School Bus Solution


The Very Real School Bus Problem

The nation's 480,000 school buses are for the most part outmoded. Electric does not appear to be the solution.

  • The initial cost of $375,000 for an electric school bus is double the cost of a traditional diesel bus

  • Charging stations represent both a logistical and financial problem

  • Limited drive range of electric buses is a major concern--especially for transporting sports and music programs 

  • Weather is a complicating factor. Typical electric buses can only drive about 140 miles before running out of battery power--far less than a traditional bus. That range can be even less in cold weather

  • With electric there is the ever-present specter of culture-war politics--a confrontation that most school districts don't want nor have the bandwidth for

Government and School Districts Want a Solution


ZES new pending patents address the issues that electric school buses can't.

  • The capital costs to retrofit an existing bus is 15% of the cost of a new electric school bus

  • The ZES patented system can be installed on a most of the country's nearly half million school buses

  • The retrofit process takes less than 1 week

  • Range and power are commanded by the driver not the limitations of electric engineering

  • Long-term fuel costs for school districts are dramatically reduced  

  • Planet-warming emissions are greatly reduced especially at idle and low speeds when most emissions are produced

  • The ultimate result--cleaner air for school children

Note: The EPA has earmarked $5,000,000,000 for grants and rebates to solve the school bus problem. It thought electric buses would be the answer. That has not been the case. Quite the contrary.
