Really? Drive-charge electric motor claims

What's your opinion? This article <Drive-charge electric motor will allow electric cars to travel farther than gasoline cars, without stopping to recharge and cost $0.00 | frenergy.ca – Free Renewable Energy> claims one can create an electric motor that is either (a) capable of recharging itself well enough to dramatically extend EV ranges, surpassing ICEs, or (b) a perpetual motion machine. The second claim is surely not true, since there are still inefficiencies that must gradually reduce the batteries' charge to, well, nothing, eventually, right? But is the first claim true? Could a set up like they are suggesting produce a vehicle with significantly greater range than an ICE? Seems implausible to me because I can't believe Toyota, Honda, GM, and Nissan and others would spend so much on battery technology and regenerative breaking R&D if they could just read this website and get better than the ranges promised by the Tesla roadster, the Leaf, or the Volt! I also know from deleting my alternator, that it wastes energy while producing electricity.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.

Could their system produce an electric vehicle with significantly extended range? No--not unless they are somehow capturing energy that would otherwise have been turned into motion or wasted as heat. And if they're simply attaching a pulley and generator to the electric motor, then that isn't the case.

But, I'm no electrician or physicist. Someone correct me if I'm wrong, but this has "law of conservation of energy" written all over it.

So long as the drive-charge ™ electric motor is running and the pulleys are turning the motor will keep on recharging the battery – perpetually. That being the case the drive-charge ™ electric motor can also accurately be called a perpetual motor – a machine that provides perpetual motion.
The motor will keep turning until the battery is dead, if you have a device like this your battery will go dead quicker and the device will stop working, yes it will recharge the battery but it will NOT recharge it as fast as it is drained.
