Driving into the Future

Illustration of the Thatcher effect (c) Alex Dodge

This week, we look into new ways of putting a tiger in your tank!  We find out how pond life could help make eco-friendly biodiesel and how new types of batteries can power electric cars for further than ever before without running out of juice.  Plus, how Margaret Thatcher’s face can tell us how monkeys recognize each other, what sharks have in common with serial killers and why dolphins are a bit like jet fighters.  And in Kitchen Science, we see how batteries work in Arctic conditions.

  • 18:04 - Freezing batteries

    We have a look at the chemistry of batteries and what happens if you cool them down.

  • 27:15 - Racing Green - Electric and Hybrid Supercars

    Electric and hybrid cars do have a bit of an image problem. Many people think they're a bit slow, a bit goody, goody, perhaps a bit worthy, but this week, Meera Senthilingam visited Imperial College London to find out how electric and hybrid cars could soon rival modern petrol ...

  • 34:33 - Bipolar Batteries could be Better

    So far, we’ve heard that electric cars have a great deal of potential but they're held back by their weight, capacity and the expense of their batteries. So new types of batteries are actually essential to seeing more electric cars on the road...

  • 39:54 - Filling Up with Algae

    Now, electric cars are not the only option we have for sustainable personal transport. Already, there are a number of vehicles on the roads that use biodiesel and that’s diesel that doesn’t come from fossil fuel but from living creatures, from living plants. Now, Anna Stephens...

  • 49:27 - How do I save carbon with a new car?

    With the budget introducing the £2000 subsidy to scrap old cars, I'm trying to figure out how much energy and carbon goes into the manufacture of a new car. Considering the increase in efficiency of the new car, how many miles would I have to drive to achieve an overall carbon s...

nat cousins asked the Naked Scientists:

That's not very high mileage!

Your comment that 40,000 kilometres a year is a lot of driving, maybe in the UK, but here in the states that is equal to 24,000 miles a year, = 461.5 miles a week or about 77 miles per day for 6 days a week. or about a 35 mile trip to work plus short trips to stores.  not much here in the States.

What do you think? nat cousins, Mon, 13th Jul 2009

Well the United States (9,161,923* SQ Km) is roughly 37 times larger than the United Kingdom (244,820* SQ Km).
