Further down on this page there is also an article about blimp or zepelliner technology. You also find an article about the most reasonable production and use of nuclear power.
Good online hobby product shops
A good general hobby store with all kind of RC models - Wireless models of aircrafts cars and boats. Electronic sets, telescopes, computers and a lot more. Models in all size and prize cathegories, and suitable for all ages. Electric driven models that suit for indoor and outdoor use, and extreme speedy gas driven models for the advanced modeller. In addition to rc models you find all other kind of items like airsoft guns, electronic kits and components, science kits and a lot more. Through this link you are first presented the offer of the day, but from there you can go to the whole store.
Another good general hobby store - Also this store has all kind of hobby items, but partly other fabricates and models.You also find several small sized electric vehicles that children can drive in here, like cars and scooters.
Nitro driven and electric redcats - Redcats are speedy and rough model cars for rally use that can handle challenging terrains

About the technology of blimps, zepelliners and other airships
A blimp or zepelliner, also called "airship" is basically a balloon with motor and propelling technology, stearing technology and devices to controll the volume of gas so that it can lift or descend.
Traditionally a zepelliner has an elongated shape, with a gondol at the underside and with motors and propellers attached some places along the underside.
Blimps can be made soft, so that they only gain shape and rigidity from the gas pressure inside, semi-soft with a rigid scheleton and soft walls, or totally rigid with both a scheleton and rigid walls.
The motors are traditionally piston engine motors, but more modern variants use turbine motors, and the propelling devices are usually traditional propellers.
The lifting happens because the gas inside the ballon is lighter than air, and then the updrift will be greater than the weight. A gas traditionally used was hydrogen, because this is very light and very effective and also cheap. But due to fire hazard hydrogen has gone out of use. The gas used nowadays is mostly the inert gas helium.
To give more uprdift so that the vehicle can ascend, more gas is let into the balloon part from a container where it is in a comprimated state. To decrease the updrift so that it can descend, gas are pumped and prezurized from the ballon space back into the container.
The stearing is traditionally accomplished with rudders at the rear end, but more modern concepts also use propellars that can be directed towards several directions.
Zepelliners have for a long time been out of fashion, but in the last years this technology has again gained interest from both the governmental fields and the commersial market.
Blimps can theoretically be made to lift enormous weights. Blimps can also be made to hover over an area for days, weeks or months and this is an interesting property for surveillance of areas. Governments plan to use very high-hovering blimps to surveil large areas, and let these be propelled by energy gained with solar cell panels covering the whole balloon part.
Still-going blimps are also very suited for watching of animal life and for seightseeing tours over an area.
What is the Most Economical and Environmentally Reasonable Use of Nuclear Power Technology
The total capacity of nuclear power plants is steadily increasing throughout the globe. One reason for this increase is the steadily increased demand for energy. Another is the aim of diminishing the outlet of greenhouse gases, and a third is a probable shortage of oil and natural gas in the near future. Nuclear energy plants are also very clean, provided no incident happens, so an increased use of this type of energy may reduce the total impact on the environment from pollution.
But nuclear energy is expensive, and the production of nuclear energy implies obvious hazards for disastrous incidents. Both the cost of energy from nuclear power, the need for nuclear power capacity and the total hazard can however be brought to a minimum with a consequent economical use of this energy source.
Such an economical use can be achieved by establishing production cells containing the nuclear plant itself and units for production of other goods that use the energy produced in the power plant right away without a long transport. The electric power not used within the production cell must of course be transported to other consumers through the grid.
The central unit in such a production cell will be the power plant itself. One obvious output of the power plant is of course electric power. Another output is heat from the cooling system of the reactors which traditionally is thought out as waste and exchanged with the atmosphere or with the water in the sea, a river or a lake. The heat should however be treated as a product delivered for further utilization just like the electric power.
The exact types of production plants to be grouped around the central power station will of course vary according to the demand in the area and the demand from an export market.
One unit of the total complex that can utilize both the electric power and the heat could be a huge greenhouse establishment that is using the heated water to grow various types of crop. Nuclear production cells in cold parts of the globe can this way also help to increase the food production in cold areas and help to satisfy a steadily growing demand for food in the whole world.
The plant for production of food could be a traditional greenhouse, but it could as likely be a modern plant for production of food from algae or microorganisms.
Another unit would be a hydrogen factory, using produced electricity to generate hydrogen to be sold as vehicle fuel. As use of oil based fuel is getting steadily more problematic, hydrogen is rising as the new source of power for vehicles of all types.
In areas with lack of freshwater supply, an obvious unit could be a production plant for clean freshwater from seawater or from local sewers.
The rest of the area in the production cell could be reserved for power-demanding industry, for example metallurgic and chemical industries.
Such an integrated use of nuclear power will obviously need planning beforehand. Each country should have a total plan for all such production cells and all new nuclear power plants should be fitted into such an integrated industrial cell. Then the planning of each individual area for this use and the preparation of each area should also ideally be a task managed by the government of each country.
Then the area should be overtaken by the actual energy company and companies interested in utilizing the produced energy in ways according to the plan.
When planning and establishing such cells, one should also plan for the future where power from nuclear fission hopefully can be replaced by power produced by nuclear fusion. The area should be planned in such a way that one easily can build a new power plant designed by new principles, and the old plant taken down without interruption of the function in the total cell.
Such production cells should ideally be placed outside great populated areas. The establishment of such a production complex will however generate a new society around it where employees can live.
Such production complexes powered by a nuclear plant will of course be a huge establishment occupying a great area. On a total scale for a country it will however save land areas, since all the plants within the cell can utilize a common concentrated infrastructure.
Establishing such production cells can also reduce pollution on a national scale, since all the production units in the complex can use effective common resources for handling and recirculation of waste.
