He had no part in the design mistakes that have now been largely surmounted, and that have been detailed in the many references he cites. One point of unique­ ness should have been added: This is the only place in the world where a significant number of large downtown office buildings are both heated and cooled by the energy from a very difficult fuel garbage, and it's encouraging to know that with municipal support equivalent to a tipping fee of approximately $8.00 per ton and the generous steam price of $6.00 per thousand pounds, this plant is paying its way while providing a clean method for waste processing. HistOrically it is a source of some amazement that the plant began operation with no tipping fee at all! The author is also rightly proud of his. plant as an achievement of American technology. However, that good pride must in this instance bear some blemish because it failed to utilize some vital European know-how. It was needless to start this plant up in 1974 without studs and silicon carbide protecting the lower furnace walls. Long experience in Europe had demonstrated that no high tempera­ ture steam-generating plant could operate for long
