Some intelligent forward thinking researchers over at Hitachi, Xanavi, and Nissan have collected some data on ecological green routing that claims a 9% fuel cost savings on a test route. This technology is still in its infancy, but this is a perfect example of where a car computer can be used to accelerate development and deployment of technology. Implementing ecorouting will require Intense processing on the client or cloud for the complicated routing algorithms that factor in all the newly available data points:

Traffic & Flow speeds

Elevation changes and altitude

Road quality (smooth vs. rough)

Wind (eventually)

The cloud or development computer can also be used to coach the driver into more efficient acceleration and braking techniques which a lot of hyper milers are already using.

Eventually I imagine this type of data would help local governments prioritize road resurfacings and traffic control timings to help their citizenry become greener.

It seems like one of the key pieces to making this work would be accurate elevation Data. The paper I mentioned above used 50m resolution data from the government. One of the key data providers for elevation data seems to be intermap with 5m horizontal resolution and +/1 1m vertical. Check out their comparison chart to NASA data.

Goce from mp3Car will walk you through the steps necessary to power your laptop using unregulated ~6~24 volts with only the p2140 and the wire your laptop power adapter came with.



-For this project you need the following materials:
-p2140 and 8pin molex output harness
-Wire strippers 14-22 gauge
-Bench battery
-Multimeter
-Shrink tubing and heat shrink tubing gun OR electrical tape
-Solder gun and non leaded solder
-laptop and its power brick
-knife or scissors

To finalize this project you should do a continuity test on the stripped wire to find out which is positive and which is negative. Then you can twist and solder the p2140 output wires to the cut laptop brick wires. Turn it on to test it one more time, and then plug it into your laptop to test.
