A, you should have to help yourself. If you have good valid point, speak it. If not, don't.
B, I was under the impression from previous information that the batteries used were nickel-cadmium. If in fact the batteries are nickel metal hydride, then I am wrong, and I question whether this is a step up or step down. NiMH has a high self-discharge rate, and is more prone to overcharge damage. (which also would make converting to a plug-in hybrid very unhealth for the battery. Likely why Toyota doesn't support plug-in mods)
C, My point about Lead Acid is thus: In a regular batter, the acid when discharged completely, is turned to water. Meanwhile, the lead can easily be melted down and reused. Cadmium, and in some cases the Nickel, is rendered completely un-reuseable. It must be discarded. As to this, I am unsure of NiMH at this time, so I'll not comment further. But be assured I will look into it.
With that said, let make this clear. I realize it's difficult to decern a persons manor through typed text, but I can promise you there is no ridicule. For me, it is simple. Something is either correct, or incorrect. Right or wrong. If it is correct, I am for it. If it is not correct, I am against it. If I think something is wrong, when it is in fact right, someone will let me know, and I will change to reflect the new information. (provided I verify it is right)
To me, that page seemed like big business promotional material (still does) because it didn't seem to conform to other information I had. Thus I deemed it to be wrong.
Normaly I try to not to sink into pure satire, but it does happen. Like someone who mentioned that there's enough hydrogen in 1 sq/Km of water to run the world for 7 years. For me to go through why that's neat but impossible, I'd have to do a college grade physics course. Since no one will pay me for that, I did a short satire post while trying to hint at pratical issue with it. I can only hope someone learned something from it.
