Summer at the Beach

In 2020, I hope to still be celebrating my christmas holidays by the beach as I have done for the last 20 odd years. The very hot summer days during this time means power consumption in the city is at its very peak. Most houses have at least one, and often more than one air conditioner in operation. There should be a way that we could capture the heat of the day to power our air conditioners inside the home. On the roof we should see a system where possibly there is a solar panel which is used… Continue

Human Powered computers

One thing that practically every business is using these days is computers. Especially in the big cities where many office workers spend their days inside an office tower in front of a computer. These office blocks are huge consumers of power. From the computers, to the printers, phone lines, lights, coffee machines all the way down to the beer fridges huge amounts of power is being consumed by administrative businesses that give very little back in the way of power generation. If we could…

Wind Energy


This website is dedicated to sustainable energy ideas in Australia. One of the biggest sustainable energy projects near where I live in Western Australia is wind-farms. On a holiday island off perth called rottnest, they have now put up a wind-turbine to power the island.

Learn about food security

There appears to be two sides to food security - physical and economic. In the local Grahamstown community where I currently am staying, i think the economic side of food security is more of a struggle than the food actually existing. Here there is plenty of good quality food in the shops and lots of variety for what you can buy.,The main problem people face though is not having enough money to buy the goods. This is in contrast to Zimbabwe, where in late 2008 before the country was dollarised… Continue

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

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. In addition the Stinging Nettle consists…See More

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

public servants

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.
