(www.washingtonpost.com)
This is a most excellent place for technology news and articles.
I have my shopping list together to convert an old Kia Rio to electric for 100 km range, it's about 400lbs of lifepo batteries and a 200lb motor. So slightly more than the cratered ICE motor I'd be taking out.
But yah, if you want to drive across the country, convert an SUV or light pickup for the room to keep the batteries, and remove everything weight wise that you can to compensate.
