The following is a paper by H. Aspden published in Proceedings of the International Symposium on New Energy, Denver, Colorado, USA (April 16-18; 1993) pp. 1-19.
Abstract: Although economists can estimate when known sources of energy will run out, they are not able to predict anything of comfort that can afford real hope for our energy future. Nor, indeed, are those engineers and scientists, who profess to understand energy matters, likely to foresee the real shape of things to come. Invention has been the driving force powering our industrial civilization so far and one simply cannot predict invention! Even so, the author, who combines a professional career patenting high energy technology inventions with a lifelong vocation devoted to the study of energy fundamentals, here argues that the needed solutions to our problems are already visible on the energy horizon. We do not need to gaze into a crystal ball. All that is needed is to direct our vision to focus on the truths which are now emerging from the work of those engaged in New Energy science.
