Cutting Lawns with Lasers?

       This paragraph is about cutting lawns with lasers.  According to Dick Ahstrom, there is someone that invented a laser lawn cutter.  He says that the laser lawn cutter helps the lawn grow.  It helps, because the laser lawn cutter only singes the top of the grass.  That helps the lawn grow better.  The laser lawn cutter also does not use fossil fuel, so it is better for the environment.  The laser lawn cutter still uses electricity, but it only needs about 1 watt to power the laser.
