PUT the kettle on. Hyundai’s prototype selfdriving, zero-emission, Nexo fuel-cell car (pictured) uses a chemical reaction with hydrogen to generate the electricity to drive its motor. The only by-product is water from its exhaust, which, the Korean car maker says, could be stored to brew tea or water plants.

ANOTHER nail in diesel’s coffin this week — Porsche announced it is axing all diesel options from its range because of a ‘cultural shift’ that means ‘demand for diesel models is falling’. It intends to concentrate on petrol and hybrid options. THERE’S still time to pack your kit for the Caravan, Camping and Motorhome Show at Birmingham’s NEC, running today and tomorrow (

AfTer a gentle winter in south and eastern Britain so far this year, the season is ending with a nasty shock. Deep frost is expected for the next ten days and borderline plants which have survived so far are at great risk.

If any of your tender or half-hardy favourites are outside and still alive, it’s worth protecting them. move those in pots into the warmest part of your garden and cover them with horticultural fleece.

They’d also be safer in a building which is frost-free, even if it’s dark. If your plants can’t be moved, try to protect them where they are with horticultural fleece or any lightweight insulating material.

Tender plants such as dahlias and New World salvias, if still in the ground, would benefit from an extra mulch over their roots.

Unheated greenhouses will be unsafe when outside temperatures drop to minus 2c or below. But if fleece is laid over the plants overnight, that can help.

As temperatures plummet, this protection could make the difference between life and death for your borderline plants. So a little trouble could save money and let your plants come through.
