Neptune – The Autonomous Sea Drone

This is the first project we start with, when we found “The Rare Blue”. More than one year, we are designing an energy independent vessel, powered by renewable nature forces for research and exploration. It will allow us to travel all the way of the water, from rivers troth the seas to the ocean, without spending thousands for fuel.

Today, instead of creating a large expensive boat, we focus our work to design a so-called “Sea Drone”, a robot able to go everywhere on water, dive underwater and explore the water-world whatever we send it. It will use renewable energy to recharge and basic intelligence for autonomous control.

Drawings and info from stage of development you can find below, or in our “Captain’s Log”.

Update from 1 of October 2019
Long time no update. This doesn’t mean that the project is halted. The truth is that along with the development, there is less and less time to publish the work.
However, there are many new things.
First is the new look of Neptune and the new technology used for its building. Unfortunately, there was no easy way to make the old design working underwater.

The new design will not only be able to operate both underwater and above, but also to move with very little energy. It will be equipped with instruments to explore and interact with the underwater environment. The purpose is to find a way to make an autonomous underwater explorer and environment improvement and protection assistant, growing underwater food and helping endangered species.
But there is more… The new underwater robot is designed to be completely open-sourced and DIY (do it yourself). All the drawings, sources and instructions will be shared here, so everyone who want to work on improvement of this idea to be able to do it.

Update from 30 of November 2018
There are a hundreds of different sails setups, each one efficient in a specific conditions. But I needed a sails that are simple enough so I can control them easily.
You will also see that I’ve changed the boat from “biplane” to a single sail in the middle. It’s because the solar material I found is able to produce electricity from both sides.

Watch all the series here:…

Update from 10 of October 2018
Hi guys! After one amazing summer I came in Scotland again, filled with new knowledge and experience. Here is the new concept of the prototype. We decided to create a smaller research solar catamaran, to use it for our “inshore” traveling on the rivers and the sea coastal, following “the Way of The Water”.

Now after finishing the “biplan” sails design, I will focus on the hull. So stay tuned, because new sketches are coming soon.

Update from 1 of May 2018
We finished the design and calculations of our 25m long solar cruiser.

Because we are not able to finance it’s building we will start design a smaller prototype which will cost 20 times less. Update soon.

Sustainable Laboratory

Our first laboratory is now building in Varna, Bulgaria. It is placed on area of 60 square meters and is planed to be finished in December 2018. Because of our green mission, we decided to make the lab absolutely independent, powered by wind energy and collecting and filtering rain water.
If you are visiting Varna, Bulgaria, you can spot the construction work from the top of the bridge “Asparuhov Most”, on the right side when you enter the town.


Newest in the Lab is the Lightboard we’ve built last week. Now we can easily develop our new ideas and strategies. And because we’ve made it really good and low-cost, we’ve share all the instructions how to built one for yourself, here:
Wind generator is now ready to make us some electricity…

Such a beautiful day in February! I decide to test our “big door” and the view from it…

We now cover the frame:

The frame we built from steel pipes, connected with screws.

Microplastic Filter

We are developing a clean-up system for the ocean’s enemy number one – the microplastics. The systems will be placed inshore and offshore from our partners “Team Seasteps“, while they sail. More info and drawings are coming soon.
