1.)
Some scientists talk as if iron nanoparticles were the low cost cure-all for groundwater contamination. Yet one study showed that in combination with carbon tetrachloride nanoparticles coated with iron oxide containing boron turn carbon tetrachloride into poisonous chloroform. Is there a safe Nano particle or Nano Process that can be used to clean up contaminated ground water ?
2.)
Using electron hole recombination and other methods different companies are working on making Solar cells more affordable. Affordable Nano Solar Cells could compete with current utilities and render them obsolete. What do you think is the best technique available to make Solar Cells more affordable for mass production ?
3.)
Can Nanotechnology improve petroelectrochemical hydrogen production
and make hydrogen fuel cells a cleaner, more viable alternative to fossil fuels for use in automobiles, planes, and spacecraft ?
4)
Have decoherence and the restructuring of the quantum properties of an entire system been factored into the current use of commercialy available Nano Products ? In other words, will renegade nano particles create unforseen effects on the ecosystem.
5)
What, in your view, is the Greatest danger and what is the Greatest benefit to the Environment from Nanotechnology.
