20,000 Volts Under The Sea
This is an undeveloped idea that may or may not be practical depending on the power output, but either way, hopefully it will spark some discussion and/or new ideas.
So my thought is that many power systems are run by what is known as a "gradient." An example of this is geothermal energy which utilizes the temperature difference (aka the temp gradient) present between the surface of the planet and the earth beneath the surface. Water or some other fluid is pumped into the…

Solar Powered Clothing on the Rack Soon
Here is something to keep an eye on: solar powered clothing
Okay, okay, this one is bit weird, but the advance of bendable solar panels does help one thing of ways to put the solar panels onto/into clothing so that we can generate power. Is it inexpensive -- definitely not.
The Power Shift and Saving Electricity
I was thinking about all power usages we are using and how can I reduce this usage and save energy.
When I was a child it was all so new using electricity that commercial were saying “Use more Electricity…

Power myself more sustainable
I decided not to look at my direct power use but actually at the indirect power use through food that I use to power myself. I can't even imagine how much power it costs to transport food all over the world or to grow it in greenhouses. Or the unsustainability of meat-eating (1 kilo of meet needs 10 kilo of plants, in terms of how much an animal has to eat, not even naming the waste production of animals).
So I will start to eat meat just once a week (still once a week for…

A New Reason to Walk
http://www.alternative-energy-news.info/human-power-is-the-future/
Apparently, engineers at Princeton are developing a new flexible sensor that stores the mechanical energy from normal human activities such as walking and dancing. It's a tiny thing that can be placed on the bottom of one's shoe in such a way as to be bent and rounded with every step, so that just walking or running can produce the…

Sorry, my battery died
Looking around my little desk, 4 different little electronic devices stare up at me: a cell phone, digital camera and two music players. I love these little gadgets and almost everyone I know also have their own arsenal of personal electronic devices. The downside is always how much juice these things use up! How many times have you called someone on their cell and left a message expecting them to get back to you in due time, only to hear back from them more than a day later saying their… Continue

Noise, Anyone?
Sound energy is generally very small in scope, so is not often thought of as an alternate energy source, but hopefully this won't sound too terribly silly. After all, my proposal is to power something very small with the sound from a highway. Sound energy could conceivably be used to turn the noise from the road to something helpful instead of pollution. There are people who live near airports and busy roads that could capture sound energy from sensors... hypothetically. The energy captured…

Sahara Solar Plant
A few years ago, an australian miner told me over a few beers that he did not like being a miner and that he just 'did it for the money'. That was kind of funny, because this fellow looked like he was built to be either a miner or a professional wrestler (he later told me his real passion lay with writing short stories - which is tough if you spend your time working in a copper mine).
Because I knew Australia to be a very coal-dependent country, the conversation quickly turned to the… Continue

Alternative Sources of Energy
I found several interesting projects or companies, but I'm still doing research. There's just so much out there to learn! Here are a few that I wanted to highlight first:
Voltree
Voltree Power has created a Bioenergy Harvester that changes plant energy into electricity. It is mostly used in "mesh networks," where small amounts of power are needed over very large… Continue

My love hate relationship with Bonneville dam
living in Portland most of my power comes from the hydro electric dams that line the Columbia river. these dams have destroyed fish habitat and making salmon fry easy targets for predators. when i was in kindergarten i had the obvious solution: "we have to blow up the lights!" i said. when asked why i said: "because it kills salmon!"
Bonneville dam was built by the army Corp of Engineers during the new deal along with several other dams. among the many people provided work by this… Continue

Kite energy
Wind is something that can be found everywhere. Unlike water, fire, or oil; wind is even in places where it is not considered to be windy. Up, higher than the wind turbines go the wind currents are present and power full Saul Griffith has started to look into and designing kites that could be use to harness the energy from these currents. This is teh TED video where he explaines this http://www.youtube.com/watch?v=LguEk06Wb-U

From rice husks to electricity, a good (and profitable) idea.
I chose Husk Power System (http://huskpowersystems.com/home.htm) which is a company that transforms rice husks to electricity in India.
Chip Ransler and Manoj Sinha are key principals behind HPS, a for-profit company. The organization utilizes this technology in the production and operation of 35-100 kW mini power plants that deliver pay-for-use electricity to un-electrified villages in India’s “Rice…

Fourth of July on the Lake
This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More
Stinging Nettle
In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein.

It is 7'oclock, I was late home from work due to an assignment that i wanted to get ahead on. By the time I get home I am feeling extremley tired and I cannot be bothered to make a proper meal.

Future
FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
