The fusor, is an apparatus designed to create nuclear fusion. Unlike most controlled fusion systems, which slowly heat a magnetically confined plasma, the fusor injects high energy ions directly into a reaction chamber, thereby avoiding a considerable amount of complexity. The approach is known as inertial electrostatic confinement (IEC).
Regardless of its possible use as an energy source, the fusor has already been demonstrated as a viable neutron source. Fluxes are not as high as can be obtained from nuclear reactor or particle accelerator sources, but are sufficient for many uses.
We’ve entered what some scientists are calling the Anthropocene — a new geologic epoch in which human activity, more than any other force, steers change on the planet. Just as we’re now causing the vast majority of extinctions, the vast majority of endangered species will only survive if we keep actively rigging the world around them in their favor. … We are gardening the wilderness. The line between conservation and domestication has blurred.
Berkowski made the first solar eclipse photograph on July 28, 1851, also using the daguerrotype process, at the Royal Observatory in Königsberg, Prussia (now Kalinigrad in Russia). Berkowski, a local daguerrotypist whose first name was never published, observed at the Royal Observatory. A small 6-cm refracting telescope was attached to the 15.8-cm Fraunhofer heliometer and a 84-second exposure was taken shortly after the beginning of totality.
