Why don't we just launch nuclear waste into space?

Sending radioactive waste away sounds simple until 'away' needs an exact destination. A 1973 NASA study compared space-disposal routes and examined how packages might survive accidents, while acknowledging that a quantitative risk assessment still needed more work. Its historical proposal makes the transport problem concrete without supplying today's costs or launch risks.

  • How should a comparison separate the chance of an accident from its consequences?
  • Would a destination that permits retrieval be an advantage or a drawback?

How can a heat pump deliver more heat than its electricity input?

Energy4–5 minA heating device seems to promise something impossible when its heat output exceeds the electricity it uses. A heat pump's energy account includes another input: heat moved from its surroundings.

How does a photovoltaic cell turn light into electricity?

A solar cell can generate electricity without a turbine or other moving machinery. Light interacting with a semiconductor starts the process, but separating and collecting the resulting charges is what makes electrical output possible.

How does a wind turbine turn moving air into electricity?

Energy3–5 minA turbine's blades are only the visible beginning of the journey from wind to electricity. Their rotation drives a generator, though the machinery connecting those parts differs between turbine designs.
