An average bolt of negative lightning carries an electric current of 30,000 amperes (“amps”) — 30 “kiloamps” (kA), and transfers five coulombs of electric charge and 500 million joules — 500 “megajoules” (MJ) of energy. Large bolts of lightning can carry up to 120 kA and 350 coulombs. The voltage is proportional to the length [...]

in-situ resource utilization (ISRU) describes the proposed use of resources found or manufactured on other astronomical objects (the Moon, Mars, Asteroids, etc.) to further the goals of a space mission. According to NASA, “In-situ resource utilization will enable the affordable establishment of extraterrestrial exploration and operations by minimizing the materials carried from Earth.” ISRU can [...]
Structure The structure of a robot is usually mostly mechanical and can be called a kinematic chain (its functionality being similar to the skeleton of the human body). The chain is formed of links (its bones), actuators (its muscles), and joints which can allow one or more degrees of freedom. Most contemporary robots use open [...]
Motorcycles Companies such as Zero Motorcycles and Vectrix have market-ready all-electric motorcycles available now, but the pairing of electrical components and an internal combustion engine (ICE) has made packaging cumbersome, especially for niche brands. Also, eCycle Inc produces series diesel-electric motorcycles, with a top speed of and a target retail price of $5500. Peugeot HYmotion3 [...]
Starting in 1951, he received generous support from the Research Corporation in New York, and moved to Hawaii. In the 1950s he wanted to return to active studies but much of the field was already filled with very large and expensive instruments. Instead he turned to a field that was being largely ignored, that of [...]
This section includes some minimal descriptions of methods, to give some feel for such a building’s practicality, provide indexes to further information, and give a sense of modern trends. Water There are many methods of collecting and conserving water. Use reduction is cost-effective. Greywater systems reuse drained wash water to flush toilets or to water [...]
Power stations As of October 2009, the largest photovoltaic (PV) power plants in the world are the Olmedilla Photovoltaic Park (Spain, 60 MW), the Strasskirchen Solar Park (Germany, 54 MW), the Lieberose Photovoltaic Park (Germany, 53 MW), the Puertollano Photovoltaic Park (Spain, 50 MW), the Moura photovoltaic power station (Portugal, 46 MW), and the Waldpolenz [...]
SunPower has recently announced a number of projects around the world that utilize its patented solar tracker technology. The company maintains a market-leading position in Spain with more than 61 megawatts installed or under construction; recently completed a 2.2-megawatt solar power plant in Mungyeong, Korea; and the largest solar installation in the U.S., the 15-megawatt [...]
