Pioneering Sustainable Innovation for Earth and Beyond.   We are a forward-thinking tech-based company, that develops novel technologies, to ensure viable and sustainable life on earth and beyond.   From Moonshot to Earth Impact:  Helios began as a space technology company with the bold mission to extract oxygen from the moon, with the challenge to enable the separation of oxygen from lunar minerals in extreme environments, where zero emissions are not an option but a necessity. Our efforts resulted in a breakthrough zero-emission process for metal production, applicable also on Earth – known as the Helios Cycle™.   Enabling Zero-Emission Iron Production: the Helios Cycle™ revolutionizes iron production. It produces iron from iron ore using mostly thermal energy, emitting only oxygen. This eco-friendly method requires significantly less energy, cuts costs, minimizes environmental impact, and maximizes existing resource utilization.   Beyond Iron: the Helios Cycle™ doesn’t stop at iron. It extends to other critical elements—silicon, copper, nickel, and lithium—offering a greener path for resource extraction.   Expanding our vision from our lunar origins, we’ve evolved into leaders in green steel innovation. Through strategic partnerships and collaborations, we’re poised to transform the trillion-dollar steel industry.   Follow us on this journey toward a sustainable future - on earth and beyond!

Doya Medical Ltd. is a biotech company that developed a non-invasive delivery technology and stent product for the treatment of Otitis Media with Effusion (OME). With 2 granted patents in the US and in Europe, and a validated animal model Doya Medical Ltd. is now seeking investment that will take us to clinical trials. Doya Medical is targeting a huge market of about 1 million ear tubes surgeries that are performed on children every year in North America alone. We aim to replace these surgeries by using an alternative device and the human bodys natural physiology. The eStent of Doya Medical Ltd. is an active stent used to drain fluid from the ear naturally and without surgery. Our kit includes the eStent and an optically guided delivery system for insertion into the Eustachian Tube. The overall cost of Tympanostomy Tube surgery is estimated to reach US$4B (Procedure Cost US$3547 + complication cost US$500). We Aime to change that with a patented, natural, non-intrusive solution. Like the heart stent, the eStent represents a revolution in treating OME-Otitis Media with Effusion. eStent places a stent in the Eustachian Tube in order to drain fluid naturally, supporting our body’s anatomy, rather than cutting the ear drum and inserting a tube. With our eStent you can go swimming, hear better and have less sensitivity to changes in altitude. Our experienced team has been developing the patented eStent and now has an animal model. The Current Treatment of OME is Tympanostomy (Grommet) Tympanostomy - Plastic grommets are inserted through the ear-drum under anesthesia. Benefits of the New eStent Procedure are numerous starting from it not requiring a surgical intervention and significantly improve the Quality of Life (QoL) for both child and parents
