Topic Prompt: If you could invent a few inventions to solve the world’s problems, what would you invent?  In other words, what will be the most important inventions in the next 100 years?

Title:  Important Inventions in the Future

We often wonder what will be invented in the future to improve our situation. Albert Einstein noted, “We can't solve problems by using the same kind of thinking we used when we created them.”  In the last 150 years, many inventions in communication, transportation, health and agriculture have solved various problems in our world and brought our entire planet closer.  Specifically, the computer, cell phone, automobiles, vaccines, and improved farming techniques have made most people’s lives easier; however, problems still exist in the world.  Many people lack access to clean drinking water, a pristine environment and higher education.  Therefore, in the next 150 years, more inventions need to be created to improve the lives of many, and the following inventions stand out as being the most useful for our future.

One of the biggest problems needing a solution is for everyone to have access to clean water.  In fact, according to the Centers for Disease Control and Prevention, about 1 in 6 people, or “1.1 billion persons worldwide lack access” to purified drinking water.  Therefore, one of the most important and dramatic inventions will be a ‘Water Generator’, a manageable device that can quickly generate water as abundantly as splitting an atom generates energy.  Whole rivers and streams could be created or replenished in an organized fashion with this eco-friendly ‘Water Generator’.  Agriculture and farming would flourish, and then everyone in the world could have enough healthy food to eat.  In addition, easily preventable diseases such as dysentery would be completely avoided.

Every day the land and seas are polluted, resources are over-utilized, and animals are left with fewer habitats.  To overcome some of these problems, tiny but powerful ‘Solar Energy Packs’ could be invented to charge every mechanical device in businesses, homes and transportation.  These small solar packs would be less polluting than regular batteries, oil or gas, because they would be rechargeable, even in cloudy weather. Cell phones, refrigerators, cars and trains would all run on ‘Solar Energy Packs’. In addition, an organic solution to pollution could be created, with ‘Pollution-EatingBugs’ helping to clean land and sea. In fact, according to a Science Daily article from 2005, “biomediation” of oil spills may already be developing.  With ‘Solar Energy Packs’ and ‘Pollution-EatingBugs’, we can more effectively conserve resources and the environment.

In order to combat illiteracy and unemployment, a new program called ‘EduTube’ could be invented.  ‘EduTube’ would be like YouTube but teachers and other students would interact with each other directly, using new styles of teleconferencing software to connect.  ‘SmartTops’, a cross between a SmartPhone and a LapTop, would have libraries full of educational resources available on them.  Students would no longer need to carry heavy books or travel long distances to learn.  Materials would be free and accessible to everyone with a ‘SmartTop’, which would be as ubiquitous and cheap as a calculator is today.  For job seekers, vocational training or learning a new skill would be easier using ‘EduTube’ and ‘SmartTops’.

In conclusion, in the future, many inventions will change our relationship with the planet, with each other, and with our own learning.  With access to clean water, fresh produce, a purified environment, and education, more people will stay healthy, happy and wise.  Bruce Lee once said, “The future looks extremely bright indeed, with lots of possibilities ahead -- big possibilities. Like the song says, ‘We've just begun’”.

“The cars as they are, with energy recovery systems, for a human being are pretty undrivable, unless you have the technology there to make them drivable,” said Pete Highton, the principal staff engineer for global sales and marketing at Freescale Semiconductor, a Texas company that works with McLaren on the E.C.U.

“You have rear-axle braking, which is generating energy for you; that doesn’t feel like normal braking,” he added. “If you ever see it come on, it comes on in a great big clunk. The technology helps the driver to fine-tune that.”

Surprisingly, the consolidated unit is also helping shift control of the car away from electronics and back to the driver — since the Belgian Grand Prix, for example, drivers, not engineers, select their own gearshift ratios — and that, in turn, means the software itself has to be more automatic.

“It’s pushing the onus on not only the driver, but the stuff that’s going on in the box, to be more autonomous and without the aid of the team,” said Tim Strafford, the commercial director of McLaren Applied Technologies. “There is more responsibility to be taken on by those applications that the engine manufacturers are developing themselves, where rather than taking a mode control change manually they have to become more intelligent.”

“There will always be lots of high-tech stuff in Formula One,” Strafford said. “And it’s really controlling where that high-tech is, and where you are allows the flexibility to innovate.”

“And with these systems we have now, it is enabling the F.I.A. to choose where they want to allow the innovation and where they want to lock things down,” he added, referring to the International Automobile Federation, the sport’s governing body.

The E.C.U. has changed the way that the teams handle the masses of data involved in elite racing — more than 100 gigabytes of data are produced at each race by a Formula One car. In the past, engineers would send huge amounts of data from the car to the team’s garage and factory for processing. With the E.C.U., however, much of the data is processed in the car itself, saving precious time and making the car smarter.

At the heart of the E.C.U. are the processors that are provided by Freescale, which as a Motorola company in the 1960s provided processors to the Apollo space program. Freescale engineers work closely with McLaren Applied Technologies engineers to develop the units.

Freescale is also one of the world’s biggest providers of processors to road cars, working as it does with most of the equipment manufacturers that provide technology to road car manufacturers around the world. This means that Freescale’s technology can be found in virtually every car on the road today.

So, it’s with the road cars in mind that Freescale is attracted to Formula One’s specific environment — not as a sponsor or for marketing purposes. (The company’s name does not appear on the racing cars.)

“What you are looking at is a parallel hybrid system in a racing car,” said Highton, the Freescale executive. “That’s very similar to the parallel hybrid system that you see in the green cars that you have now, and what these guys do is take those systems and push them to the absolute limit. When you do that, you reach a point at which you say, ‘Wouldn’t it be really good if the processor could do this?’ At which point, I appear and go, ‘Sorry, say that again?!’ Because at that point, I can second-guess where your standard green car is going to be in 5 to 10 years’ time. And I can put that functionality into a piece of silicon. That is worth a lot of money.”

The concept of placing all the control units in the same box, rather than having them spread throughout the car, has begun to catch on for today’s road car.

“That sort of concept of more consolidation is very much the way the automotive industry is trying to go, although it is in its early days,” said Strafford, the McLaren Applied Technologies executive.

But what remains to be determined is which systems in the car need their own individual unit and which can work through a central box like the E.C.U.

“We have some of the boxes that are on the McLaren road cars, and we have started moving those cars in that direction,” Strafford added. “We have one box on that car which controls different features which in the past would have a separate module for every single one of those functions — maybe five different functions would each have their own box.”
