Logitech announces the K750 solar powered keyboard

In a move that makes you wonder why a company hasn't tried this before, Logitech has announced the K750 Wireless Solar Keyboard. Yes, solar powered keyboards are here, which means we can finally do away with replacing batteries in keyboards or recharging batteries to keep our peripherals fully powered. But, how well it will charge in a low lit environment or underneath a basic desk lamp no one knows and how it stands up to the daily grind of being used all day still remains to be tested.

This keyboard charges itself whenever there is light and stays charged for at least three months in total darkness according to Logitech. It'll be interesting to see how well the device keeps to these benchmarks once we get our hands on one in the future. The K750 Wireless Solar Keyboard charges up thanks to two large solar panels at the top right and left of the keyboard.

As with a lot of Logitech keyboards, the device is very thin and streamlined at only 1/3 -inch thickness and runs on 2.4GHz Wireless. The keyboard also comes with a Logitech based application called "Logitech Solar App" which informs the user just how much battery power you have as well as letting you know how much power you are drawing in through light sources around you.

The K750 Wireless Solar Keyboard is due out later this month and is currently available for pre-order at $79.99 directly from Logitech.

Thanks to Neowin User EL1TE for the tip.

Cool but you'd think someone would have made keyboards generate power by the speed of your typing. Yeah, that will encourage people to bump up their WPM rates!

Just get a solar powered battery charger... basically the same except you can keep your current keyboard, charge your mouse too.

They should put these in optical mice, then the batteries could charge off the red LED.
Infinite Energy!

If you can see the LED, then some energy would be lost.

solar panels are only around 30 percent efficient so it wouldn't help...

and LED's themselves are not 100% efficient either... nothing is

You all people saying this is useless and/or pointless don't realize what it means for big companies: no more batteries (buying them and paying for the disposal). Think green and think smart people.

Yeah think some people missed the point that its an environmental issue and not about the cost or pain of replacing batteries

it would have been even less of an environmental issue if they just used plain old wired keyboards?

Lol...exactly. Why do keyboards need to be wireless? Are we that annoyed by wire clutter?

Hon, could you please hold this lamp and not move for the next 4 hours while I code?

My solar powered calculator works in very dark rooms... Why would they sell a keyboard like this for such a price that makes it look well built and worth it? Obviously it doesn't need to be in a sunroom all day, neither a well-lit room. All it needs is a tad bit of light energy for it to function.

I can see a significant return on investment for large companies switching all keyboards to this and eliminating replacement batteries.

Or they could just stick with their wired ones.

Um sure. Unless your a company that wants or needs wireless keyboard...

and what kind of company would want a wireless keyboard so badly that they resort to a solar powered one to save money on batteries?

i did lol

probably because it's not the greatest thing since sliced bread. on a decent set of batteries you wont need to replace them for a year or longer. and my current keyboard is backlit for lights-off use, so once again: meh.

Wonder how well these will charge from the glow of an LCD.....

Nice not having to replace batteries but I usually don't leave lights on when I'm not around my computer, so the only time it would be charging is when I would be using it, which would also be using the battery.

Ya, cause I make sure my computer is in a very sunny place... because I love those glaring sun rays on my screen..... Eh, maybe while you are away, just set this on the window sill or something... but I don't see this working with my of those who use their computer in a house.

It can make use of artificial light such as ceiling lights and desk lamps

I'd like to see this used to test it. If it could do that, it might work.

Sun is not the only source of light around, anyway the solar is not the primary power supply, thats the battery. the battery is charged via solar which. solar also supplements the battery supply

Pretty cool in my oppinon

Don't see why it wouldn't charge via artificial light. Plenty of solar-powered devices already do that anyway. Technically speaking, they should be called photo batteries instead of solar ones, as they react to any light, not just sunlight. What I'd like to see is how long it'd last through a constant use of say... 60 WPM with a full charge rather than how long it can keep its charge while not being used.

its the same idea as those old cheap calculators.. i never did my highschool math in the sun but they always seemed to work

Similar to how ambient light calculators have worked for years.
