if this works with your engine. Also please check if this is legal in your country. See the DIY manual.

Can I use the DryCell for heating?
Yes, and we even explain a lot of fascinating heating experiments in the DIY manual.

What else can I do with oxyhydrogen gas?
You can flamelessly heat with our DIY sand heater, use it for welding, melting (even tungsten melts within seconds!), you can boil water (the flame even burns underwater), use it as a lime light, you can power combustion engines and even remove radioactivity, and lots of other fascinating experiments. We explain ALL of these experiments in the DIY manual. You will definitely love this.

I want to store this gas.
Don't work against nature. Hydrogen (H2) has the smallest and lightest atoms of all. It instantly ascends and dissolves through every material, it even goes through walls and roofs right into the atmosphere. This makes storage totally useless. So we never store it! We simply make it on demand.

Aren’t there patents?
The DryCell is a free invention, free of patents (they are long expired). It is even Open Source. So anyone can join in, replicate and develop free of charge. No more secrecy. No more hiding! The knowledge is out there anyways, and the invention is even protected by an international safeguard organisation.

What’s the efficiency of the DryCell?
A decent DryCell draws about 130-160Wh to make 1 litre of oxyhydrogen gas per minute. This is about 390-480Wh for 3l/min. of HHO gas, or approx. 650-800Wh for 5l/min. Skilled hobbyists can absolutely undercut these values. But we don’t really think about efficiency at all. We do this for self-sufficiency and a better planet. And we love to do experiments.

Are there scientifically approved measurements?
We are in contact with established Universities in Europe. But they work at a very slow pace. We are hobbyists with a working device here. We are still waiting for their explanation of what is really going on here. To all doubters: Build and measure for yourself! You wouldn’t believe us anyway, right?

You can't power cars with this, or heat efficiently. Never!
Of course we can. This is no closed energy cycle, so there is no violation of any energy conservation law. And we have far better materials than Michael Faraday, even from the local hardware store. All the energy is already stored within the water. Ignoring water as an energy source would be like ignoring the fuel in a car, and then claiming the car would run on battery.

Why didn’t we hear from you in the news?
There are powers in charge who want to keep you down. More in the DIY manual.

What are the DIY material costs?
Estimate 400-500 USD for the DryCell, depending on make and size. Add 250-300 USD for a power supply, or use a car battery or photovoltaic batteries. And you will need some common tools to assemble.

Where to obtain all the parts for DIY assembling?
At your local hardware store. Some parts you might also find in computer stores or wholesale markets. Improvise. Nature is not standardized. In case of trouble, team up with neighbours, work colleagues and friends. This will reduce costs and is much more fun, too.

Where can I find others?
Look for like minded people among partners, friends, neighbours and work colleagues. It’s about time for synergy and cooperation! And of course there are a lot of HHO web forums. We do not even watch these forums.

How to power the DryCell?
You can use a car battery, a stand-alone photovoltaics system, a switching power supply (for power grid use), a toroidal transformer, or whatever you find is appropriate. Improvise! You will find a way.

How much Volts/Amperes does the DryCell need?
Our DryCells draw 3-5A only for most applications (welding, underwater flame, flameless sand heater, limelight,...). In the first minutes during a power up, a cold DryCell can easily draw up to 15-30A, if you just let her. Under working conditions our DryCells typically draw 1.7V-2.4V per chamber, depending on the operating temperature. We strongly advice to build your DryCell to match the existing power supply and intended usage.

But this gas is explosive!
Yes, this is exactly why we use it. We respect nature and we are careful in what we do. We work in small scale, we just produce on demand, we do not store any gas and we take good precautions to stay safe. Remember, this is a technical experiment with chemicals, electrical energy and fire. These are real energies we are working with. But we are all grown up and responsible. So team up with friends, neighbours and work colleagues! This is much more fun together and it will save you a lot of money, too.

I have no technical experience!
Decide for yourself if this is something for you. This is not intended for the average customer who demands off-the-shelf solutions. We show you technical experiments which are still undergoing development (as is the nature of Open Source). They can still contain errors and are therefore intended for adults only. You will need technical skills, patience and enthusiasm. Team up with colleagues, friends and neighbours, this is more fun and makes it easier. Consult an authorized specialist if you are uncertain what to do.

They say on the web that this is just a hoax.
Lots of people rather believe in theory than in reality. Some may even be paid debunkers. Who pays debunkers to run down Open Source...?

Why does the hardcopy manual cost money?
You can download everything for free, see above. The costs for the printed manual and the DVD just cover the manufacturing costs. That's all.

This is not a technical hotline. Please note that we may only react if you are nice and decent.
