Energy Quote

The discovery of nuclear chain reactions need not bring about the destruction of mankind any more than did the discovery of matches. We only must do everything in our power to safeguard against its abuse.

LED Lighting

LEDs or Light Emitting Diodes as a light source offer benefits in terms of maintenance and safety. The typical working lifetime of a device, including the bulb, is ten years, which is much longer than the lifetimes of most other light sources. Further, LEDs fail by dimming over time, rather than the abrupt burn-out of incandescent bulbs. LEDs give off less heat than incandescent light bulbs and are less fragile than fluorescent lamps. LEDs are built inside solid cases that protect them, making them hard to break and extremely durable. Since an individual device is smaller than a centimetre in length, LED-based light sources used for illumination and outdoor signals are built using clusters of tens of devices.

LEV

A Brief Description:

Electric bikes, electric scooters are part of a whole range of Light Electric Vehicles (LEVs) that provide local point-to-point transportation. Generally designed for one person and small cargo capacity, range, speed, and cost of most electric bikes, electric scooters or other light electric vehicles are moderate. For most of us, half of our errands and trips are less than 10 miles - within the range of most LEVs. Clean, quiet, and efficient are the main attributes of light electric vehicles.
