An Efficient Hydrogen-Hybride Bike (Hy-Cycle) Developed

If you want to clean up the environment get a bike. Not just any bike though: you need a Hy-Cycle with pedal power assisted by hydrogen. A team of developers at the School of Chemical Engineering led by Associate Professor Kondo-Francois Aguey-Zinsou has put a lot of work into the new bicycle.

The main problems in the past has been storage and cost. Hydrogen is now safely stored in hybride, a stable metal. This "compound" is then secured in a canister. Hydrogen is fed into a fuel cells that charges a lithium battery. The battery range is 125 kilometers at a cost of $2.00. This distance is sufficient for a day's use on one charge.

Major cities across the world have already established bicycle pools where people can collect a bicycle, ride it to their destination and leave it at the nearest bike station. It would not be difficult to hire out the new powered Hy-Cycles at a small fee alongside ordinary bicycles.

Improvements are already on the way. The current storage system holds 100 liters of hydrogen in one kilogram of hybride. A similar amount of hydrogen can be stored in 50 grams of borohybrides. A new technique nearly perfected. It seems the barrier is not investment or capability it is human culture itself.

Men Choose Degrees That Provide Good Incomes

There is a reason more women are not in high income occupations. Let's face it the truth is the truth - most women do not have a mathematical mind. It is based on evolution where women developed social skills to collect berries and tubers. Men on the other hand had to hunt dangerous large animals and this needed calculating brains.

Even today the sexes express their differences. More men choose university degrees in maths, engineering, technology and science. This where big money is earned. Humanities degrees especially the common or garden Bachelor of Arts will leave you in the unemployment line.

Australians generally persist in studying for a BA despite all the statistics showing how weak this honor is. They know it is easy to get, but the easy way is not the best and more rational way.

Just choosing a non-humanities degree is not that easy for females. A few have extremely good mathematical skills. They are at least equal to men. Most do not have the mental precondition to do well in maths at school.

As an example, a quarter of men choose engineering degrees. Only 3.7 per cent of females choose this course of study. The only "maths" area of science studied by more women than men is veterinary science.

Breakthrough in Artifical Intelligence

For a century now people have been assuming that robots will arrive and become commonplace in the home.  Manufacturing has its industrial robots but helping robots in the home have not become reality.  The problem is not so much being able to construct the physical aspects of a robot, it is the intelligence, the "brain", that is the big issue.

By doing 25,000 runs on a computer to build up experience, it was found that biological intelligence was structure into a network of modules.  This is a breakthrough finding for artificial intelligence.  Modules means alternatives can be chosen to meet a problem.  This is what makes humans and animals so difficult to understand.

Apparently, all things evolve via modules.  Such networks have not solely appeared out of intellectual necessity.  Modules can be joined together with shorter network connections, using less to make more.  Evolution is not wasteful. 

In the computer simulation, once a cost for network connections was added modules were formed.  Without the cost variable, there was no order to the simulation.  In animals modules are seen in the brain, metabolic networks, gene regulation, protein-protein interaction and the vascular system.  Even the Internet is modular.
