I love technology; I also love Kickstarter and its huge collection of useful/inventive/creative projects. I myself have backed half a dozen projects in there (including OUYA). The problem is that due to its popularity, Kickstarter faces a bunch of confidence tricks' attacks (also called SCAMS). As a technology guy, I have listed below a bunch of projects (some of them cancelled, all of them unfunded) promising free energy.
Notice that I will not fully explain exactly why every project is a SCAM, but you can guess that yourself, base on a bit of physics. Of course you know that there is no way to break physics laws (so far), so none of these projects will see daylight anytime soon. have fun!.
1- Powerful Box: they state "We aim to bring you free electricity after the upfront cost and produce no co2". Here is the link to the actual project on Kickstarter: http://kck.st/1upAsbt
2- Magnetic Siphon Electric Generator: they state "My invention uses a series of magnets to lift and/or attract Ferrofluids and converts potential kinetic energy into electricity!". Here is the link to the actual project on Kickstarter: http://kck.st/1A9QL3O
3- HISCORE Engine Project*: they state "Environment protection technology.Help us build our new green engine prototype to reverse CO2 vehicle emissions pollution on our planet". Here is the link to the actual project on Kickstarter: http://kck.st/1tRj03F *this one was suspended by Kickstarter
4- iPOWER by design: they state "A remarkable new way to produce energy. By backing this campaign you will part of a Globe change that our World desperately needs". Here is the link to the actual project on Kickstarter: http://kck.st/1wOlEcS
And the Bonus one:
5- Time Machine*: they state "Help me make a time machine, so that we can make this world a better place. If you could go back, would you save her? Humble words". Here is the link to the actual project on Kickstarter: http://kck.st/1lRh3fh . *No comments on this one!.
