content: https://www.indiegogo.com/projects/izeee-touch-chargerIt's a sticker you put at the back of the phone that will harness the energy from your taps on the screen. By some obscure reason it is NFC-enabled as well.Yea right, give your phone a full charge but touching it every other second for 3 hours... Maybe if I hit it with a hammer for three hours, but I don't think the phone itself would like that. :-)Q: How much will this device charge my iPhone 6?A: If your phone will be off, but there will be some mechanic effects under iZeee, with middle frequency about 30-35 touches / per minute (it’s the same frequency when you type a message) your phone will charge your full battery in 3:35 hours.

content: An iPhone 6 has a 7 Wh battery (just as an example), which contains 25.2kJ of energy. 3.5 hours at 35 taps a minute is 7525 taps. That means they're saying this devices can capture on the order of 3-4 joules per tap? Seriously?

Everything that is needed to make a real product. Estimated national and international shipping date is December 2015."They are asking for $1000 in funding to cover 10 month's worth of engineering, software (?!) and manufacturing for a product that claims to deliver ~2 watts of power out of small vibrations. Riiiight."Contributors on this level can receive up to 4 discounts via our referral Thank you Program and get your iZeee for FREE."It's not just a scam, it's an entire multi-level marketing scheme!

content: 100% scam.Flexible funding, no technical details whatsoever, many variants of specs, CG generated images, etc.If you want to loose your money, this is your chance.

content: So, ignoring the technical aspects around the amount of energy available from a given tap, how does the NFC version transfer that power? Also, will it give continuous power from an internal cell, or will it just pulse the charger output? My phone wakes up as soon as the charger is plugged in - I think that 10 seconds of lit screen & running CPU will use far more than the tapping provides...

content: Quote from: mojo-chan on February 19, 2015, 04:15:23 pmFlaw? I call it an advantage in this case. When people start asking why the phone is not charging, they can say that charging is "not visible", but one can "feel" improved battery life. But that is assuming they will deliver anything at all...

content: Maybe they're using stacked layers on flex to act as a capacitor and a couple piezo layers to generate the electricity ?But seeing all those "traces" on the back of the unit i can tell this whole thing is BS.

content: Seriously wouldn't be surprised if we see a "crowdfunding crash", in much the same way as Atari crashed the 1980s video game market by releasing overhyped but generally rubbish games. Too many pissed off backers being vocal enough... which is a shame because there are legitimate hardware projects out there, but the scammers seem to outweigh them, at least per $ raised. IGG needs to do something about this before it damages their reputation irreparably.

content: Quote from: mojo-chan on February 20, 2015, 10:44:05 amYeah...I've submitted claims about numerous projects that were obvious scams, and neither Kickstarter or IGG have ever done anything about them. They just let the project continue, and several months later lo and behold it turns out to be a scam. At least they got their cut, right?

content: Hey guys,I just came upon the iZeee and thought that was an amazing way of technology. Although it is hard to say if it is a scam. The only thing out with NFC technology is a product such as the iQi. Here is an example of a demo of that:http://www.fonesalesman.com/products/iqi-mobile.You do notice that it does need a transmitting base to activate the receiver. So for the iZeee, that seems like a receiver but pushing you finger is considered the transmitter? Unless you can output at your fingertips at least 5volts and .005mA. Just a heads up for your guys of current technology, but if the iZeee does what is states it can, then this can change the charging industry.

It's the equivalent of holding a pair of phone books in your hands and then flapping your arms to fly. It's never, ever going to work. There isn't NEARLY enough energy in a finger tap to make even the SLIGHTEST difference in the battery energy level.

They never do anything. Don't even waste your time. The only way to fight this is to find a way to communicate with backers to convince them to pull out of a campaign before it's too late, and do your best to write reviews that somehow rise above the paid media syndicate.
