A kilogram of bread is about 2000 calories, about 9 kJ. Your body “burns” food too - probably more efficiently than you could make a steam engine for the same, but it’s about that much.
Energy from gravity is equal to mass * gravity acceleration * height. 1 kg of bread in a 9.81 m/s/s field has the same gravitational potential at “about a kilometer”.
If you’re throwing magic stake baguettes off the top of the Burj Khalifa, the energy would be about equal.
First drop then burn. You’re back to carbon but you double the efficiency (might not be double I’m not a psychic)
