Hydroponic gardening is gardening in water, without soil. With hydroponic gardening, you put your plants in an ideal condition for growing. It offers all the nutrients directly to their roots.
At first, you may feel surprised when hearing that plants do not need soil to grow, but sometimes, soil can be an inefficient culture medium.
Plants use up a lot of energy to develop their root systems until they are able to search the soil for nutrients and water for their survival. By offering readily available and constant nutrition, hydroponic gardening allows your plants to grow 50% faster than they usually do in soil. Besides, this system also brings about a great deal of benefits. Continue reading →
It has been hard enough to get people to recycle at all.
Too many people put too many wrong items in recycle bins. Recycling problems create expensive headaches.
The cost of convenience in careless recycling will grow significantly in the near future. It will hit household budgets like never before.
The seeds of recycling wrong started years before recycling started at all.
In my childhood, for example, we separated wet garbage from dry trash. My mother wrapped the day’s garbage in a newspaper, and I carried it out and put it in the very stinky can. My parents payed two separate companies to carry the two kinds of trash away.
In fact, our trash didn’t include paper, except the papers Mom used to wrap the garbage. I burned it in our backyard incinerator. It also didn’t include beverage containers. Milk and sodas came in glass bottles. Stores charged a deposit, so we returned the bottles to get our money back.
Then a big city politician won election by promising more convenient trash collection. Continue reading →

Do you find food labels confusing and hard to understand? Besides the required FDA label, manufacturers use various seals and badges with claims about what the food does or does not contain.
We need food to survive, and in the U.S., we have a lot of choices when it comes to the food we put in our bodies. However, not all the food we ingest is good for us.
Statistics show that more than 34% of adults over the age of 20 are overweight, and almost 34% of adults are obese. Therefore, we need to be aware of what’s in our food before we eat it.
The regulations behind food labels can be complex and confusing. Food manufacturers use this confusion and complexity to their advantage. Some try to sell you products that claim to be healthy but really aren’t. Knowing the ingredients in your food and how much a serving size is can help you maintain a healthier diet.

Perovskite crystal, CaTiO3 (Calcium, Titanium, Oxygen)
Researchers in alternative energy have been excited about perovskite solar technology for years now. They have also struggled to overcome serious challenges
A perovskite is a mineral crystal comprising calcium, titanium, and oxygen. Other minerals, technically perovskite structures, have the same structure, but different elements.
The distinction between perovskite and perovskite structure matters only in geology. The solar industry uses the terms interchangeably.
Certain perovskites have several properties that make them useful in solar applications, including superconductivity and catalytic properties.
They are incorporated into organic photovoltaic thin films, an aspect of nanotechnology. Continue reading →
Wattle Point wind farm, South Australia
Wind power has been part of the story of two different storms.
Critics of renewable energy blamed South Australia’s high penetration of wind power for a state-wide blackout in the wake of a spate of tornados. Partisan bickering about the feasibility of wind power started immediately and continues.
On the other hand, Hurricane Harvey slammed into a part of Texas with several wind farms. One continued to operate normally throughout the storm. The rest were back online within days. No one blamed wind energy for making the crisis worse.
What can we learn from the contrast? Continue reading →
Vinegar belongs in every household cleaning arsenal, but you need to beware of vinegar cleaning myths.
It’s not really a cleaner or a disinfectant. Combining it with other common natural cleaners can render it useless.
In fact, “natural cleaners” is a near-mythical phrase. No definition of “natural” has been made official. It can mean whatever the person using wants it to mean.
I mean those old-fashioned and versatile cleaners like borax, baking soda, or salt. The kind of cleaners that make such a great alternative to the heavily advertised products in the cleaning aisle. Continue reading →
