Spaceelevator 20091205 (student preso)
A space elevator is a proposed type of transportation that would transport materials from Earth's surface to space using a 35,000 km long cable anchored to the Earth's surface at one end and a counterweight in space at the other. The idea was first proposed in 1895 but recent advances in carbon nanotube strength and durability have made the concept more feasible. A space elevator could provide cheap access to space at an estimated $100 per kg compared to thousands per kg for current rockets. It would enable practical applications like removing nuclear waste from Earth and generating solar power in space.
Space elevator
The document discusses plans for building a space elevator using carbon nanotubes. A space elevator would consist of five major sections: the anchor station on Earth's equator, the ribbon/tether made of carbon nanotubes extending into space, counterweights beyond geostationary orbit, climbers that would ascend and descend the tether, and an anchor platform in the ocean. Carbon nanotubes are proposed for the tether due to their immense strength, resilience when bent, and stability at high temperatures. A space elevator could provide low-cost access to space and open up opportunities for solar power satellites and exploration of the solar system.

HOI presentation barry hansen magnetic launches
Barry Hansen, as part of our Hands-On Ideas series, describes how he was inspired to build his own magnetic launch devices. Going from his science fiction influences through the theory and project iterations, he shows how a maker can explore space transportation technology.
Space future
The document discusses plans for building a space elevator to provide cheaper access to space. It proposes constructing an initial 20 ton capacity elevator using existing or near-term technologies like carbon nanotubes. The elevator would use climbers powered by solar panels to transport payloads at a low cost of $250/kg to various orbits and destinations in space. Some challenges include developing strong and lightweight tether materials, but advantages are low operations costs, no launch vibrations, and safe space access without rockets.
M2p2
The document summarizes the Mini-Magnetospheric Plasma Propulsion (M2P2) concept. M2P2 uses a magnetic field and plasma injected from a helium source to create an artificial magnetosphere around a spacecraft that interacts with solar wind particles to provide thrust. A prototype M2P2 system could accelerate a 100-200 kg spacecraft to velocities of 50-80 km/s using only 15-30 kg of propellant over 3 months. M2P2 offers potential advantages over conventional chemical rockets and solar sails by providing continuous thrust with less fuel and mass.
Loudspeaker
The document discusses how loudspeakers work by using magnetic fields created by electric currents. It explains that electric currents produce magnetic fields and that loudspeakers contain a coil of wire that acts as an electromagnet when current passes through. The magnetic field from the electromagnet vibrates a cone to produce sound waves that are amplified and played through the loudspeaker. However, details of how exactly the loudspeaker converts electrical signals to sound waves are not provided.

This document proposes developing an ultra-light solar sail without a plastic backing for use in interstellar travel. It summarizes the proposed scope of work, which includes analyzing the reflectivity and engineering constraints of nanometer-thick aluminum sheets and grids, as well as doped carbon nanotubes. Preliminary analyses show these ultra-light concepts could achieve accelerations over 100 times greater than conventional solar sails and reach distances like Pluto in months or 10,000 AU in decades. The document recommends a Phase II experimental program to fabricate and test nanoscale reflectors and verify their properties.

1) The document discusses various proposals for future space travel, including interplanetary travel using techniques like ion drives, solar sails, and nuclear thermal propulsion.
2) For interstellar travel, it describes proposals like nuclear pulse propulsion, fusion rockets, and beamed propulsion that could potentially reach nearby stars within 100 years.
3) Even more advanced technologies, like antimatter rockets, wormholes, or altering the properties of spacetime, would be needed for intergalactic travel and to achieve faster than light speeds as required to reach the Andromeda Galaxy.
Question 1 group 1
The document discusses how drones fly and are powered. It explains that lift from rotors pushing air downward equalizes the force of gravity, allowing for hovering. Drone propulsion comes from jet engines or electric motors powered by batteries that are often recharged with solar panels. The efficiency of converting sunlight to electricity via solar panels is discussed, currently around 35%. The document then considers whether a drone depicted in a movie could realistically fly continuously for 10 years using only solar power, determining it is not currently possible due to technological limitations of solar cell efficiency.
Magnetic Propulsion
1. David Goodwin proposes an electromagnetic propulsion system for spacecraft that uses supercooled electromagnets vibrating at 400,000 times per second to provide thrust.
2. The system would use a nuclear reactor to power solid-state switches that pulse the electromagnets, generating a vibration that could theoretically propel a spacecraft at a fraction of 1% the speed of light.
3. While speculative, if successful the system could enable missions to the edge of the solar system and beyond, faster than any chemical rockets. Testing is needed to determine if the magnets can truly generate unidirectional thrust.

