How to make solar cells (DIY/homemade solar cell)
Cuprous oxide is a semiconductor, just like doped silicon, and was one of the first materials experimented with as a solar cell. But its efficiency was found to be so low that people stopped trying, though the occasional set of experiments are still done in research labs and papers published. It was also used to […]

Question by lordmysterious12: Please, need a real scientist’s answer to this long & complex question (not for school)? Thanks for looking at my question. This is very complicated and more than a little unusual, so please, if you’re just guessing or think you might know, don’t answer. Please only answer if you’re actually a qualified […]
Pininfarina Cambiano Concept Car In Details – Concorso d’Eleganza 2012
Another concept car I saw during the 2012 Concorso d’Eleganza in Cernobbio was the Pininfarina Cambiano. The car is an electric plug-in range extended car and the drive system is constituted by four Magneti Marelli electric engines, one for each wheels. The car has an autonomy, in the urban cycle, of about 200 kms and […]
What’s the quickest way to get to the planet “Milla J.?”?
Question by WhiteWolf359: What’s the quickest way to get to the planet “Milla J.?”? Since it has now been established beyond doubt that the Planet Milla exists (where all women look exactly like Milla Jovovich), and my secret NASA source tells me it’s near Wolf 359, a red dwarf star approximately 7.76 light years from […]

how does solar enegy convert to electricty?
by Takver Question by Dylan H: how does solar enegy convert to electricty? Best answer: Answer by mckBasically, the solar energy is converted to heat (since the black panels absorb the light and therefore more heat), which then heats water, making steam, which rises up through a tube, causing a turbine to spin, creating a […]
Cheap Solar Power pt1
Using some scraps around the homestead I built a solar panel mount. Using some old car batteries and few bits for the junk yard you can build a battery charging station that can be used independent from the power grid. In WROL this unit will be very useful to charge computers, I phone, I pad, […]

What applications of Atomic Hydrogen exist, apart from its use in welding?
by jerryoldenettel Question by Idanre Magus: What applications of Atomic Hydrogen exist, apart from its use in welding? The Oxy-Hydrogen flame burns at up to 2800 degrees Celsius, but the Atomic Hydrogen flame burns at up to 4000 degrees Centigrade. I first learned about this in a couple of old Chemistry textbooks I acquired. One […]
