Optimization Finished! New Turbine Images and Power Curve Here

Optimization of our turbine has been finished! First off, a big thanks to everyone who's participated in this round. Your investments helped bring this optimization project over the finish line. While the final report containing the supporting mathematics is still being written, these are renderings of the updated turbine and calculated power curve (below).

The lessons learned over the past several years have culminated in this final version of our turbine. It has been mathematically optimized for maximum power generation given its desired form factor. It has been enlarged and simplified to reduce cost and complexity of manufacturing and assembly in addition to being optimized for power generation.

The power curve below represents the calculated power curve of the new design. Although the blade is still being worked out, the power curve estimates a conservative 35% efficiency of the assembled turbine when working in conjunction with rooftops and structures.

This final model is expected to generate significantly more power at any given wind speed vs the power curve of the old turbine (which is still shown in the main section of this raise). Also, while data from competitors is fairly nascent, I believe it will be at least competitive with, if not superior to, similar models either on the market or currently in development in terms of power generation. It also stands to be simpler and less expensive to both manufacture, ship, store, and assemble than comparable turbines.

Of note, the top no longer contains a separate section designed to emphasize negative pressure above the blade. While this was an early expectation of the design, Espiritu discovered a way to eliminate it while generating more negative pressure above the blade than with the apparatus. This is a significant development as it allows a greater collection area for the same total height and yet places an even greater emphasis on negative pressure above the blade.

The models shown on these rooftops are quite large to compete with upcoming models from competitors. However, the design was created with scalability in mind and a smaller turbine for residential rooftops is expected to be released alongside or shortly after the larger commercial version, depending on how much tweaking is needed to make a smaller version viable. I don't believe there will be much if any changes needed for a residential version, except for maybe the mounting hardware. I ran some preliminary calculations last night and believe that this will be feasible.

Beyond the turbine, Halcium has been accepted into the Four Corners Cleantech Accelerator program. This incubator was created by the US Small Business Administration (SBA) to help further innovation in clean energy. We were accepted just a few weeks ago and are getting started in the 10 week program. This will help us further increase our connections in the clean energy markets, engineering expertise (as needed), and business contacts in cleantech generation sales markets both in North America and in Europe.

Last, I'm very pleased and fortunate to announce the creation of a formal advisory board. Two outstanding professionals have been added in the last couple of months.

Jared Thomas (linkedin.com/in/jaredjthomas) has joined the advisory board as the Chief Technical Advisor. He currently works at the National Renewable Energy Laboratory (NREL) and has a PhD in mechanical engineering with an emphasis in optimization, fluid mechanics, and wind energy. He'll be advising on the overall engineering of the turbine as it moves to the final mechanical and electrical engineering to ensure it will last 20-25 years on a rooftop.

Brandon Bingham (linkedin.com/in/brandon-bingham-625a6139) has joined the advisory board as our Chief Operations Advisor. He has extensive experience in manufacturing, operations, and creating go-to-market strategies for complex products with highly technical sales processes. He'll be advising manufacturing and creating a solid go-to-market strategy.

Over the next weeks I'll be expecting the final report on optimization (a lot of very technical, very boring calculations) as well as a proposal for the final mechanical and electrical engineering of the turbine (cost and timeline). I also plan to build a smaller-scale version of the prototype for testing vs the calculated power curve.

Again, I want to express my appreciate to everyone who joined this round (and previously) because you made this possible.

I see a clear path to the finish line with the completion of this milestone. In addition, I think it looks amazing. With almost no publicity outside of these raises, we've managed to generate global interest in a novel product poised to create value in an already $300 billion USD annual market which is growing at 14% a year. Large corporations, governments, and individuals have all shown keen early interest in our turbine and I believe this final turbine and its data will only stoke those flames.


Well done!!! Just a question: How would it behave in very windy conditions? I understand that traditional turbines have to be switched off because they can break down.
The plan now is to include a converter and small charge controller in every turbine which will stop the generator from overproducing. In addition, there's a consensus that the opening will passively prevent too much wind from entering the blade.
Looking good, but the small footprint at the bottom would probably make it vulnerable to high winds or at least require a very sturdy fixture. This could be a challenge on many rooftops.
Agreed. Mechanical engineering of the internal structure and mounts will continue to inform the design's base.
What are the dimensions of the 2 kW turbine?
The commercial version is looking a little over 4 m tall. Residential closer to 2 m tall.

Awesome thank you for the update!@@
This is the result we have been waiting for. I'll be looking for our turbines on rooftops now.
Great progress!
It looks beautiful 🤩
Congratulations on the optimization and design! The renderings looks great. I'd like to install commercially and on my home residence when available. Keep up the good work and momentum!
I’m really looking forward to using these in the design of my new home!
