Below is a list of website ideas based on new technologies recently developed. If you're looking to create a new website, you might consider developing one of these ideas. Early bird gets the worm.

1. 3d Printing models - There's a new technology that's become popular in 2011 called 3D printing. 3D printing has actually been around for a while, but with the creation of the Cube, it's become affordable for consumers and hobbyists. The cube printer requires 3D models to print. It would be a great idea to create a website where users can create account and sell/trade their 3D models ideas designed for the Cube or 3D printing in general.
2. 3D Printing store - Unlike regular products, 3D printed products are very easy and quick to develop. Most products require time consuming patents, prototypes, and manufacturing setups, but 3D printing products can be sold days after the idea arises. Because 3D products evolve so quickly, it would be a great idea to have an online store specifically made for selling 3D products. Users could create accounts and sell their parts and products online.
3. Food Stamps Food Shop - A website where people can sell the food that they got with food stamps online. As irrational voters and liberal agendas produce more free food, why not trade it for money? Money lasts a lot longer than food and unsustainable aid systems.
4. Stem Cell Hair Regeneration - Starting a website and ranking it for this topic could prove a good investment based on new such technologies on the horizon. Here's an article: http://www.sciencedaily.com/releases/2012/04/120418095011.htm
5. Small Eco Homes Blog - The demands of a waning economy and advances in technology have given rise to eco-friendly cost affected homes or shelters like the Tetra Shed for example. Why not start blogging this? They should only get more popular over the years.
