Q Drum is a portable water container developed by South African engineer Piet Hendrikse which allows people in developing countries to easily carry over 13 gallons of water. Water is heavy. The average person can lug up to about 4 gallons (30 pounds) of water. In rural areas of the developing world, many women and children must make multiple trips each day to a river, well, borehole or other water source to collect water for their families. The Q Drum saves them time by allowing them to transport more water in a single trip. It also helps prevent debilitating back and neck injuries caused by carrying heavy loads.
The drum can also transport other things such as foodstuffs and clothes. If some soap and water are added, the drum becomes a portable, manual clothes washing machine. Outside of the developing world, it can be useful in bringing water to those in need following natural disasters.
Q Drum lets people roll a durable donut container along rough terrain. The container has a hole through the middle where a rope is tied that allows even a small boy to pull a fully loaded tank. The linear low-density polyethylene (LLDPE) means the drum is almost indestructible, lasts 8 years, and has no removable handles or other metal attachments. The rope if lost can be replaced by a leather thong, woven plant, or any other rope-like material.
The impact of gravity light can be 1.2 billion people (~20% of the world).
UK firm Deciwatt has set out to solve one of the world's pressing problems -- lack of access to electricity -- by a new device called the GravityLight. About 20% of the world population has no access to what's now considered a basic necessity. With a rising population, especially in developing countries, unfortunately, this percentage is expected to remain the same for the next 20 years. Without cost-effective alternatives, most people have to rely on kerosene lamp. A kerosene lamp is a bottle filled with a fuel and lighting with a wick at the top. Kerosene lamps have four major disadvantages:
Breathing kerosene fumes everyday is equivalent to smoking 40 cigarettes a day.
The cost of kerosene is high relative to the income of the poorest. Poor households often spend at least 10% of their income on this power source -- as much as $36 billion according to the World Bank.
Kerosene lamps are dangerous since the light comes from an open fire. In India alone, 1.5 million people have been burned by kerosene lamps.
The world suffers from carbon dioxide pollution caused by kerosene lamps which is estimated to be about 3%.
A company called Deciwatt proposed a solution via a prototype device called the GravityLight. Unlike other power sources, the device invented by UK industrial designers Jim Reeves and Martin Riddiford requires no battery, sunlight, or wind. Its energy source is based on fundamental physics -- gravity. Seconds is all that's needed to lift the 12 kg bag which powers the device. As the weight slowly falls, GravityLight can produce 20 minutes of light.
Riddiford, now 60, a cofounder of London-based product design firm Therefore and now a cofounder of Deciwatt, got the idea six years ago after leaving a meeting with a charity interested in solar tech. “I just sort of had this vision of, well, why can’t you use human power and store it as potential energy rather than in a battery,” he says. Riddiford has a record for innovative devices including the Brinlock Abacus calculator which was the first calculator with number-shaped buttons. He stated that he regrets not having done charitable work overseas in his youth and hopes to make up for it with his light.
In 2013, Deciwatt raised £265,000 on crowdfunding platform Indiegogo to fund the tooling, manufacture and distribution of its first 1,000 lights. More recently, in 2015, Deciwatt won the Shell Springboard program, which supports young entrepreneurs with innovative low-carbon ideas. It received £150,000 to help develop the product further and expand into new markets, beating 150 other applicants to take the prize.
Deciwatt says the GravityLight can cost as low as $10 for the owner. The actual price varies across different markets. The price will reduce in the future as mass manufacturing and the increasing efficiency of LEDs drive the cost down. Even with current prices, the owner can see a return on investment after just three months.
