Overall I'm quite happy with the result, personally I was leaning towards "yes" so slightly disappointed but it was close enough that David Cameron has already been hinting about devolving more powers to not just Scotland but also Wales, Northern Ireland and England. The Westminster government...

To link in with Bobc's comments. I took Coyote and my son's car "Mjolnir" to the Greenpower final in 2011 in a trailer behind my Kia Cee'd SW, with the 500kg trailer and five people onboard we averaged 51mpg for the 1520 mile round trip. On the equivalent amount of energy the best Greenpower...

The price today in the slightly more populated eastern end of Scotland's north coast was £1.46/litre for petrol and £1.54/litre for diesel, in Durness over at the other end of the coast which is somewhat more remote it was £1.59/litre and £1.71/litre; that's just plain scary! I usually post on...

I built our current house about six years ago, total area is about 200m^2 and it's single storey, we're a family of four so most of the rooms are in continuous use. Construction is timber frame with a block and roughcast outer skin but the frame is insulated with 140mm of polyurethane, same...

We haven't had any races since the last post on this thread, the new season starts on 29th April, but the 2011 Final on 16th October was an excellent race in perfect conditions with the distances achieved being virtually the same as 2010 despite a 30-40% reduction in available power. The car I...

Heavy duty welding drape, usually made from a kind of woven mineral wool might be a better option that laminating fabric. I've used them as a liner for ammunition cases used to transport fireworks to displays, in tests a double layer is enough to prevent a 1kg gerb burning through the case...

I wondered when the valve train was being assembled what it would run on as the crank/cam drive ratio is 1:1 so couldn't be a 4-stroke IC engine and must be running on compressed air or CO2. However a superb demonstration of miniature engineering,I suppose it's an example of engineering as art...

A nice chilli chutney for spicing up sandwiches, soups, stews, etc. 1kg Red onions 6 cloves garlic 1kg medium heat red and green chillies 1/4kg Scotch Bonnet chillies 1/4 litre white wine vinegar 100g sugar salt to taste Finely chop onions, garlic and chillies. Put in pot with vinegar and cook...

Bobc. I forgot to ask, how much effect did you measure from the onboard cameras at Goodwood? I reckon the one on the front of Coyote was adding about 7 seconds per lap, I didn't even realise it had been put on the car until they came round at the end of the first lap!

I had just such a machine and spent a happy three months cycling many thousand miles round France and Spain when I was about 18 years old. It always amazed me how much more lively my Peugeot was to ride compared to my friends bikes which were top of the range (at the time!) aluminium alloy...

In reality Greenpower racers don't use anywhere near the 2.5kwh stored in batteries, Mr Peukert sticks his oar in and limits us to something closer to 1.5kwh. In fact, due to a very inexperienced team, we only used 1.35kwh in this years final and were 4.8 miles behind Bobc's car in 7th.

Biddyd01, another poster on here, Bobc, and myself are both involved in Greenpower through different teams. It sounds like your car has already raced? Which car are you and where are you based? Most of the questions you're asking have been covered many times on the Greenpower forum...

Nice video, very surprised to see races on schools roads with kerbs and lights, I doubt Greenpower's insurer's would agree to that! Interesting that the cars seem to be perfectly stable in the corners despite most being trikes. Are those Etek motors most cars are using? Here's a good video from...

Drew, as Bob say's the NuVinci has had only limited success in Greepower, where it has done well is on tight, twisty circuits where it allows more efficient running over a wide speed range. I suspect, as you've already found, that it may be better to stick with single speed for long ovals and if...

Sounds like we're heading towards similar solutions, we're using both speed and current as parameters, and going down hill the motor may just "tickle" the car along rather than being fully on or off; we think it's better to keep the motor turning to help dissipate heat after climbing. Luke had...
