Solar Sand Manufacturing


Markus Kayser - Solar Sinter Project from Markus Kayser on Vimeo.
In this experiment sunlight and sand are used as raw energy and material to produce glass objects using a 3D printing process, that combines natural energy and material with high-tech production technology.

Thorium as energy source


India hopes it has the answer: thorium, a naturally occurring radioactive element, four times more abundant than uranium in the earth’s crust. 
 The pro-thorium lobby claim a single tonne of thorium burned in a molten salt reactor (MSR) – typically a liquid fluoride thorium reactor (LFTR) – which has liquid rather than solid fuel, can produce one gigawatt of electricity. A traditional pressurised water reactor (PWR) would need to burn 250 tonnes of uranium to produce the same amount of energy.

Some people think that Liquid Thorium reactors could provide energy without carbon emissions.








Water Lightning

Innovative lightning solution for poor. However, it provides lightning only when Sun shines into it.

Green IT

Governments around the world are wrestling with the challenge of how to reduce carbon dioxide emissions. The current preferred approaches are to impose carbon taxes and implement various forms of cap and trade, which effectively is a hidden tax. However another approach to help reduce carbon emission is to “reward” those directly who reduce their carbon footprint. The concept is very similar to the "Cap and Dividend" except rather than providing a tax credit, the consumer is offered a variety of free low carbon services and products. One possible reward system is to provide homeowners with free fiber to the home or free wireless products and other electronic services such as ebooks and eMovies if they agree to pay a premium on their energy consumption which will encourage them to reduce emissions by turning down the thermostat or using public transportation. Not only does the consumer benefit, but this business model also provides new revenue opportunities for network operators, optical equipment manufacturers, and eCommerce application providers.
