Would you rather drive a biodiesel, hybrid, electric, or hydrogen car? - Page 3

The energy fields and EMF are two of the many things in life that can't totally proven to be untrue so some people accept them as fact. That no widely accepted scientific evidence can be offered in support of those theories doesn't deter the believers.

I spent my working years in process plants where all types of power and control systems were used and this was of no concern. In engineering you work with facts - not feelings.

I can remember the stories about HT power lines from 50 years back - like you pointed out there was no substance to it. 

When I was in India it seemed that if a traffic light went out in Bombay (Mumbai) the ISI (Pakistini spy agency) got blamed for it. No reason but that it was the boogey man. Kind of like railing against big oil, the auto companies etc in most cases.  

Yeah it's similar to the myth that cell phones cause brain tumors.  You'd have to do like a 30 year study to conclusively prove it's not true, but there's just no evidence to indicate the myth is true.  Same with EMFs.  So some people employ the precautionary principle (better safe than sorry).  But I think that's overkill.

A couple of days back I read an article on the number of new power stations required if there is a major switch to electric cars - very large number.

It is logical though that when we switch from one fuel to another that the change in infrastructure is also required.

Another point was the load that 'fast charging' would place on the grids. Again the numbers were very large.It would look like a smart grid would be required where if someone wants to fast charge their car in the day time the charge would be prohibitive while night time charging would be reasonable. 

The original battery was made by Panasonic, (EC-EV 1260). 15.28 L, 4.57 W, 6.89 H. (12 volt, 60 AH). The Silverado Hybrid battery is also made by Panasonic, GM part # 89021957, same dimensions and slightly different chemistry but will work. They are AGM/ VRLA. Attempts have been made to purchase directly from Panasonic, but the market just isn't large enough for them to deal with. (Only about 50 of these trucks left). The battery box holds 26 batteries. 14 on the bottom and 12 on the top. No other battery shares these dimensions or equals the performance and charging profiles. Every battery I have found that will actually fit in the box has at least one specification that does not allow it's use. Optimas looked good but the quality dropped to unacceptable when Johnson Controls bought them. Deka batteries looked like they would work but the specs say never exceed 14.7 volts when charging. The computer in the truck will occasionally charge to 16 volts to balance the pack. Fitting in the box is very important. It is a sealed container with all the batteries vented outside of the box. The charger runs the AC to cool the batteries while charging and monitors each battery for voltage. There is a battery control module in the box that controls everything. I could attach high voltage leads to the battery pack and charge with a separate charger, but that bypasses all of the safety built into the computer.

A plug-in hybrid is a more realistic and cost-effective option.
