Cloud computing and improved sensor technology could save lives and money, according to Former Apple and Pepsi-Cola CEO John Sculley.“I would imagine in the next ten to 20 years the quality of sensors will be improving healthcare in ways we couldn’t imagine,” he said. “Healthcare missed the PC revolution. It missed the internet revolution. It cannot afford to miss the sensor and cloud revolution.”Mr Sculley was just one of several speakers who took to the stage at Southampton Princess this weekend as part of TedX Bermuda.The business leader, who grew up here in Bermuda, said that advancing technology would revolutionise healthcare by being able to collect and process medical data in real time.“We are on the threshold of an emerging information technology that has the potential to change almost everything that medical professionals know about medicine,” Mr Sculley said.He explained that through the interconnection of devices, a rapidly increasing amount of data is being collected about people’s behaviour, creating massive data centres known as “the cloud”.More and more, he said the computation for personal devices is done in the cloud rather than the device itself.“It’s building the most comprehensive database that the world has ever seen at a scale we couldn’t have imagined even a decade ago,” he said.He noted the numerous sensors built into mobile devices such as iPhones.In the future, he said more and more the sensors will be separate from the devices, providing the cloud with unstructured data.In the field of healthcare, he said such technology can be used to monitor health conditions.Sensors now being developed, he said, are capable of collecting from skin the same type of data typically collected in blood tests, and stream it in real time to mobile devices and, in turn, the cloud.“Why would anyone want to do that?” Mr Sculley asked. “Well, ten percent of the population in the united states are what we call chronic care patients. They represent more than two thirds of the healthcare spent in the US. They are the ones who have multiple disease-state problems.“They are the ones who have the hardest time losing weight, they have things like type two diabetes, sleep apnoea and cognitive heart failure.“You can use this information to predict that this person is likely to have a stroke for the following reasons in the next eight days. That is an incredibly important piece of medical information.”He said the information could then go back to the patient, potentially saving their lives or improving the quality of their lives.Hundreds of people attended the five-hour event, which featured ten speakers, along with musical performances by Heather Nova, K Gabrielle and a spoken-word performance by Kase.Other notable presentations included a talk by geophysicist Ross Stein about efforts to better forecast major earthquakes by mapping historical quakes.By better quantifying the likelihood of an earthquake in an area, he said people are able to build structures accordingly, saving thousands of lives.He noted in once case seeing a building that had collapsed in an earthquake and discovering that styrofoam rather that rebar was reinforcing the corners of the structure.“The world would be a better place if concrete was translucent,” he said.Sossina Haile, Professor of Materials Science and Chemical Engineering at Caltech, meanwhile discussed what should be done to allow solar energy to reach it’s full potential.She noted that one hour of the sunlight hitting the earth is enough to power the entire planet for a year, but there are numerous limitations to the current technology.Current solar panels are limited to collecting certain wavelengths of light and the batteries used to store the electricity are inefficient compared to fossil fuels.Other notable speakers included Eric Barnhill, who discussed using music to help those with learning disabilities, freediving record holder Hanli Prinsloo on people’s connection to the ocean and the Bermuda Sloop Foundation’s Alan Burland on the importance of Bermuda’s nautical history, and the foundation’s role in education.
