It sounds like a dream to the teen in your house as he or she no longer needs to spend time mowing the lawn on your behalf, but apparently the EcoMow Lawnmower is currently being developed and has already generated a fair amount of interest from potential consumers. There is a downside to it all though – chances are it would be more suitable to large-scale applications rather than for the average home. The EcoMow concept is being worked upon by a startup lead by a team of engineers as well as business students from George Mason University. As for the biomass pellets that it generates, it could be a potential game changer if more and more devices or industries would adopt this as the fuel to run on. [Product Page]
