Minecart with Furnace

Minecarts with Furnace (also called Powered Minecarts) are a special type of minecart which accepts coal or charcoal as fuel for powered movement and can be used to push other minecarts, thus functioning as an engine.

Crafting
A Minecart with Furnace is crafted from a Furnace and a Minecart, as shown below:

History
The Powered Minecart (original name) was added in the 1.0.14 Seecret Friday Update 7.

As of 1.0.0, each piece of coal powers a Minecart with Furnace for 3 minutes. Adding another piece of coal at any time increases the total range by another 3 minutes. Previously, any fuel added before the Minecart stopped moving was wasted, as the duration would max out at three minutes regardless of how much coal was added.

As of 1.0.0, Minecarts with Furnaces on a level track will cover 200 meters per minute.

Usage
A good usage for the "Powered Minecart" Is to put it on the back on another minecart, so it's more like a train. A more important use of this is Rail movement in the Superflat world type on Survival Mode. Redstone is not obtainable to create Powered Rails, yet enough resources can be collected to create "Powered Minecarts".

To use the Minecart with Furnace, first place it on a track. Select your fuel (currently only Coal and Charcoal work) then use the "Use" control (normally right-click) on the Minecart. When right-clicking on the Minecart, you want to face the direction you want it to travel. You can make the cart change direction by right-clicking the Minecart while facing the opposite direction of travel. Your coal will be consumed once used on the furnace.

A Minecart with Furnace can push other carts at 3.4m/s. 1 coal or charcoal will cause the Minecart to run for 3 minutes or travel 612m.

Behavior

 * Breaking a Minecart with Furnace gives a plain cart and the furnace back (but any fuel inside will be lost).
 * Minecarts with Furnace cannot push other carts around 180-degree hairpin turns.
 * A player in a cart adds significant weight, requiring more power to push.
 * 1/1 slopes are too steep for a single Minecart with Furnace to push a single occupied cart uphill. 1/2 slopes (one flat-rail between each up-ramp) will allow you to push your train upwards, as it appears the Minecarts with Furnace have force applied in intervals.
 * Multiple Minecarts with Furnace yield more pushing power; 2 powered minecarts can push a player-occupied minecart up a 1/1 slope. (although very slowly). Three powered minecarts can push an occupied minecart up such a slope a very little bit faster but adding more powered carts doesn't have much effect on the speed.
 * A single Minecart with Furnace can push an occupied minecart up a 1/1 slope if there are additional minecarts being pushed (possibly due to bumping physics).
 * When a powered minecart runs out of fuel, it does not brake.
 * If too much stress is put on the Minecart with Furnace then it will stop. Right-click activates it again.
 * Each piece of coal powers a Minecart with Furnace for 3 minutes. Adding another piece of coal at any time increases the total range by another 3 minutes.
 * Minecarts with Furnaces on a level track will cover 200 meters per minute (about 3.33 m/s), or 600 meters per piece of coal. Pushing multiple Minecarts may decrease the range slightly, depending on collisions.

Trivia

 * Right clicking will cause the Powered Minecart to go forward a little bit, even if it is not loaded with fuel.

Bugs

 * As of Beta 1.8.1, Powered Minecarts do not produce the new lighting.
 * The orientation of the minecart and its furnace depends on the track only. As a result, the furnace may reverse front-to-back as the cart goes through a turn, and it will do so repeatedly when moving along a diagonal track.
