There is a gym in Hong Kong where the exercise machines activate a generator that creates electricity. An average person can produce around 50 watts of electricity in an hour. (Coming across gym and exercise machines I remember what I read in the book “Five Point Someone”. In that book, a Professor defines machines as complex or simple systems designed to reduce the human effort involved in any kind of work. A bright student raises the following question. “If machines are designed to reduce human effort, what does the exercise machines in the gym do? Do they really reduce human effort?” There is a logical explanation for this. Now, I like someone reading this post to come up with it and post in the comment section.)
A Norwegian company is planning the world’s first floating wind farm – which can be placed farther out into the ocean than the traditional offshore wind farms. (But I had already come across the fact that some German company had established wind farms in the vast ocean, of course not floating. And know how the operations and maintenance engineers reach there? They use helicopters!!)
Some company is experimenting with so called “Oil 2.0” a crude oil made from the dropping of ‘industrial yeast’ along with innocuous strains of E.Coli. (Wow, E Coli had been used in some kinda medicine. Now in fuels too?!! Sound gud)
This one is ma favorite fact coz its I had read it many times thru my six years of engineering study. Piezoelectricity!! Some materials when put under change of shape or pressure, generate electricity. How sweet it would be if I could join research in this domain!!!
One way to use passive solar energy in your house is to plants trees around your house. Trees block the sun in the summer and let in the light in the winter. It’s a way to use the sun’s energy without having to deal with a solar power system.
According to treehugger.com, wind power can reduce your power bills by 90 percent!!!
