How to Restore Lost Power To An Old Engine

Engines are said, as a rule of thumb, to lose one horsepower for every year of age. So for all of you guys with older trucks, here are a few tips to increase your horsepower back toward factory specs.

Another tip I learned recently from fellow overlander and experiential marketing expert Matthew Mangus (@mangai_rollin): a mass air flow sensor cleaner like this can improve mileage and horsepower by cleaning the wires of the mass air flow sensor. This provides the car’s ecu more accurate data as it determines engine’s the best fuel/air mixture.

How to Route-Optimize a Map Using RouteXL

Firelookout Route

Last week I posted about the quickest route to visit all 47 U.S. National Parks. If you’d like to optimize your own routes, there’s a website called RouteXL that will help you do it. If your route has 20 stops or less, it’s free.

For example, if you wanted to leave Portland, Oregon, and spend a night in all of the states old fire lookouts, this would be the quickest route. Click map above (click it for a live version).

To create your own route, add locations in the field at the top-left of the page and then click the Find Route button at the bottom-left corner of the page. You can then use the Download button at the bottom-left of the page to share the route, download it in any number of formats, or open it in Google Maps.

If you’d like to camp in an old fire lookout, here’s a link to all of the available sites in the western United States.

In Rwanda Medical Supplies Now Delivered by Drone

In Rwanda, known as the “Land of a Thousand Hills,” trips to rural villages can take four hours by truck (in the dry season).  In that terrain, delivering lifesaving medical supplies was often an impossibility. Now though, a Bay Area company named Zipline, working in conjunction with the Rwandan government, has introduced a fleet drones that make the trip in about 15 minutes. The drones fly about 60 mph, circle their target, and deliver their cargo by parachute (with an accuracy of a few parking spaces). Well done!
