Tanzanian designer Walter Robert has developed Renault Runner, a future taxi system that maximizes the free energy, solar power.
It is also a city car that saves space by conjoining to each other and forming a train.
Designed by Tracy Subisak, Donn Koh & Herlinda, reNew Solar Powered Charger is another type of battery charger for your re-chargeable batteries. It is simple to use to harness the power of the sun, just simply attached to windows via suction cup. It looks like the neat decorative frame that hangs on your window or sitting pretty on the table. Toss the battery in the top portion of back frame, into the charging pocket protector, and when it’s all fully charged, pluck it out from the bottom of the frame.
Executive Summary about Solar Technology by Philip Richards
In the business of solar energy, the U.S. has not been the biggest buyer of solar power. While the U.S. does quite well exporting solar panels and solar technology, there are many Americans who still find the cost of panels very prohibitive. As the price of solar energy decreases, Europe has had a much higher demand for solar power than anywhere else in the world. Many European universities and campuses have rebuilt their dorms to run off solar energy. Most water heaters in Europe are solar-powered, even if the home doesn’t have a full solar panel system.
In Europe, it’s not just small residential power systems that are leading the way in solar energy dependence. Specifically, Italy, Greece and the Czech Republic are the newest customers of solar power systems. These countries have begun to purchase so much solar energy that their borders have seen changes in tariffs for solar panels. Japan, who’s also been at the forefront of solar panel imports, has picked up solar panel buying as the cost of gas and electricity rises. There are entire neighborhoods in Japan outfitted with residential solar power panels. For example, the neighborhood of Iwaki New Town has about 46 homes outfitted with full private solar power panels. Japan also uses solar energy in surprising places. Japan is the only country to power most of its vending machines with solar energy. Sharp, one of the largest solar panel producing companies in Japan estimates that by 2010, Japan will produce 4.8 million kWh of solar energy.
The Race For New Solar Technology Is On
Executive Summary about Solar Technology by Winifred Churchill
Companies around the world are beginning to seriously consider the POWER of solar power.
One criticism of solar energy is that it cannot be relied upon for a steady supply of energy, but there are projects underway which are addressing that issue. In short, solar technology is going the way of the computer industry or cell phones. Now you get the same functionality available in personal computers on tiny cell phones. The new silicon cells for solar panels may bring a similar revolution to solar power making it a reliable, clean source of energy.

Executive Summary about Solar House by Ernest Jarquio
Environmentalists rejoice! What is this new technology that will help save the earth? Why, solar house plans of course.
What Are Solar House Plans?
Well, the new phase in home planning is the plan for a sun-powered home.
Environmentally-Friendly Materials
The designer begins by drawing out the floor plan, planing to use recycled materials, eco-friendly building supplies and Energy-Star electrical outlets. For instance, the concrete slab flooring stores solar heat during the sunny days, then releases it at night, keeping the house warm.
Insulation
The designer uses only eco-friendly items for these tasks, such as recycled wood and green material for the insulation. After all this is planned, they continue onward to Energy-Star appliances and other electronic devices.
Solar Panels
The other panels installed are the thermal water heaters, which provide hot water constantly for the entire home. This hot water is often more reliable than a traditional hot water heater, supplying plenty of heat for the laundry, kitchen and bath.
How to Plan Your House for the Sun
Executive Summary about Solar House by Naomi Kendell
Every house will gain heat throughout the day as the sun shines through its windows.
And during the night as the temperature drops, this same house will lose heat to the outside through its walls, windows and roof.
1. Orientation.
By facing your house to the south (in the northern hemisphere) you will gain the rays of the winter sun. Afternoon sun comes from the west, so rooms like the dining room and living room can be placed on this orientation. The southwest corner of the house will be the sunniest – winter and afternoon sun.
On the northern side of your house, place service rooms.
2. Window Sizing
Out of all the materials your house is made of, windows lose the most heat. There is a balance here, because windows allow sunlight into your house. However even triple glazed glass allows more heat to escape than a well insulated wall.
The first is where your windows face. If you have most of your windows on the northern side, these windows will not get much sun during winter. They will be losing heat, but not gaining solar energy.
There is an optimal ratio of windows:wall for every climate. For instance in temperate climates, a window to wall ration could be: 30% window area to 70% wall area. The other ratio is in windows and orientation.
3. Materials
For instance, highly insulated walls will keep the heat inside your house. When analyzing your heat loss through your windows, you can gain some leeway through insulation. This air forms and insulating layer, slowing down heat loss.
Another way to use materials in your solar house plan is to take advantage of heat storage. It is radiating heat. The floor is insulated underneath to prevent heat loss. A well designed thermal heat sink will stay warm all night long.
4. Shading
Shading is an important part of the solar house plan. This is important not only for heat gains, but for preventing heat gains. In temperate climates as well, shading can be used to keep summer sun out and let winter sun in.
Using our orientation principle: your house is facing south. During the winter the sun angles low and reaches far into the house. This same shading will allow winter sun into your house.
Your latitude effects the angle of the winter sun. In conclusion – solar house plans are a great way to design houses that are warm and comfortable to live in, and save you money off your heating and air conditioning bill.
Using Orientation, Window Placement, Materials and Shading, you can design a house that responds to its environment and creates its own micro-climate of comfort.
