The traditional solar updraft tower has a power conversion rate considerably lower than many other designs in the (high temperature) group of collectors. The low conversion rate is balanced to some extent by the lower cost per square metre of solar collection. Model calculations estimate that a 100 MW plant would require a 1,000 m tower and a greenhouse of 20 square kilometres (7.7 sq mi). A 200 MW tower of the same height would req.
[pdf] There are eight known planets orbiting our sun, including Earth. Making a model is a fun introduction to this solar system, and a good art project for primary school science classes. This detailed example can take a few hours to make, but most of that involves waiting for paint or clay to dry.
