I’ve just started a solar charging test with the ASUS Vivotab Note 8 Windows 8.1 tablet (running on the Intel Baytrail-T platform.) Normally it would require a 2A USB output to charge it but lets see what the 1.2A output of the Changers solar power pack can do. The tablet is registering that power is connected […]
I’ve just finished a full review of the Toshiba Encore WT8 Windows 8.1 Tablet. As expected it’s incredibly efficient, and perfect as a solar-powered PC. You can do everything on this. From web browsing to video editing to Office work with a full keyboard and external monitor.
Using the sun to power consumer electronics is horribly inefficient and expensive but as technology advances, the process gets a lot better. PCs are running in 5W now compared to over 10W just 5 years ago. Screen technology is getting more efficient and the solar equipment used to collect and store the energy from the […]
How close are we to powering our tablets with on-device solar cells? In a recent test I ran a tablet connected to the internet at an average 200 mW. That’s screen off, wifi connected and polling in the background to update emails, location, twitter and other processes. It’s nothing really surprising because most of the […]
While I’m in the mood, freshly inspired by the e.quinox project, I want to write about a few more super-efficient ‘PCs’ that I’ve been using recently. Both are based on ARM CPUs and show they way for 2011. Later in this article I’ll talk a bit more about technologies to watch out for.
Last Thursday I spent a lot of time analyzing exactly how efficient my charging solution was with a real-life test. What dropped out was a rather poor picture of how inefficient the whole solar charging setup was. From over 1.2KW hitting the area of my solar panel I managed to use about 19W. That’s a […]
In a recent comment here, someone asked why the Lead-Acid battery was needed. Its probably not too clear in the video why I use it so I reproduce my answer (which comes from the best of my knowledge!) here. There are two main problems with charging Li-Ion batteries from Solar panels. Firstly, Li-Ion batteries (in […]
I learned a long time ago that WiFi Internet access is not a truly mobile Internet access solution. Its a solution for multi-location access but not a full mobile solution. Fortunately the mobile telephone carriers offer Internet access too and it ‘aint bad!Its going to be the perfect solution for the Solar-UMPC tour. In Europe, […]
They are expensive and inefficient. Solar panels need to develop a lot before they can provide the average man on the street with enough energy to supplement a worthwhile portion of his energy intake. Mind you, the average man is pretty inefficient. Cars, lighting, heating, cooling. We sap up energy like there’s no need to […]
Before I talk about the video I just want to say “where’s the damn weather!” Lesson number one in the Solar-UMPC project is that the weather is chaos and if you live in mid-northern Europe, you can’t rely on it as a source of instant energy. You’ll see how I’ve had to adapt my solution […]
