I just stumbled across something very cool. It should help with the discussion on emissions. I just loaded it up and haven't done much with it yet, but I thought I would pass it along. http://www.transportation.anl.gov/software/GREET/ |

I've posted this link before on other Edmunds chats but I think it belongs here. Electric cars with their batteries charged by nuclear power stations are the only way to go. The link describes safe nuclear generating plants. http://www.eskom.co.za/nuclear_energy/pebble_bed/pebble_bed.html

My objection to expanding nuclear energy has to do with the fact that we live in a world with terrorists and that's not going to change. Nuclear plants and their waste materials are going to be very attractive to these people that want to do us harm. The cost to provide security for these facilities will be considerable and will only increase as the threat becomes more sophisticated. I think from a domestic security perspective we are best off generating our electricity on the most local level possible. Homeowners producing their own electricity through wind, solar, etc., being tied together in a small community grid.

Coal mines and their environmental impact are more dangerous than nuclear power. Coal fired power stations pollute the atmosphere. How many coal miners have been killed in America and how many people have died due to nuclear accidents in this country? |

Replying to: snakeweasel (Aug 08, 2006 5:12 am) Fact of the matter is that solar power chargers do exist. Cell phone companies use them to charge their remote station batteries as one example. Solar panels are expensive to make and the manufacturing process is environmentaly dirty. It's also no good to plug into the solar charger at night. It's just not going to work! Bear in mind we are talking about millions of vehicle batteries that would have to be charged if and when a change to battery power took place. Super capacitors are an alternative to conventional batteries and at this moment you can buy super capacitor batteries for your flashlight. There are claims that they outperform standard rechargable flash light batteries and are much lighter. |

Replying to: snakeweasel (Aug 08, 2006 5:12 am) Its already being done. Tesla Motors website states that they have an arrangement with solar installers to provide customers with this capability. If you live in a sunny climate like the desert Southwest this could be a very attractive way to go especially when the tax breaks are considered. While I'm sure the initial investment won't be cheap this represents something the individual can do to make himself energy independent. Expanding nuclear energy may be a good idea but it is something clearly outside your control.

Replying to: tpe (Aug 08, 2006 5:55 am) Early on, Governor Arnold talked about a grand plan to put solar cells on all new houses. I haven't heard anything about that lately, so I don't know where it stands. Once PV cells get thin, and flexible (which the new ones are), and cheap, they make a lot of sense because they distribute the generation across the grid.

THANKS! Well, THAT'LL certainly 'clean up' the other discussion....

Replying to: prm2000 (Aug 08, 2006 6:34 am) Some of the current government subsidies for PV install are, IMO, somewhat misguided. The global demand for PV panels is far outstripping manufacturing capacity and these subsidies are only agravating the situation. The result is that over the last 2 years the cost per watt has actually increased. The positive side is that manufacturers are increasing capacity at a rapid pace but this might have occurred even with slightly lower subsidies. The comment that millions of EV owners charging their batteries is going to overtax the grid is unfounded. For one thing it will probably take at least 10 years for there to even be 1 million EVs on the road. Also, the people that operate our nation's electricity grid welcome these vehicles. I don't pretend to understand how this works but apparently it creates the potential for load levelling, which has a positive impact. Not to mention your vehicle can now be an emergency back-up power supply for your home.