Why The Solar System's First Space Elevator Will Likely be Martian
Space Elevators involve lowering a tether from synchronous orbit down to the surface of a planet, then electromechanically hauling payload up the tether to space. While theoretically possible, the concept has been shown to be infeasible on Earth until the development of mass-produced ultra-lightweight materials with specific tensile strengths of ~40 MPa/kg/m^3 (~20 times stronger than Kevlar). Such strength is within the theoretical limits of Carbon Nanotubes (CNTs), but it is not known when practical commercially available CNTs will reach this required strength. On Mars, however, the lower surface gravity and lower synchronous orbit altitude allow a space elevator to be built from materials with specific strengths of only ~5 MPa/kg/m^3, which is within the range of existing CNTs, provided such materials could be mass produced. The required tether mass and length is also significantly reduced from 9,000 tonnes and 155,000 km at Earth to only 1,500 tonnes and 70,000 km at Mars. The driving engineering limits for construction of a space elevator will be compared between Earth and Mars, and an industrial/economic analysis will be presented to quantify the project scale, timeline, cost, and expected economic activity Mars will likely have to support before a Martian space elevator would become a profitable investment.

Aurora
This document summarizes the key scientific concepts relating to the aurora phenomenon. It outlines the timeline of major discoveries, including the identification of the 11-year sunspot cycle and measurements of aurora height. The document then explains the underlying physics, such as the role of the solar magnetic field in generating solar activity like coronal mass ejections that interact with Earth's magnetic field. This interaction causes plasma to collide with air particles, exciting them and causing the colorful lights of the aurora through atomic excitation and radiation. The color and altitude of auroras are also summarized.
Seminar on solar sail
Solar sails use radiation pressure from the sun for propulsion and have minimal moving parts. They produce very small thrusts but can be used repeatedly over long periods. A seminar discussed the physical principles behind solar radiation pressure and how it produces small forces on sails. Attitude control is needed to maintain the craft's orientation against various forces. Testing is challenging on Earth but applications could include satellites for trajectory corrections and missions close to the sun. Various sail configurations and materials have been proposed but deployment challenges have limited real-world testing until Japan's 2010 IKAROS mission, the first to use a solar sail as a primary propulsion system.

Space elevators are incredibly tall theoretical structures that connects the earths surface and outer space, beyond the geosynchronous orbit (35,800 km). The structure acts as a continuous and viable channel by which payload can be send in to space.
the space elevator
This document discusses the concept of a space elevator, which would be a fixed structure extending from Earth's surface into space to transport material into space at a lower cost than rocket propulsion. The key components of a space elevator would be a base station/anchor, cable made of carbon nanotubes, climbers to transport payloads up the cable, and a counterweight in geostationary orbit or beyond. Challenges and potential solutions are outlined. Applications could include solar power satellites and facilitating exploration and development of the moon, Mars, and Earth orbit. The document argues that a space elevator is achievable in the near future with reasonable investment and could revolutionize access to space.

Space elevators are tall structures that could transport satellites and shuttles into space without rockets at a low cost and with minimal environmental impact. They work by using a ribbon that extends over 60,000 miles into space and climbers that ascend the ribbon. The main challenges are the strength of materials needed to build it and dealing with space debris, but carbon nanotubes show promise and locations in international waters could help address political issues. If built, space elevators could provide cheap and green access to space for activities like space tourism and solar power satellites.

Space elevators are proposed structures that would transport satellites and shuttles into space without using rocket fuel by extending beyond the Earth's atmosphere. The elevator would use a ribbon made of carbon nanotubes anchored to the Earth and extending over 62,000 miles into space. Climbers attached to the ribbon would carry cargo and humans into space at 200 km/hr. Major challenges include damage from space debris and technical difficulties, but the elevator could provide low-cost space access without pollution if engineered successfully. Private companies and governments are working to develop the necessary technologies to potentially build a functioning space elevator by 2050.

