Zeolite – Uses

Commercial and domestic Zeolites are widely used as ion-exchange beds in domestic and commercial water purification, softening, and other applications. In chemistry, zeolites are used to separate molecules (only molecules of certain sizes and shapes can pass through), as traps for molecules so they can be analyzed. Zeolites have the potential of providing precise and [...]

HD 189733 b – Physical characteristics

Assuming the planet is tidally locked with its star, this suggests that powerful easterly winds moving at more than 9,600 kilometers per hour are responsible for redistributing the heat. NASA released a brightness map of the surface temperature of HD 189733 b; it is the first map ever published of an extra-solar planet. Water vapor [...]

Biomimicry – Examples

Researchers, for example, learn from and emulate termites’ ability to maintain virtually constant temperature and humidity in their Sub-Saharan Africa homes despite an outside temperature that varies from 3 °C to 42 °C (35 °F to 104 °F). Project [http://www.sandkings.co.uk/index.html TERMES] (Termite Emulation of Regulatory Mound Environments by Simulation) scanned a termite mound and created [...]

Al Gore and the environment – 2001 – present

Generation Investment Management In 2004, Gore co-launched Generation Investment Management, a company for which he serves as Chair. The company was “a new London fund management firm that plans to create environment-friendly portfolios. Generation Investment will manage assets of institutional investors, such as pension funds, foundations and endowments, as well as those of ‘high net [...]

Climate sensitivity – Introduction

Climate sensitivity is a measure of how responsive the temperature of the climate system is to a change in the radiative forcing. It is usually expressed as the temperature change associated with a doubling of the concentration of carbon dioxide in Earth’s atmosphere. The equilibrium climate sensitivity refers to the equilibrium change in global mean [...]

The Centurions (TV series) – Assault weapon systems

Each of the Centurions is specialized for a particular domain, originally land, sea or air/space. They all have multiple weapon systems that can be ‘charged’ to their exo-frames. As evidenced in the five-part ”Man or Machine” series of episodes, the exo-frames also serve as strength-amplifying exoskeletons. This explains how the Centurions can carry the full [...]

Burning Man – Criticism

Concerns regarding the “Leave No Trace” policy Burning Man takes place in the middle of a large playa and while not inhabited by humans itself, the area around the playa is home to many animals and plants. Supporters of Burning Man point out that participants are encouraged to leave no trace (LNT) of their visit [...]

Fermi paradox – Empirical resolution attempts

One obvious way to resolve the Fermi paradox would be to find conclusive evidence of extraterrestrial intelligence. Efforts to find such evidence have been made since 1960, and several are ongoing as of 2010. As human beings do not possess interstellar travel capability, such searches are being remotely carried out at great distances and rely [...]

Carbon nanotube – Potential applications

: ”See also, for last current applications: Timeline of carbon nanotubes” The strength and flexibility of carbon nanotubes makes them of potential use in controlling other nanoscale structures, which suggests they will have an important role in nanotechnology engineering. The highest tensile strength of an individual multi-walled carbon nanotube has been tested to be is [...]

Kingman Island – Recent development

Since 1999, a variety of proposals have been made for Kingman and Heritage islands, most focusing on retaining the islands’ character as one of the few remaining wild places within the city’s limits. In December 2000, D.C. Mayor Anthony A. Williams signed an agreement with the Department of the Interior allowing the District government to [...]

Global Energy and Water Cycle Experiment – Coordinated Energy and Water Cycle Observations Project

The Coordinated Energy and Water Cycle Observations Project (CEOP) is the largest of the panel projects. There are several regional project areas most of these are now covered by CEOP Areas For CEOP which survey the hydroclimate for southern African (AMMA), Baltic Sea area (BALTEX), North America (CPPA), Eastern Amazonia (LBA), La Plate Basin (LBB), [...]

In-situ resource utilization – Locations

Mars ISRU research for Mars is focussed primarily on providing rocket propellant for a return trip to Earth& — either for a manned or a sample return mission& — or for use as fuel on Mars. Many of the proposed techniques utilize the well-characterised atmosphere of Mars as feedstock. Since this can be easily simulated [...]
