I think the hundred dollar laptop is a great idea. only I have one question if you are constantly recharging the batterie using solar or some other methed. Wont that affect batterie life after only a short amount of time. I know my laptop batterie lasted only about one year because I kept recharging it all the time and now it only holds about 20 minutes of charge. |

NiMH batteries do not suffer from "memory effect", in fact NiCd batteries don't normally either. But, both types do suffer from voltage depression; when they are fresh and new they give a voltage of 1.2v per cell so 8 cells will give 9.6v, a useful amount. But if the cell is over charged or just always on trickle charge the cell voltage soon drops to just about one volt per cell; just 8v total, the equlivent of removing an entire cell. The interesting thing is voltage depression does NOT effect the total capacity of the battery. I have NiMH and NiCd that are completely depressed (hmmm) but they still do the job as well as they did when new. |

The problem with this is the discharge graph [http://www.uniross.com/UK/industrial/Product%5Ccharacteristics/010302]. You will notice that it's mostly flat so some designers take the 1.2v as gospel and design thier electronics to shutdown at 1.1v. If the battery is depressed by 0.2v this line comes in at about 10%..15% of the way into the capacity so you only get 10%..15% of your two and a bit hours of charge ... 20 minutes...

I think the hundred dollar laptop is a great idea. only I have one question if you are constantly recharging the batterie using solar or some other methed. Wont that affect batterie life after only a short amount of time. I know my laptop batterie lasted only about one year because I kept recharging it all the time and now it only holds about 20 minutes of charge.
The Time for the OLPCWiki in Spanish has come...
Y aqui les dejo la primera... página...
Me permito someter a su consideración los siguientes artículos que describen un IMPORTANTE avance tecnológico, que ayudará a cerrar la brecha entre los países pobres y los desarrollados.
La adopción de estas computadoras y su distribución en México, permitirá:
1.- Un salto cuántico en la calidad de la educación al permitir que cada niño, jóven y adulto posea su propia PC con acceso a Internet.
2.- Permitirá desarrollar una política de NO EXPORTAR TRABAJADORES, sino IMPORTAR TRABAJOS, al facilitar la realización de trabajos virtuales desempeñados sobre la red.
3.- En Australia, donde las distancias entre los vecinos no se miden en metros, sino en HORAS DE VUELO, los médicos han desarrollado mecanismos para atender a sus pacientes a través de Internet, la aplicación de estas técnicas, podría poner a los médicos de México al alcance de toda la población rural y de pequeñas comunidades, sin necesidad de construir costosas clínicas y hospitales por todo el territorio nacional.
4.- Permitirá a los jubilados y discapacitados trabajar desde sus casas, brindando consejos y ayuda a los ciudadanos para sus problemas de...
a) Tareas y Estudio,
b) Domésticos y familiares,
c) Emprendedores y Pequeños empresarios,
d) Tr.amites y apoyos Gubernamentales,
e) Asesoría en Turismo. y haciendo traducciones, apuntes y otros trabajos.
Todo con cargo a las tarjetas de todito.com de los que requieren ayuda, de lo cual un 15% o 30% queda al organizador y el resto (85% a 70%) se entrega al asesor o tutor.
5.- Desarrollar una industria propia de computadoras, mediante la contratación del la fabricación y ensamble de sus partes en México.
Gracias por su atención; agradeceré una respuesta franca, breve, clara y práctica a este mensaje, con su opinión y aportaciones, así como la justa oportunidad de participar en el desarrollo de los conceptos expuestos.
Atentamente,
Ing. Dagoberto Gmo. Flores Lozano Consultor en Ing. Industrial y de Sistemas, desempleado. Ex-Investigador y Profesor Universitario, Ex-becario de la Fundación Ford, en Berkeley, Aguascalientes, AGS. MEXICO dagoflores@prodigy.net.mx
software to add and hands to crank
A version of Touch Typing software to teach these kids to touch type, the faster you can work with a keyboard whatever age you are then the faster you can get on with solving the worlds problems and letting the world know about your solutions... ' eg unjustified government spending on military budgets that will eventully only lead to one thing, more War to justify more spending etc..."
And does someone not need to make clearer in your marketing for support of this project that it does not have to be the same person who turns the crank as types at the keyboard, that there is a shortage of electricity in developing nations not hands to turn cranks?
The computer is a really good idea.
I wish, please do they sold in every high developed countrys - FOR 150.- Dollar! (To elemantary schools etc. its a perfect machine.) And then you can go down with the price for poor countrys about 50.-$, better!
