If we use fuel to get our power we are living on our capital - this method is barbarous.

CUTTING OUT FOSSIL FUELS BY BUILDING COMMUNITY
The urgent need to slash today's extreme consumption of fossil fuels is not a numbers game, nor is it a matter of degree. Rather, it is a matter of reduction in kind.
We cannot break our hyper-addiction to our fossil-fuelled economy of hyper-consumption incrementally, or gradually, or by means of some pain-free twelve-step program. We have to go cold turkey wherever we can. Right now. We have to begin by taking a good hard look at every single thing we do - at every single thing we have, at every single thing we want. Then we have to start the hard job of cutting out every single thing we can do without. http://i.am/jah/environ.htm
The surging demand for corn, sugar cane and vegetable oils to make Earth-friendlier biofuels is pitting hungry cars against hungry people, and troubleâ€™s brewing, says sustainable development pioneer Lester Brown.
"...In effect what we have are 800 million motorists who want to maintain their mobility and two billion people who want to survive,..."
A Scotsman is driving round the coast of Europe in an eco-friendly van that runs exclusively on waste vegetable oil.
Antony Berretti arrived in Gibraltar on Sunday as he completed the latest leg of his trip from the French port of Calais to Brindisi in southern Italy.
Mr Berretti has vowed not to spend a single Euro on fuel during his trek across Europe.
Instead he relies on the owners of restaurants and cafÃ©s to provide him with the contents of their pots and fryers at the end of a busy day in the kitchen.
He spent yesterday touring the Rock and persuading friendly local restaurateurs to hand over their used oil.
He is pictured above with Roy Walker, owner of Royâ€™s Cod Plaice in Casemates, collecting 30 litres of oil which will end up in the tanks of his converted Fiat Scudo 1.9 Turbo Diesel van.
Used oil is regarded under law as a waste product and restaurateurs normally have to pay to have it collected and properly disposed of.
â€œItâ€™s not waste,â€ Mr Beretti said. â€œItâ€™s a valuable resource.â€
With this trip, Mr Beretti wants to generate awareness of practical, sustainable alternatives to fossil fuels.
Vegetable oil, he said, is â€˜cleanerâ€™ and cheaper than diesel, as some progressive countries have already discovered. In Germany, for example, drivers can even buy it from pumps in petrol stations.
And Mr Berretti insisted that such fuels are easy to use. He converted the van himself and built his own pressure filter â€“ essential when using waste oils - using what he described as â€œgarden shed technologyâ€.
All the materials he used were re-cycled. Even the van itself was saved from a scrap yard.
So far, Mr Berretti has made good speed. He started his trip in Calais 13 days ago and expects to arrive in Italy in just a weekâ€™s time. Readers can follow his progress at http://www.macharsoft.co.uk/freefuel

Comments to CLEM1.ASC (KeelyNet) by Josef Hasslberger
Richard Clem's rotational engine
Although I do not have any information on Clem or his device, I would like to comment on the principle of operation, which seems quite simple and straightforward to who has studied the writings of Viktor Schauberger, the Austrian naturalist and inventor.
Indeed Schauberger was working with vortex action in liquids (especially in water) and was finding effects that were at the time, and are still now, unexplainable with the normal principles of physics or thermodynamics.
As far as I understand the engine made by Clem was built around a cone with spiralling channels cut into it and when a liquid, in that particular case vegetable oil, got pressed through the channels, they caused the cone to turn and at a certain point the flow of the liquid and the turning of the cone became self-sustaining, up to the point of putting out a good and heavy (350 HP for a 200 pound engine) power output.
China's insatiable demand for proteins as well as oil is turning Brazil into the takeaway for the workforce of the world. In the second part of our series, we reveal how the soya trade is creating a gold rush which is deforesting the Amazon
"...Today the food system is even more reliant on cheap crude oil. Virtually all of the processes in the modern food system are now dependent upon this finite resource, which is nearing its depletion phase."
Climate change over the next 50 years is expected to drive a quarter of land animals and plants into extinction, according to the first
omprehensive study into the effect of higher temperatures on the natural world.
