Indigenous-led conservation, natural law and a different future

Indigenous-led conservation, natural law and a different future

“Conservation is what we learn and observe from the natural world,” said Tyson Atleo, a hereditary chief of the Ahousaht Nation and the economic development lead of Nature United conservation organization.  “Our stories are true,” Tyson Atleo’s great-grandmother used to tell his father growing up. Tyson Atleo’s father, Ah-up-wa-eek, Shawn Atleo, is the Tyee Hawiith (head chief) of the ... »

POWER DISTRIBUTION IN NIGERIA

POWER DISTRIBUTION IN NIGERIA

The distribution grid operates mainly on 33 kV and 11 kV level, i.e. medium voltage (MV) and low voltage level (LV). The distribution network accounts for an additional 12.5% of technical losses before electricity reaches the final consumer. In the wake of the power sector privatization that took place in 2103, 11 distribution companies covering a regional grid were sold to new private owners. Not... »

How to choose the best battery for a solar energy system

How to choose the best battery for a solar energy system

Each year, it’s becoming more common to install solar batteries with solar panels. They provide significant benefits, such as energy independence and emergency backup power, but it can be difficult to know exactly what to look for when shopping for a solar battery. WHAT IS SOLAR BATTERY STORAGE Solar batteries are used to store energy that solar panels produce. The stored solar energy can then be ... »

LITHIUM-ION BATTERY TECHNOLOGY

LITHIUM-ION BATTERY TECHNOLOGY

Lithium-ion batteries have also been in the news lately. That’s because these batteries have the ability to burst into flames occasionally. It’s not very common — just two or three battery packs per million have a problem — but when it happens, it’s extreme. In some situations, the failure rate can rise, and when that happens you end up with a worldwide battery recall that can cost man... »

WHAT ARE THE SOURCES OF RENEWABLE ENERGY?

WHAT ARE THE SOURCES OF RENEWABLE ENERGY?

Estimates suggest the hypercar could go for anywhere between $2.6 and $3.9 million – but $3.2 million seems to be the magic number. Whatever the case, this machine i... »

Radiation therapy, uses and Applications

Radiation therapy, uses and Applications

Radiation is used in medicine, to generate electricity, to make food last longer, to sterilize equipment, for carbon dating of archeological finds, and many other reasons. Ionizing radiation happens when the atomic nucleus of an unstable atom decays and starts releasing ionizing particles. When these particles come into contact with organic material, such as human tissue, they will damage them if ... »

Where does radiation affect most in the body?

(1) Hair The losing of hair quickly and in clumps occurs with radiation exposure at 200 rems or higher.   (2) Brain Since brain cells do not reproduce, they won’t be damaged directly unless the exposure is 5,000 rems or greater. Like the heart, radiation kills nerve cells and small blood vessels, and can cause seizures and immediate death.   (3) Thyroid The certain body parts are m... »

Working principle of a refrigerator

Working principle of a refrigerator

The working principle of a refrigerator is basically through evaporation. To clearly understand this, we need to look at the second law of thermodynamics. The law states that if a cold object is placed next to a hot object, the cold object will become warmer and the hot object will become cooler. A refrigerator does not cool items by lowering their original temperatures; instead, an evaporating ga... »

Solar battery: the best choice for your home

Solar battery: the best choice for your home

A home battery system stores surplus solar power for later use. The solar battery extends the use of a PV-system’s generated energy and will provide free, sustainable power even when the sun is not shining and the panels don’t produce energy. Therefore, with a solar battery little to no electricity is fed into the grid while also avoiding having to buy expensive electricity from the grid later. Du... »
