Gravity Light Innovates to Use Weight and Gravity to Produce Electricity

Title: Gravity Light

Duration: 2.47 minutes

Description:

Gravity Light innovates to use weight and gravity to produce electricity.

The Technical Director of Gravity Light explains and demonstrates the power of weight, lifted by a winch, and the pull of gravity in generating low cost electricity for people on low incomes in mind. Kerosene lighting is bad for health and provides poor quality lighting for family homes, where children suffer the consequences. Ideas and innovation lead the way to practical, low cost solutions, all of which will be demonstrated at “Make the Future London” festival this year.

Can you get light from a bag of rocks?

[Background music plays]

Background of pulsating musical note continues.

{Jim Reeves – voice over}

“Living in an environment lit by kerosene is really harmful to your health.”

[Animated sequence]

In a dark background, a hand holds a lighted match ready to light a kerosene candle.

{Jim Reeves – voice over}

“So you can breathe in an awful lot of noxious fumes.”

[Animated sequence]

In a dim lit living room, a family sits around a table in the light of a kerosene candle and a kerosene lamp. A wide eyed baby sucks his thumb. A boy sitting at the table doing his homework by the kerosene candle light.

Move to front of boy doing homework, nose close to book on table. His mother looks on over him.

[Animated sequence]

Close up of base of modern lamp with brand name stamped on it – GRAVITYLIGHT, and beads of light cord.

[Animated sequence]

Focus on Jim Reeves, seated, speaking in his workshop.

{Jim Reeves}

“Gravity Light seeks to give people who presently rely on kerosene for their home lighting access to power and light.”

[Background music plays]

Background of pulsating musical note continues with more notes added.

[Animated sequence]

Still Jim Reeves, seated, in close up but background comes into clearer focus to show work benches covered in electronic tools and equipment and angle-poised lamps.

{Jim Reeves}

“It relies on a lifted weight…”

[Animated sequence]

Jim Reeves demonstrating how Gravity Light works. He looks up at a suspended white lamp and pulls a yellow beaded cord.

{Jim Reeves – voice over}

“…and while that weight slowly descends, a gear train inside…”

[Animated sequence]

Close up of Jim Reeves’ hands handling gear train. Then close up of Jim Reeves’ hands showing the inside of a gear train.

{Jim Reeves – voice over}

“…turns that descending weight into electrical power, which in turn rides through…”

[Animated sequence]

Scene back to close up of Jim Reeves seated in workshop, speaking to camera.

{Jim Reeves}

“…high efficiency LEDs providing ambient light and task lighting for a dwelling.”

[Background music plays]

Background music still pulsating but becoming more a melody.

{Visual transition}

Close up of white beaded lamp cord, background out of focus. Then focus moving on to a Gravity Light packaged in a box standing on a top of a desk at the workshop.

{Jim Reeves – voice over}

“I’m Jim Reeves, technical director of Gravity Light.”

[Animated sequence]

In darkness, two hands direct a glowing light over an open book on a desk.

{Jim Reeves – voice over}

“I’m a design engineer.”

[Animated sequence]

Return to Jim Reeves seated in workshop.

{Jim Reeves}

“Innovation doesn’t happen in a vacuum. Ideas don’t just arrive. Problems arrive.”

[Animated sequence]

Reeves handling an electrical part at his workshop desk.

{Jim Reeves – voice over}

“You start out with a lot of questions…”

[Animated sequence]

Close up of Jim Reeves” face as he examines what is in his hands.

{Jim Reeves – voice over}

“…and if you’re going to be…”

[Animated sequence]

Back to Jim Reeves seated in workshop.

{Jim Reeves}

“…a successful innovator then you have to ask the rights ones. But you also need to be willing to ask the harder ones.”

[Animated sequence]

Reeves against workshop benches in focus, gesturing as he talks.

{Jim Reeves}

“Like, what are the constraints, because the constraints drive everything. The solutions come, or the innovation comes, when you’ve taken that problem apart.”

[Background music plays]

Music begins to fill out into melody.

[Animated sequence]

Close up of a pile of shiny new steel screws over a green surface.

{Jim Reeves – voice over}

“What are the physical limitations of materials?”

[Animated sequence]

Black beaded light cord over the same green surface.

{Jim Reeves – voice over}

“What is practical? What is achievable?”

[Animated sequence]

Back to close up of Jim Reeves at the workshop.

{Jim Reeves}

“What do you do if you’re not going to store power?”

[Background music plays]

Music full melody, the pulsating still discernible.

[Animated sequence]

Jim Reeves against focused background of the workshop, gesturing.

{Jim Reeves}

“You have to look at what’s abundantly available. What people already have.”

[Animated sequence]

Person in front of two computer screens on a desk, one screen showing a diagram of the Gravity Light lamp with its cords and weight.

{Jim Reeves – voice over}

“Very few products…”

[Animated sequence]

The screen showing the diagram of the lamp zooms in to show the brand name GRAVITYLIGHT

{Jim Reeves – voice over}

“…are designed with people…”

[Animated sequence]

Hands working on the internal workings of lamp, assembling it parts.

{Jim Reeves – voice over}

“…on low incomes in mind. So we went through a process of developing…”

[Animated sequence]

Close up of hands pulling white beaded cord through the internal workings of the lamp on a workbench.

{Jim Reeves – voice over}

“…a first product. And when you have that first product…”

[Animated sequence]

New scene showing a screen with a recording of the workshop wall, with electronic equipment and weights suspended from it. The recording fast forwards to show Jim Reeves climbing a ladder to check the parts of the light.

[Animated sequence]

Close up from beneath the suspended weights, sequence fat-forwarded.

{Jim Reeves – voice over}

“…that’s a vehicle for then gathering more information.”

[Background music plays]

Musical background rises into full melody.

[Animated sequence]

Back to close up of Jim Reeves talking, seated, in workshop.

{Jim Reeves}

“So with Gravity Light 1 you pick the weight up from the ground.”

[Animated sequence]

{Jim Reeves – voice over}

“We found out that…”

[Animated sequence]

Back to close up of Jim Reeves talking, seated, in workshop.

{Jim Reeves}

“…if you are a child and you’re studying then you haven’t got independence to study because you’re lifting a big heavy weight that might be too much for you.”

{Jim Reeves – voice over}

“You pull down on a cord with a couple of kilos of effort…”

[Animated sequence]

Back to close up of Jim Reeves talking, seated, in workshop
