\"B<\/a>This week we learnt of a remarkable new material transparent wood. Two groups at the University of Maryland and the KTH institute of Technology in Sweden have developed a see through wood.\u00a0 Not only that but it can store and release heat.\u00a0 The researchers have achieved this by removing the lignin.\u00a0 This absorbs visible light and is achieved by boiling the wood in a mixture of sodium hydroxide and sodium sulphite for some hours.\u00a0 Adding hydrogen peroxide completes the process.\u00a0 Than an epoxy compound is added to occupy the space liberated by the lignin.\u00a0 Finally by adding glycol you can give its insulating heat storage capabilities.\u00a0\u00a0 When the now transparent wood warms the glycol warms absorbing the energy.\u00a0 When it cools the glycol freezes again, liberating the heat energy.\u00a0 Different glycols melt at different temperatures so you can easily adapt the material to a particular application.\u00a0 Its also stronger than plastic.\u00a0 There is talk of electronic applications and even producing solar cells.<\/p>\n

The advantages are that by using it you are trying up carbon in structures that may be used for many years, acting as a much needed carbon store. \u00a0 The material also reduces our oil dependency.\u00a0 The disadvantage is that the process is still oil dependent unless the chemicals can be made by bio-refining.\u00a0 In addition 100g absorbs as much heat as a 1W bulb uses in one hour.\u00a0 So we are not talking about huge amounts here of energy storage in my view.\u00a0 Nevertheless this is a fascinating idea that could find widespread application.<\/p>\n
