Assuming the organisers read this forum, or Hal or Zack communicate suggestions to them: I've just received an e-mail outlining the route the solar-powered 'Solar Impulse 2' will be taking on its round-the-world flight. It says they intend to make a stop-over in the Midwest 'dependent on weather conditions'. The timing might still allow for a stop-over during AirVenture.
I understand that during the visit of 'Solar Impulse 1' to the US in 2013 there was some interest on their part in visiting Oshkosh. Since that project, to my mind at least, epitomises innovation and success in the field of non-fossil-fuel-powered aircraft, perhaps the EAA could invite them to make their Midwest stop-over at Oshkosh during AirVenture?
