Power Generation Via Hydrogen Is Not Taking Off

It is amazing how many will see something new, then run with it to the extreme saying this will change the world. This is true for virtually all non-fossil energy producing systems, but all of them have drawbacks and none have revolutionized the power sector. The two major problems have been high cost and inconstant energy production during the 24 hour period.

Scientists have worked on hydrogen systems for decades and success seems very distant. It is not being accepted for widespread use. Actually, hydrogen is a "byproduct" of energy production. When electricity is generated by any method the excess not used at a point in time is passed through water. It splits in oxygen and hydrogen via electrolysis with the fuel being stored to be used in the future. When hydrogen is recombined with oxygen, electricity is generate. Heat from the process can also be used directly for heating purposes.

As with other environmentally friendly electricity producing methods time will tell if hydrogen is accepted for general use. Perhaps hydrogen can be made in significant quantities from solar and wind generation. It could potentially make for a hybrid system producing electricity 24 hours a day. Until now, governments have been the main source of funding for hydrogen experiments. Apparently, the private sector sees little future in it. For non-fossil energy systems to flourish it is necessary for the community to work together. Unfortunately, individualism is the norm. Perhaps this is why there is very little progress.

Can City Sanitary Systems Stand Up to Fat People?

The fattest people in the world are Americans closely followed by Australians. This is not true. Bahrain has the fattest women. Even in that country fat people are looked down upon. They have a high risk of getting many life-threatening diseases. I don't want to be rude but women in Islamic states do tend to be on the large side. Perhaps this is due to the men not wanting them to be attractive to other men. Maybe Australian wives are fat because their husbands take the same view.

New research has shown that fat people have lower activity in frontal lobes. This increases risk-taking behavior. Gambling apparently has a cause. Mass produced foods are causing behavioral change in societies. As developing countries adopt Western dietary habits their societies change as well. Preservatives and colorings are the main factors. High carbohydrate and protein diets are also detrimental. Gone are the days when women foraged for wild vegetables and berries while their men brought home meat once a week. Eating too much food definitely contributes to diabetes. This disease is rising as people eat, eat and eat.

A human being should only eat one meal a day. Many have four meals a day and eat between meals. Treat-taking is becoming the norm. When people do the weekly shopping they fill the trolleys with soft drinks, chips, chocolates and lollies. Rich, sweet deserts are popular. Your body can do without them. It is not a question of whether the health systems can stand up to this onslaught. In the long run city sanitary systems may not cope.
