"While one day we expect to have hoverboards that can effortlessly float over any medium (even water!), our current technology requires special types of surfaces."
so basically, they can hover something over a "special" surface, which is not that impressive
- julesaus 12y agoFrom the article: "Currently, this surface needs to be a non-ferromagnetic conductor." So the "special" surface needs to be anything that conducts electricity but is not magnetic, which is a pretty broad category. https://sg.answers.yahoo.com/question/index?qid=20120229051436AA6f9PS https://sg.answers.yahoo.com/question/index?qid=201202290514... has quite a long list. The images with the lego suggests that they're using copper, which is right at the top of that list for conductivity, but 7 orders of magnitude weaker is plain old sea water, so maybe hendo is not entirely joking about the hovering on water thing ;)
