New Tech Extends Range of Deep Sea Exploration Robots

For much of human history we have explored and lived in some of the most extreme environments on the planet—mountains, jungles, deserts. However, the largest environment on Earth composing 70% of the Earth’s surface, the ocean largely remains a mystery to us.

Only about 20% of the ocean bed has been mapped.

A fuller picture of the ocean would bring many benefits including safer navigating ships, creating more accurate climate models, laying new telecommunication cables, the building of offshore windfarms and of course protecting marine species.

Many refer to this as the “blue economy” and it could be worth an astonishing $3 trillion by 2030.

While underwater robotic vehicles equipped with various equipment have been in service for quite a while and have increased the amount of data we collect and at a lower cost, many of these robots rely on batteries and have to return to the shore or a boat to recharge making it impossible for them to ever map the most remote parts of the ocean.

Yi Chao’s Seatrec startup is working on solving this challenge by channeling the natural temperature differences in ocean waters.

The technology can be attached to existing robots or Seatrec’s own ocean explorers. The device is a float that moves between warm and cold parts of the ocean. The materials inside the module the either solidifies or melts. This causes pressure that turns to thermal energy that power’s the robot’s generator.

 

iPhone Supposedly Working on MagSafe Battery Booster for iPhone 12

Remember the good old days when your phone was running out of juice and you could easily snap off the back cover, pull out the battery and swap in a new one?

Many of us remember owning more than one cell phone battery and when the first ran low we would just connect a fresh one and go on about our day.

For most phone users those days are gone. Now we rely and external batteries and rapid chargers. However, Apple is supposedly developing something better. The rumor is they are working on a battery booster that would attach magnetically to charge iPhones sans-wire and while you are using it.

iPhone developers have been, for the last year, working on a battery pack that would attach to new iPhone 12s with MagSafe technology. Apple has already employed MagSafe to connect their phones to wireless charging pads, among other accessories.

According to sources, Apple had planned to release the product last October when the iPhone 12 was released, however they were still working out software bugs.
