Thank you for sharing the microscopic batteries idea! I will definitely keep an eye on this technology as it's been something I've been looking into for a while (i.e. batteries and hydrogen fuel cells harnessing hydrogen from the natural microbial environment).

As for the digital display goggles / contact lenses, I'm happy to see more people working on this other than tech giants Microsoft (Hololens), Facebook (Oculus Rift), and Google (RIP to the late Google Glass). While it is still a long ways away due to the challenges of nanotechnology and biotech (as well as public accpetance of having a nano-circuit embedded in their eyes...), I cannot wait to see these souped-up contacts on the market 10- or 20-years from now.

Same goes for the electric airplanes, which are a much larger polluter than ICE cars.

Definitely resteeming this.
