The Rafflesia arnoldii is a parasitic plant genus Rafflesia , found in the rainforests of Indonesia (mainly in Sumatra and Borneo ) and in the jungles of Southeast Asia, developing the world’s largest flower. It was discovered in Sumatra in 1818 by Thomas Stamford Raffles and Joseph Arnold.
- The flowers can reach up to three feet in diameter and can weigh up to 11 kilograms, thus becoming the largest in the world. These fleshy flowers reddish or orange and five lobes that remain open between five and seven days. As with other plants with large blooms, they only occur every few years.
- The flowers, which emit a strong foul odor (similar to rotten meat), are capable of emitting heat. It is believed that both mechanisms are used to mimic the heat and the smell of a dead animal and attract the attention of carrion flies, which are insects that pollinate it.
- The plant has no leaves, shoots and roots (his only visible flower) and therefore does not perform photosynthesis .
- It is a parasitic plant trees, grow on its roots, from where it obtains nutrients.
- Their vegetative organs are reduced to a cellular network of fibers that are mostly between the tissues of the host plant or forming a body called rhizomatoide twisted underground.
To extract only 0.01 ounces of gold, mining companies need to:
- Remove and destroy a ton of ground.
A gold ring only (under 28 grams) yields:
- 3 tons of rock (3000 kg) 20 tons of debris left.
- Every kilo of gold consumed 380,000 liters of pure water.
Other cultures do it with wood rings, tattoos finger rings, stainless steel (for more abundant in nature and pollute less) …
However, there is one big fat problem: the sun! When it’s dark out, oftentimes the places I’d really like to have a little extra light are just the spots you can’t leave a sun jar due to lack of direct exposure to sunl
ight.The obvious solution to this dilemma is to separate the solar panel from the sun jar. I extrapolated this a bit further and realized that the only thing you actually need in the jar is the LED, and since you don’t have to cram all the other electronics in there, you don’t have to stay with the classic sun jar shape.With this in mind, I combed craigslist for some suitably shaped glass blocks, went to Home Depot for the appropriate solar light, stocked up on speaker wire and came up with the Solar Powered Walkway!
