Hydrogen? You'll need a high compression engine. That is you need different pistons or shave some material off the heads or block or both (race car stuff). Get a junk car, rebuild the engine for high compression, enlarge the fuel injectors for ethanol, high performance plugs and use E-85. Add a turbocharger. That's the closest you'll get to hydrogen.
First off, I don't want a junk car. I don't even want to fiddle around with a junk car because I won't drive a junk car anymore. That's ok to haul firewood but I was no longer able to deliver paintings into really nice neighborhoods without getting odd looks. There's more to a vehicle than just the engine, right? I want to be happy with the finished product and be done when I'm done. So I picked up a nice SUV, an Envoy, with a great body and real smooth.. a 30K vehicle (looks super), I got it used for 7800 bucks since in this economy the past couple years, if you go in with cash you can negotiate some really good bargains. I thought to mess around with this kit (probably will wait till spring now), it does a hydrogen injection into the fuel/air mix, and then hopefully in a couple years, if technology allows, pull the entire engine and reseat something else in there. That's the plan anyway. The last truck I had, I kept it 18 years, did maintenance/minor work on it myself and only took it to it a mechanic for major stuff a couple times over that 18 years ( an old car mechanic friend gave me fix-it lessons many years ago). That was a junk vehicle by the time I was done with it, I was glad to get rid of it for a newer, safer, better looking model. It would have cost me close to 7800 bucks to really revamp that old truck. Maybe I'm dreaming, but it seems to me that so many people are working on this technology, within a few years time I will probably be able to just buy something I can more or less just drop in as a replacement engine for a couple thousand bucks maybe even less. if you hear of anything like that, something I could (more or less) just drop in, definitely let me know. I hear what you are saying but shaving the head etc is not my thing.
that's perfectly fine if you have no intentions of ever buying a new car or living in anything other than a rented place of residence.
I have never owned a 'new' car. Why would I buy a new car when I can get a good used vehicle for half the price or less? A good used vehicle a few years old suits me just fine.
You can buy a house (or car or anything) without a good credit score. The car you should pay cash for. If you cannot cover the house fully with cash, you'll need about 20-25k in cash as a down payment and rarely will anyone turn you away with that much cash.
I cut the credit card up about 15 years ago now. It's the best thing I ever did. It took me a full 3-5 years to regain what felt like a 'balance' to me.. that is, to begin to have enough cash to start doing things again (work and save!) but once I was on the other side of that I have never looked back (and I did it as a single parent btw, with no handouts, no welfare.. there were a couple rough spots). I would not ever go back to the credit card lifestyle.. it's too expensive. I actually have quite a bit more now than I did back then and everything is paid for. When you use credit, by the time your stuff is paid for, you've paid at least twice for it and it's old already. This does not make sense to me. I owned a house in florida but sold that.. we moved up to the mountains here, we do rent (do not own this property) but right now, considering the foreclosure mess I am real glad about that too. We live here on a million dollar (at least) piece of property, I could never afford this even with great credit. So we rent. I haven't got any complaints. There are ways to invest money other than real estate, real estate is not a very good investment right now (my op anyway).
