This RC lawnmower is a hybrid too

Now this the kind of competition we like to see, resulting in technology that's truly useful--like lawnmowers.

First we saw the "Lawnbott," then the "Auto Mower," and now we have the "GOAT" from Evatech. This mowing monster is strong enough "to pull a fertilizer spreader, climb 45-degree inclines, or even operate as a snowplow," Gizmag says.

But what truly distinguishes the GOAT--which stands for "Go All Terrain"--is its power source: a hybrid motor that runs on both gasoline and electricity. (We also like the remote, which looks just like the kind we use on the RC cars at RadioShack.) If all this still doesn't provide enough grass-wasting power for you, don't despair. Evatech has an even bigger model with tank treads for a mere $11,999.
