Ivory Group invests in wireless energy transfer

Ivory Group has made an pre-seed investment in TransfoElectric - a startup which aims to develop novel wireless energy transfer method. 

"We believe we can achieve much better results than those currently available in on market", claimed Leslie Adrian, the Riga Technical University lector in magnetism and robotics, who's going to lead the research on the project. 

Current wireless power transfer (WPT) technology is limited to extremely close distances. Various technologies are being developed all around the world, including classic magnetic induction energy transfer widely used in transformers as well as radio wave energy harvesting. However, for high power WPT applications like for electric vehicle charging, the only primary technology so far is magnetic induction. 

"We are developing novel [wireless power transfer] technology, which is based on coreless magnetic resonance principles first set out by Nicola Tesla a hundred years ago, and now is further developed by our researchers", stated Aivars Rubenis, a co-founder. "Our goal is to develop a true wireless power transfer technology -  not the pseudo-wireless energy transfer, which still needs charging pads.  People wanted to get rid of the cables, but instead they got another wired device clutching up their desktops.  Our technology will initially get rid of the pads - we already know that we can achieve that. And eventually, we hope, we'll be able to get to the holy grail - ambient wireless power charging, but for now our current focus of research is electric vehicle wireless charging".

Electric vehicle wireless chargers currently may be almost as efficient as plug-in chargers, however their major disadvantage is the cost and limited misalignment tolerance which makes them unappealing to customers in spite of the obvious benefits.  "Bringing the [wireless charging equipment] costs down is our main objective", stated Mr. Rubenis,” and we believe our technology will allow us to do exactly that."
