One of the many problems with space travel is how we measure speed.
Speed is relative – as this very good Ted video shows.
One of the problems facing human space travel isn’t travelling fast, it’s getting to that speed. The g-force excreted on the body whilst accelerating poses major health issues. So even thought we may be able to invent ways of travelling faster, unless we can control the g-force, its pointless going faster, as if we get to a fast speed too quick (accelerate too fast) the people travelling at that speed will die.
If you are driving a fast car and you very quickly put it into a lower gear and put the accelerator to the floor, you feel yourself fly into the back of your seat. If you are travelling at 60mph your body feels fine, as it does at 0mph, however in the few seconds it takes to get you there, you are subject to huge g-force’s.
Travelling from 0-60mph in 30 seconds puts the body under a lot less stress than if you do it in 3 seconds. It’s the same with space travel, the body can cope with moving reasonably quickly, however it cannot cope with getting there too fast.
Those who enjoy F1 may remember Kimi Raikkonen’s horrific 150mph crash at Silverstone this year. For a matter of seconds the Fin had 47 Gs of force excreted upon him. For an F1 driver, 150mph is not an unusual speed, however spinning at that speed and coming to a sudden stop caused the dramatic force that Raikkonen endured. Had Raikkonen been spinning with 47 Gs of force for over a minute, the likelihood is he would have died, however because it was only for a short period of time, he was able to race again two weeks later, having sustained no lasting injuries.
Unlike us, robots can be built to sustain such forces, which is one of the reasons why missions like Rosetta and Voyager can see probes sent huge distances in (relatively) small periods of time.
Lets hope in the near future someone discovers a way to keep g-forces at bay, to enable us to travel further into space, faster!
Petrol cars have no future. That is a fact, in 50 years time there will be no crude oil left on planet earth (assuming current consumption rates don’t decrease) therefore there will be no oil left to make petroleum or diesel.
Biofuel, hydrogen, LPG and electric cars are the future, there is no doubt about that. Right now there are many hybrid cars which use petrol with another power source, but in the future, petrol from natural oil will be no more.
There are of course other ways you can power cars, using compressed air is one method as is water-cell technology. These are not however currently concepts in mass production. If you follow those two links, you will find posts written by Jonny on the concepts mentioned.
Arguably the greenest option for the future is electric cars. The electricity used to power the cars can be generate from renewable sources, (it isn’t necessarily, but that is an option) and electricity from renewables is a lot less damaging to the planet than energy generated from the extraction and burning of fossil fuels – be it in on the micro scale inside an engine of a car, or on a macro scale in a network of power stations.
Electric cars are starting to look more and more normal, (in the past some have looked somewhat abstract!) and are becoming more efficient every year.
The Future Car Challenge
This year, British Gas (the company who installed Remote Heating Control in my home) became an official partner of The Future Car Challenge. The Future Car Challenge is an annual event, which showcases the latest developments in the electric car industry. This year, members from the British Gas team drove fro Brighton up to London, with the aim of using the least amount of energy as possible, using the latest electric cars. The team included comedian Robert Llewellyn, Ben Collins, (A.K.A. ‘The Stig’), and Commonwealth gold medal swimmer Ross Davenport.
British Gas are setting up a national charging network, to help increase the viability of electric cars. A charging network is as vital to electric cars as service stations are to petrol and diesel cars. Some electric cars do have the ability to transfer energy generate from breaking into electricity, (as seem in Formula 1 cars) however this alone isn’t enough to power them, so electric recharge points are essential.
Here is a statement from British Gas on their involvement with electric cars:
“British Gas is dedicated to making the world a more sustainable place now and in the future. We are leading the way in providing expertise and charging solutions in the Electric Vehicle market through partnering with Nissan, Renault, Hitachi Capital, Toyota and Vauxhall.
British Gas’ dedicated charging solutions are safer, convenient and more compatible than plugging electric vehicles directly into the mains supply socket at home. Not only do we offer charging solutions that can cut charging times by around a third, but British Gas also offers its customers specially designed tariffs to help them charge for less.”
To celebrate the event, we have five solar power car sets to giveaway, courtesy of British Gas!
The prize is a John Lewis Solar Go Go Car, (click the link for more info) a cool kit from which you can build your own solar powered car! Okay it isn’t quite as good as an electric car, but it looks great fun, and could make a fantastic Christmas present…
The giveaway will run for 8 days, from today until the end of next Wednesday (12.00am on Thursday the 13th).
The prizes will be sent out by British Gas to the UK only, so if you don’t live in the UK I am afraid you can’t enter. If you have an address in the UK you can get the prize sent to if you win, you are in!