Space elevators are tall structures that could transport satellites and shuttles into space without rockets at a much lower cost and with less environmental impact. They work by using a ribbon that extends over 60,000 miles into space and climbers that ascend along the ribbon. Major challenges include the strength of materials needed and impacts from space debris, but carbon nanotubes show promise and companies aim to build a working elevator by 2050. Space elevators could provide cheaper and greener access to space than current rocket launch systems.

Interstellar Travel
Ok, we found a new Earth nearby. Next question is: how do we get there?
The amazing challenge to get mankind to become an interstellar species and how we could potentially get there.
The different technologies involved and the key challenges to overcome.
Welcome to teh next chapter of mankind.
Einstein theory of time travel
This document discusses several theories of time travel, including Einstein's equations allowing for time travel under certain configurations of matter and energy, Gödel's mathematical solutions showing time travel is possible if the universe rotates, and Kip Thorne's work developing a serious proposal for a time machine using wormholes. While time travel remains theoretically possible, significant technological limitations exist, such as a lack of means to generate the exotic matter needed to stabilize wormholes. Paradoxes also pose challenges to changing the past through time travel.
The space elevator
The document discusses the concept of a space elevator, which would consist of a cable anchored to Earth and extending over 60,000 miles into space. The cable would be made of carbon nanotubes and allow cheaper access to space than current rocket methods. Key components would include the ribbon, anchors on Earth and in space, initial spacecraft to deploy the ribbon, climbers to travel along the ribbon powered by lasers, and overcoming challenges like radiation, debris, and climber malfunctions. The space elevator could enable low-cost delivery of materials and people to space for activities like solar power satellites, space exploration, and telecommunications.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

A review on techniques and modelling methodologies used for checking electrom...
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Space elevator
- 1. Space elevator Prepared by: Abdelrahman Abouali Mechanical Engineering Department Near East University
- 2. Introduction • Science went deeply into sciences including the space. • What do we hope for the future ? • Do we have the best way to explore the space ?! Let’s have a look
- 3. What is the Space Elevator? • Tall theoretical structure “tower” that stretch beyond the earth’s atmosphere. • This idea first envisioned by Russian rocket scientist Konstantin Tsiol kovsky. • Normal rockets costs too much, what about using easier and costless method !!
- 4. Theory of space elevator • A cable attached to the surface and the space beyond • Forces would hold up the cable. • Gravity and centrifugal force. • Climbers will repeatedly climb the cable • Climbers could take the way up and down • That is applicable to other planets (no material or gravity probs)
- 5. Why would we built one ? • Normal satellite costs $160,000,000 • $ 22,000 for 1-kilogram payload • Cost will be billions • With space elevator cost decreases • one hundredfold to $ 200 per kilogram
- 7. Maybe a space elevator costs more than the normal rocket launch, an expensive one will cost 20 Billion dollars but we can collect the losses after the first 1 million tons.
- 8. Proper places to build space elevator Space elevator in Earth is not easy. More useful places to build it Moon and mars for examples We will use the existing materials
- 10. Safety and security • Normal rocket lunch process looks like Riding a giant explosion. • As is Coming back trip. • Space elevator gives us a safe access. • No explosion! No Dangerous launch!
- 11. The figure shows us Failures and successes statistics about launches through 57 years
- 12. Applications • Large solar panel towers in space. • Maximum amount of sunlight possible all the day. • High performance telecommunications systems. • “Space train“ adapted from science fiction novels. • Moon,Mars and Solar System Exploration.
- 13. How would we build one ?! Main components: • The Tether • Anchor • Climber • Counterweight
- 14. Carbon nanotubes • Light, flexible and ultra-strong metal • At least 1000 times stronger than steel • Flexible as plastic • Tiny rolled three-dimensional carbon tubes • Young’s modulus 6.25 times that of steel • Single and multi-walled tubes
- 15. Probable Challenges • The flaw of tower idea (weight of the tower) • Tensile force on the tether • Lightning, wind, clouds • Climbers Errors – Retrieving process • We need to build it right in the first time • Or we head to the moon • 200 years life to overcome damage
- 16. Energy • Wireless energy transfer: - Free-electron laser system - It requires two physical installation points • Some material structure • Store the energy in the climber such as nuclear energy. • Solar power - the weight limits the speed of climber.
- 17. Conclusion • Difficulties exists but still intriguing idea • Engineering = Overcoming obstacles • The future is a big secret
- 18. Any Queries??? Thank you for your time
