Hi anyone know if you can charge a MacBook via USB?

If not why not. What would they need to to do enable this? Obviously it would charge slower but for example my car has USB outputs to charge phone and GPS ... a passenger being able to charge or at least use the MacBook and not drain the battery would be cool.

No, because a computer is a host and not a peripheral. Peripherals receive power from hosts, not the other way around.

You can always go to Walgreens or RadioShack and buy the Cigarette Lighter AC Converter. It, obviously, plugs into your cigarette lighter and it has Regular Output plugs that you can just plug your MacBook's Power Cord too and you got a Car Charger

Hope that helps.

Cheers

I don't believe anyone besides Apple makes an adapter with a MagSafe end, since they have a patent on the design. This has been a common complaint since Apple's adapters are so expensive.

It would take about 15 years to charge a battery using the output from USB.

The lack of cheap adaptors is a pain - I'd love a separate power supply in the bedroom, but for £60 Apple can go swing.

I think the device he's talking about gives you an equivalent to a wall socket, so you can plug anything with a regular plug into it. Not a direct connector from the cigarette lighter to Macbook.
