Uprush for space race: Oz solar cars blaze at speed of sunshine

admin — Fri, 18 May 2012 15:14:03 +0000

The world solar challenge car race began on Sunday morning: as 37 teams drove out of Darwin at the start of a 3000 kilometre road trip across Australia. The biannual race sees solar-powered electric cars and vehicles traversing Australia’s interior. As solar technologies and aerodynamics of the cars have advanced, race sponsors have adjusted how much solar the cars could have on them, their size and even how fast the cars can go – they now have to follow posted speed limits and incur time penalties when caught over the limit. This year student-led teams from twenty countries, including the Philippines, Chile, Turkey, Iran and Malaysia were taking part. The journey takes about five days and requires a large degree of self sufficiency.

Solar energy – nuclear fusion in the sun

admin — Fri, 18 May 2012 15:13:22 +0000

How nuclear fusion works in the sun and how photons from this fusion provide us with solar energy here on Earth for things like photovoltaics (solar power), solar domestic how water, solar air heating and solar cooking. Also given is background such as what an atom is and the parts of an atom: neutrons, protons and electrons. Sample atoms are provided: hydrogen, deuterium and carbon atoms.

This is the simplified version that stops at gravity. Version 2 of this video goes into more detail talking about gravity, high temperatures and quantum tunneling:
