Relativistic Phase Displacement Space Drive - Warping Space Time with Phased Standing Waves

submitted by: MFerreiraJr

It is a brief explanation about a relativistic space propulsion system which uses a lattice/matrix of Phase Displacement Space Drives, producing crisscrossing pattern of Phased Standing Waves, to generate a sequence of spinning waves for causing a FTL moving force, in order to warp spacetime, enabling fast interstellar travel in an energy-efficient way.

Cleaner Fossil Fuels

submitted by: RASEIBoulder
Authors: Dag Nummedal. Reduction of carbon emissions and enhancement of national energy security are desirable goals. Discussions of how to realize these goals, however, generate a lot of heated debate – not all of it illuminating. An accelerated switch to renewable energy may seem like a logical push, yet the vastness of the global energy system is such that even the most optimistic scenarios for development of renewables are not going to bring about a cleaner atmosphere fast enough....

Economic Limits to Oil Supply: A Non-Hubbert Curve View

submitted by: RASEIBoulder
Authors: Richard S. Bishop and Wayne L. Kelley. Historically, questions of oil supply have been addressed by citing volumes of reserves and/ or resources. Supply, however, cannot be estimated from volumes alone but must include economic considerations. An optimistic outlook on global oil supply commonly will include large volumes of unconventional resources or undiscovered fields. While very large` such resources cannot add proportionately large supply rates due to logistical limitations,...

Large, Solution-Processable Graphene Quantum Dots as Light Absorbers for Photovoltaics

submitted by: li.liangshi
Graphenes have very attractive properties for photovoltaics. Their tunable bandgap and large optical absorptivity are desirable for efficient light harvesting. Their electronic levels and interfacing with other materials for charge transfer processes can both be tuned with well-developed carbon chemistry. Graphenes have also been shown to have very large charge mobilities, which could be useful for charge collection in solar cells. In addition, they consist of elements abundant on Earth and...

Interstellar Space Travel using Phase-shifted Electrodynamic Propulsion

submitted by: MFerreiraJr

It is a brief explanation about phase-shifted electrodynamic force (f ≥ c/L) causing electrodynamic drag, and consequently, generating propulsion in the outer space, and perhaps enabling fast interstellar travel.

Just entering the microcosm of atom matter where it is able to absorb and emit energy, still having the possibility to obtain energy from the mass of matter which can be found everywhere. Interestingly, E = mc² does not contain any reference to a particular substance, but there is no need, for one gram of air, water or gram per gram of cosmic particles, is also a gram of mass. So our new role is important to release any material amount of energy in mass that surrounds us and which we use...

Stephen Hawking's Warning: Abandon Earth—Or Face Extinction Let's face it: The planet is heating up, Earth's population is expanding at an exponential rate, and the the natural resources vital to our survival are running out faster than we can replace them with sustainable alternatives. So, according to famed theoretical physicist Stephen Hawking, it's time to free ourselves from Mother Earth. "I believe that the long-term future of the human race must be in space," "It will be...
