-> Science -> Applied -> Ecology Solar-based conversion process only works if a photocatalyst — a material that reacts with light — is used to convert the CO2 into hydrocarbons. A photocatalyst that utilizes the most solar energy possible is the best option.
One popular photocatalyst candidate for the job has been titanium dioxide, also called titania, because it can powerfully react with oxygen. But so far, researchers haven't been able to make titania perform adequately despite experimenting with a variety of forms,...
Vertical wind turbine
-> Science -> Applied -> EcologyAs wind industry claimed that vertical turbines are ineffective, I developed a project to prove this theory wrong.
I designed a windmill consisting of 8 turbines, each having 4 structural steel wind scoops. The vertical turbine has 32 scoops in total and the wind can blow from any direction making the blades spin. By now the prototype is working flawlessly and even the slightest breeze of wind can make its blades spin. The turbine has a 12 feet diameter and is 36 feet tall.
Reflective plants against global warming
-> Science -> Applied -> EcologyThe reflectiveness of the ground is a well-known factor that is taken into account in the main global warming simulation models. This factor having a significant impact on the results from such simulations, it is straightforward to think about fighting against global warming by acting on the reflectiveness of the plants we cultivate ! Governments should implement tax-cuts on farmers that grow reflective crops. We could also genetically modify some plants to change their colours.
The Quinn solution
-> Science -> Applied -> EconomyWho's to blame for the current world financial crisis? Among the more plausible culprits are Wall Street's wizards of “securitization,” who packaged mortgages and other loans into ever more esoteric financial instruments. But what securitization has caused, it can also cure — or so says Stephen Quinn, an economist at Texas Christian University.
The collateralized debt obligations and other securities at the heart of the current mess are worth a certain amount on paper, but their real...Tagged as Financial Crisis, Finance, Wall Street, Securitization, Mortgages, Quinn, Solution, Firm.
-> Science -> General -> MathematicsIn number theory, the Elkies trinomial curves are certain hyperelliptic curves constructed by Noam Elkies which have the property that rational points on them correspond to trinomial polynomials giving an extension of Q with particular Galois groups.
One curve, C168, gives Galois group PSL(2,7) from a polynomial of degree seven, and the other, C1344, gives Galois group AL(8), the semidirect product of a 2-elementary group of order eight acted on by PSL(2, 7), giving a transitive...Status:
Reviewing in progress: The status of this I-dea is not yet decided, the reviewing procedure in progress.
Worth considering: This I-dea is worth being given more consideration. The precise goal, mean of application, technology used, its cost, and other details should be discussed.
Worth concretisation: The I-dea is worth being concretised. It is waiting for investments and/or partnerships.
In production/commercialisation: The I-dea has been concretised to production and/or commercialisation.
Explanations needed: The description of this I-dea isn't clear enought to understand its goal and mean.
Already exists: This I-dea has already been concretised. It is available to the public, or will be in a near future.
Technologically unfeasible: The technology needed to realise this I-dea won't be available for at least a century.
Financially unsustainable: Compared with the potential return on investment, the huge cost of this I-dea makes it unsustainable.
No market: Too few people are likely to be interested in this I-dea.
