The concept products and inventions that were showed to us during the morning presentation were amazing. The Nokia Morph phone 
was really cool because it completely revolved around nanotechnology and it gave me an idea for a possible product maybe something that I’ll just throw out there. I think it would be really cool if families in developing countries could be supplied with some sort of durable computer with “sense technology” such as this, that would thermoelectric converter of human warmth have many applications, such as detecting bad chemicals in the water because I know that is a major issue; for example I read in National Geographic a couple months ago about how, following the use of chemical fertilizers in Punjab, the chemicals contaminated the water
and people are developing cancer linked to this. It would also come with downloadable virtual textbooks to promote education, interactive apps, rather like the iphone, for kids, such as a virtual keyboard that they could use to learn to play and read music where they might not otherwise get the opportunity. They could also be used to communicate with tutors from around the globe, so perhaps they could learn English and other languages, and they could also be used as medical tools for diagnosis and treatment. It would come with two portable, wearable (as a wristband), electronic devices that could communicate with the main computer, that could be used for kids to communicate with their parents and for parents to track their kids in unsafe areas. A camera in it could learn to recognize the area. It would be solar powered, or perhaps, at night and in areas without ample sunlight, by some sort of thermoelectric converter of human warmth . Many of these ideas are already possible, but expensive. There is a mission called One Laptop per Child that wants to provide an affordable laptop to every school age child in developing countries to connect them to the rest of the world. I think technology is very important to connect people and create progress. Anyways, we had a long discussion about the implications of this massive explosion of technology. Though I think it will dramatically change our world, in a greater way than even like guns because there’s so much more technology and more powerful technology being developed now, I think that humans are essentially good. I think in general technology is developed and used for want to change the world for the better. There are a lot of science fiction movies that scare us with depictions of a future where humanity is lost and everything is computer-like, and of a future where we war with the machines we created, but hopefully such things will never happen.
