The thing is, this waterlily actually does work about as good as you could expect something this size to work, the problem is that it doesn't do enough. The storage capacity of say, your iphone's battery at ~3,000 mAh is barely budged with the piddly output of the waterlily. It will eventually charge a phone battery given enough time but that time is impractical.


It's easy to understand the principals at work here, turbine generates electricity, make it small and compact and you can charge your phone on the go. It's easy to trick yourself into thinking this should or could work. The problem is the vast difference in scale of what a portable turbine can do compared to the incredibly power dense batteries we carry around. So it really isn't very close.


Even the hand crank on this thing is useless because the turbine is geared to move at even a light breeze, which means your cranking doesn't require much force, which mean not very much work is being captured which means you have to crank it a million times to get anything useful out of it.


For an idea of what is realistic,check out a hand crank like this. You strap it to a tree and crank the thing which has a fair bit of resistance at a pace of about 80-90 rpms consistently for a half hour and you can maybe expect 10-15% of your phone's battery to charge off of that.

i think a better alternative would be these 'fish tanks' none of them are actually big enough for a fish to live in without eternal suffering, but they look like theyd make a cute lil plant holder

That Rotablade Pendulum actually looks exactly like the one I actually have. Here's the Amazon page I ordered from... looks like it was a cheap Chinese knock-off. Thanks for the direction!

I bought this years ago from ThinkGeek, but don’t see it anymore on their site. It doesn’t make a very good coffee cup but I like using it on my desk to hold my office knick knacks.

But Amazon has it now!

Sorry, I'm late to the party but I have this kit and it's not the one you see, but I got it for my mom and she loves it.

The "folks who created the contraption" appear to be so smart they're out of business. Google search turns up very little, but I did find one seller on eBay that has ten of them. He wants $1,588 or best offer for them.

No wonder these guys geniused out of the market. Here's one that uses mild adhesive to do much the same thing. It sells for under $100 and you don't have to find a 220V European outlet to plug it in.

There's a black on on Amazon for $15. It's not "contractor grad", but it's probably ok. Same brand. The red one is on Amazon, as well.

$10 on Amazon. 3/5 stars (47 reviews) with 38% being 5 star reviews and 37% being 1 star.


Most common complaints: too tight, product breaks/tears, does not make you swim faster.

I've used products similar to these and they absolutely help you swim faster, assuming you're swimming freestyle and have the upper body strength to pull the added resistance. These ones however are sized for children and will likely become trash shortly after the first use.

These are the ones that I got but it looks like there are different ones also on amazon.

For those looking.

This looks great, so I looked up some reviews. There may be some issues after only a short while pertaining to leakage, cleaning out properly to prevent mold and it breaking after heavy usage.

It has wireless charging.

$220 not to bad!

Same Concept, $15

I use it at least once every fall for a bushel of apples and it’s wonderful.

why not a hand held wire cutter like this: https://www.amazon.com/Westmark-Germany-Stainless-Cheese-Adjustable/dp/B000VJ81QK/ usually much easier then a knife (less effort required and more even slice)

I own one of that design. It would be much better without the top flat, which gets in the way and fails to make the holder any more aesthetically pleasing. It's not as if it hides the fact you have toilet paper there, and the flap serves no functional purpose.

It's otherwise nice, a cinch to replace a roll. $14 on Amazon.

It is a epoxy resin and he added color:
