Matt." You do not need too long to see something new in the air. There are already Brazilian planes with aviation engines certified for ethanol use. The first was a crop dusting aeroplane Ipanema, later some of those engines were available for other small planes as I read lately in a local newspaper one of them was used here as an ambulance plane for poor people in remote areas. The Brazilian Air Force is looking for certification of its T-25 basic trainer with a ethanol powered engine. Engine consumption is 30% higher but for the same size deliver +5% more power compared with aviation gasoline but flying with ethanol was 25% cheaper because ethanol is much cheaper than av-gas. If you live in North America, the pumps at the nearest airfield would not have av-ethanol right now so you might need to carry your own fuel. See the site from the Brazilian aviation builder: http://www.embraer.com/ http://www.embraer.com.br/institucional/download.asp?onde=download&arqui vo=2_083-Prd-VPI-Ethanol_Ipanema_Certification-I-04.pdf http://www.embraer.com/english/content/imprensa/press_release.asp?press_ release_id=880&ano=2004 http://www.embraer.com.br/institucional/download/2_053-Prd-VOP-Ipanema_W ins_Flight_Intl_Award-I-05.pdf Other links with more information are below, they are in Portuguese or English ETHANOL-FUELED IPANEMA CERTIFIED BY THE CTA http://www.defesanet.com.br/embraer/neiva1_e.htm CTA certifica 1o aviao militar a alcool http://www.defesanet.com.br/fab/cta_alcool.htm http://www.defesanet.com.br/embraer/ipanema_sci_ame.htm http://www.defesanet.com.br/embraer/ipanema_sci_ame_ee.htm http://www.defesanet.com.br/fab/cta_alcool.htm Best Regards.

My neighbour is taking a keen and reasoned interest in my endeavours and suggests his next vehicle will be diesel so he can take the same route as I. I would have no problem sharing my BD with him if the net effect of two cars on say, BD50 is better than one on BD100, even though I would reluctantly have to take some from the pumps. My biggest issue is that I love to fly. Almost all aeroplanes still use leaded avgas in very old, mega-inefficient engines. So, all the work I may do to reduce my nasty emissions every day is probably cancelled by the one or two hours flying I do every month. Yes, there are diesel 'planes coming on to the market, but what we really need is bio jet fuel which probably won't happen in my lifetime given the speed at which the aviation regulators work.
