The item featuring Hungary’s Nanobus (Nanobusz) comes from a GE (General Electric) webspace devoted to Central and Eastern Europe (CEE). From their About Us page,

Communication is everywhere in the contemporary world. It can create understanding and forge common ground which can be beneficial for all parties. GE, as a company, is very much part of the global conversation through the voices of our experts – engineers, financiers, business leaders etc. Today we open an online multi-stakeholder dialogue about Central and Eastern Europe that builds on our offline experiences.

The Nanobusz, a nanotechnology mobile exhibit, opened recently in Budapest and was sponsored by the Hungarian Science Academy and GE Lighting’s Hungary-based Global Technology Centre. From the Sept. 23, 2011 posting by Ivan Hutter on the GE for CEE blog,

Why is the now 115 years old GE-Tungsram [GE Lighting] supporting the Nanocsodák (Nano Miracles) exhibition [on the Nanobus]? The answer very simple: because we are planning for another 115 years! The heritage of the Hungarian scientist society that was growing together with the now 115 year old Tungsram, the Hungarian light source manufacturer company acquired by GE in 1989, was also emphasized by László Balázs, Global Innovation Leader of GE Lighting, during the official opening ceremony.

…

For approximately 20 years now, within the GE corporation, more than 200 Hungarian engineers, and 24 graduate trainees from physics, chemistry and engineering faculties of the best Hungarian universities are working on developing energy efficient, environmental friendly products, such as LED light sources – not only for Hungary, but for the whole world.

In the Nanobus, there were built in more than 80 LEDs. These are the most innovative light sources available today, and we are proud to say that part of them is already a Hungarian patent!
