With computers now so commonplace and such a big part of our business and personal lives, most Americans are all too familiar with hard drives crashing and/or Internet signals dying.

With this in mind - and given increasing needs to address environmental challenges - one Las Vegas company strives to offer comprehensive relief for both computers and the environment in the 21st century.

When there's a computer repair emergency at a local resident's home or their company, Chad Stone is dispatched to the rescue.

Even if people have few issues with viruses or security problems, often times they struggle with myriad simple (but nonetheless debilitating issues) like an inability to get online.

A computer repair technician by trade, Stone started his own business two years ago and called it PC 911. This unique company not only revives computers, but is helping to preserve the environment, as well.

How is PC 911 so environmentally friendly?

First and foremost, Stone makes his house calls in old ambulances that run on 100 percent used vegetable oil. That's a huge start.

In addition to a great marketing angle, the old ambulance gives him just the serviceability he sought for his computer repair store on wheels.

It comes with everything he needs, including cabinets and compartments for every tool and supply, such as parts and 10-12 boxes of wiring - and even has a stretcher to minimize the number of trips to and from the vehicle.

On a typical day, PC 911 responds to up to a dozen residential calls and up to 10 business calls for computer repair and network support.

It's always good to see a business thrive that also takes into account environmental impact, and sets a good example for these changing times.
