The problem is that Kickstarter allows projects that are very obviously doomed to failure and doesn't act when it is pointed out. They should protect naÃve investors.
There was one recently for an AA battery that can be recharged in 30 seconds. It's basically a capacitor and regulator. People pointed out that at the $20 price point he set for one he couldn't buy any available capacitor that meet his claim of 1100mAh. Worse, he would need to charge at over 150A to get the time down to 30 seconds.
He flapped around, eventually found some surplus 150A power supplies and intends to ship them with the batteries for $20. Some people will probably burn their houses down since he can't possibly afford a descent connector.
People pointed all this out and Kickstarter did nothing. Other projects defy the known laws of physics, or don't even make sense (did you see the "internet battery"?)
Even eBay tries harder to shut down scams and sellers who are clueless.
