Fuel Hope

This modern world we humans live in depends a lot inenergy. We need energy to move, to make the things we eat, the cloth, the lifestyle, to power up everything. Basically, without energy the world stops. Today, 90% of the energy comes from oil, which isa non renewable resource and it could end in any moment leaving humanity into nothing. That is the reason why we need to start now looking for alternatives to this oil, scientists and researcherspresent here, maybe a solution to this problem.
The other " solutions " like the big fans, wind power, sun power all have a big negative part, which is : first, the amount of those resources you needto completely replace oil is too much, for a family to have a system of solar panels is very expensive and doesn't even cover the house, same happens with the wind power. Today, scientists around theworld are still working on different methods to provide us with the perfect replacement for oil, just a week ago researchers at Bio Architecture Lab and the University of Washington in Seattle havenow taken the first step to exploit the natural advantages of seaweed, using seaweed as a biofuel. Biofuel have always been an option aside wind and solar power, it's also the easiest to manage sinceit's an oil like fuel. The thing with biofuel is that is hard to find a crop that produces enough ethanol also "Another major hurdle for widespread adoption of biofuels is the challenge of growingenough crops to meet demand, something skeptics say might well require converting just about all of the world’s remaining forests and open spaces over to agricultural land." says enviroment.about.comSeaweed is the ideal plant for biofuel use, different from other crops that have been used as biofuel plants like corn, Brown seaweed grows fast, is chock full of sugars to turn into biofuel and...
