Here’s a little tricky experiment that you can do on your own at home. It’s very simple to do, all you have to have is a solar battery (you can buy that cheaply from a scrap store), a bottle, a toy with wheels you don’t need anymore, and a little bit of super glue.
It runs completely on solar power. Starting from this guy’s idea, I’ll try to improvise a method to recharge my remote controlled toy car from the sun (all big kids must have a RC toy handy, don’t they?)
So, watch the video and start teaching your kid little things. In time, they’ll become bigger and hopefully, if done on a larger scale, save our planet.
Enjoy!

How to build a solar car for your kids
Not only is the sun a source of heat and light, it’s a source of electricity too! Solar cells, also called photovoltaic cells, are used to convert sunlight to electricity. Solar cells are used to provide electricity all kinds of equipment, from calculators and watches to roadside emergency phones and recreational vehicles.

A Soda Can Powered Solar Garage HeaterI found out the ingenuity of some people exceeds “common sense” and their inventions are really helpful to humanity. Not on large scale, but for those tech-guys who do nothing but sit all day long in their garages and invent crazy things nobody would have imagined. Most of these inventions stay there, in the respective [...]
Here’s a short video of someone who modified his bicycle to go electric. He used a brushless motor and a pack of several Li-Ion batteries of 36V capable of 30A (about 1kW). You’ll, see, he uses two, four, six, or eight of these batteries. That’s 8kW = about 5hp. That’s more than a regular motoscooter [...]
Paint Your House With Solar Powered Paint!Two UK researchers, David Worsley and Maarten Wijdekop have made up a paint that could produce electricity by gathering the energy from the Sun. A consortium led by Swansea University in the UK hopes to use that process to cover steel sheets with a photovoltaic paint at up to 40 square metres per minute.The paint [...]
A Solar Powered Boat – the perfect gift for a summer's dayWould you like going on your nearest river or sea or ocean in a summer day? Would you like cruising all day powered only by a solar battery? Well, for 10,500$ you could. Hammacher Schlemmer has built a small solar powered boat for two person. Because the batteries hold up to a 6-hour charge, the [...]

Great ideas, very helpful. I have been really nervous about helping my daughter out with her science projects, this is not something I have been looking forward to at all. Thank you for this post.

Fill that bottle with water and you’ll see what is the problem with solar power: it’s not powerful enough. That’s why there’s not a single sun powered car to carry more than a person. It’s great for a science project but (unfortunately) it’s not applicable a real car.

that was asume that was the coolest bottle moving solar car ever but with no steering … LOL

I MADE THE CAR
#10 by Bang on May 22, 2009 - 11:24 am
Yo Yo Yo! hold the phone, this is cool alright but the only problem is that you cant turn that thing and it cant save the solar energy it just ate up and put it to waste.Now if you want a real car check out ma site in which you can know more about auto mobilos
#11 by AK on May 22, 2009 - 11:19 am
I think you should buid a car (for adults)that runs completly like a wind0up toy,the only difference would be that you could control the wind-up key.
#12 by Michael on April 14, 2009 - 11:20 pm
that was a waste of time and this is the same video that’s on ehow.com
#13 by Kelly on January 14, 2009 - 1:54 am
how long does it work and is it a good energy sorce and does it need sun or can it be like a modal car and do the wires please tell me
#14 by David on January 11, 2009 - 7:47 pm
I like it, but its only a start?!
Lets make one to were it can turn, then we have something?
All in all its great. just email me with ideas on how to stear it> thyanks and wating at dmfi84@gmail.com
#15 by Josie on December 16, 2008 - 4:02 am
just watched it again it was marvelous and a science fair for a fourth grade student with that project first place woo winners r us. lol
#16 by Josie on December 16, 2008 - 4:00 am
wow that blew my mind it was challenging yet fun to try and do.First place science fair here we come
#17 by Philip on December 7, 2008 - 10:50 am
Hey, thanks for the tips on how to make it but what is the white plastic you put the motor in? Can I find that in any R/C car?
#18 by admin on December 7, 2008 - 11:07 am
i guess you can find it in any electric toy car… just see if it fits the motor
#19 by Poirshea on December 3, 2008 - 12:06 am
Thanks 4 the tips! I am trying to figure out what science fair project i will do so i could really use all the help and resoces i can get! I will tell all of my friends and family about this website!
