I needed something to keep the rain off the lantern while the panel was charging the battery. So I bought a Sterilite 20 quart (19 liter) plastic tub. The lantern fits well in the tub, with room to spare. The solar panel sits right on the recessed lid of the tub, and the wind hasn't blown it off so far. And while the lid fits snugly on the tub, there is a small gap on the edge for the cord to come out without getting pinched.

The tub works great. The one drawback is that the tub is the perfect size for perching, and when The Bean sits on the panel, the cat gets charged but the lantern battery doesn't.

Appropriate Technology

This solar lantern is a good example of appropriate technology. Recharging the battery pack right in the unit using solar energy is a great idea. It eliminates wasteful throw-away batteries, and the need for a separate battery charger.

The Solaris solar lantern with PV costs US$169 and is available from Light Corporation. The whole unit is portable and ruggedly built, and is useful for emergencies and everyday use, in homes and RVs, in boats and treehouses. Come to think of it, this lantern would be useful just about anywhere on the planet.

epal was a forbidden land until the 1940s. As it opened to the outside world, tourists came pouring in to explore the untrodden land, virgin forests, rivers, lakes, and the majestic Himalayas. In the '80s, the symptoms of haphazard urban growth had begun to appear in Kathmandu, the capital of the country and entry gate to Nepal for tourists. Air pollution and traffic congestion from an increasing number of mostly old and worn out vehicles became everyday concerns of people in the Kathmandu valley.

Safa Tempo

Concerned authorities were grappling with these problems, and how to amend the tarnished image of Kathmandu in the international community. Then electric three wheelers—popularly known as safa tempos—came onto the scene. The term "safa tempo" is a Nepali name for a battery operated three wheeler.

"Safa" in Nepali means "clean," since it is a zero emissions vehicle. "Tempo" is a generic name for three-wheeled vehicles.

Global Resources Institute (GRI), a U.S.-based nonprofit NGO, built their three-wheeled model of a battery operated EV in the early 1990s. No one suspected that it could become a major force of public transportation and give a breath of fresh air to Kathmandu. In 1996, the GRI project ended and the private sector strode into the EV industry. Between then and now, the number of safa tempos on the roads has increased dramatically. This was due to government incentives and support for the EV industry, and the private sector's dogged determination to make it a financially viable venture—a feat seen nowhere else in the world. Currently, an impressive 550 safa tempos are providing public transportation.

A safa tempo is a small, three-wheeled vehicle used to provide public transportation service. Generally, low and middle income commuters use safa tempos as a means of daily transport. A few safa tempos are also being used in offices for ferrying staff, delivering mail, carrying solid wastes, and for hospital use.

The vehicle uses a 22 horsepower motor, and has a gross vehicle weight of about 1,050 kg (2,300 pounds), including one set of batteries. A safa tempo can carry

720 kg (1,600 pounds), which means twelve people including the driver. The maximum speed an empty safa tempo can attain is 40 km per hour (25 mph). The average speed with a full load of passengers is 25 km per hour (16 mph).

Cost Effective

These commercially operated electric vehicles are simple and low-cost technology in comparison to EVs operated elsewhere in the world. The cost of a safa tempo with two sets of batteries is either Rs. 505,000 (US$7,214) or Rs. 525,000 (US$7,500) depending upon the type of batteries installed. Safa tempos are assembled in Nepal, with the majority of parts coming from abroad. The chassis is from India, the motor is from England, and the batteries, DC-DC converter, speed controller, and metering come from the USA.

Two models of lead-acid batteries are being used in safa tempos in Nepal. They are Trojan T-105s and Trojan T-125s, both manufactured in California, USA. The T-105 gives a range of 55 to 60 km (34-37 miles) per charge, and the T-125 gives 65 to 70 km (40-43 miles) per charge.

Safa tempos run with twelve 6 volt batteries, for a total pack voltage of 72 volts. The cost of one set of Trojan T-105 batteries is about Rs. 60,000 (US$857), and one set of Trojan T-125 batteries is Rs. 70,000 (US$1,000). The capacity of the T-125s and T-105s for five hours of discharge is 197 and 187 ampere-hours respectively. Once the set of twelve batteries is discharged (which usually happens by noon), it is exchanged for a fully charged set of batteries at a charging station.

Private Sector Initiative

No safa tempos would be running today had the private sector not ventured courageously into this market and withstood the challenges. They played a key role in popularizing safa tempos by manufacturing the vehicles at a reasonable cost and providing associated services such as charging and maintenance in a cost-effective way. While EVs in other parts the world are far more expensive than gasoline vehicles, safa tempos are available at quite reasonable prices compared to their petrol and diesel versions.

The role of the private sector in infrastructure development for the EV industry is substantial. There are currently five EV manufacturing companies in Kathmandu, with a total production of about sixty per month. The investment capital for manufacturing came mainly from the entrepreneurs themselves, with only a small number of loans.

The operating cost of a safa tempo is Rs. 7 (approx. 10 cents) per kilometer, including depreciation cost of the batteries and vehicle, and a driver's salary. The average fare per km for a passenger is Rs. 1.25 (2 cents). A safa tempo carries a total of eleven passengers, and the average profit comes out be Rs. 6.75 (approx. 10 cents) per km. The average vehicle covers a distance of 110 to 130 km (68-81 miles) per day, so the profit per day comes to about Rs. 743-878 (approx. US$11-13) per day. The payback period is three to four years depending upon whether an entrepreneur has invested fully by himself or has borrowed from a bank.

The charging system infrastructure is also largely the result of private initiative. More than 75 percent of the chargers currently in use are manufactured in Nepal by four companies: Lotus Energy, Digitech, Everest Machinery and Electronic Complex, and Guraya. The technology of locally produced chargers ranges from manual to digital. The quality is quite comparable to those imported from abroad.

There are twenty-six charging stations located at different points along the routes. Charging stations are recording good profits. Martin Chautari (a non-profit advocacy organization) did a study, a project advocating alternative fuel vehicles (AFVs) in Nepal. It shows that twenty charging stations have been

Safa tempo—Nepal's zero emissions, three-wheeled vehicle.

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
