Scientists at Cambridge University have created a way to power electrical devices using algae, in a move which could eventually mean it replacing batteries.
Researchers have used a widespread species of blue-green algae to power a microprocessor continuously for over a year using nothing but ambient light and water.
Their system has the potential to be a reliable and renewable way to power small devices in the future.
The system, comparable in size to an AA battery, contains a type of non-toxic algae called Synechocystis that naturally harvests energy from the sun through photosynthesis.
The tiny electrical current it generates then interacts with an aluminium electrode and is used to power a microprocessor.
The system is made of common, inexpensive and largely recyclable materials and the researchers believe it will enable the initiative to be replicated hundreds of thousands of times to power large numbers of small devices as part of the Internet of Things.
The Internet of Things is a vast and growing network of electronic devices — each using only a small amount of power — that collect and share real-time data via the internet.
Using low-cost computer chips and wireless networks, many billions of devices are part of the network — from smartwatches to temperature sensors in power stations.
“The growing Internet of Things needs an increasing amount of power, and we think this will have to come from systems that can generate energy, rather than simply store it like batteries,” said Professor Christopher Howe in the University of Cambridge’s Department of Biochemistry, joint senior author of the study paper.
“Our photosynthetic device doesn’t run down the way a battery does because it’s continually using light as the energy source.”
In the experiment, the device was used to power an Arm Cortex M0+, which is a microprocessor used widely in Internet of Things devices.
It operated in a domestic environment and semi-outdoor conditions under natural light and associated temperature fluctuations, and after six months of continuous power production the results were submitted for publication.
“We were impressed by how consistently the system worked over a long period of time — we thought it might stop after a few weeks but it just kept going,” said Dr Paolo Bombelli, from the University of Cambridge’s Department of Biochemistry, first author of the paper which has been published in the journal Energy and Environmental Science.
The algae does not need feeding, because it creates its own food as it photosynthesises and despite the fact that photosynthesis requires light, the device can continue producing power during periods of darkness.
The researchers think this is because the algae processes some of its food when there’s no light, and this continues to generate an electrical current.
The Internet of Things is expected to grow to one trillion devices by 2035, requiring a vast number of portable energy sources.
The researchers say that powering trillions of Internet of Things devices using lithium-ion batteries would be impractical.
They say it would need three times more lithium than is produced across the world annually and traditional photovoltaic devices are made using hazardous materials that have adverse environmental effects.
The work was a collaboration between the University of Cambridge and Arm, a company leading the design of microprocessors.
The research was funded by the National Biofilms Innovation Centre.

Tailors and retailers miss out on back-to-school rush
Tailors and retailers across the city said it was an ominous start to what is usually a busy season for sales.
With many parents opting to continue home learning for their children, the usual rush to buy school uniforms was muted this year.
“So far we have taken about 70 to 80 orders for items like shirts and trousers,” said Vikram Attrai, manager at Stallion Bespoke Tailors in Dubai.
“Last year in the same period we had about 200 orders and lots of demand.
“We custom fit uniform pieces and use materials such as cotton, wool and cashmere.
“Depending on size, a white shirt with logo is priced at about Dh100 to Dh150 and shorts, trousers, skirts and dresses cost between Dh150 to Dh250 a piece.”
A spokesman for Threads, a uniform shop based in Times Square Centre Dubai, said customer footfall had slowed down dramatically over the past few months.
“Now parents have the option to keep children doing online learning they don’t need uniforms so it has quietened down.”

The flights
Etihad and Emirates fly direct to Kolkata from Dh1,504 and Dh1,450 return including taxes, respectively. The flight takes four hours 30 minutes outbound and 5 hours 30 minute returning.
The trains
Numerous trains link Kolkata and Murshidabad but the daily early morning Hazarduari Express (3’ 52”) is the fastest and most convenient; this service also stops in Plassey. The return train departs Murshidabad late afternoon. Though just about feasible as a day trip, staying overnight is recommended.
The hotels
Mursidabad’s hotels are less than modest but Berhampore, 11km south, offers more accommodation and facilities (and the Hazarduari Express also pauses here). Try Hotel The Fame, with an array of rooms from doubles at Rs1,596/Dh90 to a ‘grand presidential suite’ at Rs7,854/Dh443.

Mane points for safe home colouring
- Natural and grey hair takes colour differently than chemically treated hair
- Taking hair from a dark to a light colour should involve a slow transition through warmer stages of colour
- When choosing a colour (especially a lighter tone), allow for a natural lift of warmth
- Most modern hair colours are technique-based, in that they require a confident hand and taught skills
- If you decide to be brave and go for it, seek professional advice and use a semi-permanent colour

Cultural fiesta
What: The Al Burda Festival
When: November 14 (from 10am)
Where: Warehouse421, Abu Dhabi
The Al Burda Festival is a celebration of Islamic art and culture, featuring talks, performances and exhibitions. Organised by the Ministry of Culture and Knowledge Development, this one-day event opens with a session on the future of Islamic art. With this in mind, it is followed by a number of workshops and “masterclass” sessions in everything from calligraphy and typography to geometry and the origins of Islamic design. There will also be discussions on subjects including ‘Who is the Audience for Islamic Art?’ and ‘New Markets for Islamic Design.’ A live performance from Kuwaiti guitarist Yousif Yaseen should be one of the highlights of the day.
