Actually Tadiran has been making these cells for 30 years and makes many millions each year on totally automated equipment.
You can find Tadiran batteries in toll tags, such as the EZPASS, in automatic water, gas or electric meters, pressure sensors in tires, tracking devices, etc.
Sounds like custom-made, not mass-produced. That should be the case for consumer batteries, but I bet everyone here has opened up a flashlight long idle in the junk drawer that had goo oozing from the batteries, fouling the interior.
Aclara, a manufaturer of automated meter reading products, has its original units operating for over 25 years with Tadiran batteries, without replacements or recharging.
Energy harvesting systems have a lot of parts and thus reduce reliability. In addition they take up space and add cost. Aside from that, the source for the harvested energy may change over the years.
As for recycling them, possibly, but they are a such a small portion of the product stream that fixating on them would be a waste of time for all except troublemakers.
There are not that many applications that really need such a long life, and none of them include consumer products, for which the intended lifespan is six to ten months. Why put a long life battery in a device that will be in the landfill in less than a year?
Using the most low powered electronic devices is certainly a good choice insolving the problem from the other end.
1. They are expensive - maybe too expensive for a consumer product.
2. They suffer from passivation, so you have to keep them in a constant state of discharge - this limits their usefull life to less than a decade.
3. They have limited maximum current draw - a few tens of milliamps.
So they are fime for telemetry applications where the equipment spends most of it's time asleep, but it's a product suitable only for very specific uses.
Now we all know perpetual motion isn't possible. However, when you talk about batteries and the ability to capture energy that would otherwise be considered wasted. It just shows how much potential there is out there. Whether it be capturing the energy of a car as it slows down and generating energy with it, or capturing the energy while one walks I think the opportunities are just endless. And combining enery generation with the advancement of energy storage is just really exciting.
Using almost 200 light-emitting diodes in the front and back of the new 2014 CTS, Cadillac designers are showing how LEDs can change the character of a vehicle.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
