The whole history of car manufacture has been one of ever increasing specific power outputs. At each step of the way I imagine every generation has had the same thoughts about too much power from a small engine and yet the 6.8 HP per litre for the model T has increased to a record of 354...

Because the energy absorbed by the turbine wheel equals or exceeds the energy needed to drive the compressor.

The preliminary report is out and crazy as it seems the fuel was cut off to both engines by one of the pilots, they are not saying which. The action was questioned by the other pilot and one engine restarted but too late to recover the plane.

For this recent story about the fuel switches to be credible it would imply a leak from some person closely involved with the investigation. Is that likely ?

Used engine oil is classed as carcinogenic for skin contact rather than inhalation but I still don't think I'd want to breath the fumes for too long.

A notable disadvantage has been that debris from an engine failure has either taken out another engine or severed control hydraulics.

I don't think we were in any doubt that the pursuit of net zero was behind the blackout some how but the actions of the solar generators shutting down on economic grounds was willfully destabilising for the grid and they didn't seem to care. It's not just that net zero seems to be recklessly...

It's a nice pub too, an original coaching inn dating from 1730.

I've lived in the same house for 32 years. It's in a small village but has a convivence store, pubs. restaurants, a post office, a doctors surgery and a dentist. In short it's a semi rural area with good amenities. Over and above these conveniences, the one thing that makes me like where we...

I appreciate it is accurate on a known route or type of driving but what if it doesn't know you are about to drive up a 6% grade. What would be really useful is to know what impact a 6% grade will have on the cars miles per KWh. I've heard anecdotal evidence that Miles/kWh goes through the...

I treasure memories of holidays over the last 50 years in many European countries and in the US and Canada. One things for sure is that they haven't improved over time. These days I have an overseas holiday in March and early October when the weather is reasonable and the destination free of...

Ate SL6 fluid comes in cans. A BMW dealership will sell fluid in a can but I expect it's $$

I was thinking the same. It has to be worth experimenting with a different adjustment or checking the adjustment when the bearings are hot. taper roller bearings have the longest life with a small amount of pre-load but the life falls off a cliff if the pre-load is too high.

When you throw in the fact that modern cars rarely finish a journey with a fully charged battery because of the smart alternator, I wouldn't dream of letting one sit for month without driving it or a top up charge. My Last MB would sit at the airport for a week but even that made me nervous and...

The first thing that comes to mind is that a hiker carries his own water and even 1 days supply of water is seriously heavy. Is there really more to the saying than that ?
