Lo que ves en la imagen, es lo último de Sharp para los hogares digitales y aquellos preocupados por el ahorro de energía o al menos la búsqueda de alguna fuente lo más ecológica posible, como por ejemplo el sol.
El Sharp Lumiwall es un cristal con paneles solares en su interior de manera que durante el día almacena energía eléctrica (y se vuelve opaco) mientras que por la noche actúa como una fuente de luz difusa.
Este tipo de noticias la verdad es que me encanta comentarlas aquí
Start getting prepared for summer days today, because now we can have one more solar gadget to play with. This is Solar ChumAlong solar panel which is not a breakthrough of course. We have seen a lot of these things along summer seasons, liked them frankly speaking. Solar ChumAlong is a bit different however. It has borrowed some of its features from huge and expensive solar power stations and yet has missed some everyday needed stuff. So ChumAlong is a compromise for free of charge solar energy but not a great whole-rounder with 400 USD price tag.
Solar ChumAlog has only one very strong feature to differentiate it from the other solar panels. Just like a sunflower, ChumAlong follows the sun as it moves along during the day. How important that is? Well, in a perfectly sunny day it can produce up to 50 percents more power than it would gather in static. Overall solar tracking system produces plus 30 percents to average figures. Making this possible made ChumAlong this expensive. Positioning requires a special Micro-controller Technology, worm gear axis shaft and optical sensors. And there we are, 400 USD for a portable solar panel. It is also easy to adjust and light to carry, but it has some drawbacks also. Solar ChumAlong is capable of producing 5 W only. And probably the worst thing is that the device doesn't come with a battery which you will obviously need, hence add at least another 30 USD for 12vdc battery expenses.
The LightCap is basically a solar powered water bottle which has a built-in LED light in its lid. It features a waterproof solar panel, battery pack, and "will stay bright for hours while the rechargeable Ni-Cad batteries will last for at least 300 cycles" on a four hour charge -- in sunlight. This device measures 8 ¼" tall and 3 ¾" wide with a 32 oz capacity. No word yet on pricing and availability.
Solar power has to be a long term investment to make an individual better off. Solar cells or panels are small productive and reliable today, they are not reasonably priced only. And what’s more, installation of a fully assembled solar cell complex will cost the same as the gears price and will take you intolerably long to finally set it to work for you. This is exactly why we have PICNIC Green Challenge and similar concourses giving money prices to people or enterprises that have figured out one or two environmental problems. Verdana Solar was one to get 100,000 Euros for its easy to install hence cheap solar panel. It is not yet on the market, but we hope the price will help to unleash it before summer.
Cutting costs of installation is one of the two redeeming features of Verdana Solar’s panels. The second one is the design of the thing which will look cool hanging out of your window or on you balcony. Don’t be misled by the picture by the way. These babies are pretty big - about half a size of a small window.
Technically there is nothing new in Verdana Solar’s kits. Thy have no battery so you will have to either buy one or plug a wall outlet directly to it but you should better have a battery. As you can see, there are different panel sizes, they all are addible to each other so you can buy a starter kit and then upgrade it with other panels. 600 USD for the first order of the biggest one and 450 USD for smaller.
You know when you come back to your car on a really hot day, you open the door and get blasted by hot stuffy air well this solar powered gadget solves half the problem, at least the hot air won’t be stuffy (and maybe a little cooler too).
The solar vent clips on the top of your window with the solar panel outside (and some air vent I assume) and a fan on the inside. It then sucks the hot stuffy stale air out of the car and replaces it with not quite so hot fresh air from outside. It’s certainly not a replacement for air con but a green and ecologically friendly addition.
About six months ago, we reported that Toyota was planning on putting solar panels on the Prius to power the air-conditioner. It has been recently been released that the famed Japanese motor company plans to release a car that is completely solar-powered.
As you can see on the photo, the solar panels are on the roof like solar panels of a house. This is only one way the car gets its power, as the company wants to supplement power by somehow attaching the car to the solar panels on the roofs of homes. This way, a car can be powered in a garage or parked outside.
Toyota is actually quite ahead of the solar power game. Their company in central Japan has solar panels on the roof that are equivalent in area to sixty tennis courts, and can produce enough energy to power 500 homes. That is enough annual savings for 740 tons of carbon dioxide emissions, which is equal to using 1,500 barrels of crude oil.
So is this the dawning of the age of the solar car? I used to think that a solar car was a useless invention, as most people drive at night. However, if it is possible to charge a car with solar power, then I guess we’d power our car in a manner similar to solar-powered cell phone chargers.
Originally, Toyota said that it would have the solar panels on the Prius by Spring 2009. However, a car that is entirely solar powered will take years of development, so we don’t know exactly when we will see Toyota’s solar car. I’m sure you will agree that it is a step in the right direction for a greener world.
You never know just what kind of underground pests you’re going to run into, so why not stay safe rather than sorry? The Solar Underground Pest Deterrent device won’t harm the environment in any way, and it won’t add to your monthly electricity bill since it comes with a built-in solar panel. Powered by the sun, it will help help drive away underground pests including moles, voles, and gophers.
The weatherproof anodized aluminum spike stakes into the ground, where it emits sonic vibrations every 30 seconds that irritate burrowing pests and compel them to disperse. The deterrent operates within a diameter of 94 1/2′, and the 4″ sq. solar panel charges an integrated battery during the day, even in low light and overcast conditions, so it operates both day and night. The panel fully charges within three hours in full sunlight conditions and will operate for up to eight hours on a full charge.
Nice to know that it comes with a replaceable rechargeable battery pack, all for $59.95 a pop. If dad’s an avid gardener and have been complaining about underground pests, why not get this for him?
MIT engineers have invented what they call a solar concentrator; solar windows for the home.
Solar concentrators contain special dyes that help the windows absorb light differently.
The edges of the windows have energy cells that collect energy from light.
Solar concentrators to be used in solar windows:
The beauty of the above concentrator technology is that it does not need to move the track the sun, it can exist in a window and still harness sunlight efficiently.
According to Discovery Channel.com and Science Magazine, project leader Marc Baldo, claims the solar windows can obtain energy from 40% of the sunlight.
Dr. Baldo also claims that the concentrator can increase the ability of standard photovoltaic (PV) panels by 50%. This is huge, allowing photovoltaics to absorb 80% of the light energy that hits them.
According to MITs website, these windows or the dyes, will be available to the public within the next three years.
Dr. Baldos research team, includes EECS graduate students Michael Currie, Jon Mapel, and Timothy Heidel, and postdoctoral associate Shalom Goffri from the Research Lab of Electronics. They reported their discoveries in the magazine Science in June of 2008.
Thanks to the MIT Solar Concentrator invented by Dr. Baldo and his team, solar powered windows will be even cheaper and will be able to sell back more energy to the grid within the next three year.
