Solar Power Without Solar Cells? | EarthTechling

Solar Power Without Solar Cells? | EarthTechling: "The report explains that light has both electric and magnetic components but, until now, scientists believed the magnetic field effects were weak enough that they could be ignored. Rand and his fellow researchers, however, found that at the right intensity, when light is traveling through a material that does not conduct electricity, the light field can generate magnetic effects that are 100 million times stronger than thought possible. Under these circumstances, says Rand, the magnetic fields become similar in strength to a strong electric effect."

Making Millions

Chris Paine on facebook: "Email of the Day: "There is no one in this country who got rich on his own. You built a factory out there—good for you! But remember, you moved your goods to market on the roads the rest of us paid for and other generations built. You hired workers we all paid to educate.

Your factory was safe because of police and fire forces that the rest of us paid for. You didn’t worry that maurauding bands would seize everything and hire someone to protect against this.

You built a factory or an idea and it turned into something terrific—God bless. Keep a big hunk of it. But part of the underlying social contract is you take a hunk of that and pay forward for the next kid who comes along."

Why lithium-ion batteries die so young — Cleantech News and Analysis

Why lithium-ion batteries die so young — Cleantech News and Analysis: "When ions are removed, sent over to the anode and then inserted back into the cathode, we ideally want them to return to the same spot, in order to preserve that nice stable crystal structure.

The problem is that the crystal structure can change with each charge and discharge."

My Nissan Leaf Forum • View topic - Which is worse for the battery? 3 charging scenarios: "Trying to leave the car near 50% SOC when parked as much as possible.
Trying to charge up to only 80% just before I need to start driving.
Getting back on charge as soon as possible if I get down near 2 bars left.
Use opportunistic charging when taking side trips that threaten to upset the above routine.

Tesla Roadster Battery Care

Tesla Roadster Battery Care: "Think of battery degradation this way. It is very much a function of time spent at voltage and temperature. For instance, you do not want to charge a car all the way in performance mode, and then let it sit in the sun all day. Between the higher thermal limits and the high SOC, you are causing the battery a relatively high amount of degradation .In fact, the car will eventually allow itself to discharge to Standard levels if left in Performance mode to prevent inadvertent damage to the battery. If you start driving right away after charging in Performance or Range Mode, and don’t let it sit, you would minimize the damage incurred, as the time spent at these extremes is an important part of the calculation."

My Nissan Leaf Forum • View topic - Joining the 80% Club: "The numbers I used in the post you quoted were based on a JPL report for the Mars rover mission. They found the capacity fade from cycling to be about six times higher at 60% DOD when compared to 30% DOD. They used SAFT LiNiO2 cells with graphite anode and cylindrical stainless steel hardware. The cells were tested in 30% DOD regime (5000 cycles) with average energy fade rate at 4.0V at 0.000704% per cycle and 60% DOD regime (500 cycles) with average energy fade rate at 4.0V at 0.00430% per cycle.

I also found the Tesla battery care guide from Dan Myggen to be of interest. I believe that the Roadster is using 18650 form-factor LiCoO2 cells. I don't claim to be the world's foremost expert on lithium ion cells, but this is an important topic and I would love to continue the discussion. I'm not sure if this is the right venue though, this thread is already 24 pages long."

What happened to the safety issues with lithium-ion batteries? - Accelerated trends of the adoption of Li-ion batteries for electric vehicles | E2A - ELECTRO-TO-AUTO FORUM: " In case of overcharging, an excessive level of lithium ions is pulled out and this leads to the collapse of the crystal structure of the cathode material, during which the cathode develops exothermic reaction."

What happened to the safety issues with lithium-ion batteries? - Accelerated trends of the adoption of Li-ion batteries for electric vehicles | E2A - ELECTRO-TO-AUTO FORUM: "The manganese system employs lithium manganese oxide (LiMn2O4). The crystal structure of it is called the spinel structure, in which the manganese atoms and lithium atoms are located in the gaps between oxygen atoms. Due to such structure, the crystal structure remains stable when lithium ions are extracted in charging. "
