Can You Hook Blue LED Lights to a Pc Motheboard? Just a Normal Motherboard?

If you are talking about led strips, then no. Most of them connect to the power supply via the 4 pin molex. However some can connect to the 3 pin fan header on the motherboards.

1. Gateway desktop LED lights up, but computer doesn't turn on?

it probably just does not like XP, try re-installing XP (maybe a load corruption) or a different OS

2. Hooking up led lights to car battery?

Instead of going directly to the battery, take your power lead from a switched circuit through the cars fuse box. Then it will shut off when you turn off the ignition

3. Boosting 18 V drill battery to 60 V to power LED lights, problems with voltage stability

I believe that your batteries may be too small.I use modules that look very much like (probably identical) for my LED yard lights. However, 7 Amps. I removed the original power supply and use these modules instead.The smallest battery I use is Dewalt Flex-Volt batteries - I have both 6Ah & 9Ah at 20 Volts. Do note that Dewalt plays a little loose with their battery voltage ratings - most people would call these 18V packs rather than the 20V rating that Dewalt uses. My battery packs are 3P5S with either 2AH cells (6Ah) or 3Ah cells (9Ah). These packs can be switched into 60V mode by means of a mechanical switch contained in the battery pack but I am using them in 20V mode.My portable lights work extremely well with those power supplies. Do note that I am using the power supplies in Constant Current mode. The open-circuit voltage is set to be a couple of volts higher than the maximum voltage that the LED lamps will ever require and the current is set to the proper value.I've also used those modules to power 4' LED strip lights (fluorescent bulb replacement). I am using one module per lamp, directly feeding the LED array inside the tube. In other words, I am not using the internal power supply within the tube. Also great performance using the Dewalt battery packs.

4. City of the future communicates using solar panels

Manganiello compares the current solar infrastructure with a creature that cannot see or feel. It is his ambition to provide solar cells and modules (groups of electrically connected solar cells) with these senses and enable them to communicate with each other and with the world. The crux of the technology involves deploying the existing infrastructure of a solar cell not only to convert light (photons) into charged particles (electrons), but also to provide them with sensors that can extract information from the light waves and enable them to broadcast their own light messages using LEDs or other light sources. But Manganiello also has plenty of ideas for more creative applications for integrating energy generation and information transfer, in particular as part of the increasingly wide-scale integration of solar cells in urban environments in the coming years, where solar cells could be built into windows and walls, but also indoors to capture and reuse energy from artificial light. For example, a desktop covered with solar cells could convert the light produced by a desk lamp into energy to wirelessly charge a phone. The electrical engineer holds his outstretched hands in front of his chest to illustrate two buildings opposite each other in his vision of the city of the future. If their walls can not only generate energy, but also exchange information through multifunctional solar panels, the buildings will be able to communicate with each other. For example, one building could report that too many washing machines are being used in it and that it requires extra power from its neighbour. Or they could share an internet connection using light signals. This could be of real benefit with the increasing scarcity of radio waves used for Wi-Fi. In time, all the buildings in a city will be able communicate with each other and warn each other in the event of a fire, storm or flood, for example. 'LED lights in an office building could send a signal to a sensor on your phone warning you to leave the building,' says Manganiello. Manganiello explains that he has thousands of ideas for experiments to bring these futuristic scenarios closer. 'Unfortunately, at any given moment we can only work on a tiny percentage of these, which is what I find most frustrating about my work.' He estimates that it will take about 10 to 15 years before new buildings will be able to communicate with each other through solar cells built in to their walls, however the first applications should start to appear in the coming decade. Manganiello is impatient to get moving. 'Energy is playing an increasingly important role in our lives. Our biggest fear today is that our battery will run out,' he says. The graphs that made such an impression on him as a student twenty years ago have shot up even further. 'I want to believe that we can solve this, but when I see how societies, governments and the industry are responding to these issues, I sometimes lose heart.' He sighs deeply when asked to provide an example of such a response. 'The main problem is the resounding lack of a response, and the low priority given to sustainability.' Despite the severity of the problem, optimism and fascination still prevail in the interview with Manganiello. He concludes by sharing his favourite scenario for a sustainable future that the Photovoltatronics group hopes to achieve. He describes two cars, covered with solar cells which provide a large part of their energy. A deer suddenly jumps out in front of the foremost car. Even before it has applied the brakes, its rear lights rapidly transmit a signal to the solar cells on the vehicle behind: 'Warning, I am about to brake!' At the same time, the urban traffic control centre sends signals via street lamps to solar cells on the roofs of passing cars to control traffic and prevent congestion and air pollution hotspots. 'I think this is the best example, because safety is the main bottleneck in the development of self-driving cars, while this technology can make life easier and more sustainable. I think the Photovoltatronics research group can provide an important boost to the development of self-driving cars, and it is a privilege to be able to contribute to this.'
