Obama, shown below, steps into the latest US technology on his summer vacation.

The $90 million prototype features a 4 foot high translucent screen that surrounds the cart which is equipped with a silent electric motor.  Many tiny cameras, strategically placed around the cart, project the scenery to the opposite side to make the cart invisible.

Press Secretary, Jay Carney, said, “The stealth features of the cart and its mobility are better than a Harry Potter invisibility cloak.”

The President was enjoying his vacation and the new invention until a golfer did not see the cart and blasted a tee shot into one of the screens.  That prompted Obama to quip, “We’ll have to work on bullet proof screens next.”  The President’s comment resulted in a 10% jump in the futures price of bullet proof commodities.

Rumors are circling that Halliburton wants to purchase 100 of the stealth carts for their petroleum engineers in Iraq even though nobody has seen a petroleum engineer in Iraq in 3 years.
