While lithium ion batteries are common in today’s consumer electronics, they require inbuilt safety mechanisms that can affect efficiency; as well, lithium batteries tend to fail after a few years. The Murdoch University researchers say the main challenge they faced in developing a sodium-ion battery was finding cathode and anode materials capable of accommodating sodium’s ionic size – which is 2.5 times larger than that of lithium. After testing various metals and phosphates, Dr Minakshi’s team eventually found success with manganese dioxide as the cathode and a novel olivine sodium phosphate as the anode. The result is a safe, cost-effective battery with high energy density. follow link to read the restnondisclosed_email@example.com (TheLivingShadow)Mon, 03 Sep 2012 21:57:57 +0000 lead-acid batteryhttps://b2012overleven.runboard.com/p2445,from=rss#post2445https://b2012overleven.runboard.com/p2445,from=rss#post2445 nondisclosed_email@example.com (TheLivingShadow)Tue, 03 Jul 2012 16:24:08 +0000 copper, Mg, carbon, zinc batterieshttps://b2012overleven.runboard.com/p1985,from=rss#post1985https://b2012overleven.runboard.com/p1985,from=rss#post1985try magnesium powder from ebay, carbon powder from batteries, smash the carbon rods till its powdery, mixed both of them and put copper and zinc as electrodes..

Now, not being an expert in these things, the only options that I can think of are: * Batteries * Capacitors Both of these options are expensive and it is not very feasible to be carrying big heavy batteries into our remote location. ---------------------------------------------------------- as the stream runs along the valley floor, it often goes through very deep chasms ending in waterfalls [small ones, but significant]. Because of this, there are many options for utilizing one of these bottlenecks for creating a dam; once the water pressure can build up and get harnessed by some hydro dynamo technology, real time energy should be a real possibility. As well, what i've learned about wind energy (some years back), the output of a propellor-fueled dynamo is enough for running many appliances. It's not at all like the drip drip amounts that solar panels give off. Hydro and wind together should make much storage of energy moot and there's loads and loads of it on location. Batteries are expensive, heavy, and need relative frequent replacement. A system that only uses them as backup would be preferable, i think, but i'm not technical and wouldn't know how to set it up myself. -------------------------------------------------------- Here are a few things we can do on a small scale using hand crank technology.

One wraps iron/aluminum and copper wire around an iron rod and somehow it produces a current and an elektromagnetic field when it's moist. Apparently it needs to be put in the ground at some point. Seems like it would at least be good enough for some perpetual lighting purposes.nondisclosed_email@example.com (TheLivingShadow)Tue, 14 Feb 2012 19:19:41 +0000 ultra capacitorshttps://b2012overleven.runboard.com/p957,from=rss#post957https://b2012overleven.runboard.com/p957,from=rss#post957Traditionally quick and powerful but energy poor, capacitors have transmuted into quick, powerful, and energy-rich storage devices whose first applications are likely to be in hybrid electric vehicles and backup power supplies. Known for storing a short-lived jolt of electricity essential to the successful operation of electrical circuits in devices and appliances ranging from PCs to microwave ovens, cell phones, and televisions, the capacitor is in the midst of a major, ongoing upgrade of its energy storage capabilities. After nearly two centuries in which batteries have been the obvious choice for storing usable amounts of energy, high-end capacitors, known as ultracapacitors, are poised to challenge them in a growing range of applications.          "In fuel cell vehicles, ultracapacitors have demonstrated a higher recovery of energy from braking than batteries, are considerably lighter, have a longer economic life, and are more environmentally friendly in their manufacture and disposal," says Pierre Rivard, president and CEO of Hydrogenics of Mississauga, Ontario, a clean power generation company with a focus on fuel cells.          Looking beyond applications in cars, he continues, "When paired with fuel cells in stop-and-go mobility applications, such as forklifts, ultracapacitors provide burst power for lifting and acceleration and enable regenerative braking; in backup power applications [ranging from hospitals to office buildings, factories, and homes], they provide instantly available short-term bridge power. In many applications they buffer power demand peaks, allowing our scalable fuel cell systems to be optimized for size and low cost." read morenondisclosed_email@example.com (TheLivingShadow)Tue, 11 Oct 2011 10:08:53 +0000 portable earth batteryhttps://b2012overleven.runboard.com/p948,from=rss#post948https://b2012overleven.runboard.com/p948,from=rss#post948copper and magnesium strips in earth = energy YouTube vid This YouTube vid covers how the magnesium-carbon air battery works. Apparently one buries it in the ground at some point, just like the Stubblefield Coil. Very interesting vid. Make a homemade “Earth Battery” that powers watches,clocks,calculators - copper wire - several small bolts (screws or nails; use “galvanized”) - ice cube tray - moist dirt/soil. (dirt will “dry out”; just add 1 or 2 teaspoons of water to each “cell” and the battery will be “recharged”) For increased voltage make more than one and connect with each other. youtubenondisclosed_email@example.com (TheLivingShadow)Sun, 09 Oct 2011 09:30:27 +0000 storage [batteries, capacitors, etc.]https://b2012overleven.runboard.com/p849,from=rss#post849https://b2012overleven.runboard.com/p849,from=rss#post849Earth Battery Ultracapacitors: batteries are so 20 years ago...
