Residents want better lighting

Bukit Bandaraya Residents’ Association president Datuk Mumtaz Ali is also calling for the police to erect three police beat bases in the area.

“We have called for beat bases to be set up at Lorong Maarof next to the Petronas station, Jalan Jejawi park and at the Bukit Bandaraya Community Centre. The beat bases will benefit those who are going to the park, school and community centre,” he said.

Mumtaz said that the association will help contribute funds for the beat bases.

“We would like to focus on community policing. We want to work together with the police to create a neighbourhood watch,” he said.

Mumtaz said that City Hall should look into the lighting around their neighbourhood to prevent crime in their area.

“We hope that City Hall will soon change the light bulbs to light-emitting diode (LED) bulbs, which are brighter. We would also want them to light up the back lanes,” he said.

Mumtaz reiterated that City Hall should look into the maintenance of the community centre, which is frequented by many people.

“The audio system at the main hall is not working properly and plug points in most areas of the centre are also not working. We want City Hall to look into the cracks at the tennis court which have yet to be fixed,” he said.

Resident Peggy Goh, 69, who lives in Jalan Kemaris, said the residents wanted the police to patrol the area more often. She said that there had been 10 break-ins since middle of last year.

“We want police to make their presence felt to deter crime here,” she said.

Ann Makosinski, a high school junior in Victoria, British Columbia, was trying to think of a way of harvesting untapped energy when she was inspired to make the flashlight.

She realized that the warmth generated by the human body was an overlooked energy source.

Her project objective was to create a flashlight that ran solely off the heat of the hand.

That objective was accomplished when she discovered Peltier tiles, which produce electricity when one side of the tile is heated and the other is cooled.

Makosinski realized she could use these tiles to create energy for her flashlight if she left the device hollow.

Holding the flashlight on the outside would cause the tiles to heat  up on one side while the ambient air would cool down the tile on the inside of the flashlight.

The power created by the tiles was enough to power an LED light, but it did not create enough voltage.

To troubleshoot that issue she created a circuit that would allow for transformers, upping the voltage.

It worked! The flashlight does have one issue: it works better in colder temperatures since the inside is better able to cool down comparative to the person’s body heat. More information about the program is available on the web site at www.hmhid.com.
