In September, the UK’s University of Bath completed construction on a small building whose walls are insulated with the shredded woody inner core, or shiv, of the hemp plant (not to be confused with bast, the fibrous outer part under the bark).
The hemp plant, which can’t be grown in the United States because one variety, (more…)

Each year, we come across a new set of discussions on the subject of Moore’s Law – the idea that the potency of technology doubles every two years. Intel co-founder Gordon Moore observed that the number of transistors that could be put onto an integrated circuit doubled with that regularity — and that this exponential growth persisted for an astonishingly long period of (more…)

The image most people have in their minds when they think of wind turbines are the big, white horizontal-axis wind turbines with their massive blades spinning slowly on a wind-swept plain. But the clean energy revolution–if, in fact, it is a revolution–has room for more than just one design of wind turbine.
But vertical-axis wind turbines (VAWTs) are poised to (more…)
