When it comes to eco-friendly forms of powered transportation, we generally tend to think of electric vehicles. Many people are still bothered by their limited range, however, along with the fact that it takes them a long time to recharge. That's why Los Angeles-based ProGo Recreation is taking another approach with its ProGo 3000 scooter – the thing runs on propane.

It can carry a load of up to 275 lb (125 kg) The planned retail price is $449 It has a 25-cc four-stroke engine The scooter features an easy-pull engine start
The ProGo (not the GoPro, that's something else) utilizes a standard 16.4-oz (465-g) propane cylinder, of the type used for camp stoves. Attached to the rear deck of the scooter in front of the 25-cc four-stroke engine, one of those cylinders reportedly gives the vehicle a range of 30 to 40 miles (48 to 64 km) or two to three hours. It has a top speed of 20 mph (32 km/h).
