We have built and tested two model scale engines with 15 and 25 Watt power output, now we want o go bigger, building a 1/2 horsepower or 400 Watt engine. In order to do this, we’ll organise a crowd funding campaign, build the engine, then set up business. That’s the plan, anyway.
Our new engine will have a near commercial size. It will be fitted with measurement equipment (pressure transducers, power take-off monitoring) so that we can monitor its performance, and get reliable data. A 0.4 kW engine will require a 4-5 kW boiler, so we’ll get that too. This will be a commercial gas powered ring boiler, with a large pot as boiler.
The engine will have a Uniflow-configuration with a very simple control system.
With this engine, we can generate electricity, and we can determine the performance at near full scale (which may be different than at model scale). We also get a better idea of practical design aspects as well as costs. And, we can show it off to people so that we can get funding for stage three, the 2-cylinder version. This should give much improved power quality and also cost savings since quite a few components can be shared between the cylinders.
The fourth stage then is the company to develop, manufacture and sell the technology.
So what’s the time line?
Well, we needed to revise the timeline quite a bit. The experience with, and results from the Mk 2 engine have given us a great boost and design information. So, the new timeline is as follows:
- Start of project: November 2019. This involves the publication of a monthly Newsletter, the preliminary design of the engine, update of the website.
- Pre-campaign activities: we are aware that our project is very different from most other crowd funding projects, so we will need to work hard on the public awareness.
- Begin of funding campaign: Mid March 2020
