just a point ( nothing to do with Trexa )what dangers are there when an electric car has a bad smash ?......... danger to the occupants and/or rescue workers, sorry for my lack of knowledge

@robinyatesuk2003: I think you should be more specific and ask the question of what dangers are there when a lithium ion electric car has a bad smash. My understanding (which is very limited) is that lithium ion batteries have higher risk of fire or explosion due to overheating from charging or shorts within the battery. In a high speed collision, one could certainly question whether the important bits of the battery stay in place. However, crashing at any speed is dangerous, and at what levels does the presence of a battery decrease your odds for survival is another good question. Good article(s) on the subject here:http://www.technologyreview.com/Energy/18762/?a=f
I think this (TREXA..shouldn\'t it be Trexa) idea is cool, we readers should have a forum on what would a car look like if it weren\'t influenced by the presence of an engine and drivetrain. Certain elements of a car are functional and are incorporated stylishly by automotive designers. If those elements are no longer needed what would we get?
On the other hand, there is a lot that goes into vehicle safety here in the US. It would almost make sense to include the occupant cabin and rollover protection as part of the base Trexa in hopes of not needing separate crash tests for each vehicle design.
Final thought, when will this be open source? I would love to design something for this. I\'ve forwarded my question to TREXA... will post the response here.

cool information at everyday !!!

Make the battery systems swappable for any battery that has the same universal type of plugin component (like Better Places idea) not proprietary. Only when computers makers made like motherboards and power supplies and USB universal did it work. I hope it has that-great idea.

good design this should be at the museum

Hmm.. Looks like they ripped off GM\'s Hywire concept.

...and here we are 10 months later and these \'trexa\' people have fallen off the face off the earth. What a surprise.

Yeah, no doubt they were \"removed\" by the big three. After-all, can\'t have any serious competition from a game changing product when the American Auto Industry is at stake. Look at the Subway systems in California. Automakers bought out the companies so they could squash the competition to their massive roadways to be filled with their cars.

FYI 'romegakahn': It was not "Subway systems in California" but the trolley systems that were bought up by a front corporation made up of automobile manufacturer's agents. There was a conspiracy trial and the defendant auto-mfg front corporation lost (one of very few conspiracy trials ever in which the conspiracy was found to be "true"). Alas, the trolley systems could not be re-created and, as we all know, the auto manufacturers ended up "winning."

It's amazing how similar the chassis is to modern AFX and similar slot cars. We got it right way back in the 1960's!
