Interesting ideas that can change the world should be talked about but more importantly shared. If you are interested in the different problems that are facing us and future generations. Then get involved. More importantly we need to just build it or just try it. Have a look at the different projects that have been tried and have your say on how things could be done better. Have a great idea or something that should be built write about it on the suggestions page. All of the projects should provide an easy way for you to see how a “Thing” is built so you can do it too.
