As soon as I got there, I measured how long half the basketball court was.
After that, I started my experiment. The first part of the experiment was easy because the solar panel was faced directly at the sun. I timed the speed of the car using a stopwatch. After timing it, I recorded the speed of the car in a notebook after each attempt. It was somewhat annoying when the car begun to stop. It stopped because the solar panel was blocked from the sun.
Thus, this difficulty was the part of the project that took the longest to complete. It stopped at 15 feet five times during the experiment. I took pictures and videoed the experiment during the entire process of my project. If I could change anything in my project to improve it, it would be to change the gears on the solar powered car. Solar ships can refer to solar powered airships or hybrid airships.
There is considerable military interest in unmanned aerial vehicles UAVs ; solar power would enable these to stay aloft for months, becoming a much cheaper means of doing some tasks done today by satellites. In September , the first successful flight for 48h under constant power of a UAV was reported.
Many demonstration solar aircraft have been built, some of the best known by AeroVironment.
An Australian-based company is working on a project to develop an air crane called the SkyLifter, a "vertical pick-up and delivery aircraft" being capable of lifting up to tons. A Canadian start-up, Solar Ship Inc, is developing solar powered hybrid airships that can run on solar power alone. The idea is to create a viable platform that can travel anywhere in the world delivering cold medical supplies and other necessitates to locations in Africa and Northern Canada without needing any kind of fuel or infrastructure.
The hope is that technology developments in solar cells and the large surface area provided by the hybrid airship are enough to make a practical solar powered aircraft. Some key features of the Solarship are that it can fly on aerodynamic lift alone without any lifting gas, [ failed verification ] and the solar cells along with the large volume of the envelope allow the hybrid airship to be reconfigured into a mobile shelter that can recharge batteries and other equipment.
The GravityPlane requires a large size in order to obtain a large enough volume-to-weight ratio to support this wing structure, and no example has yet been built. It does however consume power at the points where it changes its buoyancy between positive and negative values.
Hunt claim that this can nevertheless improve the energy efficiency of the craft, similar to the improved energy efficiency of underwater gliders over conventional methods of propulsion. The conventional approach to this requirement is the use of solar panels in a solar-powered aircraft. Hunt has proposed two alternative approaches. One is to use a wind turbine and harvest energy from the airflow generated by the gliding motion, the other is a thermal cycle to extract energy from the differences in air temperature at different altitudes.
Solar energy is often used to supply power for satellites and spacecraft operating in the inner solar system since it can supply energy for a long time without excess fuel mass. A Communications satellite contains multiple radio transmitters which operate continually during its life. It would be uneconomic to operate such a vehicle which may be on-orbit for years from primary batteries or fuel cells , and refuelling in orbit is not practical.
Solar power is not generally used to adjust the satellite's position, however, and the useful life of a communications satellite will be limited by the on-board station-keeping fuel supply. A few spacecraft operating within the orbit of Mars have used solar power as an energy source for their propulsion system. All current solar powered spacecraft use solar panels in conjunction with electric propulsion , typically ion drives as this gives a very high exhaust velocity, and reduces the propellant over that of a rocket by more than a factor of ten.
Since propellant is usually the biggest mass on many spacecraft, this reduces launch costs. Other proposals for solar spacecraft include solar thermal heating of propellant, typically hydrogen or sometimes water is proposed. An electrodynamic tether can be used to change a satellite's orientation or adjust its orbit.
Another concept for solar propulsion in space is the light sail ; this doesn't require conversion of light to electrical energy, instead relying directly on the tiny but persistent radiation pressure of light.
Perhaps the most successful solar-propelled vehicles have been the "rovers" used to explore surfaces of the Moon and Mars. The Lunokhod programme and the Mars Pathfinder used solar power to propel remote controlled vehicles. The operating life of these rovers far exceeded the limits of endurance that would have been imposed, had they been operated on conventional fuels. A Swiss project, called "Solartaxi", has circumnavigated the world.
According to initiator and tour director Louis Palmer , the car in mass production could be produced for Euro. Solartaxi has toured the World from July till December to show that solutions to stop global warming are available and to encourage people in pursuing alternatives to fossil fuel. Solar Electrical Vehicles  is adding convex solar cells to the roof of hybrid electric vehicles. An interesting variant of the electric vehicle is the triple hybrid vehicle—the PHEV that has solar panels as well to assist.
The Toyota Prius model has an option to mount solar panels on the roof. They power a ventilation system while parked to help provide cooling. Due to the limited area available on each vehicle either speed or range or both are limited when used for motive power. From Wikipedia, the free encyclopedia.

May 13, The human intervention is given through the operation of a pedal mechanism arranged in the front of the vehicle that activates a three-phase brushless generator, acting as a complementary energy contributor.
This is a Km race across the Atacama Desert in Chile, South America, which constitutes an assigned space in order that the Latin- American countries could show the advances in photovoltaic powered vehicles. The rest of the paper is structured as follows: Section 2 focuses on the main parts of the vehicle design.
Section 3 deals with the experimental results. Finally, conclusions are presented in Section 4. This is a vehicle with a hybrid system based on photovoltaic solar energy as main electricity source, and complemented by the contribution of human energy. The design was conceived from a point of view of a high-efficiency, lightweight and stable transport, with reduced costs, and zero emission, in its operation and in the obtaining of the energy.
General Design The solar vehicle was made with a structure of three wheels, in the shape of an inverted tricycle, for only one rider in recumbent position. The high-efficiency electric traction is achieved by a 48V — 2kW brushless in-wheel motor. Besides, it has an accommodation for the battery behind the seat, and a rear-mounted structure for accommodating electronics and controllers. The general parts of the vehicle are depicted in Figure 1.
Fig ure 1. Energy Contributions The solar vehicle combines the use of electric energy from three different sources: a photovoltaic solar energy, b energy obtained through human contribution, and c batteries.
The block diagram in Figure 2 depicts the energy systems that constitute the base of the solar vehicle, jointly with the accumulator of these energies. Figure 2. Block diagram of the energy systems Thus, it is possible to pick up the highest energy of the direct radiation depending on the incidence angle. Figure 2 also shows the converter, the speed control and regenerative braking module, for recouping some degree of energy during stopping, and the in-wheel electric motor.
The Future of Cars Could Be Solar - Renewable Energy World
The physical capacities of the vehicle rider are used for a complementary energy contribution. In this sense, the rider operates a pedal mechanism in recumbent position arranged in the front of the vehicle that activates a three-phase brushless generator, acting as an energy contributor. A three-phase rectifier was implemented for such a purpose. The batteries constitute the storage system of the electric energy and contribution when the electric motor requirements have a power request greater than the input.
The battery pack has an intelligent charge-discharge system called Battery Management System BMS that monitors the voltage of each cell, protecting it against overloads and charge imbalances, thus ensuring the capacity of the entire pack at different temperatures and its working life. The consulted bibliography allows analysing some values that quantify the power that a human being can supply without suffering physical damage.
Several factors such as temperature, pressure, altitude, and humidity have an important influence. Considering this factors, a human being of a normal physical constitution can pedal for several hours without suffering fatigue, and a rapid recovery is possible with a constant pedaling equivalent to approximately 75W. However, the bicycle rider can realize a work of three or four times more than the aforementioned value to reach approximately W in very short periods of time.
