Crowd funding

Whats the idea?

So, the idea is to build a large 2 kW engine with crowd funding. Why? Well, firstly because it sounds like fun. No such engine has ever existed, so having the first of its kind sounds good too. And bigger is better.

We would also like to have a full scale engine to see whether it works; there are some aspects such as sealing a comparatively large diameter piston which need to be done to figure out how it works.


In the next step,. a two-cylinder engine will be designed as a semi-commercial machine. The two cylinders will have a much smoother power output, suitable for grid-compliant electricity generation.

Then of course we aim to develop a commercial version, for which we need more funding. What better way to convince people than having an actual prototype working?

The way forward we see is to start with a crowd funding project. I estimate that we need around 40,000 Euros or $55,000. One of the purposes of this website is of course to raise awareness for the technology as well as to prepare the crowd funding project, which we intend to launch in April 2017.

Why a large engine?

Currently, we are stuck with small scale models. This is unsatisfactory fir a number of reasons:

  1. It is difficult to convince people that the technology has potential with small models only.
  2. Friction and heat losses in small models tend to be proportionally larger than at full scale. This has something to do with the fact that the surface-to-volume ratio becomes smaller as the engine gets larger (heat losses), and that friction losses are approximately constant, but actual power reduces as the model gets smaller.
  3. We need to know the costs of a full scale machine in order to determine its cost-effectiveness.

Why should people contribute?

  1. Well, we are developing a new technology for renewable energy which promises to be simple and cost-effective thereby giving renewable a boost.
  2. You will be in the forefront of knowledge, if you are interested in the development of heat engines for temperatures between 80 and 150°C.
