Reproduction for non-commercial purposes   Yes. It is OK to reproduce these cartoons and ideas in non-commercial websites and publications. I only ask that you use the contact link and inform me of the type of publication and your estimate of the circulation e.g. Classroom resource. Junior High School. 33.

There are two reasons for this. Firstly, it makes it possible to limit people from using the cartoons in ways that increase the learning blocks to understanding the wonderful nature of energy. Secondly it prevents people from using the cartoons for commercial gain without permission.

Note: is not the address of a company.

File size for printing.

My apologies if the cartoons do not reproduce well yet. I am experimenting with drawing formats and website facilities to enhance reproduction in multimedia. Thanks for your patience.
