Scientists have figured out a way to turn heat into electricity using magnets!

October 1st, 2019 at 12:19 pm » Comments Off

  Researchers all across the world are looking for ways to harness heat that otherwise would’ve been lost. They’ve put together ingenious solutions to trap atmospheric warmth and turn it into power when the Sun goes down and solar energy cannot be harnessed. However now, scientists have figured out a method to convert heat into […]



Graphene nanoribbons lay the groundwork for ultrapowerful computers

September 28th, 2019 at 12:03 pm » Comments Off

  Graphene nanoribbons on silicon wafers could help lead the way toward super fast computer chips.

But the 18-month cycle of exponential increases in computing power that has held since the mid 1960s now […]



Thermoelectric generator harvests renewable energy from the cold of space

September 24th, 2019 at 11:29 am » Comments Off

The thermoelectric generator uses a black aluminum disk to radiate heat into the atmosphere, and a polystyrene enclosure to keep the air inside warm.Aaswath Raman  As effective as solar panels are, one of their major downsides is that they only produce power during the day, so excess energy needs to be stored for use overnight. […]



Astronauts make cement in space for the first time

September 21st, 2019 at 1:07 am » Comments Off

European Space Agency astronaut Alexander Gerst works on an experiment aboard the International Space Station looking into how cement reacts in space. Concrete could provide humans in space with better protection from radiation and extreme temperatures than many other materials. In the future, when humans live in and visit space, they’re going to need places […]



Graphene sponge helps lithium sulphur batteries reach new potential
