BULB AND BATTERY STORE FULL
So in a day which has 4.5 hours of EQUIVALENT full sun you get 4.5 kWh/m^2/day. One standard sun = 1000 W/m^2 or 1 kW/m^2 so in 1 hour you get 1 kWh/m^2. I use the term SSH or Sunshine-Hours for what they call kWh/m2/day.
The marvellous Gaisma site for Kathmandhu says that the average daily sunshine hours by month, January to December are To work out PV (photovoltaic) panel Wattage needed you need to know how much solar insolation is available. You need somebody who know what they are doing to do this as laptop destruction is made easier by playing in this way. Use of an inverter adds extra inefficincies.įor (almost) best possible efficiency you may be able to supply battery power to the Vostro's actual battery connections. If at all possible run the laptop or laptop charger directly off the battery.
The suggested 60 Watt panel will not be too small for you. I am concerned about the battery too, in term of efficiency and environmental impact. How do I find out what solar panel I need? (A local store which I don't really trust, proposed I buy their most expensive model, a 60W panel)

I own a Dell Vostro 1510 laptop, which will run all day long (let's assume 24 hours as I need to download data from a slow Internet connection), and I will use an energy saving bulb to light up my desk at night.įrom what I understand, I need a solar panel, connecting into a power controller, connecting into a battery, connecting into an inverter.
In spite of my interest, I have always been very bad with electronics: I need please a case-specific and for-dummy answer. I have looked into this Q&A already and found some answers, some of which are too broad or assume I know something about electronics. In order to work, I need to have continuous supply of energy for my laptop and a bulb a night. We’re confident she asked him sometime, ‘Thomas, what are you going to do with your life?’ That was a very good question and he replied with action! So what are YOU planning on doing with YOUR life, young person? How are YOU going to improve your world? We hope you agree that’s a deeper issue than making a light bulb.I reside in Kathmandu where the current power supply is so weak one has to face between 8 to 18 h power cut per day. His mother home-schooled him, and taught him what he knew. He came from immigrant stock that arrived in America in search of a better life. Thomas Edison was not the son of some wealthy person who sent him to Harvard to learn science. We showed you this experiment to make a light bulb, because we wanted you to imagine what’s possible for you too. He found many more things to do with the amazing phenomenon of electricity captivating America. How This Experiment Inspires Usīut Edison’s inventive mind was not done yet, no not done yet by far. But that’s only because an American fellow named Thomas Edison came up with the original idea, and invented a working version in 1878 while he was still a young man. Sure, we have to agree with you too, because we could purchase a better light bulb at almost any convenience store. So watch him demonstrate his ideas, and share the technical explanation at the end that wraps up the science.īy now you’re probably thinking, oh wow that’s no big deal. The fellow in the video explains it nicely enough. Our experiment to make a light bulb illustrates the point the current voltage must be high enough to heat the filament, but not enough to melt it. Now an incandescent light bulb is a filament through which electricity flows, and which makes that filament hot enough to glow. So we delayed using batteries, light bulbs, insulators, and conductors in simple experiments, in favor of something with greater potential. However, we believe there is a deeper message behind this for all of us to share.

That something is how to make a light bulb at home. There’s been a slight change of plans from last week.We came across something that challenged our assumptions and we wanted to share.
