Open-source equipment prints solar panels every 15 seconds

The idea of open-source energy technologies gets more and more support of the inhabitants of our small blue-green planet 😉 . The two inventors of the Philippines – Shawn Frayne and Alex Hornstein (Shawn Frayne and Alex Hornstein) developed a “pocket” factory for printing small solar panels.

Shawn and Alex have developed the equipment that allows to automate the manual labor and the layout of small solar panels that are used in household appliances. According to them, this is exactly what will make the solar panels more popular because they are too expensive at the moment. Due to the large component of manual labor, small panels cost $1-2 per installed watt of power. At the same time the price of large panels is $ 0.65 for 1 watt.

The equipment that is being developed by Shawn and Alex is quite productive – it allows to print one panel segment every 15 seconds. But most importantly – it allows to do this in a home lab or in the garage!

Two inventors have received funds to develop their own equipment on Kickstarter and later they plan to make the technology open and cheaper. We are glad that there are like-minded people and looking forward to release of a new open energy technology! A little more information – the video and the links below.

Help our hackers to make the world greener!

By providing our hackers a mirror or materials to experiment with solar concentrators you’ll help with making solar power more accessible

Not only technology

Sunny hakathon SunnyDay is not just a competition between teams of hackers to win the prize. It is not only tech creativity and work on the best concentration scheme.


The desire to share knowledge and skills, the results of work with others is at the heart of this project. Therefore, participants will publish the results of their work in the form of open-source schemes, instructions “How to…” and other documentation.

We will share our work with the whole world, because we believe that the possibility to freely use solar energy and energy democracy – is worth investing time and effort. We believe that over time, our present experiments will grow into new businesses, social and private projects. And everyone without any exception will be able to use the results of our work.

Old mirror? – Give it to us!

In order to ensure our teams have the greatest possible scope for experimentation, we ask for your help. SunnyDay budget allows to buy certain amounts of materials, but the number of registered teams tells us that we need more.


 Please help hackers with the materials – and they will share with you their knowledge and results of their hard work.

We don’t need any new or extraordinary materials – just look around. If you have an old mirror, or you don’t know what to do with the old satellite antenna – we will be happy to help you to get rid of it. Whoknows, maybe thankfully to your old / unwanted thing some team will win $1K and make the best concentrator?

Most likely somewhere in your garage you can find things that will be useful for our hackers:

  • Glass mirrors  (including small)
  • Plastic mirrors (eg acrylic mirror)
  • Other mirrored surfaces
  • Old satellite antennas
  • Different types of binding
  • Tubes and pipes of small diameters
  • Slim fitting
  • Bolts, screws, brackets, binding
  • Left overs from USS Enterprise or international space station;) – kidding :))
  • Other

Where and how to give it?

If you have something from the above list and you’re ready to share these materials, here is what you should do:

  1. Take a photo of what you have
  2. Send this photo via email to zinchenko.andrij [at] with topic “materials for hackathon”
  3. We will contact you and agree how we can take the materials

Thank you!

Thanks in advance to all who respond and support our hackers.

EnergyTorrent and KHackerSpace (Kharkiv) started joint steam engine assembly

Since the last week EnergyTorrent along with Kharkiv-based KhackerSpace started joint effort to assemble a first steam engine. Mykola Khrystenko – one of the active participant of Kharkiv tech community is the leader of the project on the side of our Kharkiv partners.

Steam engine is one of the important components of the renewable energy construction set that is being developed by EnergyTorrent team. This well-known and well-tested technology (which is also very reliable) can be used in various applications. Efficiently transforming heat into mechanical energy steam engine can be an important part in generating mechanical and electric energy in cases when the thermal energy is available. The source of the heat can be, for example, solar light or burning of the biomass.

For now we have taken as a base an existing steam engine developed by American inventor Robert Green.We can not share his technical drawings, since the copyright belongs to him. Though, machining and assembling this type of a motor is an important start for us. After testing it we will be working on our own versions of steam engine which will fit best the needs of using renewable energy sources.

And once again – EnergyTorrent is an open project, so if you are interested to join the team working on our steam engine – we will be more then glad (yah, that includes cookies). We are also open to new ideas, so if you are ready to propose an implement new technical approaches or technologies – you are also welcome. Join in!

First Stirling engine running

It is already two weeks that EnergyTorrent is testing its first Stirling engine. We have given it dosens of testings and it seems to work pretty good. Here is a short video demostrating one of the first runs of our Stirling engine.

We have used one of the freely available technical drawings to make this Stirling engine. It is far from high efficiency, but it is a good start for our project 🙂
