Scooters

Scooters represent a very large and established market, with over 11 million scooters in Taiwan and 23 million in China. While scooters are convenient transportation vehicles for crowded cities such as Beijing and Taipei, they are a notorious source of pollution.

• According to CALSTART, the pollution from a single scooter can equal that of 8 automobiles.
• Shanghai has barred gasoline scooters from the city starting in 2002. In Bangkok, 25% of ferry commuters suffer from CO poisoning due to air quality issues. 70% of dogs were found to suffer from smoker's lung
• In some parts of Asia, it is common to see riders covering their mouths and noses in order to reduce the inhalation of fumes and particulates.

While companies and governments recognize that electric scooters solve the pollution issue, conventional lead acid batteries permit very limited range of travel before recharging is required. This is prohibitive for most commuters. Furthermore, multilevel housing complexes and conventional utility infrastructure do not readily accommodate the need for recharging.

The answer to this Transportation dilemma is the eVionyx RPC, a refuelable, high-energy technology that provides the convenience of long distance driving without the need to recharge or refuel.
